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

Why such a small step over neil.? . . . . With 0.4mm it must have took for ever.?

The Acid test for tram is when you use a wide cutter.!! Try 50mm with 75% step over and see what happens.? 6mm with only 0.4mm step over will hide most error. Also cut both X & Y direction.

The step over was what was in Cambam and gave a good finish so I kept it, yes took a while to surface it. I'm going to get a small fly cutter to do the surfacing in the future so we'll see then!

Going to be spending the next few weeks playing with speeds and feeds on various different materials...looking forward to it

Wide cutter will give you perfect finish if trammed correct and take fraction of the time.

Wouldn't get a fly cutter these spindles don't like them. Get one of these with indexed tips http://www.wealdentool.com/acatalog/...nning_928.html

Or if on budget one of these. http://www.wealdentool.com/acatalog/..._Wing_250.html
