Mounting a toolmakers vice on milling machine Paul M 03-29-2008

Hi

I leave a larger vice bolted to the table most of the time and I also
leave a small homemade indexing fixture on the table.
The larger vice`s base was already pre drilled and tapped both ways
for the fitting of buttons and I made my indexing fixture in the same
manner.
The smaller toolmakers vice however is useful for smaller and more
awkward jobs but these only tend to be once in a blue moon hence the
requirement to basically place the vice on the table and bolt it down
wihtout too much fiddling.

Cheers

I know from experience a carbide tipped end mill will gouge chunks out
of this particular vice - it was on its first real job too.

However producing controlled holes in specific places will be several
orders of magnitude harder than uncontrolled random gouges.

HTH :)

Hi Mike

Sounds like your expense has possibly saved mine!

I may go the route of making a base plate with dowels to locate the
outside edge of one side and one end. The base plate could pick up on
the T slot by buttons and as it would be made of MS the holes for the
dowels would not be a problem.
I could then clamp the vice to the table in the usual manner.

Thanks for the info.
