World of Faceting Machines Ep.8 : Dressing Your Laps

- This episode features the Sri Lankan technique for dressing and prepping a metal polishing lap.
I want to point out one mistake I spoke in the video: around the 3:00 minute mark we used a 1200 grit topper lap not a 300-400 grit lap to smooth out the metal.
Finally one thing I would like to add to the content of the video is that if you are rescoring during the polishing of a stone, you don't need to go through all these steps. A quick 30 second scoring and then smoothing out the metal with diamond slurry and a piece of synthetic corundum, then a good alcohol cleaning and a fresh coat of diamond powder is all you need.
Also, I never intended this video to be an example of the "BEST WAY" to polish a stone, only a complete demonstration of the technique of scoring a lap.

Excellent video Justin, thank You so much for sharing. I Was wondering how to dress My laps and with your video it Will help me a lot.
Thank you for the video. Clearly there is no "right" or "wrong" way, just techniques to add to the tool chest for use when the "standard" ones aren't cutting the mustard (or polishing the mustard). I'm a fan of copper and find it works well as a prepolish lap. Good presentation from folks that are clearly professionals at what they do.
This is brilliant!
Can’t wait to try the copper lap I just got
MORE VIDEOS PLEASE!!!!!!!!!
Hai justin saya dari indonesia apakah alat itu berfungsi untuk finishing batu agate,atau batu apa sajakah yg bisa berfungsi untuk menggunakan alat tembaga itu terima kasih video yg sangat bermanfaat🙏🙏🙏
Does the second round of scoring have to line up with the first? or how much crisscross should it be done at?
I it
Not it can be as chaotic as you want. Chaos is the goal actually
Yes, glad you pointed that out about using the 1200. I was thinking to myself that it couldn't be 300-400 grit. Anyways I loved your video. I am wondering about your machine. Who makes that machine and what do they sell for there? Could you point me in the direction to acquire one? It seems like it must be much faster than other types of machines as it seems that you could change the indexes faster...am I right? Thanks for your help in advance.
The machine is great. I teach on them and I think they are some of the best machines you can use for speed, accuracy, and cost. You can find them here; sterlinggemland.com They are about $1200 plus shipping and import duties from Sri Lanka. Nice people as well.

Okay I’m a brand new. Wholy cow, it’s getting expensive. It’s okay, I’m all in. Facetron and all! 😂😂😂 my mom always said do well or do t do it at all. She is right!
Do well!
@@JustinKPrim it’s been kinda weird. I started off getting a vevor a junk and got burned. Got my money back but was told to junk the unit. No Im keeping it as a reminder. I think I’m on the right tract, order the stuff mentioned in your videos. I wanted get the ceramic disk but at $600. 😂😂 I got the tin lap. I’m going all out. Retired Emergency room

@@timlee2109 if you ever want to make space, I’ll take the vevor. I’d love to make a warning video so people stop buying that piece of crap 🤣
My Batt Lap is scratched. Thinking of doing 800 grit wet sand. Would this harm it ? Thank you.
Is the scratch really causing problems? My bat lab has like three huge gouges in it and I still use it just fine. If you really need to resurface it, you could use a used 1200 grit topper like we do in this video. It’s not something that I do very often, this was the Sri Lankan dude showing me how to do it, but I have done it before and it does work. Check out my other video called “uncovering a buried treasure,” where I take a totally disgusting dirty lap and clean it like that.
Man I wish I could get one of those machines. How can I get one?
Email Sterling and order one. Sterlinggemland.com
@@JustinKPrim I wish it was that easy. There way out of my price range right now. Maybe I can sell enough rough gems to get one
I had fear to make groves with paper cutter on copper lap but doing later and I thought I'm the only one. In Pakistan I talked to few cutters they said I'm fool ☺
U r not the only in Pakistan there r so many crazy in work who leave u behind technique in not mother. Of any body else too much talent hidden in Pakistan Pakistan zindabad

How we dress greenlap?plz make one video..
Greenlap... good question. Mine is plastic and doesn’t need dressing but the ones in India and Israel, I’ve never seen one in real life before so I’ll found out later and make a video.
@@JustinKPrim yes it is indian one chrome oxide polish lap
You'd think this guy would hit the doctor's office to get that staple or screw-eye backed out of his finger.
Obviously that must have hurt when it happened and I'm sure it'll hurt when it's removed. But surely it's got to be better than getting i caught on everything and half yanking his finger off.
And besides, it just looks goofy !
I thought all the guys on the gemologyonline forum say never to score your laps.
its2in0the1numbers1 they do. I learned from GemologyOnline as well but this technique was taught to me and works well.
Interesting. The sri lankans must know what they're doing if they're the ones who use and make these machines. I'll definitely look into this (and watch your video again). Thanks.
Scary to imply this is the proper way rather than a technique that some use
D L owens I only meant that this is the proper way to score, not that scoring was the proper way to polish a stone. That choice is of course subjective.
