I just tested this with a Hydraulic Press VIDEO: ruclips.net/video/q3DsOm7tsjg/видео.html
LOL, Moe - I was just about to post a question asking whether this would work in my 20 ton press! Time to click on your link to see the answer to my question! ;-)
I'm 80 years old and I learn something new from this guy in each of his videos...Thanks for all.
As my late Dad told me your never 2 old to learn something new.
Yeah but where does this guy comeup with this stuff? Is he an engineering genius?
@@patriciahibbert6139 Thanks Patricia...I agree with your late Dads advised.
Thanks guys, I'm glad you liked it.
Happy birthday
Well you finally answered the question: "How do you put a square peg in a round hole?" You sharpen it and heat treat it, then hammer away! Great job! Thanks for the information!
Thank you for the excellent tip! I don’t know how many times I have wanted to make square holes, you made it look easy!
When you heat the tip of the rebar, watch the color move down the metal towards the tip, and as soon as purple hits the tip quinch it in oil and swirl it till it cools off. I've made cutting chisels this way in high school and we had to cut thru 1/2" bolts without damaging the cutting edge to pass the course. I still have and use my chisels I made 20 years ago
Yes !! I rembr -- but l always wondered why purple and not pink, straw color, grey ? Purple's it huh ?
Good tip and thanks~!!
Good video!Been working with metal most of my life, and did not know that rebar would harden.Gives me a good source for steel that can be machined and then hardened.
“Just the tip” that worked about half the time in high school!
Heck yeah
Awesome trick!
One tip on heat treating…..it’s the correct temp to quench when salt will melt as you are heating it. Learned that from forged in fire! 👍
I once used a small broken 3 corner file & ground it to fit in my sabre saw, worked great as well...
This is a great video. I didn't know whether you could do anything beyond case hardening of rebar but it looks like it's good enough steel that you can actually make decent hardened tools out of it. Like you said in the one part, annealing it will retain much of the hardness and take away the brittleness from the initial hardening. I learned how to do this from Tubalcain and fixed my old Brazilian-made single shot youth shotgun I bought when I was 14. There was a spring-loaded pin in the forearm that had bent because the metal was too soft and the forearm wouldn't stay on when breaking the breach. I initially fixed it by running some electrical tape around it and it stayed fine that way but it always bothered me that the tape was there. After learning how to harden steel parts, I pulled it apart, took the spring off and straightened the pin. I hardened it with water quenching, then I heated it back up hot enough that water would bead off of it and let it cool slowly. Once everything was cooled off, I reassembled with some light oil on the forearm and it works as it was originally designed. Stays put when breaking the breach and comes off when it's closed and you give it a good yank. The manufacturer probably cut a corner on that run and skipped the hardening process on that pin, so hardening that pin fixed it. I was so stoked when it worked. Haven't shot that thing since I was a teenager but it was neat to get it working the right way. Now when I pass that shotgun on to one of my boys they'll never know the difference.
About 8 months back I did a video about hammer broaching with HSS on a piece of aluminum. Recently tried it again. But this is a great idea. I had no idea rebar could be used like this. Best thing about yours, is you could also taper your tool to make for some adjustment
THANK YOU. been looking for a simple solution like this. I have to put carage bolts into a 4x4 1/4 wall square tube but only on one side and NO OTHER than a file would do it and this is going to save me a day of filing!
Yes, I have been playing with rebar for years. if you have trouble resharpening it, heat it back up and allow it to air cool. This will make it soft again. Great video btw.
Great alternative to a square punch.
I love the outro. I know that place and have driven by it thousands of times..
I’ve been subscribed for a while now. I originally found your channel when I was looking for videos on my first car, a ‘95 Ford Escort. I subscribed because I thought you’d have more videos on Escorts, but I’ve stayed because you have way more to offer. I really enjoy your videos, no matter the content. Keep it up!
That's awesome. The Ford Escort is still kicking along at 320k miles. It never breaks so I rarely need to do any videos on it.
Always amazed at how much you know! I always learn something new from your videos
Thanks Man.
never seize to amaze me what you can do with simple stuffs !
That's a good point. I should have used some lubricant as it will help keep the cutting edge on the tool sharper, longer.
This is the Second video of yours I watched. AGAIN, I’ve learned some new skills! Thank you for sharing!!
Hey Thanks, I'm glad you liked it.
I have always filed them, going to try this. Thanks
That’s a great idea love from oxford England 🏴
This will prove to be very useful in the shop. Thank you for sharing.
Thanks, I'm glad you like it.
Ive seen those made in a stepped configuration before but i like your head setup.
That looks like a good idea. I've always drill a hole and used a file to make a square hole. Your way is much faster.
When I need to make a row of 5-6 of these holes in sheet metal this beats filing for sure.
Same here. Drill and file. But I’m not very often worried about square holes.
I’ll have to try this sometime.
Great idea! Trivia- rebar is measured in 1/8 inch increments. Number 5 = 5/8 inch. Most rebar is schedule 40 with 60 and up higher grade.
