Thanks! Yes it was cheap. The casting holes needed reworked, the belt gears were not aligned well and needed reworked, and its a an odd 110v/ 3phase motor but im really happy with performance even...

2" facemill with 4 flutes testing on aluminum. My max cut is about .015" before spindle runs out of muscle.

Pretty happy with the finish.

Spindle is still working well.

After rebuilding my z axis plate, i now have room for both spindles.

I flat topped a stainless steel slide like butter. I think it has plenty of power for my needs.

I have no complaints about the finish either. Amazing for ebay parts and scrap steel!

I see...

The only issue i had with the spindle is when i flipped the motor to the topside, the belt was misaligned and had to shim the spindle gear up a bit. Easy fix.

I also had to take an die grinder and...

Yes. My vfd came in yesterday, i just got it wired and programmed up the vfd.

It works good. I took a few thou off my old vise jaw to clean it up . The lengh of cut was 1" on a 1/2" endmill...

My guess is the thin belt width (9/16") and gears are the limitations on motors horsepower sizing.

I will see if i can find some gears that will support a wider belt and then think about upgrading...

You may be right. I am not planning to do a bunch of heavy hogging at all. Small bites in steel and aluminum..

Well see, thanks sir!

Double post

Yes, its 60 hz and there is a fan blade in the back of the motor. I have a 110v 1/2hp motor i can adapt if this one does not work well.

Its says its 110v 3 phase. I have a 110v 3 phase vfd coming...
Not sure on delta or wye configuration tho

After further review, i was wrong. Its totally 3 phase

Yeah, Unfortunately, its only 110v, single phase with 2 amp draw.

Closer.

This motors rpm is fixed at 8000rpm, they offer the same one with different gears and belts that is 3000rpms

Search bt30 8000rpm power head spindle and i went with a us seller in cali , yokimm

Very fast shipping.

I took a chance on that bt30 ebay spindle.

Looks like it should work fine..

I am still rebuilding my Z axis rails so I have not cut anything yet, but it sure sounds different when hitting it with a rubber mallet.

I filled my gantry void with epoxy, sand and several sizes of gravel/pebbles. The gantry took less than a cubic foot. My base fame will need about 4 cubic feet.

I am also replacing my round...

This spindle unit looks like it could work? . 8k rpms and mentions milling steel.

I would probably need to switch to the square linear rails instead of my round rails for my z to get any tight...

Thats got a decent RPM range that i havent seen before, thanks. I will bookmark that for another day...

Thanks Sir! I have not seen much for low rpm spindles either. I see some interesting 5 bearing power heads with reduction gearing. ( might be interesting) would bumping up to 2.2kv+ 4 bearing ...

When i said adding sand, i meant like an 80-90% sand and 20-10% epoxy mix. As in i am not trying to make it look like granite.

Any spindle recommendations?

Ive decided to fill the void/hollow area in my gantry with epoxy granite. Then i will fill my Ibeam base voids.

That might dampen some of my harmonics.

Since none of it will be visible,...

Childhood dreams coming true.

Howdy all!

Its been a while since ive posted. I have been focusing on learning fusion360 the last few months. Im getting to where i can draw what i need to keep moving forward.

I decided to...

Machine is still working perfectly. I took apart an old dayton 2 axis vise and used the top part as a low profile vise.
