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

[njhussey]

They look very similar to these (which I'm planning to buy): Aliexpress.com Ball Nut Housing.

If anything I'd say they are lower profile than the one you've drawn up. The bottom bolt holes are in slightly different places but I'd be surprised if that was critical.

I've asked for a price for 4 off (I can't see anything apart from a 3 off listing) so will see what they, well the 1610 ones, come back with as they look exactly what I'm after!

Just received some spiral flute taps from China so once I've welded up the frame (should have all the parts cut by the end of today as I did all the 50x50x4 box this morning and just have the 50x25 bed supports and bracing angles to cut at lunch!) and got some Ali cut for the gantry I can start drilling and tapping to my hearts content

Edit.....yep all steel for the router frame (not support frame) is now cut. Welding starts tomorrow
