Anyone using the Tormach style TTS tooling system on a Bridgeport??
Just looking for more repeatability in tool mounting but unsure if the TTS system is a good match for a Bridgeport.
Thanks

Thats good to know, thanks
I'm using R8 ER32 chucks at present but being they are made by different companies, they all seat slightly off so repeatability is not 100%. I think the TTS is a way forwards, even with cheaper toolholder makes due to the way it locates on the nose.

There is also the notion of using a straight-shank holder with a nose ring fitted to convert into a TTS style holder, Tormach even sell a conversion kit with the ring and epoxy to fix it.
Is ER32 the way or will ER20 be up to the job? I'm not sure ER20 has enough bite on the tool shank.

Obviously i might have to shorten the latter one as you cant fit a 100mm shank into an R8 collet :)
The main reason for asking is that I think the first one is too short at 35mm shank???

I'm asking this out of ignorance - is the R8 taper and the accuracy of the shank of these tools good enough to define the position of the shank in the collet repeatably? I guess it is, it's just that because there doesn't seem to be a hard stop to set how far the "adaptor" shank goes in it doesn't feel quite right to me. I need to do the CNC conversion of my mill before I start thinking about powered drawbars and things, but the price of these things does make it look a practical proposition.
