Myford Super 7 Bed Wear

I think I'd've wanted to clean it with a soft brush and a gallon or three of paraffin or white spirit, somewhere I could drain the runoff. And have a look at the headstock bearings.

Not that I've ever seen grinding sparking do anything like that - I'd think you'd see it on surface grinder tables all the time if it was a normal result - but it isn't a comforting explanation.

I'd rather believe summat else, me...

Hello Mike,

I'm sorry to say but just cleaning may not be anything like enough to remove what might be lurking under the saddle. I would be stripping the saddle completely to be sure and checking all the other sliding surfaces and dovetails

Another felt wiper across the front of the tailstock is a good investment, you will have to make the holder and find some thick felt but it will all pay real dividends in keeping fine swarf etc away from getting into the sliding surface under the tailstock shoe.

Regards

Brian

Is there similar damage to the rear edge of the bed or just the front?

Does not look like the results of toolpost grinder to me. Never seen that kind of spark erosion around grinders before.

Looks more like some kind of steel tool was rested there, many many times over. Wood turning? Knurled handle of a tap wrench - used over and over several thousand times in a production situation?

If only these old machines could talk! (Although their language might not be publishable in cases like this one.)

Chris: No, the damage is only to the front edge of the bed.
