    SAA Work Holding Question

    One of the first things I was taught in jelwery school was that there were no substitutes for Ruby Stones. I have one in my jewlery bench and one at both of my engraving benches...they have all been with me since the late 60's.

    SAA Work Holding Question

    I do recall Frank's seminar and what he said about sharpening...dubbing was an after-thought of his demonstration. He gave a a quick sharpening demo during the first FEGA Seminar - this was 1984 +- and many years before the advent of any manufactured sharpening device. Like most engravers of...

    SAA Work Holding Question

    Yes Marty, but we are relics of the art. The 105 is finding favor with lots of folks, it's a good medium V graver with lots of good attributes. Still, when I really need to get into really hard and resistant metals, the 120 is my go-to graver....and dubbing makes it even better.

    Dubbing is not graver geometry specific, it works (stengthens the cutting point) on all V and onglette shaped gravers.

    Bulldozer

    It's a commercial sharpening guide for grinding/forming the dubbed face. I don't sell the Otto Carter Bulldozer Fixture, but I use it - look it up for yourself.

    SAA Work Holding Question

    I recently had to engrave a Model 70m Winchester action for a John Bolliger Custom .470. I really had a great opportunity to test traditional dubbing to the Bulldozer. The differences were dramatic in the way the Bulldozer cut the kind of deep lines and gold inlay channels I needed in the...

    SAA Work Holding Question

    It's a very precise and delicate little operation - Frank Hendricks talked about it when he presented the very first FEGA Seminar back in 1984. He was taught to "dub" his point by the Germans. Yes, "dubbing" is a strange term, but so was "Speitzer." That's what he called his graver...

    SAA Work Holding Question

    Because of the way this special "Bulldozer" geometry strengthens the graver. Bulldozer is the term phrased by its creator, Otto Carter. It's a simple but enlightening expansion on the old practice of "dubbing" the point. As I described earlier, the entire cutting edge (at the face) of the...

    SAA Work Holding Question

    It is a sharpening method that creates a "dubbed" cutting plane along the full length of the face.

    SAA Work Holding Question

    Yes, although there are some differences in the hardness for the stainless and blued steel models, the loading gates and hammers are really hard to work on either. I use Otto Carter's "Bulldozer" sharpening jig for all these hard parts - it helps a lot!

    SAA Work Holding Question

    These fixtures will work for some of the Vacquero parts: the frames, the barrel, the ejector tube, the hammer and the screws. They will not hold the Vacquero trigger guard and backstrap. The issue is that the Colt is built with separate trigger guards and backstraps - the Vacquero is a one...

    SAA Work Holding Question

    I worked directly with GRS to design the set of Colt SAA Fixtures that they manufacture and market. These are a result of many years of experimentation with the available fixtures starting in about 1975 - some of which are show in this thread. There were several individuals making and/or...

    Question: 901 air tac handpiece modification

    I have been using my 901 as came from the GRS Shop in about 2002. DJ Glaser brought his 901 trial model to the FEGA Show at the Silver Legacy in Reno, NV to show us his new ideas about hand pieces - it was unlike anything we had seen before. I placed my order - and many others did as well -...

    Three Colts

    I'm just getting into a set of three Custom Shop Colts SSA's - these are 2nd Generation .45's with three different barrel lengths, matching ivories, and consecutive serial numbers. The subject Theme is set by the client following Wyatt Earp, Doc Holliday and "The Cowboys." Given the "Hollywood...

    Colt Cylinder

    I did consider that, but these will be cased with the two others and having the 2 scrolled flutes, one under the frame top and the other facing the bottom of the frame, it made little sense to incude the Jokers there. There are three guns, three different barrel lengths and with consecutive...
