G'day Bevn,
Found out early when looking into what to build the bellows or constant air discussion is like the Ford or Holden.
A few things drove my decision,
1) Cost - by the time you buy three keene trays and air supply is quite expensive. Then you still have to build the rest.

Evening Moneybox,
My ones are boat motor engine mounts. Hopefully will work out, but will certainly look into the springs as an option if all goes to sh#t with current set up.
Only a little bit of time on dry blower over the last couple of days, life keeps getting in the way.
Riffle trays are done and ready for a coat of paint. Last wall on hopper. Now working out the screen.
