Ignore the long stainless tube and the excessive clear pipe. My stainless cutter is in the van so it's just like this for testing. Pipes will be curt down and meet each other were they currently are.
Idea was that's a 12 volt vacuum pump, so was gonna firstly have a fag lighter wire on it to use from your car, and at a latter date retro fit it with a 12 volt rechargeable battery.
Quite compact, not heavy and just makes abit of noise.
But currently struggling to get enough pull to stretch a grip enough.
Not sure if there's a leak, the tubing is to long, or the pump just isnt manly enough.
Hoping to do more testing next weekend.
