Buying a quick change tool post – Which one?

[mgnbukParticipant @mgnbuk]

Maybe the Emco clamping design was to get around patents for the cam locking device ? Or cheaper / easier to make ?

For all the naysayers denigrating them I can’t say I have had any issues with Dickson toolposts, either at work (Harrison M300 / Harrison VS330 / Colchester something-or-other / Harrison Alpha 400) or at home (Myford S7 / Warco GH600). The kit I fitted to the S7 came from Myford’s Spares Counter (with the “W” marking) – subsequently purchased holders from RDG and all fit & lock up without issue. The GH600 post came from Ebay & is of Indian origin. Seems well made and is certainly hard – I had to bore out the base to fit over a cast-in boss on the compound slide & it put up a good fight. All the holders I have (which appear to come from a number of manufacturers) fit and lock up without issue.

Couldn’t use a wedge-style TP on the GH600 as not enough material in the TP base to bore out to fit over the compound slide boss & the compound slide is not really thick enough to leave sufficient thread engagement for the clamp stud with the boss milled off.

“Which tool post” discussions seem to be akin to oil threads on motorcycle or car forums – regularly discussed & respondents all have their favorites.
