Is there anyway to correct a try square that isn’t true? I brought back an old one that my Grand Dad used to use but it isn’t true, is there anyway to fix this?

Here is the square, a bit worse for wear but should clean up nicely if I can get it square.

There is a way to tune up your square. I have done it before. It involves tapping the flat side of the blade close to the leg. This tapping, when done correctly will open the angle and close the angle. I will caution you to do some research into this subject. It takes very skilled hands and knowledge of the techniques to get it right. You could begin by looking on the net info on tuning framing squares. They are done in the same fashion.

Nice tools.

I’m trying to dig up something I know that went over making squares like that which would help point out how to fix it.

You should also check to see if its just blade wear that is making it off or if the blade moved in relation to the handle over time.

If its the latter you should be able to fix it with a few pieces of brass round (knock the old pieces out set the square and pean new ones in)

Hi Damien;

There are actually three ways to fix the square. The easier two have been mentioned.

When peening a square, use a semi rounded over nail set, or something along those lines. To have the blade move dimple the corner that you want to close. This stretches the metal and pulls it back into square.

The center pins on the diamond may be a little loose and have allowed the blade to move. You can try tapping it back into place with a dead blow mallet. If you’re able to get it to move, peen the pins in tighter.

The next method and last resort would be to grind or file the two edges of the blade. This is if the blade is only slightly off.

Have fun,

Lee

Could you explain peening a bit more, not sure I fully understand the process.

Peening puts dents into the steel causing it to expand.

If it off a small bit you can rub the body of it on a piece of sandpaper taped to a good flat surface. Put pressure on one end or the other depending on which direction it’s off.

I don’t think I would mess with the blade if I could avoid it.

I just made a post on squaring a carpenters square which shows you how to use peening.
