Hi ega, if it's the one I'm thinking of, it was in October/ November 1997 in MEW.

Regards Nick.

Nicholas Farr:

Yes, indeed, and thanks for the correction!

I suspect that Gray has provided the answer to the OP's question.

Your error over 25 mm or 1" will be so small as not worth worrying about.

Your mag chuck may well be distorting the work if it is thin. This is what I was hinting at in my earlier post. Old feeler gauges make good packing when placing work onto the Mag chuck, before engaging the magnets.

The Mag chuck should from time to time be reground, but be sure all other sources of error are eliminated first.

Wear very often takes place in the centre of the table. It is where most people tend to place the work. Operators of Surface grinders will often place parts all over the table to minimize wear and save on table regrinds.

Strips of thick rubber with an aluminium backed edge. Rather like a Tenon saw, make good cleaning aids for the table. To remove dust and coolant, but nothing beats the palm of your hand afterwards.

Regards,

T'other Gray,

My use of a swing grinder showed you cannot use the full width of the thicknes of the grinding wheel. When truing it I was instructed to take off more than half the contact surface leaving a narrow contact to cut and grind.. It was just a matter of truing and then taking off a bit more to leave the original truing to cut. I only ever took very small cuts to clean up jobs.

As only a relatively narrow band at the outside of the wheel can be used for accurate grinding why are swing grinders always fitted with such bulky wide faced wheels?

Seems silly to pay for so much grinding media that will simply be lost as dust to create clearance when truing. Especially as quite deep, narrow cup wheels are made. Is it as simple as safety? I imagine a narrower face cup wheel will be more vulnerable to major accidental damage should an over-large feed be attempted.

For many years I used a deep cup 6" white wheel with, I think, 1/2" face for my finish tool grinding and drill sharpening with a Picador swing across the wheel device. Partly because the narrow face seemed more suitable for use with the Picador but mostly because it was offered at the right price at the right time. Working only from the side made the the rest simpler too.
