I realise I'm going over old ground with this request, but could anyone recommend a good quick change tool post/tool holder system for my ML7. Looking through the ME archive I've found reference to 'A & R Precision' QCTH who, on the face of it have gone into liquidation.

There seems to be quite a few to choose from internet wise, including some of which that don't have a very favourable write-up (in the archive).

I & many others have been on this ‘journey’, although I had no problem using the original Dixon manufactured tool post in industry for many years the far eastern clones on offer today are not made to the same high standard & this can cause operational problems.

For that reason I recently sold my collection of little used Dixon type QCTP & holders & changed over to the Arc Euro trade wedge style lathe tool holding system.

As it uses a different type of clamping system any minor size differences from holder to holder do not affect the clamping strength.

Obviously others will have different stories to tell.smiley

Out of interest Tony, which size did you choose? The 000 is ideal for mini lathes, is it a good match for a Myford too? The 100/111 seem a bit OTT for a 3 1/2" lathe.

Must be the 000, according the Arc Euro site? Ketan seems to offer an 'adaptor' kit to replace the toolpost pin etc on a Myford for this size....

Cheers, Colin

As Tony says the Dickson system has been undermined by poor quality copies from some Asian manufacturers. The spacing of the V guides is critical and the relationship of the tee slot for the clamp and the V has to be held to tight tolerance or the holder will not lock and stay locked. There is something of a range of prices and you would hope the more expensive clones would be ok but it may be better to look elsewhere especially as most people build their toolholder collection incrementally over time and getting ones that fit may not be straightforward.

Hi Guys,

I've just made a "Norman patent toolholder for my Myford S7B. I should have done this years ago.

No modifications to the lathe, just removing the old tool holder and replacing it with a 38 mm diameter post. I also made a new nut to get rid of the ball handle.

Yes it's the 000 size I'm using. Multifix & it's clones looks good but they aren't cheap.

Might pay you to drop me a copy of the article then !

I have a complete set of drawings based on the original patent. Though I have published my design in a number of places.
