I have an adapter for vacuum chucking on my DVR. The thing is

The included information states that it is to be used with a vacuum

vacuum pump and what are the specific requirements/alterations to do,
if it can be done?

Thanks

I use a vacuum pump on mine. I epoxied a fitting into the hollow shaft,
filled in the holes on the shaft and screwed a quick-connect male
fitting into the fitting. The vacuum tube ends in a "T". one side with
the female quick-connect fitting and a fine tuning valve on the outer
side. This allows me to bleed in air to adjust the amount of vacuum I
want for the particular item being chucked. It works very well. I only
remove the fitting if I have to knock out a tapered fitting from the
headstock.

BTW, do you have the sheet metal stand? It sucks. Chips cannot fall
through and I have to constantly clean out between the ways. I'm
thinking about making cutouts to allow them to fall through.

Any wire cut to length will be too short.

No, I don't have the stand. I'm making my own.
