FOR THE HUNDREDTH TIME

[@SackettGems.]

Great video, always wondered if the hundredths on most diagrams (and some machines) were there for true accuracy or simply the illusion of it. Keep up the good work!

This was very helpful, thank you. I actually feel relieved now.

I was able to reduce the flexion on UT VL by rolling a little piece of Teflon tape around the height adjusting bolt.

You're the best I'm so glad you put out a new video

Hello, John Nevertheless, if u are cutting your gem with UT v5 using a soft stop, it works well with 0,01 U get absolute presise meet points... But after transfer, u get probably a tiny error with meet... If u use other machine... or v5 with hard stop, u will never get the 0,01 precision 😊

The lap itself is variable, I have ceramic laps which have a higher accuracy of flatness, the most accurate lap I have is an Aluminum Oxide Lap, and it's machined, I am making conical shapes, so the amount of material in contact with the lap is the min amount. the variance if the diamonds is the issue. For me I am not making the flats, and its nice to know that the pressure and quality of the lap really matters.

im actually looking at buying a copper lap for rough grinding (like 100 grit or so). Do you have a recommendation of a good site for a good copper lap?

[@gemstoneartist]

I don't have a specific supplier of copper laps that I like. The last one I bought was from Gearloose, but he doesn't make them anymore. The real issue is flatness. And, if they're bonded e.g. to an aluminum master - that the bonding technique remains stable across time and temperature changes, etc. I'm finding sinc a much better material for pre-polishing, as copper has a higher friction coefficient (more likely to produce orange peel). And, the zinc are also more available in the market. Maybe this will be useful to you...

Can this dial indicator be fitted on a Seatle Face-ette?

[@paraglidingklamath]

Sure. The connector attaches to the dop. Anything with a 1/4 inch or 6mm dop will work with this connector shown in the video. If you have a different sized dop, just search out a different connector to hold the dial.
