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

[njhussey]

Had 20 mins before work this morning, drew up a motor mount and this morning cut it out using Trochoidal milling on my router...I wanted to use the "onion skin" method instead of holding tabs but my MDF bed is obviously not level!! The piece finished with the 2 finishing operations around the bosses and outside profile still to do! Still it gives me the opportunity to tweak the design a bit and re-cut it in lunchtime :D

There are 4 off 25mm long aluminium tubes (10mm OD, 6mm ID) to press in to the bosses for spacers which I'll then mill to the same height (should be OK as I did them on the lathe)

Anyway not bad for a first effort I think! Video will be up a bit later....internet connection is soooo slow today!

Video of machining the piece here.....no editing or anything fancy...just pressed pause a few times

Its always nice to see a part that has been designed and machined coming off.

Cheers Clive, not as shiny, smooth and polished as some but nevertheless satisfying

Looks good but pretty certain you wouldn't catch my fingers in the slot with the tool that close while in cycle!

Yes not a practice I'd recommend....in my defence I've run the simulation 20+ times so knew it wasn't going to rapid on me anytime soon....however I'll agree, no excuse

Good stuff Neil.

Was that a Fusion 360 part or i-machining?

One method I've used to avoid faffing about with zeroing off of a part like that is to cut a holding fixture in the bed and then use the same zero to then run a contour pass(es) to clean up the part.

Of course you know Jazz is going to turn up soon and goad you into cutting deeper and faster ;)
