My little welding table DIY accessories

You can sometimes bring a framing square into "square" with a center punch, if it's not TOO far off - if the angle is too acute, make a punch mark near the inside corner and recheck - repeat as necessary, but recheck with each successive punch til you get the hang of it.

If the square is WIDER than 90 degrees, punch just in from the OUTSIDE corner... Steve

Yep... That's how I do it.

You can do the same thing with C-Channel. Take a sledge hammer and place it under one of the flanges of the C-Channel, (used as a dolly). Hit the top of the flange with a ball peen hammer.

Very nice table, will come in real handy for welding projects.:thumbsup:

Don't know if you realize it or not. Those magnets will play havocked with the arc, if you tack or weld near them. Little PITA thing called arc blow!

Uh oh! Didn't know about the magnet issue. Now you got me paranoid and I removed the magnets from my welding table.... dang it! So why are there magnet squares sold for welding???

They are handy for holding things! Just be aware if you have issues while welding with arc blow remove them from the area. I've had issues with them just tacking close to a magnet before.

Gotcha! Could you please explain a little more about arc blow and how to recognize it?

Lincoln can explain it better than I can.

That square is a framing square used for laying out things like stair stringers and rafters. 9 out of 10 ARE NOT SQUARE! You need to use a speed square to set things to square. Never use a framing square to set things to 90 deg -- I've seen them be as much as 1/2" off in 2 ft. Check it by setting the thinner side against a known straight edge - like the factory cut edge of a piece of plywood, ( be real picky about the edge alignment here) draw a line along the outside edge of the fat side, now flip it so the thin side is on the opposite side of your drawn line but aligned along that factory cut again and see if your drawn line still lines up with the fat edge. When I needed to have a square square - and I was buying a piece of plywood at the same time, I took all the squares off the shelf and did that - I didn't find one square.

There are tricks to squaring up a framing square, google it

Dang, Bukit beat me to the punch

Us old pipe fitters are lost w/o 2 framing squares handy and a pipefitter folding rule. We also use two levels w/magnet bases, one for the horizontal piece and the other for the vertical. Yes, you have to check them once in awhile. Buy quality tools and they will be accurate when new and take a lot of abuse to get out of whack. We always kept a new one at the shop to calibrate the ones we carried banging around in the truck and on the job. Pipe fitter rules fold so you can see the numbers with the folded part on to instead of hanging done. Lets you set it on a horizontal surface and read it. Carpenter rule (what you get off the shelf). I have only found them at a plumbing supply or industrial supplier. Come out here some day Dragon eggs and I will show you one and how to use the two methods.
