My tip on screw thread recovery: Before cutting to the desired size, thread a nut to the screw head. Make the desired cut. Then unscrew the nut and it will take care of recovering the thread.
I was about to suggest that, I saw that trick in a woodworking magazine a while back, works perfect everytime I do it, I use it a few times to secure a router plate I made and the screws were too long . I bought a whole bunch of them I shorten them every time I need a new plate
Great tip, thanks fellas!
Tip: most metal is dirty because at the mill they put a greasy coating to prevent rust. So remove the coating only if you are going to paint/work the area soon and not just for the shake of cleaness. Great video for beginners!
Great point! Thanks Joe!
Great video, thanks David! I'm an avid woodworker building mostly furniture and I've decided to start building my metal legs rather then purchasing them prefab. Wasn't sure how to get started so this video has given me some great tips to get going!
Your bolt cutting method will damage the thread.
Use spare nuts when cutting a bolt in a vice. 2 locked together means you can lock the vice on the lower nut. File the top of the bolt after cutting the run around and put a bit of a champer on it. Where the thread meets the top, use the file parallel to the thread angle and and cut the thin metal away to make the thread lead in. When you remove the top nut it may cut a small piece of metal out of if the lead in wasn't cleared. clean that up with a file.
When cutting thin bolts the top nut doesn't provide a stable support so put an extra nut on the bolt first and wind it down the bolt a ways. Then lock the 2 nuts on as before. Now wind the lower nut up so that it will be near the bottom of the vice jaw when the lower locked nut is in the top of the jaw. Lock it in the vice and go as above. No damage - nice lead in on the thread.
Thank you! This is an awesome tip!
THis sounds awesome. Wish it had pictures for dummies like me.
I had no idea how to work with metal until I have found this video. Great thanks!
Great info! Thanks for sharing, David. This was a really good primer.
Pun intended?
Great video, Thanx for sharing !
Some great tips. Thanks for sharing. Best wishes from Yorkshire, England.
Glad you found it helpful!
Great intro to working with metal thank you!!
One suggestion I have is to make aluminum covers (1/8 inch works) for your vice then when holding things like screws you will not mess up the threads. When I worked "with the tools," we chucked a tap in the Bridgeport mill using the cycling on, off, reverse back and forth. Usually not anything smaller than 1/4 inch.
Thanks! Make more vídeos of this
thank you. that was very helpful. new welder here..DIY fan
this is really helpful tutorial. great teacher
Lots of great information. I would really suggest using oil while drilling though. And WD-40 works well when drilling aluminum. I destroyed way too many twist bits before I realized the problem. Another tip that has been really useful for me is to put the tap into the drill press (don't turn it on), to make sure it stays square to the hole. I'm not trying to nitpick; that might be useful for your 2nd installment.
The tap in the drill press is a great thought, I've done that as well. Great tips here, thanks!!
I'm a complete newbie on metal working, so no tips but a big thanks as I found your video very educational to me.
Great! There's so much to learn, I actually enjoy working with metal because in some ways, it's less finicky.
David Lyell I agree, and gives a better shiny finish
Awesome, thank you
Glad you found it helpful!
Smart idea trying to keep up with current trends.
There was a particular female editor who is no longer employed at PW that wouldn't have dreamt of doing this show.
Bravo to the new way of thinking.
You may actually bring me back as a fan.
Thank you
Great tips, thank you for sharing. What is the make/model of that metal chop saw?
That is an Evolution Rage2. They have several models, I also have the professional version, the blue one, and it's an incredible machine.
The other day I was cutting metal with a brand new drill bit and I took me 2 hours to drill aluminium
-I had the drill in reverse
I have never met a clean metal shop job. Woodworking gets dirty too. My company works with fiberglass, wood, polymer, metal, and wiring. I work in the metal shop section at my facility.
