If you are planning on cutting more than one or two metal panels, you may want to purchase a metal cutting blade specifically designed for this purpose. (and you won't have to put one of those on backwards ) 😃- My favorite brand circular saw blade is IRWIN: Amazon Partners Link: amzn.to/3sDG39j
I used the above method 15 years ago with a diablo 80 tooth blade not turned backwards. I would cut five sheets at a time, and the edges of the cut sheet were not sharp but smooth. I had a similar jig setup as I did a building of 120 ft by 60ft. A major project for an amateur.
Thanks for the video!! Two things I did. Flipped the sheets upside down. Made for easier cutting without the ridges. Also, I cut two at a time. Made the sheets more rigid for easier cutting, plus it went twice as fast. Thanks again. This was a time saver!!
We did this at Morton Buildings. The only thing we did different is that we put the metal upside down so you have a smoother surface to cut rather than up and down on the high ribs. I actually just did this today putting a roof on our new front porch.
Thank you very much you're a life saver today I didn't know how it would if I had to cut it by hand. I followed your directions and made a perfect cut thank you very much!
Thanks for the instructions. Worked great. I had to go slow and let the saw cool a couple times but my tiny 20V 5.5" cordless was able to complete the job.
Your welcome - I keep an old blade around to put in backwards - Don't know if it would dull a new blade or not - Have fun and be careful... Thanks for tuning in to our channel
Your table is a nice setup. I’ll definitely use the idea for the moveable ladders. One thing that I learned is to turn your metal over and cut on the backside. It saves you from scratching the top and it’s also easier to cut because you don’t have to move your saw up and down over the ridges. Thanks for posting the video.
I had to rip an 8 ft long piece of metal roofing. Thanks for letting me know I could use a circular saw with the blade on backwards! I have a metal cutting blade, but this is a great trick to know.
We have a storage facility and have been adding some demising walls. Wish I had seen this sooner cause these end pieces would have been so much cleaner and easier to make custom cuts. Definitely going to try this. You tube for the win!
This certainly makes cutting metal easier without the $50 expense of a specialty blade - Just use an old "good quality" carbide tipped cross cut blade in backwards -works great.
Thank you for the demonstration. I love your set up, but just the same I will probably invest in a metal cutting blade. I think Dewalt has one for about 16 bucks. Thank you for making the video.
You can cut that sheet really easy with a 5" disk grinder and an ultra thin cutting disk. Do it on the ground so you are right over the sheet and freehand it along a sharpie line. You will be amazed how easy it is, and how straight you can cut it.
Hey I just want to thank you for this video I picked up a side job skirting in a metal building and I've never really worked with metal before as far as building metal goes and this really allowed me to save a lot of time and give the customer a good bid.
There are very few if you go slow & only cut one sheet at a time - I always try to cut the edge that goes up into the roof peak cap or into the sidewall flashing leaving the factory edge exposed 👍
@@chad6504 Good to know - I learned this technique from a contractor 30 years ago and have never tried anything else because it’s always provided good results ✅
@@homesteadireland7473 I wouldn’t recommend it - you would be pulling the saw towards you & wouldn’t be able to control any “Kickback” that may occur from the circular saw 😭
Yes - They make carbide blades specifically for metal cutting - I have a link to one in the description - I just used an old carbide tipped crosscut wood blade in backwards that I had in hand at the time👍
I flipped the roofing over and cut it from the back. This prevents scratching up the roof and you don’t have to deal with the ridges and your marks show up better on the white backside
Done it a ton of times like this. Super loud. Like stupid loud. Also hot firey little pieces of burning hotness flying everywhere. Safety glasses a must. I like muffs or ear plugs too. Works great. Use an old blade
The most I have ever tried was 2 cheets at a time. Which made the edges more ragged than cutting a single sheet. Assuming you are going to use either a ridge peak or a shed roof sidewall flashing you can always plan on cutting the upper side of your roof panels so that the cut edges get concealed - have fun with your project.
