Hi,

I have several 1-2 pound faced Jasper and agate specimens Id like to polish as shelf queens. Polishing them flat on my 6" wheels would be futile and I don't want to spend the time/wear and tear to do a curved contour polish on the wheels. Is a vibrating flat lap a good way to go? Any tips/tricks to getting a good polish using one (do you need multiple pans to keep the polishing clean?

Any advice welcome.

Thanks!

-Jeremy

Vibrating laps are the standard method for this.  I have used both a 24" vibrating lap by Diamond Pacific and a 24" rotary lap by the same.  I hated the vibe.  It required constant attention and did a lot of damage.  For the rotary I bought 1/8" phenolic, backed it with magnetic sign material and charged the plates with diamond paste.  Six disks gave me a very fast system.  Unfortunately, the whole shebang fell off the trailer during our move to Texas and I need to do the disks all over again.

I have had great results with Bobby1's dry sanding/polishing method. It works best with 8" expando but also works with 6". A link:

Interesting approach - kicking myself for not buying the used twin arbor that was for sale when I bought my saw- would have been great for this.

I built a sanding arbor and a carpet polishing wheel unit that I am teaching the process on as we speak at the California Federation of Mineralogical Societies' Earth Sciences Studies event at Camp Paradise in Clipper Mills, CA. People don't believe me when I say I can sand and polish a slab of Obsidian in 15 minutes but I show them how I do it. Its a lot of fun teaching lapidary here at the camp. Next month (I think) my monthly article will be on this process.
