Spindle Idea

[SPEEDRE]

Hi guys, had a dream that I could use one of those motors one would find on a mini-mill like the Grizzly model. The LittleMachineShop sells them for repair parts, any comments. I know nothing about electric motors so be kind.

Use it for what? A router? If so, the spindle speed would be too slow to route wood.

[SPEEDRE]

OK but what if I just modified the mountings so I could use the whole milling head ?

Speedre, you could use the spindle for routing but it would be way slow, the bearings in that head for the x2 mill can only handle about 5000rpm at the absolute max. I have some bearings in mine that will handle 10,000rpm which might do the trick for you.

I have a couple small spindles I am putting together that shoudl handle near 20,000rpm but they are still in the works.

I use two spindles on my little gantry router, a craftsman rotary tool (2 speeds 15k & 25K RPM) for working with wood and a 350 watt servo motor with motor controller that gives me a variable speed spindle of 0-6000 RPM.

I have converted a mini lathe to a cnc spindle and it works great so far.
Here is a link with some info and pics. Some of the stuff have been modified and changed a little since these pics were taken but only for ease of use and repositioning the speed control box to gantry leg.

Did you start with
This lathe ?

Hi Dave,
It's Canadain Tires small Mastercraft 12-in. Wood Lathe. You can get them on sale for 99.99 sometimes.

Very creative application of available items. The motor and motor controller are worth the price.

Hi, I've been thinking about using my hand piece (flexible shaft) that came with my Multi Pro Dremel, I never use it anyway. Do you think it would make a good spindle ? Before I hack it

Look under accessories

I always thought the Dremel and its accessories always had a ton of slop/runout in them...

Java, how's your machine coming along ?