Awesome for I’m building a 12x12 shed and I’m thinking about doing a metal roof for I don’t have to left shingles. For my flooring frame is is a couple of feet above ground and my roof pitch is 30 degrees
They make a metal cutting blade specially for this - They cost around $40 - That’s why I use an old cross-cut blade for wood that I put in backwards - Saves the $40 for a blade that would rarely get used
I used an “old worn out” Irwin 40 tooth carbide crosscut blade (for wood) that I installed backwards instead of buying a new metal cutting blade (that would have been used very infrequently) 👍
@@ClearCreekCabinMiniFarm A plywood blade has less kerf so less metal is being cut off, I don't know if it is better as I have never used a regular blade. As you know, wear ear muffs as it makes a god-awful sound cutting, if you have close neighbors, they may not invite you to the next BBQ!
@@vnyeu Ouch! That is dangerous. You don't want one of those teeth hitting you in the face! I use an old plywood blade, not carbide teeth but many small steel teeth. Running it backward, it burns through the metal rather than cutting it. I always wear goggles when cutting metal.
Can you do the reverse blade thing with a Carbide tipped blade? I'm not sure if it would knock the soldered tips off if they are hit from the opposite side they are designed to use for cutting.
I’ve always used an old 7-1/4” Irwin Marathon 40 tooth carbide tipped blade & never had an issue on small projects - I would think a good quality blade should be okay but I would avoid a cheap one - in any case be careful - safety 1st👍
Just getting ready to metal roof my garage, and need to cut 1.5" off each sheet as they didn't allow for my ridge vent. Is it worth covering the cut sections with something? I was thinking maybe a galvanize spray?
Wow that's a shame - I wouldn't recommend cutting off such a small strip with a circular saw though. I would think that pieces could dangerously fly off at a high rate of speed. Any time you cut a finsihed (coated) metal you risk exposure to the elements unless you recoat it. I would think a foam brush touching up the cut edge with a cold galvanized wouldn't cause an overspray on the rest of the panel that a spray can will?
@@ClearCreekCabinMiniFarm Yeah I'm not thrilled about it. My options are to perhaps leave 1.5" sticking out over the edge, split the difference and have 3/4" sticking out and 3/4" X2 as a ridge vent, trim them, or skip the ridge vent and put in gable vents. There's a bonus room in the trusses, but I don't plan to insulate it, just the main area. I do have a diablo blade for my circular saw that I was planning on running to cut them... and having them stacked tightly and mask for overspray.
You, Sir, just made my week. I have about $3000 in used barn tin to cut, and I'm sure you know how much tin that is. I was NOT looking forward to doing it with tin snips or an angle grinder.
I started cutting steel siding in 1980 with a backwards blade in a skill saw. It always left burrs. If the blade heated up ypou could not cut a straight line. It won't cut wood if you turn it around. It will burn wood. Buy a steel cutting saw from Dewalt with a 50 tooth ferrous metal blade. Also wear hearing protection and a Face shield. Hot metal coming off these saws can burn into your skin and stick to it.
gret video thank you. So basically I do not have to buy a metal saw blade just use my Wooden blade?? and turn it around as you said? the blade i have now only cuts wood? so by turning it the other way it cuts Metal too?? thank you Rachael from New Zealand
Be careful if you are using an inexpensive crosscut blade - I always use a high quality carbide blade that has been well used - cheaper blades can have the tips come off when doing this - And I don’t use the blade ever again for wood work - only for metal (in backwards) or dispose of it 👍
Great vid … roofing a deck this weekend. Does it matter what kind of blade you use in reverse. For example would a multi toothed blade be better than a framing blade?
Hey, good luck with your roofing project - I have always used a 40 tooth carbide tipped cross cut blade for general purpose framing and fast wood cutting (Irwin makes a good one) So I use one of these installed backwards just because I have several old blades laying around. I've never tried a 60 or 120 tooth plywood type blade nor have I used a new cross cut blade for this. Irwin makes a 48T metal cutting blade specific for this type of work that's around $50 if you're looking to buy a new one for your project. Have fun and be safe during your project...
