Made a post earlier but must not have hir the post button. I have 5 blades going and am working on a couple of things. One trying to partition off a tumbler to take several blades and also working on a stacking method that if it works means that I can have several mediums going at once and instead of buying several tumblers I will only need to buy several Tupperware containers which would be much cheaper. Will be out of town Friday through Tuesday for my Birthday so will post next week on the results.
