D1-4 Mounting plate

[Toolmaker51]

D1-4 Mounting plate has been made so the work holding devices from the lathe can be used on the milling machine or drill. This can be bolted stright to the table, angle plate or the rotary table etc. The Home Engineer

Excellent utilization of workholder; always a good idea. That would fixture a chuck, faceplate, spindle nose collet closers etc., orientated besides flat on the table makes it & them even more useful. Vises alone not that good with cylinders in general.
I'll offer another. With a rectangular plate of somewhat thicker proportions, clamp mounted chuck over the side of table; allowing work on longer shafts than what a quill/ knee/ & part height accommodate. Tee-slots offer more strength than the mounting slot along front of table, per my front mount arrangement. That was created because our chucks were D1-6's and 8's, just too big and heavy. http://www.homemadetools.net/forum/t...t-holder-55207
These work of course, only where the ram swivels out of 'normal' area over table.
