Upgrade spindle

Hi,

I would value any opinions you folks might have on the following.

I have a gantry router that has a Rockwell 6302 router motor on it.
I would like to put a variable speed spindle on.

I have (on occasion) machined aluminum on this machine and would like to do more of this sort of thing.
I can't run at high production speeds (DC steppers), so a spindle with 1.5 to 2.2 KW is about all I would need.

If at all possible, it would be great if I could find something with tool changing abilities as well, with say an ER20.

(Not asking much am I !)

Any advise on something that would work well with LCNC would be appreciated.

Thanks to all, Allen

The problem will be just the mechanics, that is not directly related to LinuxCNC.
Basically all solutions will work with LinuxCNC, as the interface between LinuxCNC and the motor that will be on your machine will be most likely a VFD, that is very common in all LinuxCNC machines.

I knew a tool changer would be a challenge $$$$, my Walter Helitronic Large Power ran ISO 50, the machine was ghastly expensive and the tooling/support equipment almost doubled the cost to set it up. I sold my shares in that company due to all the money we were spending.
We never made enough for ourselves to have a descent payday, it went on and on and on, at the eight year point I walked.

I saw the unit on Ebay, it's not a bad deal, but I have less than $1500.00 in this machine (I bought it busted and fixed it) and I need an affordable solution or I may as well have stayed vested in that corporation. Unless a 1.5 - 2.2 KW w/changer come along cheap I'll most likely do a cheap spindle.

Thanks for all your help folks.
