Quick change tool post

[thaiguzziParticipant @thaiguzzi]

Bison – Dickson copy.

1 in the toolpost. 1 spare on the lower shelf. 20 ready to go on the top shelf. 22 in total. No more!!!

Original Boxford indexing 4 way toolpost on the lower shelf used only for clocks and DTI's, always on CH.

No more? I thought that with 6, then 8, now 20 for me!

If I'm honest I'd spend the £82 towards some decent collets and spindle mounted chuck. It will give far more accurate results in turning operations than using a 3jaw or 4jaw and save a lot of time too. I stand by what I said in my previous post, (rightly or wrongly), if your just starting out then all the other gimmicks of tooling can be looked at in the future, a single tool post holder..

You know what, i'm inclined to agree with that sentiment, I love QCTP's and I would never go back, but to begin with I did just use a four way post with tin can shims and off cuts underneath them.

Still, good to keep the aspiration to a Dickson type or whatever floats. They are definitely worthwhile. It isn't worth throwing out the idea just because it can't be done immediately.

It's a relatively simple modification to make a new T clamping bolt to the right length and handle to suit. The only thing I would keep an eye on would be the length of travel on the adjuster height screw, relative to the height of the lathe ofc.

It was good to hear from someone who has used both the Dickson and GHT fourway toolposts. I have no experience of the former but the change between the four tools on the GHT is virtually instantaneous. One of these days I will do a proper test to see whether the repeatability of mine is anything like the impressive results he achieved.

One of GHT's reasons for favouring the fourway over the QCTP was that in his day he found that few QCTP users had the large number of holders which is common in these more affluent times.
