OK Mr Qjet, consider this strike 2 and your first warning.
Going back and digging up old threads to make a point and throwing a few stones in my direction isn't winning any points for you on this Forum.
Feel free to respond to CURRENT threads with useable and accurate information, but taking a stab at me personally isn't going to be tolerated here.
You were much kinder in this thread than the first one, but I am NOT going to tolerate any digging up of old threads and making any negative comments toward myself or anyone else at any level......understood?
We have worked on many thousands of q-jets (went over 7000 last year) since going full time in this business in 2003. I certainly know how to address any issues with warped main castings and air horns. We have next to zero issues in that area and most don't need anything when it comes to this topic. You will find gently warped main castings and air horns, and 99 percent of the time they warp at the same rate across the front and seal up just fine without any additional help. If/when we run into fitment issues between those parts there are less intrusive ways to correct that issue than subjecting the parts to an unwarping process.
I'm not saying here that your tool doesn't work, or anything of the sort. I am saying that for most of the carburetors we get in here subjecting them to that process isn't needed for a perfect end result.
As for the bushing install system that you sent us I don't use that method, my set-up is superior in every respect and insures that the bushings are in perfect alignment with the original bore thru the front of the throttle body.
In other words I much prefer using a cutter that guides itself through the bore rather than trying to use a drill press and counting on a two fluted bit to stay on center and follow the original bore even if we have it well lined up. Due to the angle put on factory drill bits they can chatter, wobble, go out of round and not follow the original bore exactly.
To date I've installed many thousands of bushings into Q-jet throttle bodies with one of the very first drill bits that I made back in the early 1980's. Haven't even touched it up and it still bores a PERFECT hole DIRECTLY on center every single time.
Using our tool you don't need a drill press or a shop vise. The user can lay the throttle body flat on the work bench and bore the hole for the bushings with a hand held drill right on center every single time. This happens because the long lead not only aligns the cutting edges in the center of the hole, it provides support for the drill bit and doesn't allow it to chatter, walk off center, or bore a hole that's to big to effectively hold the bushing or "egg" shape the hole during the drilling process.
Anyhow, enough on unwarping and bushing installation....and minding our manners when it comes to posting here.......Cliff
