Sort of... I borrowed a Swiss Multifix from a friend (he was going on holiday and didn't need it for a couple of weeks!) to try it out on my Connoisseur, then subsequently bought a clone from Rotagrip. Size A.
If you intend to sit it atop a Myford top slide, I think you would be wasting your money, as you wouldn't gain many of the advantages it has over a Dickson. Also, you're supposed to fit dowel pins through the Multifix into whatever it sits on, to accurately position it and prevent it from twisting on its securing bolt - I think that might be inadvisable with a Myford top slide, it's weak enough as it is, without drilling more holes in it.
The A size is too big for the topslide, it's not possible get even an 8mm tool low enough to get it to centre height, you would have to order the Aa size, of which I have no experience.
However... if you have a DRO fitted and don't need the topslide for most work, then a size A Multifix can be mounted directly to the cross slide via an adaptor plate - I'd say go for it, it is better than the Dickson. And as it happens, I've designed an adaptor plate, the cast iron for which is currently on the milling machine being carved to shape! It should be finished next week.
Disadvantages of the Multifix over the Dickson: 1) the cost of the tool holders - they're something like twice the price, 2) for the size A the 1675 holders are 25mm longer, so you loose 12.5 mm of space between the front and rear tool posts, and 3) for 10mm tool overhang tools must be at least 50mm long as the holders only have 3 bolts spread over their 75mm width, preferably 85mm to get a tool clamped by all three bolts.

I have used a Multifix Aa on my Myford Super 7. It's the right height and the holders are a good length. The size of the toolpost is fine for light work, but slightly on the small size for anything requiring a bit more eg deeper cuts , bigger threads. It had a very nice parting holder that worked a treat. Size A is too big, something in between would be better.
At the time you could only get very expensive toolholders , - now eg I see they are £37 from Rotagrip, so I sold it.

I have an Aa size Multifix fitted to my Boxford - a little bit too small really but it works very well and I have never suffered with it twisting on the mounting bolt - I don't have any dowel pins fitted. Mine is a genuine Multifix, rather than a modern copy.
I'm hoping to get a larger one for my Harrison at some time in the future, and I was thinking of getting it from pewetools in Germany **LINK**
I'd be interested to know how you get on with ordering from Create, particularly the import charges and the delivery times.

I use an A size on my 5 1/2" x 30 lathe. I bought it second hand. An original multifix (swiss made) tool post with an assortment of tool holders, some swiss, some west gerrman, some german, some french and some chinese. Their is a fair bit of commentary around the internet that recommends to get a swiss or german tool post and then source from wherever you get chance for the tool holders. I am not aware that the create make either the internal or external screw cutting tool holders although they do make blanks which I like.
I don't have a myford but I have seen them and I couldn't imagine the A size being the right size. Aa is the correct choice. It can be confusing to find the country of origin of the various compatible offers. Don't quote me but here are my thoughts:
Create, Pewe tools are chinese made. The create A size parting tool holders are rubbish as they don't hold the blade at the correct angle. The regular AD are ok but the corners of the tool holder are not relieved.
Amestra ("original" multifix) french made. i have some of the Amestra AJ bar holders. Really nice up their with the German.
Original Swiss made all have swiss or suisse on them and are everything they need to be.
AXA (German) are very nice and available from amazon.de.
For all these I suggest keeping an eye on ebay.de.

The only claim I have heard for them which was from Schaublin users is repeat tool positioning - take it off and put it back in exactly the same place. That might be good for repetition work. As they lacked the location I can't see that the lack of slip comment that they also mentioned is valid.

So did you bore the top bushing to fit the Myford mounting bolt? I am warming up to the Multifix as I only have two holders for my Dickson. I would have to make more but it is tedious. I live in the U.S. So Myford specific tooling is harder to come by.
Thanks for the replies