Nice job! Re-rod is useful, no doubt. I have saved some big bucks making actuating rods for Cub Cadet tractors and others, by using my woodstove as a forge. One problems that I have run into- repeated heating does cause the metal to go swiss cheesy and become very brittle and crumble away. They are made from recycled steels and are full of inclusions and stuff anyway.
It's a great resource for cheap steel.
Great video and sweet idea. The hardening process from what I have seen, was heating the metal until it is no longer magnetic. Quench in you choice water / oil, but they anneal the metal to soften it to be less brittle. So blue is next color during annealing, then air cooled or quenched. It’s been a while since I have watched a black Smith or knife maker, but worth looking into to avoid having more work to sharpen. Retired auto tech, but I still fabricating. With the price of weld shield gas, oxygen & acetylene has gone triple from invoices of 10 years ago, makes it difficult to justify a purchase. Great lighting, volume and camera angles are great. Having a tripod makes a huge difference. I hate the “One-banded” videos and they try to open the worlds toughest plastic parts box.
I have thought many times, if they made cars out of certain plastics used in packages they would last forever! Thanks! I will not forget this when a future project would be better with a carriage head bolt. They have a valid place in the world. I thank Black Smiths from 150-200 years ago who formed these for “Round Top Trucks” and wagons plus stage coaches!
That's a very good idea, I would have never thought rebar could do what a Machinists broach would be able to do. Learned something new this morning.
Thanks, I'm glad you liked it.
this guy is amazing!!!! he is like the guy fiery of the maker trade
Thanks for this video. Im a home hobby welder as well as retired. I'm pretty sure I will be making one of these broche's very soon
Thanks, I'm glad you like it.
Really useful lesson. Thanks and keep up the good work!
Buddy, you have the idea's and DIY all figured out. Between you and Pawpaw, I get all the good stuff
Thanks, I'm glad you liked it.
Nice broach, Dude! Necessity is the mother of invention!
It really is. Thanks Martin. -Moe.
You come up with some really good tips. Thanks.
Thanks, I'm glad you liked it. I'm just playing around in the shop.
Love this kind of ingenuity. Good job and Thanks!!!
Glad you like it. Thanks.
Wow neat. I'm going to through away all my square drill bits. Thanks
Ha...
Just put this in a drill and make a round hole
Wow you're channel blue up. I've been here for a while and I haven't noticed your subs in a long time. You deserve it. Always quality content
Thanks Dustin. I'm just having fun in the garage.
*blew just saying lol
Awesome. Always excited when I see you upped a new video.
Hey Thanks, I'm glad you liked it.
Really good solution. Thanks.
I need to get a propane torch now.
Excellent educational video !
Not that I'm going to do it.
But add another trick under my sleeve just in case when duty calls.
Thank you! The solution to my Carriage Bolt problem. Much appreciated.
Thanks, I'm glad you liked it.
Cool thanx for the video, that will help me forever now.
It's great to pass on the passion of knowledge.
Hey Thanks, I'm glad you liked it.
Great explanation on how to make a square hole . I'm going out to the shop to make a new tool!
Thanks, I'm glad you liked it. It was a fun project.
I will definitely do this with aluminum or wood materials. Carriage bolts do look better on many projects. Not sure it’s worth the effort to punch 24 holes in steel, but the softer aluminum & wood materials--definitely worth the effort.
Kool! I drill a round hole then use an air filer to make it a square for carriage bolts. Super easy with the air filer from HF!
That works.
That's terrific. I'm trying to mount a wheel chair motor on a bike, this will help.
ANOTHER excellent, but as usual, USEFUL video. Thanks!
Hey Thanks, I'm glad you liked it.
Awesome tip, Moe. You have more good ideas than any two guys I know.
Thanks George.
Nice! That is quite effective. Love that 🐕
Hey Thanks, I'm glad you liked it.
Since only the corners of the broach are doing the cutting, think about how you could make the tip of it round to fit into the hole and just have the corner a bit higher up and come in contact as the broach moves into the workpiece. Just a thought.
i wouldn't have believed it if i didn't see it. now i have to try it.
I'm a professional machinist and I have made broaches at work and at home but I have always made them from high-speed steel, I would never have guessed that rebar would harden well. Knowing that could be very useful for a lot more than broaches.
It's not the most predictable material to work with, though it does harden nicely. Depending on the grading/rating it can have higher carbon content and get too brittle with the standard heat to orange and quench method. The 1/2" bar I used needed as much help as possible and I used water vs oil quench to achieve they hardest steel possible. The 5/8" bar would have been better a little softer and an oil quench would have achieved this better. You can always anneal it at any time though.
Excellent, thank you again.
Definitely a handy guy to have as a neighbor...and of course the pooch too
Hey Thanks.
Like always another awesome video and I always love your dog shots.
Thank you very much!
