So I'm going to be getting 2 vibratory labs, The guy isn't really sure how to use them but said that the moss is used for every stage of the lap... I looked up some videos and the videos show the stones being only on the metal. The laps have a smooth metal bottom to them with no grooves.
So I guess i'm wondering if the moss is used for every stage or only polish stage.

The moss is only for the polish stage. If you have fairly smooth cuts, start your first grind with 220 grit.

Thanks!, I'm presuming that a flat lap can polish anything flat (like kind of heavy book ends)? I'm going to see how they run tomarrow... I know i'm getting a great deal though.. 2 flat laps for $150. The guy i'm getting it from hired me to work for him for his business and lapidary on the side. He is also a Kingsly North dealer so he can get me anything I need at his cost

Well I went to go look at them and both of the motors turned really slowly for some reason... he wasn't sure why but he will look at them to see why... maybe its just his shop i'm not sure. I'll get them when he figures out the problem or how they work or whatever it it.

Try oiling the motors, worked for me. Bought one with the same problem, 20wt. in the motor bushings solved it.

If the laps are aluminum, never use grit courser than 220. With iron or steel laps, you can start with 60/90. The weight of big book ends will take a toll on aluminum laps. I do not do bookends in my aluminum laps.

I have a 20" vib flat lap I'd like to start using, bought it old and used but supposedly working. What is the moss you talk of and is it going to be required to get a shine?

I can't say that it would be required since I don't have experience with one yet, but i'd imagine it helps a lot.

I. like John, was also confused by your use of the word moss. That is simply a very short pile piece of carpet Glenn.
Only used in the polish stage. Can't imagine trying to polish without it.

See if bearings can be lubed also. I picked up two ancient Lortone laps a few years ago. One was supposed to have a bad motor but it turned out the bearings were bad. Found some online cheapies and away it ran.

johnjsgems- Are you referring to the motor bearings? I have 2 FL15's and just looked for the bearings on the parts list and didn't see any. One of the laps is very loud and banging. I figured it was the motor self-destructing. Thoughts?

The one I had apart only had a motor bearing at the back of the motor, the bearing the shaft went through was in the frame of the unit, I assume it was made that way to eliminate the need for a coupler. Assembly was difficult because the magnets in the motor made it hard to center and it needed to be centered to spin properly. Lortone has completely redesigned their vibe laps and may not still sell all the parts for the old ones.

I was thinking in gold recreation terms (miners moss) its the same stuff Although, I guess thats what happens when you live in a gold state and have miner friends. As for the machines, well, I don't have them but maybe I will get to mess around with them at work, not sure but i'm not going to ask much since the guy is my boss starting tomorrow

The shaft bearings, not the motor. I don't remember what they looked like now. It was a few years ago and my mind is a few years older too. They were very old and colors that appeared to be original but unlike any Lortone colors I've seen. Both were set up different from each other too so they made changes throughout the years. I went to one of the online bearing suppliers and had no trouble finding bearings. I think shipping was more than the bearings. Most small motors like that will have a bronze bushing in motor end. I don't know if you can find those easily.

before buying any vibrating laps, use a straight edge and see how much the pan is cupped. Some machine shops will be able to turn a cupped lap. Get the model number and look up how much replacement pans cost. A few lap pans are no longer sold.