Problem with using a carbide tipped framing blade is the teeth will break off, much better to use a fine tooth plywood blade or a blade made specifically for metal.
Definitely a safety glasses job. Even if you don't normally wear them. Even the tiniest speck of steel in your eye is not something you want to experience.
I'm wanting to cut some corrugated sheet metal into some 3in by 8 foot strips for some landscape edging, at least until i find enough rocks b the river to do 126 feet. but could you explain how this/ why this works? do i need a certain type of blade? hight or low tooth count? since its backwards does sharpness matter? most of mine are pretty dull already and i don't trust my ability to use tin snips to make a clean straight cut.
If you going to be doing that much cutting you may want to invest in a metal cutting blade. But for small jobs I use a 40 tooth Irwin carbide tipped crosscut blade installed backwards. The idea about being in backwards is that the blade is less aggressive, doesn’t tear up the work & acts like a metal cutting blade leaving a pretty smooth cut line👍
@@ClearCreekCabinMiniFarm would a extra fine tooth blade would better then? i got a few laying around but faily sure everrything badly needs sharpening
@@daltonlockyear7437 Never used a fine tooth blade. I’ve only used carbide tipped cross cut blades - My favorite for general purpose is the Irwin Marathon 40 tooth carbide crosscut👍
Thank you. I have to put a tin roof on my stable for a Mini-Horse we're getting next week. I wasn't looking forward to using tin snips, and now I don't have too. Question though? Wouldn't a metal cutting blade on the circular saw work?
It certainly will be a lot easier with the circular saw vs tin snips. Using the old crosscut saw blade backwards saves running to the hardware store & about $46 for a blade specific for the purpose - “Irwin” is my go to brand for circular saw blades & they make a 48 tooth 7-1/4” blade specifically for cutting metal… Best of luck with your project 👍
Why do you flip the blade around? I tried to cut a sheet (for the first time) the other day. LOTS of sparks, super noisy, and decided, it's not for me, and I need to find someone to do the job for me... Perhaps I'll give this a try. Thanks
You would only put the blade in backwards if using a crosscut saw blade for wood. This points the saw teeth backwards which makes the cut less aggressive. They make blades specifically designed for cutting metal but they too are very loud and throw out a lot of sparks. Safety Glasses and Hearing Protection are a must when doing this kind of work…
The only thing I thought of if I were doing this... is cutting from the back side to avoid marring the surface which seems fairly easy at times even with a good table on the saw. If that is too much figuring for certain cuts, then using that thin self stick painter's roll paper or lay a piece of newspaper across metal.
I would think not but it would depend on the number of teeth and the gauges that specific blade was designed to cut - I believe most roof panels at the big box stores are 29 gauge so you’d have to check your blade to the thickness of the metal you are cutting 👍
Thanks for the video. I just did eight sheets. I doubled them up and put them upside down. The first cut was good. The second cut was pretty good. The third cut was okay. The forth cut was "eh" Is this Diablo blade dead already with just four cuts.
Nice setup - I've never cut more than one piece at a time. I've always used a Marathon Carbide Tip Crosscut Blade installed backwards. (Marathon blades are a high quality blade) I've never used a Diablo?
@@ClearCreekCabinMiniFarm someone on one RUclips thread recommended cutting two at once. I cut the ridge cap by hand. I was going to try to use the circular and do it in two passes such that each pass that half is laying flat.
you will have to try this method to believe it, but it works. cut a notch at you desired length, then stand on the waste side and grip the sheet and rip it apart! It will be within a 1/4 " of square. My granddaugther was able to do it easily.
I’m about to build a small grill shelter. This exactly what I needed. My saw has the same edge distance between the edge and blade. Wonder if it’s standard. Thanks for sharing the info! Just saved me some money on air powered snips.
