Looks like wood swarf.
Company that closed down. It was the last one I think.Excelent price, where from, do they have any more?
Oh Well, Thanks for the reply.Company that closed down. It was the last one I think.
I'd made a bottle brush bristle pull though and cleaned out the hollow spindle , not a lot of gunge in there . The chuck was different .Swarf just gets in there, mine's full of crap. I pull a rag through it when I can be bothered but usually just ignore it, it doesn't do any harm. Sometimes if I'm doing big through-bores I can hear swarf sprinkling out the back of the headstock.
Slip thin oiled card between the steels to stop them rattling around and prevent them " Ringing " ( sticking together ) ? We were not allowed to handle our parallels with bare hands because the acid on our hand would burn the precision grinding and make them useless .
Today I have once again aquired what I have earned ... now that the little Myford is able to do more - or rather, I have learned to use it a bit better - more stuff was needed again.
And I got what I paid for ... the box already gives away the origin

A set of parallel underlays, or what do you call them?!?!
Parallel supports 100 mm, Width 10, 14, 18, 22, 26, 30, 34, 42mm
Thickness: 4mm; Parallelism: in pairs Tolerance IT 5 according to DIN 7168; Accuracy: DIN 2768; Accuracy class: f (fine); Hardness: 58+/- 2 HRC
Whatever may be true of it.
So far I have only unpacked two pairs, nothing daunting at first sight, but no sublime quality either ....

I haven't looked at squareness and parallelism yet (but that shouldn't be soooo difficult, should it?), but the edge treatment - or lack of it after grinding - is not at all convincing.

And of course the storage notches in the wooden box, which were already not very suitable for shipping, after the removal of the wrapping paper, are no longer suitable for the parallels ... everything is flapping around.

So I got what I paid for (probably a little less) but what I needed in used, old and good was not to be had.
Good night

I was at a big cam grinding facility in Italy, they were doing me a favour by grinding chrome plated steel disc around 400 mm in diameter flat (by gluing it down, not pulling it down flat on magnets as it had been made) - and to check it was really flat, my mate took one of their parallels, licked it, and put it on the surface . . . it stuck . . he pronounced it flat . . . cue a mix of Italian puzzlement, horror and shock from surrounding people, from the main man down!Slip thin oiled card between the steels to stop them rattling around and prevent them " Ringing " ( sticking together ) ?

Proper engineers apparently .Who comes up with that crap?
