Re: Ebay Chinese Routers (CNC3040) - anyone purchased one of these machines recently?
Before I forget yet again, a public thank you to JohnS for the loan of a single speed Kress (he also machined up a collar to make it fit inside the original motor clamp) allowing us to carry on machining!

Today I've received the replacement spindle from the ebay seller love-happyshopping, it doesn't seem new but at least works, I hope it will last more than the first one... Anyway I'll probably buy a kress spindle.

Just to add to the FAQ ;-)
Spec on the spindle supplied:

No.
Your first post on this forum suggested you want to build your own. Why not? It's the only cheap way to get a good machine.

I thought I'd share a couple pictures of what my eBay CNC3040 was doing today. This was making a pocket in 6061-T6 (heat-treated and artificially aged) aluminium.
Initial go-around.

Finish looks respectable on the flat, but a little rough on the sides?
Looks like a 2flute HSS cutter? What diameter, spindle speed, feedrate, depth of cut and stepover did you use out of interest?
My machine is currently running cutting a huge aluminium sheet at 780mm/min with an 8mm single flute carbide at 2mm depth of cut. It's been going for hours at that...

I'm amazed that spindle managed that and will be even more amazed if it survive's cutting more than 3 before giving up the ghost.!!
