    Please make more videos like this! In fact doing another full-on beginner series would be pretty cool.

    Can you use the dual-band system for cutting grits as well?

      @@vzanchi I wouldn’t. Cutting grits are a lot more damaging if you do get cross-contamination. Better to be careful with those. For me, I never use loose grit Diamond for Cutting. My cutting lamps are all sintered laps. Safe and easy.

    I just ordered a bottle of Singer Oil just to try it out. I have 3in1 which as you say is smelly. I only use it to keep my machine in good condition.
    I really like SNAKE OIL (SO) for polishing but I'll give the Singer Oil a try since I'm getting low on SO. It'll be here tomorrow ! Can't hurt to try it. 🙂

    Hey JKP, as always an ace video. Just curious, do you know of any companies that either do, or could, make a dual band sintered lap? So, something that cuts on the outside and pre-polishes on the inside? Thanks in advance!

    • @JustinKPrim

      @@rigbyleigh there is a company in Geneva that makes sintered laps to spec and I think they would do it. I assume it would be quite expensive as their normal 6” sintered is around $600 so a dual band is probably closer to $1000. Sadly I have the company in my saved emails but can’t find the name right now.

    Good morning Justin. I speak here from Brazil. I was born in the largest gemstone producing region in our country, in the State of Minas Gerais (city of Padre Paraíso). My late father was a great prospector and stone trader. Now that I have retired from the police (Investigating Inspector) I will go back to dedicating myself to my old job. If you want to hear good stories about real treasures, just let me know here.

    I will add what they really should be careful about lap contamination, if you people use some brush to spread water on your finer topper laps when you are making your facet surfaces smoother before polish, dont use synthetic hair brushes that are for applying synthetic latex paints... (better use more water dripping on lap and let it spread naturally by g force... it happened to me that i was starting getting scratches on my almost smooth facet surface and i wasnt able to figure it out but at one look i found my green hairs from a brush on the lap and they were making scratches as they have been slowly cut off on the diamond grit embeded in a topper lap, so be careful and dont use such brushes :)

    like you need a layer of diamond powder. It doesn't make a difference what type of disc all you need is a layer of diamond powder stick/glued on the lap .
    I had experienced the dry layer of diamond powder worked better without any chipped/ditched off from the disc .

      @@JustinKPrim I was talking about only for polishing or pre polishing . As you placed the diamond powder and oil past on disc after polishing few stones like topaz or harder stones the past turns into transparent but hard and dry layer of diamond past you can put one or two finger tips diamond past before any chip off or ditch on the lap it turns into very hard layer . Keep putting a small finger tip of the diamond past not much oil, I use olive oil . At that time I wished I had a big diamond which I can use as a substitute for any metallic , plastic disc .
