Hi, I bought a Myford ML7 a few months back and have only just got around to setting it up properly ready for my first project, anyway I needed lathe tools so checked in the owners manual and it says 10mm tools, went to Arc Euro trade and bought myself a 8pc set which I thought would get me started if nothing else. Fitted one into the 4-way tool post to find the cutting edge is way above centre, am I able to drop the height? Admittedly I only had a quick look and couldn't see anything obvious, any help would be extremely grateful.

Thanks

Mark

You need 8mm shank tools.

Might be a bit late to send back the ML7.

Interesting, I just found an old ML7 manual on line and I couldn't see anything in it about tool sizes (or even any advice on how to actually USE the machine.

This little excerpt was amusing, given how some people complain about having to remove preservative grease from Chinese lathes...

Just remembered it wasn't in the user manual I found it, it was actually on this forum, but when I just went back and re-read the thread it's referring to a Dickson tool post/ tool holders. But hopefully I can get them exchanged as they are unused and I only received them today and if not its about £20 to rectify the mistake, could be worse

Give Ketan an email/phone. If they are unused I'm sure he'll exchange them for the right ones.

Mark,

The original Myford 4-way tool post was designed to take 5/16" square tools, which these days means 8mm square.

I have one of the tool positions milled out to take 10mm on my 4-way.

As you realised, with a QCTP you can go up to 10mm

Thanks Robbo, I'll try and get my erroneous purchase changed tomorrow for the 8mm variant, if that doesn't work I'll throw the tool post in my milling machine and take a couple of mil of it 😉

Hi Mark,

Or do what I did when I inherited some 10mm TCT tools. Set them up up in the milling machine and take a bit off the bottom of the tool to get the correct height! Mind you, the steel is bl**dy tough to machine. Since buying a Dickson QCTP for the S7 it makes life so much easier.

If you have a vertical slide it's generally possible to mill them down in the lathe. I did lots in a Taig so am sure an ML7 or others could cope.

It's ok I'm getting them exchanged. A very nice man called Ian from Arc Euro Trade read this thread and phoned me out of the blue this morning to say an exchange was no problem, this is the kind of customer service every company should have and will certainly guarantee I use them in the future. Thanks Ian and Arc Euro Trade!!

You can't get better service than that Mark. If your tool post is like mine, you would be pushing your luck trying to machine it down to fit, hard as!!

FWIW, make up a Centre Height Gauge. It will save LOTS of time setting tools to centre height.

Just shim/adjust the tool until it touches the underside of the blade (which has been set to centre height), and you are ready to go.

Why not just reset the height gauge you used to measure the centre height? Saves even more time.

Good customer service ? Second nature to Ketan and his merry crew !

This is my setting gauge. I only use it on the tangential tool as I've epoxied or screwed shim plates to my insert and parting tools so they're permanently on centre height.
