Very cool! I finally decided that CNC was out of my budget for a while, and have gone the "Make it the best manual mill you can" route.
I like the tapered gibs... any more details about that mod?
Also, what are you using for the way covers? I like the "wrap over" design on them!

Those bellows are made myself with PVC reinforced fabric with web information like,

I dont make cuts in the the edges for fold the fabric, I only glue some strips underside the folds (from the same fabric ) with wide smaller than the fold size, leaving the upper interior edges free for aid the fold operation. Finally I clamp and press the folded bellows between two woods (like picture) and heat with hot gun and it maintains his form.
