Hi Tom, welcome to Fadu.
Processing sheet film can be a challenge. I was fortunate enough to pick up Jobo 1510 tanks and roller motor bases while in abundance and before prices went silly.
For my 8x10 film I use paper drums, primarily Durst without a hitch. These are more readily available and low cost.
Rotation agitation is convenient but not how they did it in the 40’s and 50’s!
