Pretty slick. How well does it work?
Elegant. Simple. Good job of doing ones best to battle Murphy.
Very nice. I'm thinking that it is super smooth in use?
Countless little horizontal mills went to scrap because potential buyers couldn't visualize this.
Driving from the machine spindle infinitely better than placing that weight atop the fabricated spindle housing. And, still have ready use of the horizontal spindle. You say the bore is #2 Morse Taper; appears those are drawbar [not drift] holders?
Sincerely,

Home Made "Marvin" Attachment by glens5 - Takes a few minutes to set up and align but other than that it seems to work just fine.
I haven't checked for run out yet but if there is any I'm sure it'll be from the Banggood collets and holder. "Pin It")

The over arm support is 2 1/2" for the for the horizontal spindle support so I turned the vertical attachment from 3" cold rolled steel.
The bearings are tapered roller bearings, L44643. I turned an extra fine thread on the top of the spindle for adjusting the end play and run out to zero with a special machined castle nut with a round collar that projects through the top seal.
I wasn't able to turn the bearing cup seats with the two sections welded together and was concerned about the weld pulling but with the wall of the housing close to 1" thick there didn't appear to be any distortion. Peening the short alternate welds may have helped too.
Interference fits for the spindle bearings as well as the bearings in the idler pulleys.
MT2 taper with a draw bar. MT3 would have been preferred but would have been too large.

Given my name, I have a vested interest in this question...
Why is it called a "Marvin" attachment ?

Certainly not an original idea on my part but it looked like a good idea for converting to vertical.