@@ClearCreekCabinMiniFarm thanks! Headed to buy the wood now. Never worked with metal roofing, but will definitely be wearing gloves and safety glasses!
Found this video few day ago... Today i try its...its works... Its help me alot..Thanks bro... But i wonder how many teeth perblade best to use...now i'm using 60t... Seem bit heavy...
Thanks for tuning in - I have always used an Irwin 40 tooth cross cut blade installed backwards (an old well used one kept for this purpose) Irwin does make a metal cutting blade specifically for this purpose for about $40 - Good luck with your project !

In H.S., I played drums in a local garage band and the amplifiers were right behind me and still have a set of drums in my "man cave" along with a 200 watt receiver and 8 speakers. Loud music, loud motorcycles, loud building and farm equipment such as chain saws, 6 yrs. in the Marines on .105 mm howitzers, and loud hunting firearms contributed to my hearing loss.

Thank you for the suggestion. Worked pretty well although some people may need to adjust the depth of their saw cut. Straight cuts are easier than diagonal. Do you have a trick suggestion for that? Saved me lots of time and impressed my Wife/Helper which is always a good thing. God Bless.
Glad you found it helpful - I can’t suggest any additional tips for cutting on a angle - one viewer said to turn the roofing upside down and cut from the backside - maybe that would help? 🙂
Are you talking about flipping a blade designed for cutting wood and using it on metal? I've tried that with variable results - it's much more effective to simply fit a blade for cutting metal. And I suspect it's safer too.
@@welshhomestead Yup, a regular old 40 tooth crosscut blade in backwards - A metal cutting blade is cleaner but if you’ve only got 1 or 2 cuts to do and don’t want to spend $40 on a metal one - an old crosscut blade backwards works well.👍
Never really cut sheet metal and corrugated at that ..... 2 cuts off a 3mtr length free hand all timber used for roof framing nothing left for last step completing roof off the side of shed for wood rack for turning. Turn blade on circular saw . . long timber or alloy straight edge will be square as.... 6:26 compared to free hand using knuckle to guide along ridge corrigation on the tin . Cheers i know what i will do next time cheers 👍😎😊
Wow - That will be fun - Maybe use a 12 foot 2"x4" as a guide - Screw it down on the waste piece side (if possible) and use the 2x4 as a rip fence guide? If that's not possible then maybe you could snap a chalk line and take your time with the saw blade depth really shallow - Best of luck but please be careful...
@@ClearCreekCabinMiniFarm it's just trimming off the overhang, but may still be a touchy situation. I'm probably going for the snap a line and take my time theory
@@vnyeu I always used an older (well used) carbide tipped Irwin crosscut blade for cutting 1 sheet at a time of corrugated meta roofing & never lost a tooth 🤔
Wish me luck, I'm going to attempt to cut off an addition off my trailer house, I'm just now starting"reasearch" into how to get it done.

Please be safe! Especially if you’ve never handled a circular saw before or if you’re working on a ladder - Don’t forget to work safely - Wear safety glasses, gloves, clamp down your work & get someone to help you if you’re not experienced doing something like this - Good Luck and please be careful!
Thanks for tuning in - The teeth on a normal crosscut circular saw blade can be too aggressive & can make too rough of a cut - This was a “Down n’ Dirty” quick way to cut roofing material w/o having to spend $40 for a good specialty blade😀 Been doing it this way for years & it works great - But always remember “Safety First” when using power tools👍
I would take it in small bites - Clamp down a guide rail the length you feel comfortable handling - Make your cut - Then move the guide and keep cutting - I've had years of experience with a circular saw but I couldn't do a perfect "Rip" that long... Best of luck...
As a retired general contractor, you should never cut with the paint side up as the hot pieces actually burn the paint and can cause premature rust, always cut from the back side.
