I purchased an Jian-Ken JGL-80 water cooled spindle, 2.2kw with ATC. I'm setting up the pneumatics for it now, but will soon be moving to the pump and reservoir. Is there a recommended size of...

@Joe184, have you had a chance to finish your build? I'm thinking about doing a 4x4 Evo 2.0 build but haven't bought plans yet... Curious to know about your overall experience, what components you...

That's a great deal. Where/how did you find it?

I'd like to build my first CNC with the following features/capabilities:

* Able to cut a full sheet of 4x8' plywood
* Two spindles, one for wood and one for plasma cutter
* Removeable water tray...

Interested in potentially making my own CNC router for woodworking, with a capacity around a full sheet of 4x8' plywood. I currently use a friend's dual-spindle custom-made CNC with vacuum hold down...

Hello, I've got a semi-production project coming up that calls for cutting hundreds of small plywood components, many of them just inches in size, out of 9mm thick baltic birch plywood. The CNC...

I'm going to try the drill bit followed by .25" end mill for the finishing pass. For the first pass, it's not necessary that it be a flat bottom, since that will be addressed on the follow-up pass.

Thanks for the advice. For the 1/4" holes on the first pass, I suppose I could use a spiral upcut with 1/4" cutting diameter, right? Since surface tearout isn't really an issue as the 3/8" bit will...

I have a new project that calls for more than 200+ holes cut into 25mm thick baltic birch plywood, for each platform. My overall project calls for more than 100 of these decks, so lots of hole...
