maddog Posted October 21, 2010 Share Posted October 21, 2010 This is a simple tool for taking an inside measurement. I find them very handy for checking diagonals of a frame to see it its square. I always find a tape measure awkward. Just a rod inside a tube. The top three are 1/2" sq or round rod in a piece of square tubing. I welded in a fixed point at one end and drilled and tapped for a thumbscrew at the other. The bottom one is just 1/8" gas welding rod inside a piece of brakeline tubing. The fixed point is a piece of a nail. A small bend at one end of the sliding rod makes enough friction to hold the measurement in place.

maddog Posted October 24, 2010 Author Share Posted October 24, 2010 (Originaly a mispost. Edited to respond to comments) Glad you liked the idea. This is a wood working tool. Here is one I made out of maple when I was making cabinets. The lathes are held by a collar with a trapped wedge. When I switched to metal work I couldn't give them up. But after setting fire to a couple while checking hot welds, I decided to rethink the design Dodge, I scrounged the thumb screws from somewhere. Im sure the machine supply houses stock them but they arent really necessary. A regular socket head would probably be fine. Even just a dimple with a center punch would probably work well.