@@sam-ww1wk True, safety glasses are necessary but I’ve cut metal panels for years this way - The saw-cut edges go up into ridge cap, so any minor rust is never exposed 👍
If you are planning on cutting more than one or two metal panels, you may want to purchase a metal cutting blade specifically designed for this purpose. (and you won't have to put one of those on backwards ) 😃- My favorite brand circular saw blade is IRWIN:

My options are to perhaps leave 1.5" sticking out over the edge, split the difference and have 3/4" sticking out and 3/4" X2 as a ridge vent, trim them, or skip the ridge vent and put in gable vents. There's a bonus room in the trusses, but I don't plan to insulate it, just the main area. I do have a diablo blade for my circular saw that I was planning on running to cut them... and having them stacked tightly and mask for overspray.
You, Sir, just made my week. I have about $3000 in used barn tin to cut, and I'm sure you know how much tin that is. I was NOT looking forward to doing it with tin snips or an angle grinder.
Wow - what are you building?
Use an angle grinder and invest in a good diamond blade. Cut through like butter.
@@michaelc5985 Good to know 👍
I started cutting steel siding in 1980 with a backwards blade in a skill saw. It always left burrs. If the blade heated up ypou could not cut a straight line. It won't cut wood if you turn it around. It will burn wood.
Buy a steel cutting saw from Dewalt with a 50 tooth ferrous metal blade. Also wear hearing protection and a Face shield. Hot metal coming off these saws can burn into your skin and stick to it.
@@tonysommerdyk9609 Thanks
gret video thank you. So basically I do not have to buy a metal saw blade just use my Wooden blade?? and turn it around as you said? the blade i have now only cuts wood? so by turning it the other way it cuts Metal too?? thank you Rachael from New Zealand
Be careful if you are using an inexpensive crosscut blade - I always use a high quality carbide blade that has been well used - cheaper blades can have the tips come off when doing this - And I don’t use the blade ever again for wood work - only for metal (in backwards) or dispose of it 👍
An excellent video! Just the thing I need for my current project.
Glad it will help you - Please be safe while completing your project - Thanks for tuning in 👍
Great vid … roofing a deck this weekend.
Does it matter what kind of blade you use in reverse. For example would a multi toothed blade be better than a framing blade?
Hey, good luck with your roofing project - I have always used a 40 tooth carbide tipped cross cut blade for general purpose framing and fast wood cutting (Irwin makes a good one) So I use one of these installed backwards just because I have several old blades laying around. I've never tried a 60 or 120 tooth plywood type blade nor have I used a new cross cut blade for this. Irwin makes a 48T metal cutting blade specific for this type of work that's around $50 if you're looking to buy a new one for your project. Have fun and be safe during your project...
Problem with using a carbide tipped framing blade is the teeth will break off, much better to use a fine tooth plywood blade or a blade made specifically for metal.
Definitely a safety glasses job. Even if you don't normally wear them. Even the tiniest speck of steel in your eye is not something you want to experience.
@@nonyadamnbusiness9887 Very true - great comment
I've cut roof sheets with a 60 tooth blade, without turning it backwards. Cut easy with smooth edges.
@@bryandickenson4845 Good Info - Thanks
Nice, Thanks
You’re welcome - be safe doing your project👍
To be clear, if you have a metal cutting blade you dont have to put it in backwards, correct?
Yes that’s correct - the crosscut blade in backwards is only if you don’t have a metal blade on hand 👍✅
I'm wanting to cut some corrugated sheet metal into some 3in by 8 foot strips for some landscape edging, at least until i find enough rocks b the river to do 126 feet. but could you explain how this/ why this works? do i need a certain type of blade? hight or low tooth count? since its backwards does sharpness matter? most of mine are pretty dull already and i don't trust my ability to use tin snips to make a clean straight cut.
