Buried Treasure: Deep Cleaning a Used Polishing Lap

- In this video I take a saw blade to an old polishing lap to remove a layer of grime and reveal the gleaming surface of the metal that was hidden underneath.

Incredible Transformation of a lap that I can hardly imagine was usable for anything but as a master lap (as suggested).
Thanks Justin, you saved me a trip to machine shop, I had a zinc plus lap that was scratching and I used this method and now it works good as new… 😀🥳
Excellent news! Good luck with the polishing.
Thanks
Very useful video, great presentation and demonstration, thanks Justin. Always enjoy your video's, tips and teachings.
Thank you
Good information. Enjoyed the video
Good lord! Ware gloves. Using for free forming? I looks like animal poop. You did a good job in cleaning it. Throw it in an autoclave now. Looks good tho. You lapped the lap. Lo😂😂l
Hi Justin, nice video. One thing is if you trim down the surface of a spinning lap you are going to end up with very (very!) minutely off-flat lap. That is because the diamond saw blade will not cut the same amount of material at the center as it will at the edge. At the centre (let's say at 1" from the centre, where the lap diameter is 2") your blade is going to be shaving down 2"x3.14 = 6.28 linear inches of lap surface per revolution, whereas, at the edge, and in the same amount of time, the diamond blade has almost 19 linear inches of lap surface to deal with. This may be so minute as to be insignificant. (I may, someday, test it with the dial indicator). But it would be a good place to introduce "tramming" as a final touch up in the rehab process.
Yes I understand this but actually it doesn't seem to effect my polishing experience in any perceivable way. There is always a slight difference between my topper laps, my sintered lap, and my polishing laps, so I just leave enough room between the meet points to compensate for that when going from cutting to prepolishing. If I ever did warp it too much from using the saw blade, I can take it to the lathe shop for about $6 but that's more like a once ever few years thing to do for me.
Awesome
Cheers for this , got an pld Chrystalite tin lap I want to clean .
how did it go
@@ValDominator Not good lol , I now have another master lap and just bought a Batt lap instead
@@BrightonGemstones I had an previously unused Chrystalite tin lap that I polished topaz with an I wanted to clean it and I researched everywhere looking for advice. It had a note with it in the packaging that said not to use kerosene. I decided to clean it with tissues and spray-bottle isopropyl alcohol. It seemed to work quite well. I hope it works well next time I charge it and use it.
Loved your video and amazed at the improvement. Any idea what diamond grit was originally on it and what you will now add? Also, having a digital readout of the lap RPM is wonderful, rather than like a 6 or 6 1/4 out of 10 on other machines. Really appreciate your videos. Finally, I know you are in Thailand but where in Canada do you travel to as I am sure our North York Faceting Guild in Toronto would love to see you sometime. Last year we had Tom Herbst come and gave a wonderful presentation.
Don Silverbulletspider not sure about the old diamond grit. I didn’t test it before I cleaned it. I think now I’ve determine it’s a lead or tin/lead lap which I don’t mind in my arsenal. I agree the rpm meter is very handy. As for Canada, I’d love To come. I’ve never been there and it would be great to visit a club of Canadian Cutter’s. I usually come to the states in February around the Tucson show but this coming year I won’t be able to because of immigration and stuff here in Thailand. 2021 is a big mystery right now so I can’t say if I’ll leave Asia at all.
@@JustinKPrim Thank you Justin, we too expect to remain in situ until the CDN/USA border opens -?2021?
Great video Justin, may i ask are you planning on doing any more twitch streams ?.
Sorry but not at this time. I’m focused on making more video courses that will appear in a few months.
i use a razor blade to do mine, this looks way safer. i might try it..lol
Thank you for the beautiful video.how to clean ceramic lap? IF you can please Thank you.
Ceramic lap… I think you can just wash them with soap and water and a sponge. I’ve never used one regularly so I’m not sure.
@@JustinKPrim thank you for your information and for your time I really appreciate it may God bless you.!
kerosene oil is best for cleaning up oil, grease etc,. Pink color is nice in Pakistan it is kinda transparent..😂
Thanks for sharing vedio with us.
Hello sir, I am looking for lapidary machine which can use for multiple facetting gemstone.
Like Diamonds and corundum gemstone. Sri Lankan Gem lapidary machine can use for both?
Please let me know regarding thank you
You'll need two different machines. These machines will facet every gemstone except Diamond. Diamonds need higher RPM's and specialty dop holders due to the heat caused by faceteing.
There is no machine that can do diamonds and corundum. The method used for cutting diamond is completely different that for cutting colored stones. Diamond is incredibly hard and can’t be cut and polished in the same way that colored stones are. If you take diamonds out of the equation the any machine will work because they all can cut almost any stone.
@@xx-vk5ol thank you very much for guidance. I will do check other machine for Diamonds.
@@JustinKPrim thank you very much Sir
What is this machine max Rpm?I ask different Which Rpm we need to cut diamond on Lap?Thank you
This machine can do 2500 rpm. Diamonds is usually 10,000 rpm I think.
@@JustinKPrim Thank you, i follow.
