Dan,

I have been looking at a vacuum adapter for my 1642. So far, the best option
looks to be the one offered by Craft Supplies

Haven't got a vacuum pump yet, so I haven't done all the detail work to
insure it will fit, but the only question would be the length of the
threaded rod, which could porbaly be easily replaced with something from a
hardware store, if needed.