If you going to be doing that much cutting you may want to invest in a metal cutting blade. But for small jobs I use a 40 tooth Irwin carbide tipped crosscut blade installed backwards. The idea about being in backwards is that the blade is less aggressive, doesn’t tear up the work & acts like a metal cutting blade leaving a pretty smooth cut line👍
@@ClearCreekCabinMiniFarm would a extra fine tooth blade would better then? i got a few laying around but faily sure everrything badly needs sharpening
@@daltonlockyear7437 Never used a fine tooth blade. I’ve only used carbide tipped cross cut blades - My favorite for general purpose is the Irwin Marathon 40 tooth carbide crosscut👍
Thank you.
I have to put a tin roof on my stable for a Mini-Horse we're getting next week. I wasn't looking forward to using tin snips, and now I don't have too.
Question though? Wouldn't a metal cutting blade on the circular saw work?
It certainly will be a lot easier with the circular saw vs tin snips. Using the old crosscut saw blade backwards saves running to the hardware store & about $46 for a blade specific for the purpose - “Irwin” is my go to brand for circular saw blades & they make a 48 tooth 7-1/4” blade specifically for cutting metal… Best of luck with your project 👍
Why do you flip the blade around? I tried to cut a sheet (for the first time) the other day. LOTS of sparks, super noisy, and decided, it's not for me, and I need to find someone to do the job for me... Perhaps I'll give this a try. Thanks
You would only put the blade in backwards if using a crosscut saw blade for wood. This points the saw teeth backwards which makes the cut less aggressive. They make blades specifically designed for cutting metal but they too are very loud and throw out a lot of sparks. Safety Glasses and Hearing Protection are a must when doing this kind of work…
The only thing I thought of if I were doing this... is cutting from the back side to avoid marring the surface which seems fairly easy at times even with a good table on the saw. If that is too much figuring for certain cuts, then using that thin self stick painter's roll paper or lay a piece of newspaper across metal.
@@micahthompson3762 great ideas 👍✅
Cool thank you for sharing
Glad you liked it
Many thanks!
You're welcome! - Good Luck with your project...👍
Thanks man!
You’re Welcome - Be careful out there 👍
Great tips. Cheers
Thanks for tuning in - Glad you liked it...👍
Good carpenter. handyman
Awh shucks - Thank you👍
The heat will damage the cut edges.
It will start to rust.
Heat damages the coatings on the steel sheet
Are you using a demo blade that cuts metal/nails?
Hi - No I’m using an Old Irwin Carbide Tipped Crosscut Blade installed backwards that I kept around for stuff like this🙂
We used to put a cutting disc in the circular saw, my boss would rather buy the discs than an angle grinder !
Whatever works....👍
Would it be easier to cut if the roofing was upside down? More flat surface area.
Probably - Several others mentioned it too - Learn something new every day👍
Good stuff, thanks! Even if your blade was a carbide blade designed for metal, would you still run it backwards?
I would think not but it would depend on the number of teeth and the gauges that specific blade was designed to cut - I believe most roof panels at the big box stores are 29 gauge so you’d have to check your blade to the thickness of the metal you are cutting 👍
What would happen if you didn't turn the blade around?
Would still cut but leave much rougher edges
@@ClearCreekCabinMiniFarm thanks
Thanks for the video. I just did eight sheets. I doubled them up and put them upside down. The first cut was good. The second cut was pretty good. The third cut was okay. The forth cut was "eh" Is this Diablo blade dead already with just four cuts.
Here's my setup I just used: drive.google.com/file/d/1e7VHxECCafxEJoS7HHMdMZfYW7Juogj5/view?usp=drive_link
Nice setup - I've never cut more than one piece at a time. I've always used a Marathon Carbide Tip Crosscut Blade installed backwards. (Marathon blades are a high quality blade) I've never used a Diablo?
@@ClearCreekCabinMiniFarm someone on one RUclips thread recommended cutting two at once. I cut the ridge cap by hand. I was going to try to use the circular and do it in two passes such that each pass that half is laying flat.
The Diablo (if I’m spelling it correctly) are at all the big home improvement stores (plus Amazon.)
