I've had limited success with Ardublock in a training environment. Are you familiar with ladder logic and PLC programming? If so, Soapbox SNAP might be more suitable for your needs.

Hi Rob

As Ian has suggested, Paul McWorter is to be recommended. He's a professional teacher & trainer which makes all the difference. I can also highly recommend Peter Dalmaris over at udemy.com:

For a (very) few £/€/$ you get 23 hours of video instruction, handouts, and support. I think it offers amazing value for money.

Starter kits are convenient, but not always good value.If you're comfortable with a soldering iron and veroboard you don't have to spend very much at all.

Thank you Neil, that advice is spot on. I discovered that the technique is to gently tighten the ring until it is "just" possible to move the lever fully to the left (it feels just like an over-centre cam action). The cutter is released by moving the lever to the right.

I was tightening the ring too much by hand which ironically meant that the collet was never gripping the cutter fully. Most of the collets have no markings at all, a few are marked Hardinge. Some are clearly well used, so a new set may be in my future!

Thank you all for the very helpul responses. As suggested, I removed the capscrew (it was only finger tight) and fitted the stay in its place:

However...

The chuck doesn't hold the cutter very firmly. Tightening the chuck by hand as much as I can (gripping the ring with an old towel) the cutter pushes back into the collet even whentaking a light cut on some aluminium. I tried various cutter and collet combinations. I assumed that the purpose of the handle is to release the cutter, but when I tighten the chuck up as far as it will go, there's very little movement in the handle.

What am I doing wrong?

Hello to all

I'm new to model engineering and still fumbling my way around. In my small workshop I have a Myford S7, an old CAV round-bed lathe, and a pillar drill together with a reasonable stcok of hand tools. My workshop also accomodates my electronics bench and sometimes it's a battle to keep the swarf and shavings out of the live bits!

Looking forward to getting stuck in.

Hello to all

I've recently purchased my first (new to me) Myford S7 lathe together with a very comprehensive kit of accessories. Setting up the vertical milling slide was straighforward, but when it came to fitting the collet chuck, I ran into a snag. There's an articulated stay on the side opposite the handle which has a threaded section and a locking nut. I can't see where this should attach to the lathe itself.

It's no doubt obvious to anyone who's ever used one, but not to me! Can anyone point me at a copy of the instructions for this chuck?
