Tool Platform to C/L distance on an ML7

[Andrew TinsleyParticipant @andrewtinsley63637]

Can anyone tell me the height from the top slide tool post area to the lathe centre line on an ML7?

My ML7 is in bits and I want to know what is the maximum tool size I can get into a Dickson type toolholder, hence I need to know the above dimension.

Many Thanks,

Andrew.

Hi there, Andrew,

I posted this in another thread only a few days ago:

It's from G.H.Thomas' book, details given in the earlier post.

Did you solve your lead-screw problem?

Best regards,

Also check the thickness of the bottom of your tool holders as they can vary depending on the source of the "dickson type" post

Great bit of info, is it the same for a Super 7?

The diagram shows the dimensions GHT measured on his machine. They are, of course, subject to manufacturing tolerances and hence vary slightly from machine to machine.  GHT recommended that ML7 (and, by implication, Super 7) owners should measure and record the specific dimensions of their own lathes and keep a copy for future reference. Mine is laminated and pinned to the wall behind the lathe – I also have another in my 'study'.

By the way, the tool-post shown in the diagram is the Myford four-way tool-post.

I reckon the original diagram was dimensioned using a Uno stencil & pens – anyone remember those?

Best regards,

Swarf, Mostly!

Thanks Swarf!

Just what I needed! Yes a 1 metre length of leadscrew is on its way. So, including new bushes, it will have cost me under £100.

Hello Jason, bottom of the holder already measured and factored in! The base to centre line height is 0.666" and thickness of the bottom of the Dickson holder is 0.230". This will give me a maximum tool size of 0.434" or just a touch over 11mm.

With the same type of Dickson tool holder, I can only just squeeze in an 8 x 8mm tool on my ML10!

Thanks everyone,

Andrew.