Really interesting. Another thing i learn today. Thanks!!! greetings from Spain :)
Awesome, I'm glad you liked it.
i always just filed holes square with a three sided file. this looks easier, well, faster at least.
I’m an old guy largely new to serious metal working and heard from “expert” sources that rebar could not be hardened. I trust results and you have demonstrated a contrary opinion that deserves respect, imo. Going forward, I will assume that the carbon content of rebar varies wildly and that not all rebar can be dependably hardened. Right?
Great teaching. You rock!
Hey that is a great way everybody has some rebar lying around
Last few seconds of the video where the best 👍🏼
Thanks, I'm glad you like it.
good presentation, no bs, well done
Good idea. (Fixing plow mounting?)
I, similarly, made a 1/8" wood chisel.
Thanks, I'm glad you like it.
New subscriber to the channel. Great stuff. Love the dog, I have a blue heeler myself. I ran across you video on tire changing and have been watching since.
Awesome. I'm glad you liked it. Heelers are great dogs.
Very impressed, thanks for the video.
Awesome. I'm glad you liked it.
Now THAT is handy to know! Thanks, JD
Thanks JD. -Moe
Kind of a cool trick. Especially the hardening part.
A square file can work, but it is a lot of work.
When I have to make just a few square holes out of round ones? I use my little cordless Milwaukie mini sawzall (called a Hackzall) with a fine tooth metal cutting blade that resembles a narrow jigsaw blade (but has the sawzall blade mount shank on it..). It cuts on the pull strokes, of course, while the tool foot is held tightly to the work, and files out the square corners real quick.
That's how I do square holes in wood.
I love new skills , thank you
Thanks, I'm glad you liked it.
Did not know rebar could be hardened enough to broach more than cardboard! Have to try hardening some of my homemade rebar punches and other hackery tools now.
What a educational video Moe! Thank you.
Thanks, I'm glad you liked it. It was a fun project.
And another great video, thanks for sharing 😊👍👍
Hey Thanks, I'm glad you liked it.
Interesting, I didn't know rebar could be harden, good video.
Very creative , thanks !
Thanks for watching!
The surprising bit, for me, was that you can harden rebar - got to try it myself :-)
Hey Thanks, I'm glad you liked it.
Same here. Never occurred to me.
Me too.. i know they make knives from rebar, but i was always told they are not good knives because there isn't enough carbon to harden... guess this proves them wrong
Great idea Moe! I wonder if repurposing an old air chisel bit and using the air hammer would work to make square holes? Love the rebar idea !
Fantastic idea. I could put a simple cup on the end of a bit to hold the rebar rod.
Another good one !!!...Thank You !
You made a broach. Nice job!!
Thanks, I'm glad you like it.
Holy crap that was a cool idea. Good advice to keep the tip hard and sharp. 😁
Hey Thanks, I'm glad you liked it.
Thanks great build. TANK
Awesome, I'm glad you liked it.
65 thanks 4 another bad ass video. Keep ON
Hey Thanks Man.
Good job, I use a shop press to punch through.
Hell Yeah!!! Great metal working Hack !
That is slick man,thankyou
Thanks, I'm glad you like it.
To find the diameter needed I times the size I need by 1.414. So to make a 1/2 square you would need a 7.070 round bar. (.5x1.414= 7.070) you may be able to find this from a coil spring or torsion bar. Great video. Thanks for sharing.
Thanks for the info!
If after a few. Taps you put it back in the drill press it will make removing the rest easier especially with thicker stock
Great idea/work aid.... The only thing I might suggest is when you are about half way through (or as often as needed) is to redrill the hole to help clear out the metal that is gathering in the center. This will help by decreasing the amount of metal you have to broach out as it builds up...... Just a suggestion to a great idea. Keep up the good work..
That's actually a fantastic idea. Thanks for the great input.
Thanks for sharing
Super cool! Thanks.
Thanks, It was a neat project.
Great Stuff Brother ! ! !
Appreciate it!
Good stuff Moe. Now I just need to learn how to fix and build stuff so I can use all the cool stuff you teach me. LOL
Thanks for watching. That's step one.
Awesome! I'm gonna try this!
Thanks, I'm glad you like it.
Thx! I just learned something.
Thanks. I'm glad you liked it.
Great idea
Thanks, I'm glad you liked it.
You made a Great home made tool....carriage bolts are cheap to buy per pound at the farm store and The bolts are good to use on like making home made stoves and stuff
Hey Thanks.
Great video and tip, thank you!
Hey Thanks. It's a fun little trick.
Wow, I never wondered how to do that. Just assumed I'd have to file it out. Another super cool trick. Thanks again Man :). One day you'll be making your own DYI water jet, lol.
Water jet... Here I come.... That would be a fun tool.
Very Impressive!
Impressive tip! Thanks
Awesome. I'm glad you liked it.
You know I am going to do this. Great for snowblower carriage bolts
That's exactly what I use it for. Seams like the scrapper bar is always so far gone I have to rebuild it.
Nice! Thanks! 🙏🏼
Very nice 👍
