Just think if you would have bought advertising. You should have saw the opportunity that they were about to create for you by giving bad advice to people that would mess up their throttle bodies that you are in the business of repairing. You would have to hire guys to work for you to fix all the throttle bodies. I think that show was tailor made for you to advertise on. My step bit actually has deep steps so the step tha was the diamter of the hole served as kind of a pilot for the next larger step so maybe thats how i got lucky. I taped it (not tapped, taped with tape) to make it fit snug in the bore and went real slow with a t handle by hand. That aluminum is so soft it didnt take much.
I take great pride in doing things right the first time, so I'm not the first bit interested in being part of a TV show that shows folks some half ars way to accomplish a precise operation. In addition, what kind of person would that make me if I got involved with that show and let it happen knowing full well that I could/would profit from it later? The problem with your bushing install method is that it is IMPOSSIBLE to follow the exact path of the bore without a "lead" that extends well into the center section of the carburetor. Any sort of cutter with only one cutting surface, is a BAD idea right to start with, if one intends to bore a hole in something with any sort of accuracy. Think about the physics involved with boring a hole or holes into anything that requires them to be on center, and you will quickly realize the risk(s) involved with a one or two sided cutter boring into a blind hole without some sort of support on BOTH sides of the cutting surface. Cripe, I don't even like turning steel parts in the lathe, even when they have a LOT of integrity to them, without using a live center on the free end. Enough of the scientifics, and my intent here is NOT to be critical of the efforts of others, or drum up business, etc. Bottom line with this particular topic, IF you don't use a tapered reamer or self guided cutter of some sort, fully expect LESS THAN DESIREABLE RESULTS!.....Cliff
