bout a foot square... maybe 1.5'.
I do lathe work and make bowls, vases, etc... occasionally i make segments and cut em on my current jig and make 1-2 inch pieces, glue em into rings, glue rings together, turn on lathe...
someimtes i make 24 segments, and my jig is wood.. wood moves.. slightly.. and my jig needs repairs or replacing, so i want to make a new one... but if I'm off 1/2 of a degree on one segment x 24 degrees then i'll have a 12 degree gap in my rings... or too much... so precision is everything.. corian will not move..
this is my jig i wanna make...
