HOME MADE LATHE QCTP
Arbalist:
Dickson's are not only well made from quality materials but they are a well designed product proven in industry. The Tool holder is pulled into the tool post when they are locked and turning adds additional pressure. The OP's design appears to push the tool holder away from the bulk of the post when you lock it. Tool pressure is then opposed by the locking mechanism, not a good idea. You should have looked at Bison Jon, fully compatible with Dickson but at a more affordable price for small outfits on a tight budget.
Jonny:
I use two Bison chucks pretty good, ones 19 years old the other 15.
Knew there was some knock off Dickson around 3 or 4 years ago but already had above tool posts and tool holders.
Just had a look at the Bison £281.75 plus tool holders £76.25 each = £2012.25. BXA knocked me £430 19 holders and 5 tool posts, gave three away.
GRIFFIN:
Hi all,
In fairness I'd have to agree that there is probably no comparison between my self designed, home made QCTP and one of the aforementioned monsters costing hundreds or even thousands of pounds for a tool post and handful of holders. However I think the materials cost me about 45 quid, I used tooling I already owned and had a whole hell of a lot of fun drawing and making my own. Now at least when I want to change tools it doesn't take me ten minutes to find or make spacers and shims just to get on centre.
I didn't throw away my four poster either, so if rigidity is ever a problem with my sub standard home made QCTP (which I must say, "it never has been") I can always use the old one.
Joking aside though, I'm proud to have made my own rather than having bought one, no matter what the cost and if everyone just went out and bought stuff off the shelf, Mad Modder wouldn't exist, would it?
Cheers, Griff.

Thanks for sending the drawings Griff, a very practical design.
