Hello Mister Gal Volunteer. I'm glad you enjoyed my video, thank you for your comment. Take Care Jim.
another very good video. thank you. I so very much agree with you with not just being able to do something but actually to be able to do it WELL.
Hello Joe. Thank you for your comment. It is a nice feeling when you look at the line, you look at the hacksaw blade then get the blade to follow the line. All it needs is a little practice. Take care Jim
Another great video Jim.
Hello Dennis
Glad you enjoyed the video. Thank you for your comment.
Jim
Thank you for sharing. Great video! Easy to follow and helped me cut my first piece of metal 🎉
Hello Sephanie. Thank you for your comment. Its nice to know I have brought you together with your first hacksaw. Never seen myself as a matchmaker before!
Wonderful! Thank you!
Hello, I'm glad you enjoyed the video. Thank you for your comment. Take Care Jim.
Thank you sir, I learned some good techniques from you!
Hello Christopher.
I'm glad you found the video interesting, and thank you for sending in your comment. The hacksaw is one of the tools most taken for granted in the workshop, most people assume they can use it, but most people cannot use it well! When I started my apprenticeship in 1971 my first three days were spent with my hacksaw cutting large pieces of metal into smaller pieces, but I had to do it properly! Take Care Jim
What a brilliant instructional, thank you!
And Thank you Deeno for the comment. I’m so glad you liked the video. Take care Jim
@@CYC123 me too. Thank you
Thanks! I didn't know i was supposed to loosen the blade when not in use.
Hello Jeremy. Thank you for your comment. During my apprenticeship I was told to loosen the blade at the end of the day, when I asked why, I was told: It lets the blade and frame rest, it also means when you pick it up the next time you need to use it, you can make sure you place the correct tension on the blade before you start your cut. Over the years I have met a lot of people who never loosen their hacksaw blade, have I ever seen a problem caused by leaving the tension on the blade? Well yes, but only the once, it was an Eclipse hacksaw with a diecast aluminium handle, and a stem that held the blade. Over the years the cast aluminium stem from the handle had moved, it had slowly bent under the years of pulling tension on the blade. I feel loosening the blade once you have finished using the saw is the right thing to do for the reasons I spoke about above. Enjoy your workshop, Take Care Jim
Just what I needed. Thanks
Hello Dan. Sorry, I had missed some comments, this was one of them. Thank you for your comment, how is your hacksawing now, it takes a little practice. Take Care Jim
@@CYC123 I've been hacksawing for years and didn't realise you could steer the blade like that. Obvious in retrospect, but only once someone's told you. I usually just solved the bad cuts with a file. Much much easier now
@@danblackwell3586 Hello again Dan. It warms my heart when I receive comments like yours. I’m so glad you found my video useful, It’s why I make them. A lot of time people will pick up a tool and use it because they think its operation it’s obvious, a hacksaw is one of those tools, it’s not until you think about how it works that you can use it to it’s full potential. I hope your sawing in the future goes where you want it to. Take Care Jim.
excellent instructions 👍
Hello Andy
I have just sent a reply to your last comment and what do you know, I have found another! Thank you for spending time looking at my videos, I hope you do find them interesting and useful. Take Care Jim
Thank you so much!! I've been messing this up in every possible way for years, but not anymore ...
Hello, I’m so glad you found this video useful, thank you for your comment. Take Care Jim
Brilliant explanation, very clear and helpful. My hacksaw technique has improved leaps and bounds. Even cutting nearly straight lines!! Thank you.
Hello Tony. Thank you for your comment, I’m so glad you found my video helpful. All it takes is a little bit of practice, and all your cuts will go where you want them to. Take Care Jim
And taking the time to reply - good on you Jim, there are not many like you around these days - sadly 👍👍
Hello Tony, thank you for your kind words. Take Care Jim
I thank God for people like you. Thank you so much for taking the time to make this video and for sharing your expert knowledge with others. This is how the internet was meant to be used - for the benefit of humankind. God bless you! Got to go saw some conduit now.
Hello Hottiepants87. Thank you for your comment and kind words. How did you get on with your conduit?
Take Care Jim
Hi Jim, wow I can’t believe you took the time to read my comment and even reply. The conduit cutting went fantastic. I couldn’t put it in a vise because it was 115 inch long, but I was able to put it on a bench and then use my foot to hold it in place. Not as convenient as your set up, but I stayed on the line extremely well and got the job done quickly. There were 3 of them and the third was the best because I was building the skill.
