My messy shop, I have one build going on plus my wood/golf ball carving and I have stuff getting charged up for flying tomorrow, crap everywhere!! I was able to move some stuff around and find what I was looking for, that just means I was able to open a drawer and get to the bottom of it. I found two of the old shims I was talking about, they are made out of plastic and are marked. I did a scientific measurement and sure enough, using all my high end precision tools I discovered the markings on the shims are correct. KINDASORTA. My thin shim is marked 1 and it is 1/16 thick then tapers, it came out to one degree or close to it. The other well used shim is 5/32 and marked 3 and it came out to about three degrees. I used to use these a lot in years past but for the life of me I can't remember who made them. Anyone know/remember?? These are good little items to have on hand, I have been making them out of ply but the plastic is cheaper and easier!!
