Yes I see Dick is still posting and he mentioned recently that the press was his preferred method. I can see how the spring method would work. I do prefer the vacuum bag and I am well set up to do it including a back up compressor and vacuum tank with Festo vacuum switch. The reason I used the press was the PVA glue needing to air dry. I will be going back to bagging for my next project as it will have no honey combing and a full paint finish.