@@raymondjiii Never tried that - good luck
you will have to try this method to believe it, but it works. cut a notch at you desired length, then stand on the waste side and grip the sheet and rip it apart! It will be within a 1/4 " of square. My granddaugther was able to do it easily.
@@dillon2107 Wow that’s amazing 😲 Thank you
I’m about to build a small grill shelter. This exactly what I needed. My saw has the same edge distance between the edge and blade. Wonder if it’s standard. Thanks for sharing the info! Just saved me some money on air powered snips.
Glad this is gonna help - Best of luck with your grill shelter - Be safe working on your project!👍
@@ClearCreekCabinMiniFarm thanks! Headed to buy the wood now. Never worked with metal roofing, but will definitely be wearing gloves and safety glasses!
@@ScruffyCityFishing Have fun - BTW I prefer the “self piercing” roofing screws over the “self drilling” ones !
@@ClearCreekCabinMiniFarm oh, great info! Building it to move my grills and make room for.. more fishing stuff haha.
Found this video few day ago... Today i try its...its works... Its help me alot..Thanks bro... But i wonder how many teeth perblade best to use...now i'm using 60t... Seem bit heavy...
Thanks for tuning in - I have always used an Irwin 40 tooth cross cut blade installed backwards (an old well used one kept for this purpose) Irwin does make a metal cutting blade specifically for this purpose for about $40 - Good luck with your project !
@@ClearCreekCabinMiniFarm he he im using bosch blade..that 60t...lost the carbide. but its doesnt matter..i got lot of that kind of blade.. hahaha ...may its because the quality ... then im using 40t.. seem much better even in same brand
For metal I believe it's the more teeth the merrier. @@ClearCreekCabinMiniFarm
I would have cut from the back side so ridges would be on the bottom , have a 4.5” metal blade ?
You know that’s a great tip 👍 - Thank you for your input.
One thing you failed to mention (or I missed it) is ear protection. Cutting metal roofing in this manner is VERY LOUD!
Yep, you should really wear hearing protection too. Being a kid from the 60’s, I already blew out my ear drums from Led Zeppelin 😂😂
@@ClearCreekCabinMiniFarm Just from Led Zeppelin? I am 73 and live in the country. In H.S., I played drums in a local garage band and the amplifiers were right behind me and still have a set of drums in my "man cave" along with a 200 watt receiver and 8 speakers. Loud music, loud motorcycles, loud building and farm equipment such as chain saws, 6 yrs. in the Marines on .105 mm howitzers, and loud hunting firearms contributed to my hearing loss.
@@reb1050 wow - so much alike - I too was a drummer in a rock band in the late 60’s for about 3 years - The Marshall Amps & PA were set up right next to me - Left ear is the worst - where the bass players guitar was plugged in🙃 Thanks for your service✅
Thank you for the suggestion. Worked pretty well although some people may need to adjust the depth of their saw cut. Straight cuts are easier than diagonal. Do you have a trick suggestion for that? Saved me lots of time and impressed my Wife/Helper which is always a good thing. God Bless.
Glad you found it helpful - I can’t suggest any additional tips for cutting on a angle - one viewer said to turn the roofing upside down and cut from the backside - maybe that would help? 🙂
Are you talking about flipping a blade designed for cutting wood and using it on metal? I've tried that with variable results - it's much more effective to simply fit a blade for cutting metal. And I suspect it's safer too.
@@welshhomestead Yup, a regular old 40 tooth crosscut blade in backwards - A metal cutting blade is cleaner but if you’ve only got 1 or 2 cuts to do and don’t want to spend $40 on a metal one - an old crosscut blade backwards works well.👍
Great system.
Glad you liked it - Good luck w/ your project
Never really cut sheet metal and corrugated at that ..... 2 cuts off a 3mtr length free hand all timber used for roof framing nothing left for last step completing roof off the side of shed for wood rack for turning. Turn blade on circular saw . . long timber or alloy straight edge will be square as.... 6:26 compared to free hand using knuckle to guide along ridge corrigation on the tin . Cheers i know what i will do next time cheers 👍😎😊
Great - glad it will help the next time you cut roofing...👍
Hearing protection also!!
