I had one on my new CHCNC TK mill. Its ok, and I might have really liked it on something like a Bridgeport manual mill, but the single source for tool kind of bugged me as did the price as compared to other R8 tooling. I removed it. For now I am running a Kwik 200 master holder since I already had a bunch of Kwik 200 tool holders. Now I can actually use pre measured tools and use the tool table. I may switch to a TTS stle system in the future, but for now the Kwik 200 stuff serves my needs.
Anyway, I don't plan to use the Mach 1 system on anything I have now. I ws thinking about using it on my manual mill, but I got a deal on a second Kwik 200 master holder for it, and I am going just box up the Mach 1 System. I have several R8 collets with the Mach 1 pull stud, 4 collars for collets, 3 tool holders, and a couple other things. I'll sell them (as a lot) for 60% of what new ones cost from Mach 1. If nobody here is interested, I'll put them on Ebay. If somebody buys the lot I'll throw in the cap and drawbar assembley, and tool holding fixture and collar wrench all together.
Its a really neat idea, and I think some people will like it, but its just not for me. I hope that somebody who likes it will snatch mine up and save some money on extra tool holders so they can be more efficient.
I put this here in the Charter Oak board first becaue Charter Oak offers the system as an option on their mills, and I figured one of you guys might be using it. I'll post in the classifieds later, and if I don't get any interest it will go on Ebay sometime next week.
