Orifice gauges, what do you recommend?
« on: January 30, 2025, 09:28:31 AM »
  I would like to get a decent set of gauges/ tools for measuring the various orifices in the Quadrajet, what do you recommend to use?

 I've been using various kinds of tools and wire so far, but I'm afraid my accuracy is suspect.  I am using welding/ cutting tip cleaners that I've labeled with the sizes since they have 2 different diameters, but they are not close enough in size from one to the next. I also have a large set of transfer punches that start at about  .040" and go up in increments of a few thousandths each. But even with these it leaves a lot of guessing as to exact sizes.

 What is available for a decent price that would work for this?
 And where would I be able to get a good set of micro drill bits for doing this kind of stuff?

 Great, thanks for the link, those look like what I need. I'd rather pay a bit more and get an American made tool I know I can trust.
 Years ago I had bought a small set of tiny drill bits at a tool show that were made offshore. I could do better with the lead from a number 2 pencil. The only thing that lasted any length of time was the metal case the sorry things came in.