Well done with your sawing, the more you do the easier it becomes. When I started my apprenticeship (1971) the first lesson my group had was in the "Metal Fitting Shop" I had my own hacksaw my Dad had bought me, funny enough its the old one you see in the video, 50 years old now and still going strong! We spent three days sawing, sawing, sawing, I cut sheets of metal into strips, 90degree angle iron into hundreds of "L" shaped pieces all 1/8" of an inch wide, and bars of steel into coins. I remember being a little jealous of the apprentices who went into the the turning shop first, I had always wanted to get my hands on a lathe! Any way, I have started to ramble.
Take Care Hottiepants87 and have fun with your hand tools, Jim
That sounds like a great apprenticeship! Very wise to develop the skill through repetition. It’s interesting you mention lathes because I am utterly fascinated with them. There’s something about the process that’s completely intriguing. I even thought about getting a lathe and making my own bowls, but decided against it when I discovered you can’t soak them/use them for soups or hot liquids (which kind of defeats the purpose). Take care as well.
You could always make wooden bowls for your ceramic or stainless steel bowls to fit inside.
Best of both worlds!
Take Care Jim
THANK YOU

Thank you for the video! I've struggled to cut some thin steel C-frames today, it was difficult to get the saw to run smoothly. After watching your video I think the next round will you much better. I'll be sure to clamp it more securely and it looks like I wasn't holding my saw at the right angle. I'm looking forward to trying again!
I'll tell you what, "945536436" your name is a bit of a mouthful!
Thank you for the comment, I hope you have a better day at cutting the C-frame. Some time ago I had to cut some lengths of C-frame, it was about 2-inch square (50mm) and both sides bent back on their selves on the open side to make the frame more rigid. The best way I found to cut this section was to place it in a vice with the solid rear side up, I cut across it at a shallow angle not allowing the blade to cut down the sides very much. I then turned the job in the vice so one side was up and continued the cut from the back across this side at a shallow angle, I then turned it in the vice again and cut the second side the same. I think the secret here is to only cut one side at a time, and don't cut at 90 degrees to the surface only at a shallow angle. Hope this helps. Take Care Jim
Ahh,, I remember when hacksaws looked like that,, it's great you're using an antique for this demonstration,, 🤣
Hello John. Thank you for your comment. It’s a funny thing, my Dad bought me that hacksaw brand new as I started my apprenticeship in 1971. I don’t see it as an antique, it’s just my old hacksaw, and still the first one I pickup when there is sawing to be done.
Hello, Sir I am from ATMI Surakarta. Thanks for your information, Sir. I think your video very useful to all people.
Hello Ariq Sukma Novantino. Thank you for your comment, I am so glad you found my video useful. I see you live in Java, that is almost on the other side of the world from where I am in the UK. The Internet has made the world a small place. Take Care Jim
I see that it has been mentioned but "hacksawing is a simple thing unless you want to do it well" made me chuckle. Good to know that I'm not the only one after all these years that still needs practice with technique... I think that the workpiece height is so important in relationship to a vise and a bench and a person's build. Would like to see you do a video on your vise, alone. Thanks a lot for this.
Hello, and thank you for your comment.
My big red vice was not so red when I first met it. We have to go back 40 years. A mate of mine, Bazz, had been in contact with me, his grandfather had gone to meet his maker leaving his house to be cleared. The old boy had been living on his own for the best part of 20 years. The small workshop attached to the back of the house had spread into the house, tools and material were every where. The Grandfather was an engineer who worked for London Transport, he use to service and maintain the old Route master red London busses. The vice we found under his work bench, its condition was almost new although I think it was quite old even then. Bazz had a vice in his workshop so I could have this one. I was so pleased. Luckily my work benches are heavy and strong, so once the vice was stripped cleaned and rebuilt, I fitted it to the bench. Its a little on the large size but its lovely, I have know this vice longer than my wife and have probably spent more time with it as well. Take Care, and carry on making your videos. Jim
@@CYC123 God bless you, Jim. Thanks for the information on the vise... It's a great story. I look forward to more of your content as I am always learning. I think when you stop learning, stop trying, stop challenging yourself, you might as well cash in your chips. Also, not taking one self too seriously helps!
Thank you for the wisdom, Sir. May I ask what are your thoughts on lubricating the blade and job with oil when cutting?
Hello Elijah
Thank you for your comment.
Now to your question “What are my thoughts on lubricating a hacksaw blade while making a cut.”
The first thing we need to think about here is what does a lubricant do?
Well, a lubricant is slippery and because of that it will reduce the friction between things that are rubbing together. If there is less friction less heat will be generated.
Another quality of many lubricants is they are sticky to fine particles,
Let’s assume we have a new hacksaw blade in the saw.
Held in the vice there is a piece of 3mm thick steel plate which we need to cut a strip off its end.
The blade will be cutting straight down into the metal, its cutting across the 3mm of steel only.
Let’s see what will happen if we start this cut with no lubricant.
