Will AXA toolpost fit on a Myford Super 7

[Russ BParticipant @russb]

I'm not sure if I'm mistaken or not, I'm asking searching questions here – so any related info or tips, especially first hand advice would be great

I'm looking to purchase a quick change tool post for my Super 7, and I fancy a Dorian AXA size wedge type from MSCdirect. I have read through and I see that the minimum centre height from topslide is 0.875". Regards fitting an AXA size post to a Super 7 – from memory I think they are about 0.650" – am I mistaken?

This would mean losing 0.225" off the maximum tool height of either 1/2 or 3/4" (conflicting information online?). If this is 1/2", it would leave me with a meagre 0.275" – restricting me to 1/4" tooling or forcing me to grind away a little from the tool holder to perhaps squeeze 5/16" in?

p.s. Regarding the non standard 60% size version of the AXA know as the 0XA – I can't find a European supplier but I'll keep looking – they seem more suitable although perhaps questionable quality…… Tormach seem to make them for LMS in the states.

I wish the powers that be would revise the standard and release a 0XA officially!

0.655in on my S7.

What's wrong with a Dickson toolpost?

If you could link just to the item you want to show that would be good. Your link above is to download the whole catalogue – zillions of bytes!

Yes it's 20mb sorry – sadly they don't offer information any other way – but it's a nice read =)

I know the Dickson tool post's offer a high quality time proven solution but I prefer the expanding tapered gib of the wedge type tool posts, combined with the tool less operation but I guess that handle could get in the way

although a lot more complicated – It just seems like a better system ** for the benefit of anyone not familiar** rather than pushing or pulling a dovetail together the wedge type expands the dovetail and pulls the tool holder down against its level screw while expanding the dovetail and then pulling the tool holder flat against the face of the tool post. It's not a simple system you'd have to read page 29 of the brochure to see how it's all working together to provide that result.

The Dickson type likely offers more rigidity than that of the top slide sooo……. the weakest link could be argued – maybe I just fancy something different – plus the Dickson Tool Holder are very expensive for such a simple design.

I can import a 0XA from LMS for around £130 with vat and shipping fees (should be free of duty as its under the limit) it comes with something like 5 holders I think!! – There is cheap, and then there is TOO cheap….. I'd rather pay £200+ and get something made with a little more love……

Well it's quiet in here……..

For the benefit of anyone reading this in the future – possibly a beginner like myself, use Google to search model-engineer.co.uk and not the built in search box, or you'll find, as I did – you get very few results – where as google does some magic and searches deeper and may find someone mentioning something that is not in the title of the thread but may be relevant – and may have only been discussed less than a month ago – thus the members here are probably dishing out the silent treatment…..

The AXA (I think) is known as Type 100 in Europe, so searching for both could get you more results.

To conclude – an AXA toolpost will not fit without to much compromise or modification – personal opinion, just leave it alone unless your looking for a "quick" tool post that cost's you a fair amount of time, the 0XA are likely a great option, BUT….

As has been pointing out privately, the fact that "everyone" has the Dickson, (or Dixon) type, T00 means that holders are available 2nd hand from time, as well as from many other suppliers. Obvious I know, but I overlooked the benefits of being able to pick up extra holders.

Also the T00 are not so much a direct fit, as the bore on some is not spot on – Bison make the T00.B and T00.M – the M, possibly meaning Myford has a 7/16" bore and a lower overall body height, making it more suitable for the Myford, (as opposed to the B for Boxford?)

A and R Precision make the Dickson style T00 tool post, and all it's accessories they trade on eBay and go by the name of aandrprecisionltd **LINK**. I think they come complete with an adapter for the 7/16" bore if required – worth checking – they used to make these for Myford before they were liquidated in 2011 so they are the real deal, made right here in the UK.

Norman,
Looks like I'm going to be getting a Dickson type after all

Russ,

Just for info. … There is a convenient "shortcut version" of the Google search available on the home-page of this site.
