I know that a lathe is really not a cylindrical grinder but for an odd job it may well serve as one, as long as it is well protected and cleaned afterwards.

So which commercial toolpost grinder I could fit on my ML7?

There are 2 inches between table and lathe axis.

@john halfpenny, @bernard towers,

Dremel is not good enough (stone is bouncing). For internal grinding I have adapted die grinder (Milwaukee) which has a ground front section allowing to mount it in clamp. It does great job (and together with taper turning attachement it was successfuly used to make MT2 taper in spindle of my ML7 running dead true – weird as it may sound but *original* hardened spindle from Myford (Nottingham) had misalligned bore, so end of test bar was making small circles, 3 different bars tried to the same result).

This cannot be adapted for between centers work for obvious reason.

I do not have auxilary milling spindle and I would rally love to be able to fit 3-4 inch diameter grinding stone for grinding now and again an odd spindle.

Yes I have learned how to lap and hone these kind of jobs, I can even do really good job with finer and finer sandpapers o get down to 2 tenths of accuracy while pressing sandpaper with finger or a plasic strip – but I have really decided o stop wasting time and stand 2 or 3 afternoons a my lathe and piddle around o get an odd piece done.

Another hint:

Sunnen stone mounted in toolpost can do a great job as long as your turned piece is paralell, but there is much piddling close to shoulder.

Nevertheless I just decided to save my time and get a tool meant for the job.
