yeah shure, I'll put some drawings with it too, for different headtube angles. Theyre acutally really simple to make, but you have to saw them exactly right and you should be able to get the materials. Cause you'll need at least 8mm thick aluminium plates.
BTW: I've made some templates out of cardboard. And it seems that 83 degrees should be fine. Cause I also have a template of 80 degrees and it looked way too sketchy. So should i go for the 82 degree angle?
