    Brass are more resilient than Aluminum however, aluminum can transfer heat faster than Brass. Brass also transfers heat fairly quickly and they are still soft enough to not likely wreck your laps if you slip.

      That makes sense to me. Thanks.

    I have a set of 5 Trilliant Dops. They were manufactured and sold by Graves which no longer exists.
    I was Very Fortunate to have had my set Given To Me by a fellow faceter.
    I absolutely love them however, I posted a FB question about 2 weeks ago (at most) in a faceting group to see IF anyone thought of starting to make them. While many people would love to have them, even more said the Cone Dop is sufficient. BUT if you don't have enough Wax or Glue in the dop, the pavilion edges of a trilliant can easily get mangled in a cone dop whereas in a trilliant dop, they fit snug and safe from any potential damage. Furthermore the stone cannot twist in the dop.
    Unfortunately, nobody makes them any more and they are like Hens Teeth. And NO I'm not selling mine ! lol
    I just got my new VL Classic Digital yesterday. I understand my Graves dops will fit (same 1/4" diameter) but it's possible they could damage the quill barrel but I cannot see not using my Trilliant Dops because I love Trilliants and I love my dops.
    And to the gentleman that gave me the set that I have, THANK YOU SO VERY MUCH. Trialliant Dops are Excellent and I am very grateful for this gift.

      Yes, I followed the FB discussion on somebody potentially making trilliant shaped dops in the future. Seems like it is too expensive of a project and no one will want to pay for what those dops will cost. I have no idea - but I saw the comments from others, who do know. As far as the dops fitting in your UT, there is no issue. I have one or two old Graves dops that work fine (but I don't have any trilliant dops).

    Hello I am left handed . What is your advice to me for buy left or right handed urtratec faceting machine ?
    Best regards

      I am also left handed. I bought a right handed Ultra Tec because it would have taken a lot longer at that time to get a left handed machine. It has not made any difference in my cutting...right handed machine is fine.

    I have an emerald cut stone. And need to use the "v" dop . Why is the other end flat and not tapered like the other 2? How do I line that back up in my quill after transfer? Thanks

    • @mikesackos2208
      @mikesackos2208 2 роки тому +1

      You like it back up in the quil by setting your machine at a 90 degree angle and selecting an index tooth equal to one of the index teeth that you cut the girdle with (often the 96 tooth, but not necessarily). You put a flat block on your flattest lap and you run the mast down until your stone just touches the flat block. Raise and lower the mast slightly looking for how light breaks out under the stone...adjust the stone until the light breaks out evenly under the stone when you raise it slightly. At that point your crown and pavilion are in alignment and you can tighten your set screw and lock the dop into the quill and begin cutting. It is easier to see then to read about....I have shown this technique in recent videos. Hope this helps.

    Hey Mike, great video. Just wanted to add, that the reason most companies use brass for their dops. Is that when aluminium is accidently cut on a steel lap the aluminium bonds to the lap whilst brass does not.

    • @mikesackos2208
      @mikesackos2208 3 роки тому +1

    • @thegemgarden2757
      @thegemgarden2757 3 роки тому +3

      Aluminum is a softer metal, and bending is the main reason aluminum is not preferred over brass dops. Back in the day most aluminum dops were much longer than the brass counterparts.

    Hi Mike, thanks for sharing your experience, I use wax and then epoxy, when I make the transfer I heat the wax and this way I can detach the stone. In your case, how do you take off the stone when you make the transfer?

    Hi Mike, I use a SMD soldering iron ( air heating) for wax , works absolutely brilliantly . I can dop and transfer within seconds.

    • @mikesackos2208
      @mikesackos2208 Рік тому

      Thanks. I have heard from some other faceters that they also use a soldering iron to remove epoxy and super glue (not just wax) from gemstones after the transfer....I'll have to give it a try....which soldering iron do you recommend?

    Do you use that same transfer block for all of those doping sticks? Or how do you do transfer the bigger ones?

    • @mikesackos2208
      @mikesackos2208 2 роки тому +1

      For large stones, one of the transfer fixtures from Ultra Tec won't work, I have to use the other fixture I got from Ultra Tec, because the maximum distance between the dops in one transfer fixtures does not leave enough space for larger stones. For really large stones, I use my 3rd Transfer Fixture which can pretty much accommodate rough thicker (deeper) than anything I have ever tried to cut, so far.
