I will be mounting a dead length air collet closer to a lathe spindle
for an upcoming job. The closer is meant to be fastened to a
stationary object. See the link:
It links to one being sold by Iggy.
Anyway, the one in the link is identical to the one I have and as the
link shows there is a big boss on the side that is tapped for air
fittings. I adapted mine for rotary table use by drilling holes in the
base for the air. The closer bolts to a base that bolts to the 4th
(rotary) axis in the mill. I made a two passage rotary union to pass
air through the 4th axis and into the closer. It all works very well
but the 4th axis spins slow. Now the closer is going to be in a lathe
spinning at 4000 rpm. I'm thinking that at that speed it should be
balanced. Would placing two weights, each at 120 degrees from the
boss, be better than one weight placed 180 degrees from the boss?
