I try to build A live tooling With MC 3 for my lathe.
Have a multifix B type toolholder that I use for this.
Think that I need about a 0,75 KW 3 phase motor with a VFD.
The shaft is from a old mill that I took appart some years ago.
Made a block that fits in the multifix , and holds the bearings have to make the part for the rear bearing and than get a motor on it.
Here are the first pics,

Now that is cool! That gets the wheels turning. With a good method of locking the lathe spindle, you more or less have a mill there... or at least good milling capability. That's awesome.

I also have a milling attachment, but that takes me at least 15 minutes to set up. this is a quick change. just for some light milling, and drilling.
Im not sure about the motor i need, want it to be small I,ll quess that a 0,75 KW 3 phase 400 volt ( we have 400 volt 3 phase here in the Netherlands) will do or is that overkill?
1/2 inch ( 12mm) will be about the largest endmills that I use in this, and maby drills upto 1 inch .

That looks like it would be better used as a toolpost grinder than a milling head, but it might work OK. Perhaps instead you can figure out a way to mount the milling attachment directly to the toolpost rather than replacing it. Then you can still use the lathe spindle for the milling tools, with a wide range of speeds and plenty of power. The only advantage I can see for a milling spindle on the toolpost is being able to hold the work in the lathe chuck and having the ability to use it as a sort of rotary table or spindex. For that, you might be able to mount a small drill press with the base under the lathe, perhaps on a linear slide of some sort to adjust the position of the drilling head. You might even be able to mount the post of a small drill press to the cross-slide and use the lathe controls to adjust its position.

Hi
This will certainly be useful addition to your lathe for milling flats slots etc.
You can use the various screw cutting gears on a extension fitted in the bore of the lathe spindle and locked with a taper plug and drawbar.
A locking device into the teeth or a worm drive and you have a dividing head for umpteen combinations.
I have this type of setup on a 10X27 lathe and pleased with the results.

Made the housing for the rear bearing, found a small 3 phase motor and a VFD ,

Nice work spinningwheels.

Live tooling adds allot in a lathe especially for odd projects.

What I did was pick up a unimat lathe and just use the headstock in the compound, or on its pole, or what have you. Does some neat stuff!

Most of my pics don't work any more or I could show lots more.
