quick change tool post
morning,
has anyone out there successfully fitted a quickchange toolpost to a colchester triumph mk1? indeed, has anyone got any hot tips on selecting and fitting new quickchange toolposts? all i can find are so-so chinese units, there must be something worthy of this old girl. cheers, nic
what's the catch with the CDCO gear? they're so cheap but look the part, any bad news stories using their stuff?

hi nic
i recently fitted a salvaged qctp to my master round head. it was from a lathe going to scrap.
i had to bore the tool post out a fair bit which was a real pain because it was very hard. http://www.woodworkforums.com/attachments/f65/184771d1318828415-todays-tools-gloat-img_0288.jpg.

Last I looked CDCO only sold the piston type. Wedge type is generally considered better. I bought a CXA chinese wedge type from a US ebay seller and ten holders from CDCO. Both are underwhelming. The holders have generous tolerances on the dovetails. I had to put a shim behind the wedge on the post to get most of them to tighten up at all. If I were doing it again I would look out for a used Aloris on US ebay and make my own holders.

I have bought my two Aloris clone holders from Quality Machine Tools in the US..... The quality of the tool post and holders was good except for the grub screws in the holders... They are softer then butter and I hade to replace the screws with new ones...
Gold, the colour of choice for the discerning person.

I second Bryan's thoughts on a Secondhand Aloris from the US. Aloris will ship spares to Oz, so new screws/ nuts are not a problem.

If you feel that they would be suitable for your intended purpose,you would then have to either except them to use or purchase an original Aloris toolpost and holders.
There appear to be quite a few people on this forum that have this style of holder with mixed opoinions,some have the piston type and others the dovetail type.
Maybe if you ask the question how people find their particular style works would be beneficial in your decision making.
Do you at this stage know what size toolpost your will need.

thanks pipeclay. i am set on the wedge type toolpost because it holds better than a piston type. as for sizing, CXA or CA sizes will suit my 7 1/2" centre height and my preference would be for the larger CA model. i'd still like to hear what people thought of the chinese made wedge types.
