You were there for me in my early days, thank you, but you have joined the dark side, both literally, and figuratively. What an expensive mess you are to clean, dispose, reload, or purchase.
I have made a wood chip barrel to replace you. It consists of two trimmed swiss cheese lids, held off the bottom, sandwiching a bag filter filled with washed chips. When loaded, simply remove, burn, and replace. Results are outstanding.
Thanks to all the pioneers, who have contributed to such an effective, free, and simple process.
I didn't take any pictures, but it's easy to envision, and build. I used a clean metal barrel, with a drain tap out the side about 2" off the bottom. I took two metal lids, and cut the rim curl so they fit the inside radius of the barrel, and drilled 1/2" holes throughout both, like a drain cover. First lid is elevated, and supported 3" off bottom. Sewed a bag filter out of an old sheet with open top for loading/unloading chips. Tie off top of filter bag, and place second lid on top, with steel weight to keep chips compressed, and contained. Top of barrel has sealed lid with inflow tap, and a vent/overflow tube back to settling tank. Chips stay flooded to prevent spontaneous combustion.
That is an excellent way to build a chip drum. If you already have resin and want to prolong its life big time build a chip drum like the one described and stick it front of the resin tanks. May not need to touch the resin for a very long time.
