I replaced the bed on my Myford S7 a while back and the old bed has been sat under my bench ever since. Before I have my next tidy up and take it to the tip is there anything it might be useful for.

Raw material for your next project?

Did you replace it because the old bed is beyond being reground? If there is enough meat for a regrind then it may have some value to someone. Maybe a super long bed could be rigged for making cues or the like.

If the S7 has the bed type with a flat bed not inverted v then each shear can make a nice camelback transfer reference flat.

The point here is that the bed is stuffed so how could it be a ref. flat?

and yes myford beds are flat.

My first scraping project was a S7 bed. The simple shape makes for a great first project.

The problem with a re grind is the cost , I managed to pick up an excellent second hand bed much cheaper than a re grind

That's an idea , I might have a go at scraping it.

David/ Peter,

Do you have an idea (perhaps from measurements with straight edges and feelers etc) how much wear is on the bed you have? Peter, how much wear was on your S7 bed scraping exercise before you started?

Scrapers are easy to make. Buy a sandvik tip and make the rest. Get a 1500-2000 grit flat lap disc off ebay (or get a set of three different grits for about 12 quid) and fix it to your chuck face with double sided tape. Turn lathe at 300-400 rpm and use it to sharpen to 5 degrees negative.

Phil, see the image below. wear is marked in ten-thousandths of an inch.

The point being it is a nice bit of cast iron which when cut down to say 2ft long could be reground and scraped with a lot less trouble than a proper bed regrind.

I was hoping to make a scraper and tried the link above but no joy, the link has no mention of making scrapers. Was the wrong link posted?

I'm sorry yes it is the wrong link. I will remedy that right away, though I can't edit the previous post so I'll put it here.

EDIT: here is the link I meant to post.

Buy the steel to make the shank from here
