Toolpost Power Spindle

[cascao]

Since I had created this drawing, cannot wait to see it done.

The quality wasn't good but the layers movie looks cool: https://flic.kr/p/zMin27

Carcass with oil plug and bearing races pressed

Axle, initial cuts


My setup for finishing the axle. It was turned between MT 02 arbor and center

Looks good, Are you making a tool post grinder?

 

[British Steel]

Looking good, Cascao,

Eddy, I suspect it'll be a milling spindle, big taper rollers and Sturdy Construction - a TPG needs smaller lighter bearings to handle the RPM (e.g. "magneto bearings" here in the UK), particularly for internal grinding where you could be running 20-30,000 RPM.

I will use an 1800 rpm 1/4CV motor.
With MT 02 arbor, my plans was to use a small chuck from drill press and MT 02 collets I have.

Great progress this weekend

Milled the keyway and 17mm wrench


Internal keyway on pulley

Are you going to make some sort of indexer for the lathe spindle?

 

[cascao]

Yes, I have done the indexer first

I actually saw that, but didn't connect the two. Will the mill spindle be heigth adjustable?

 

[cascao]

The idea is to clamp the spindle with "U" bolts in slots milled on a horizontal plate welded on the base plate shown here

But, if I can't mill the slots, That's my plan B: https://flic.kr/p/zZDH29 [nice 3D movie from my study] tabs behind horizontal plate.

The motor have his own foot.
Maybe I will add one tensioner pulley after. And of corse a belt protection

Milling the slots previosly done on angle grinder


First test with swarf protection on the washing machine motor




My Sherco observed trials has new brake adjust