The teeth of the blade due to their “SET” are cutting a slot that is wider than the main body of the hacksaw blade, because of this, the back of the blade should not rub hard against the edge of the metal being cut so little or no friction will occur between them. This should be an easy cut.
But let’s try with some oil which we wipe on the blade and gloop into the cut that is already there.
We continue with the sawing, it feels about the same as it did before but the fine metal filings generated by the teeth of the blade are now sticking to the oil and making things messy.
In this configuration I can’t see much of an advantage in using a lubricant.
Now change the material from 3mm thick steel to 3mm soft aluminium.
We cut in the same way as we did with the steel with no lubrication.
Sometimes with some aluminium, pieces of the cut metal will stick in the teeth of the blade which you need to clean out every now and then. If you find yourself in this situation, then try a lubricant on the teeth of the blade, it may help prevent the pieces sticking to its teeth.
The sorts of lubricants you could try is oil but as I said above that can be messy, other things you can try is rubbing chalk or graphite on the blade teeth this may allow the cuttings to fall away from the teeth easier.
Really, it’s knowing what lubricants you can use then give them a go when you have a problem, see what is best for the material you are cutting.
If you try cutting a lump of rubber with a hacksaw you may find that quite challenging, the rubber will not cut as well as a hard metal, the cut left by the teeth won’t be as wide as it was in metal so more friction will be generated, in some cases it will almost lock onto the blade. If you find yourself hacksawing rubber use water as the lubricant, possibly with a little soap in it.
The bottom line is this, if a lubricant helps in some way to make the job easier it’s got to be the thing to do. Give them a go see what you find.
I hope this helps. Take Care Jim
Thanks for the video....just started an apprenticeship and struggling with this. Cuts keep going off to the left of my scribed line but whatever way i seem to angle the blade it just seems to carry on to the left...ill try these tips tomorow though
Hello DH-TV. Thank you for your comment. Good luck with your apprenticeship.
The hacksaw is an important tool to master, everyone expects it to be easy, but to use this tool well and to get it to cut where you want it to cut will take a little time, and more practice than you may expect. Something I didn't mention on the video is to make sure the frame of your hacksaw is not twisted, look along the length of the blade once you have the correct tension, the blade needs to be straight and flat, it must not twist between its ends. If the blade is twisted either the blade is not seated correctly on the pins that hold it, or the hacksaw frame is twisted, in either case you will have trouble keeping your cut straight if the blade is twisted.
Remember there are two ways to "steer" the cut of your hacksaw blade, you must use the correct method and that depends on the angle at which you are cutting the job. If you are cutting straight down at 90° to the face of the job, you steer the blade by twisting the frame the opposite way you want the saw to cut. If you are cutting down on your job at an angle, then you steer the blade by biasing the hacksaw handle either left to cut left or right if you need it to cut right.
Look at the video again, these are the two techniques I show there.
Good luck DH-TV, please let me know how you get on. Take Care Jim
@CYC123 thanks and thanks for the detailed reply. Yes, obviously being inexperienced it's difficult to sometimes assess what is down to my own (poor) beginners technique and what is being affected by old, well worn tools in the college. Certainly a knack to it. I'm tending to veer to the left, so to counter that I'm starting outside my lines and cutting to the left which means I'm not going over my lines BUT I'm then left with a large section that needs filing down. But I'll get there! And thanks again
Now I'm off to see you've made a video of how to mark and cut thin wall tube straight and square
Hello 750Triton. I hope you enjoyed the videos, thank your for your comment. Take Care Jim
Can a metal pole be cut at the floor half inch if it's bearing weight???
Hello Victoria. The answer to your question is "It depends". Yes you can cut a metal pole close to the floor as long as there is enough space to move the hacksaw and if the pole is not supporting any weight. If it does have weight bearing down you will be able to start your cut then as the pole weakens because of your cut the gap will close and clamp your blade, that's not good news. To cut a vertical pole with weight on top of it, you will need to either remove the weight, or support it some how as you make your cut. I hope that answers your question?
Do you apply pressure going backwards?
Hello Fan. Your question: Do you apply pressure on the back stroke when using a hacksaw?
I assume your referring to down ward pressure pushing the teeth of the hacksaw into the job.
Because of the shape of the hacksaw blades teeth, they will cut most efficiently on the forward stroke.
As you pull backwards some swarf within the blade teeth will clear giving the appearance the blade is cutting.
I release MOST of the downward pressure on the back stroke of the blade, I do this for two reasons: The first, I think it prevents wear to the tips of the teeth. Second, a little downward pressure on the blade as as you pull it backwards will prevent any bounce of the blade, bounce is bad as it may damage blade teeth on the job.
I hope this answers your question. Take Care Jim