Since you are making this for woodworkers, another common tool they will have is some sort of rotary tool (Dremel). For simple stuff like cutting aluminum, they work ok.
yeah! I use it to cut steel too, M6, M8 threads can be cut easily with it. Dremel 3000 is the one I use.
Gracias...
You didn't get a complete fill because it was a flux core welder :) time to learn SMAW! Thanks for your excellent video. I've referred it to a few people who are just starting.
a good idea for cleaning the weld is not using the angle grinder but use a small pneumatic handgrinder. its for fine grinding and such . sorry for the imposing opinion
is the motor for the wood chop saw and metal chop saw different in specs?
Thanks sir, I am a 13 year old boy who just started metalwork after I have mastered woodwork. I am a hardworking man who is capable of doing hard extensive manual labour
Now you are 15 how much did you progress
mech tech 6?
wow
This video is super good! We'd love to have you build us a "intro to metalworking" or "intro to woodworking," course for middle and high schoolers, and we can probably mostly use videos you've already made. We have a catalogue of cool electives, and this would be a good addition. If you are interested, we have a revenue sharing model.

Never blow metal shavings.... use a brush to sweep up or a shop vac...
Blowing shavings away is a sure way to end up in the ER real quick..
Good taps can be driven in one pass. Good taps are not from Harbor Freight. Also, a good synthetic cutting oil ( not 3 in 1oil) will provide good and proper lubrication. Drilling a hole in metal is not one size fits all. You demonstrated using a center punch. That’s fine for No.7 drill bits. But it will not work well for a 3/8” bit. The center of the drill bit does not drill anything. The larger the bit, the larger the pilot hole. High speed is relative to the work. High speed on an aluminum stock will result in balling up of the metal. High speed on ferrous will cause heat damage unless a cutting oil is used. Lastly, use a face shield. Safety glasses are insufficient.
You need to approach these projects with more knowledge and confidence. Wear gloves. Leather gloves. Not latex. My god, working with metal is dirty. Go have your nails done.
Plumbing threads are tapered. Electrician threads are not. Extend the thread on a pipe thread to avoid immediate tightening. Stay away from those “scary metal yards”. You might get dirty. I get chills just thinking about them.
This is a power comment if I ever saw one. I agree with everything you said, these are all great points!
always deburr any cuts and holes made on steel
OK I have had to stop watching this! (first one ever!) You may or may not be OK on wood but you need some knowledge on metal! Using a file without a handle is a good way to punch a hole in your hand. Always try to hold your workpiece in a vice. Do not "Get a bit of momentum" behind the file or "Hit it" ..... Hold the file with two hands one on the handle and one on the far end and gently push the file in the direction you are going in!
If you are going to cut a bolt down do Not hold the good section in the vice, hold the waste piece. That way you can hold it securely without crushing the threads! If you cant hold the waste piece simply run two nuts on the bolt, tighten them slightly so the faces are parallel and the bolt can't spin and hold the nuts in the vice (easy to remember that one for some reason)
When you are "cleaning the burr" you should file towards the centre of the bolt to stop the thread having a burr from filing on it!
If you are cutting a thread in a blind hole you need to use different taps! The first is (as you noted) a progressively deepening thread. The second tap has a much less progressive thread and the third is not progressive at all. This allows the tap to thread all the way in. If you are not tapping a blind hole you could get away with running your tap all the way into the piece to give a correct thread for the full depth!
Hacksaws should be held in two hands also (once you have started the cut. This makes your cutting action smoother and allows you to use the full length of the blade without twisting and breaking the blade!
OK ...... I'll stop ranting now ;0)
Stick to woodworking!!! If you’re gonna use the Evo chop saw get a steel cutting blade instead of that all purpose blade
Yeah, I've read there's a big difference, I'll keep that on my radar. Thanks David!
Good info, but "wood file" you showed is actually a RASP. You can improve your videos by not saying "uh" so much. I know it is from nerves and practice before shooting will help immensely.
Jesus christ stop saying uh so much.
Who’s here for school?
