Decent square

[Sean Troy]

I got the sled's fence to .02 over 88 inches. I purchased a new framers square after checking against others on a flat surface. It got me a lot closer than my original square. The sled is only 24x30 so it will probably only be used to cut 10-12 inch boards so I should be pretty close I'm thinking.

I've trued my framing squares with ball peen hammers and it works. Be careful though if you have to hit too close to an edge that you don't generate a hump. If so, file it down. I also trued my Johnson 8" square inside and out. I made sure the inside and outside of the blade and the tongue were parallel with careful draw filing, then I trued them to 90 degrees and rechecked the parallels. If you file anywhere for adjusting the angles, you don't want to file any more than you can accurately cut, say 1/64". More than that you need the ball peen and center punch and start over.

Check them regularly, and square them again when (not if) necessary.
