Epoxy makes a great dopping tool. However when it is neccessary to transfer it is a bear. Here is a trick. Take your dop, wax the end and while it is still warm form it on the end of a plastic crutch tip. This will make a flat grooved point to index from. Take the stone to be cut and use two hour epoxy. Place epoxy on the stone, and the dop where the wax is flat. Transferring now is fairly simple, within the simplicity that can be had from transferring. Transferring, just heat the dop to be transferred, the heating will allow the stone to accept the wax and attach to the transfer dop. The first dop can then be heated and the wax will soften. The epoxy is ground down with the cuts. The epoxy allows fragile stones to be dopped and transferred without destroying their treatments. Emeralds, oiling an example. Heating the stone to be dopped will burn the oil. Usually Linseed oil, or Canadian Balsam. Try it, you will like it.

good advice
and thanks for answering my query about buying faceting rough in the SF bay area in the General area of this forum
Yep, I just got a used Graves Mark 1 facting machine, with about 20 laps, preformer with motor, tons of dops, etc. - the works
I know the Graves is not the best machine, but at least it is a place to start - who knows, maybe an Ultra-Tec or Facette machine someday, if I like cutting??
and yep, Caveat Emptor is the name of the facet rough buying game, but I am in it for the fun of it - I m going to start faceting with some quartz, amethyst, even leaded glass, cheap stuff - and if I get decent at cutting those facets, I may move up to some cheap man-made sapphire even though hardness is 9, or maybe even some real sapphire/tourmaline/topaz, etc. if I can afford it someday

Write me on Send a Message and I can walk you through faceting. It is easier than it would seem. The most important point, 96/48 is width. 24/72 is length. Corners are 6 points either way of either. That works for pavillion and crown. You can make a basic gem with that formula. Graves might not be the best but, it has made some awsome gems. It is not the machine. Give yourself time and lots of throwaway gems. Saphire is ok to start if it is small. A large 9 mohs and you will tear up your lap.