Yes that is a good idea. I'm a product of the 60's playing in a rock band so my hearing is already shot 😲
Unfortunately I need to do a 12 foot rip cut on the final piece of my shed roof. How would you go about it when the metal is already installed?
Wow - That will be fun - Maybe use a 12 foot 2"x4" as a guide - Screw it down on the waste piece side (if possible) and use the 2x4 as a rip fence guide? If that's not possible then maybe you could snap a chalk line and take your time with the saw blade depth really shallow - Best of luck but please be careful...
@@ClearCreekCabinMiniFarm it's just trimming off the overhang, but may still be a touchy situation. I'm probably going for the snap a line and take my time theory
I use wood blade and change it backwards. After cut 3cm easily. But I stop and check the blade. Find out 3 pieces of teeth missing after do this
@@vnyeu I always used an older (well used) carbide tipped Irwin crosscut blade for cutting 1 sheet at a time of corrugated meta roofing & never lost a tooth 🤔
Wish me luck, I'm going to attempt to cut off an addition off my trailer house, I'm just now starting"reasearch" into how to get it done. I'm 50+ years old crippled up broad, no money to pay to have it done, but by God Almighty, im gonna git r done! First video I've watched, since I have to start at the roof!! 😁 wish me luck!!
Please be safe! Especially if you’ve never handled a circular saw before or if you’re working on a ladder - Don’t forget to work safely - Wear safety glasses, gloves, clamp down your work & get someone to help you if you’re not experienced doing something like this - Good Luck and please be careful!
@@ClearCreekCabinMiniFarm that was so sweet!! Thanks, and you bet, safety first seriously. Good video
Why the saw blade backwards? Does it not cut a clean line otherwise? What happens if u don’t put on backwards?
Thanks for tuning in - The teeth on a normal crosscut circular saw blade can be too aggressive & can make too rough of a cut - This was a “Down n’ Dirty” quick way to cut roofing material w/o having to spend $40 for a good specialty blade😀 Been doing it this way for years & it works great - But always remember “Safety First” when using power tools👍
So coukd you use a old blade since youre not using the teeth?
Yes - I recommend you use an old blade, so you don't dull a new one.
I need to split a piece of tin in half the long way lol. Not sure if I feel like setting up a jig for a 20' piece of tin.
I would take it in small bites - Clamp down a guide rail the length you feel comfortable handling - Make your cut - Then move the guide and keep cutting - I've had years of experience with a circular saw but I couldn't do a perfect "Rip" that long... Best of luck...
As a retired general contractor, you should never cut with the paint side up as the hot pieces actually burn the paint and can cause premature rust, always cut from the back side.
@@mkrug1149 👍
You’re gonna get shit in your eyes with only glasses and a backwards blade is for plastic, not metal
@@sam-ww1wk True, safety glasses are necessary but I’ve cut metal panels for years this way - The saw-cut edges go up into ridge cap, so any minor rust is never exposed 👍
Young Man to shy to show face. Thanks for the lesson.
That’s funny - sometimes you cut off your head when setting up the camera multiple times while making videos 😂 - Hope your project turns out well 👍
thank you
You're welcome - Please be safe when using power tools...
My dad taught me to do this in 1965. But he did not suggest ear protection, which I most certainly do . The noise is nasty.
It’s pretty loud that’s for sure. If that didn’t wreck your hearing, the Rock Music from the late 60’s certainly did. Thanks for tuning in…
I read the specks that fly off ,burn into the metal and those spots will rust later.
Sure - blow off or brush off any metal specs - I’ve cut painted metal & galvanized roofing for years & have yet to have had a problem 👍
I cut the same way for aluminum
Good to know - Thank you ✅
Not the only thing to use a saw blade backwards for, vinyl siding,...
