Fingers crossed it'll cut ally

[blackburn mark]

Iv been having way too much fun researching, learning new skills and dreaming about how well it will all work out… I guess its time to put my penis back in my pocket and crack on with actually getting somewhere

This will be a small and hopefully stiff machine, I’m only really nervous about my choice of stepper driver kit (Chinese 5axis TB6560) I could do with the extra axis to run a 4th axis…… So….. If anyone can offer any optimistic words about these Chinese driver kits pushing a router like this through ally and delrin I would be much obliged.

Ballsrews 1605s
THK-HSR25 pre-loaded for the X and Y
NSK-LH20 for the Z axis but I’m not to sure I want to use these as they are not pre-loaded but I couldn’t resist them at £16 for 4 (new)

The spindles I’m in the process of building... the small one I’m trying skate bearing on with Belleview washers (not to optimistic about those but A/C bearings with an 8mm id are hard come by) it runs at 10000rpm flat out with 12v
The larger motor runs 2800rpm flat out on 12v and maintains loads of torque down to about 1000rpm, Iv an ER11 collet chuck with a 10mm shaft on its way which should drop straight in with the double row a/c bearing at the nose
Anyway… cheers to anyone who has ever posted on mycncuk, Iv had a lot of fun reading of your trails and tribulations
Ps the gantry sides are heavy extrusions… I couldn’t be arsed drawing them in :)
