Malcolm,
If I recall correctly Ross leidy made a poor mans vacum system for a paddle, you may want to look at his site to get some inspiration.

: Hello Bill,

: Thanks for that. That's much better than my scale, which is to try
: to remember how much resin I used for the last build of similar
: size, and figure the weight for that! You know, I have often
: wanted to try the vaccum (vacuum? Vaccuum? vaccume?... )
: "suction" bagging. I honestly never understood how the
: resin keeps from getting sucked up into the pump, and never had
: the money for all the what-nots you need to do it. I have a
: hot-rod VW that pulls a heck of a vac on the dellortos. Maybe I
: can just hook it up to that, LOL!

: I'm honestly rather shocked that the resing weighs less than the
: cloth. I thought it would be the other way around. That's good
: to know. Maybe I will come in under target then.
