Re: Super Fly Alternative - Review
Since I pitched the ATC the lack of groove is no big deal, but again... if you have a lathe you can make one. I've made several complete tool holders now on my lathe and use them all the time. TC tappers, endmill holders, long reach end mill holders etc. I've also used the Tormach press on collars to convert some tools to TTS style. My TC tappers aren't so perfect because I made them a little sloppy on purpose, but I get sub half thou runout without trying to hard on the rest. Drill, bore, ream. Do everything important in one setup or use the 4 jaw (or now the SetTru). Balancing on a set of parallels on the granite plate (I do that for surface grinding wheels) is an option, but so far it hasn't really been needed. Not at Tomach 1100S3 speeds. Now on the little 24K machines I only use factory collet chuck tool holders.
I almost forgot... I have also used the collars on a couple shop made tool holders just for speed and expediency. I keep a couple on hand just in case I need to make something quick.
