Hi, all - been a while since I was here. I modified a 20" Lortone jiggle pan (vibratory lap) to have a quasi-reciprocal motion rather than the random-ish motion of the original, eccentric load design. Does a good job eliminating up/down hopping of the rocks and no more "orange peel" surfaces on rocks like obsidian.
I got an offset shaft that a member here - "cpdad" I think - made for me that was great. It has - if memory serves - a 2 or 3mm offset. The new design grinds and polishes much better than the old one. One "problem" is that it takes a bit longer and can have trouble getting the rocks moving when they are polishing on a new felt pad. I want try a larger offset and hope I can get one made. I had, initially, been scared away from a big offset after seeing a U-tube video demonstrating the Reciprolap. Just seemed too violent and I felt it could slam the rocks/slabs against each other too hard. I want to try a somewhat larger offset and see if it speeds things up. If anyone can help, let me know. Thanks! Rick
