Hi Kryn, Guys,
No ! I was actually rooting around in the scrap metal bin at an engineering works when I came across the yellow tube, that was when I discovered what it contained. I took it to the foreman, who said if its any use to you, keep it... So I did. :2tsup:
I also got a couple of bits of square HSS, a little rust on them, but for free, I won't complain.
Col: I haven't seen a ten bob note for a long time. :D:D:D
You're lucky, a lot of places won't let you root around in their bins. Where I get my steel from, they have a bin out the back, and don't like me going in there either, something to do with liability.
If I'm stupid enough to injure myself in their bin, I'd be pretty stuid to try to get some pay out??? All I ever see in there, is lumps of bent material or really short bits that aren't of much use.
Hi fellas, thats a good find BaronJ. I have the same scraper. You may find the tip insert is not hss, mine are solid carbide, they're about $40 apiece.
cheers Alby

What I find surprising is that someone has thrown them away. Though I do sometimes come across brand new bits and pieces that have been sent to the scrapyard.
The bits of HSS that I mentioned are a couple of lathe tools, about 3/4" square shank. They just fit into the toolpost on my Myford lathe. Of course they will need to be reground to be of any use.
Hi Baron, I found similar pieces on Ebay, https://www.ebay.com/i/272791200415?rt=nc. $228.00 Australian, with free shipping for 5 pieces.
Milling Tools Your handle is 66 pounds inc VAT
Indexable Inserts The blades look like they're 38.28 pounds each.
So it looks like a really good find around 260 pounds worth. If you find anymore, I'll have one thanks. :D

Very lucky if you want to do scraping, its crazy how hard they are to find. Carbide is a lot better with cast iron I heard, HSS can work but it dulls quickly.
I wonder what these are....

Like it says; for scraping cast iron, white metal or bronze plain bearings. Many early motor vehicles and old engines before the days of precision bearing shell inserts used white metal (Babbit) bearings where the metal was poured directly into the big ends and into the engine block for the mains. These were bored slightly under size, then scraped to a good fit using bearing blue as an indicator and the bearing scraper to remove the high spots.Quote:

Are they just a hardened steel scraper or do they have some carbide inserts?
Do you mean the bearing scrapers? If so, mine are both high carbon tool steel. I presume HSS ones would have been available - don't remember hearing of carbide ones. You can see that the business end is curved upwards to make access to the bearing easy. There is a recess between the two cutting edges, which does not extend right to the tip. They are sharpened by holding the scraper flat on the sharpening stone so both cutting edges are sharpened at the same time. Mine need frequent touching up when used on anything harder than Babbitt.Quote:
