Grinding chuck jaws

Hi all,
Towards the bottom of this page http://homemetalshopclub.org/news/aug04/aug04.html is an article on grinding chuch jaws. The method seems to make some sort of sense.
I have a Toledo TCT 15 Combimachine grinder (struggling to find any decent images, but look here http://www.wowowo.co.uk/top_products/5292/5292-30.htm about a 1/3rd way down).
I need to somehow mount the grinder to my lathe in order to grind the jaws. My lathe is a boxford cud (4.5" center height). If I were to stick the grinder direct onto my compound slide (replace the toolpost), it will be about center height, but as the case is plastic and no flats on it, I am not sure how I would mount it.
Looking for ideas (or if anyone has done something similar, perhaps some photos).
On another note, when I can get it mounted, no doubt I could do cylindrical grinding... (I used to be a trained grinder before I joined the airforce). I would prefer to dress the wheel prior to grinding. I have a diamond dresser, any ideas how I would mount it in order to dress my wheel parallel?
Thanks.

If its a dremel clone, which from the piture it looks like then a couple of big hose clamps round the body securing a bar which can be clamped in the toolpost would do it As for dressing a wheel magnetic stand on lathe ways with dresser clamper to post, move carriage back and forward, use cross slide to alter DOC?

Some "Milliput" or something similar can be moulded onto your grinder body to hold the bar steadier. Some clingfilm will stop it sticking. All clamped as above.

It is like a dremel, but much bigger. (I used to have a smaller one, but it somehow disappeared. It did have flats on that one that I could have clamped to).
Good idea re the hose clamps. Never thought of that. I was thinking of somehow making like a bridge type of clamp, but I think that would have been unstable. Hose clamps sounds like a much better idea and quicker to implement as well.
Also, good idea re the mag mounting of the diamond dresser.

Here is my die-grinder toolholder, which I made initially for the purpose of de-bellmouthing some chuck jaws, its prolly a bit OTT, as is my usual way. Light alloy was what I had to hand at the time:

Incidentally, the chuck is a lot better for it.

Yes, I was thinking I may have had to make something like that, but I thought for all I am doing, it probably is a bit OTT. I just wanted something quick (and efficient) just so that I can get on with building my engine...
Perhaps when I eventually turn my lathe into a pseudo cylindrical grinder, I will go to a bit more length for something like this. However, it may be worth me getting an air grinder.
Thanks.

Is that the Ferm combi-tool thingy?
If so then the plastic bit next to the chuck unscrews, and you can mount the tool in something vertical with (I think, but check) an 18 x 1.5 mm threaded hole.
The 18 x 1.5 mm thread seems common to many such tools, including Dremels and most dremeloids.

Hi Peter,
Yes, it is like that ferm combi tool. (Mine has Toledo tct15 on it, which is what I wrote, but it looks like they are the same). Yes, I did notice the nose has a thread on it (didn't know what it was... thanks for clarifying). I would have thought though that just supporting on the nose wouldn't be enough as there is all the weight of the body the other side.
However, if I combine that idea with Charles' idea when I come to make a more permanent mounting for it, it could be a good method for location.

The threaded nose is intended for mounting the drill in a vertical stand, which it does quite well - but a horizontal mounting may well need some extra support at the back end.
Also the m18 x 1.5 thread was originally chosen for a Dremel, which is smaller and lighter.

Ah, right. I wasn't aware of that... Makes sense. For a horizontal mount, it would not have been suitable.

Well, I have gone and done it now. Ground them up.
I was surprised as to how much I had to take off to clean them up thoroughly.
I marked each jaw with black marker then ground them. The first strikes were at the rear of the jaw and I set my dial index. By the time I had cleaned all 3 jaws, I had taken about 0.28mm off (radius).
No wonder my bars were never round and I also had probs with small bar riding over the tool. (I know, a bad workman never blames his tools, I wasn't blaming them, I just never took account of this problem...)
Anyhow, all done. Just have to do it again on my other lathe when I have that up and running.
I fastened my grinder to a bar with some hose (jubilee) clips. This bar I mounted in my toolpost. I had problems with the grinder moving when I switched it on initially. However, when it was stable, I was then able to work with it. I think I will make a proper clamping arrangement for it.
