Comments sought on new build: A CNC Router for RC Gliders and Planes

[njhussey]

Well I've stopped buggering about and started drilling and tapping the first (reference rail) rail. I put the two reference sides of the rails together , as suggested, and I couldn't get a 1 thou feeler gauge to even start to go between them.

I've drilled and tapped about 7 holes so far with my set up as below and all the holes are nicely central with approx 1/2mm each side of the hole so plenty of room for any adjustment if needed.







Tooling plate is on order but will be 5-6 days and now going to order a straight edge from the same place as Silyavski in Germany to make sure that there isn't any (or negligible) twist in the rails.

Thanks for all the comments and suggestions guys!
