I'm thinking of the ones you can get for kitchen cabinets where you slide them out for easier access to what's at the back. Have seen them available online, not sure if they would work in your set up but could be worth researching.
Headshrinker thats exactly what i’ve been thinking. Easy to undo quick disconnect hoses inside the cabinet but the lifting of the canister from inside the cabinet is Getting to be a pain. I must be getting old.
I think a piece of plywood with hardwood on the sides to hold full extension drawer slides and a very shallow drawer mounted on the drawer slides. Hard to explain. Ill try and make one and post a pick if it works.
