I'm going to be working on one shortly, most of the parts have arrived, i just gotta find the time! Here's my part's list:
Vollrath 78730 - bain marie, $13.46
Vollrath 79080 - lid, $6.86
Silicon Sheet - for o-ring gasket, $8.49 for 8"x12"
type F camlock, $3.92
type B camlock, $5.52
NPS locknut, $5.51 (quantity 2)
SS screen(2), bolt, nut (to keep media in place)
stainless bar, bolt, nut (all welded, to clamp lid on unit).
The plan is to use rice hulls as media if i'm just filtering, or leaf hops if i want hopback + filter.
I suppose i could have bought a hoprocket($125) and save hours of work... but DIY is way more fun than buying!
