I'm ready to fire up my new/used 15" Lortone vibe lab. I am confused about the weights. If I am going to use lead, how much do the weights need to weigh??? I found some nifty lead disc weights online. They look like donuts without a hole. They come in 1-5 oz. sizes. Using these would sure make things easier. What do you think?? Question 2, how crucial is it to use "graded" grit? Thanks for your help.

Question 2, how crucial is it to use "graded" grit? Thanks for your help. Why are you using weights if you don't mind me asking ? For coarse grits like 46-60-80-90 you should have no problem mixing them. 220-500-1000-polish, I would just graded in most cases especially if starting out. I coarse grind with a mix of 00-0-1-4-8-16-30-46-60-90, a wild mix with pea sized silicon carbide chunks. But almost always move to 220 after coarse grind. with some vibes you can skip some abrasive steps but best to wait till you ave some experience.

Thank you for the grit info. In my newness my weight question was unclear. So let's try again. Am I correct, that you need some kind of weight on slabs etc. so they keep good contact on the lap?? What do you make the weights out of? Lead or ?? In one article the fellow was pouring his own lead pancakes to use. I hope I was more succinct with my questions.

Methinks a vibe tumbler was confused w/ a flat lap vibe, no? 3 steps to polish on flat vibe lap- 220, 600, and polish. I made my own 1lb. lead weights, w/ an ingot mold purchased @ Dick's Sporting Goods, in the reloading section.
