SO--I've been working alongside the machinist on the engine for my '61 Biscayne and today while running the "stone" (that's all it's referred to in the shop) over my cylinder head surface to clean things up--I F'd up and let the stone fall onto the floor, causing it to break. The problem is-the "stone" is about 20 years old and my buddy almost lost his breath when I turned and said "F***". Now--any of you who know what I'm talking about--as I barely do--you might be able to direct me to an outlet or manufacturer of these "stones". I've looked all over the place and due to not knowing the grit or abrasive number of the "stone"--I'm a bit lost. I've checked the Norton website and other similar companies and there's a lot of different sharpening stones--but I'm not sure if they are the same. Many of them get to be pretty $$$ as well. I'll describe the "stone" as this--it is about 4" x 8" in size, about 1/4"-3/16" thick (probably was originally thicker and dimensions may have been larger as well) and has about the same abrasive feel as some 600grit wet sandpaper. This stone has a "slate" colored appearance and may almost have a green tint as well. It's used while wet with solvent and does not erode very easily. It works very nicely when knocking down the machined surface ugliness, AKA light rust and surface imperfections. This is about the best description as I can come up with for you. Again--it is routinely used to clean up the oil pan rails, cylinder head faces, rod/main cap mating surfaces and engine block cylinder decks if they are not milled/decked via machine methods. Also-other metal-metal mating surfaces have been "stoned" with this piece that I feel I must try and replace. Any help would be greatly appreciated.
That's a pretty small pocket sized item--I don't think that's anywhere close to what I'm describing sir.. And that's a diamond stone--basically for knife sharpening--unless that's what others are using--its definitely not the same.. 4598A92 Is a 10" x 4" Diamond stone--basically a nickel bar with diamond embedded.. ???
Can you ask your buddy? He may know where he got it. Can you get a picture of it? I hope your buddy appreciates that you are trying to make it right. I lost a friend because he honestly didn't care that he lost a set of ramps for my car trailer when he borrowed it. I could have gotten over it pretty easily if he had actually cared. He didn't, and I don't need friends like that. Is this it? http://www.goodson.com/BB-9-Burr_Buster/ Jason
The problem is much of the raw material used to make these stones 'back in the day' is gone; all mined out. If you're trying to find an exact or semi-exact replacement, you'll probably have to hit eBay for a used one. Otherwise, you're pretty much stuck with the 'made-made' stones available these days. If you go used, look for 'Arkansas' or 'India' stones. The greenish grey color was probably a Arkansas stone.
Maybe one of these! greenish gray is usually aluminum oxide and normally quite course, the orange ones are quite fine in the 600 grit ballpark. norton is a good brand http://www.sharpeningsupplies.com/N...serID=70584779&SessionID=HDyOh3HAYB3c4ERBXaKv In the shops I've worked in a 1/2x1/2x6 or a3/4x3/4x8 orange india stone is the normal stone for rubbing on machine tables to remove burrs and I suspect would work well for your buddy. An arkansas stone is too hard for most machine shop use, it works better for very hard steel such as knives and gun sears etc.
I'll try and snag a picture of it later.. And--that link you posted was a source I already checked--and those stones look like about as good as I'm going to get. Strangely I didn't come across that "Burr Buster" that you located--I'll be placing an order immediately as the description fits perfectly! My buddy actually mentioned Goodson as a possible location where the stones were gotten from. But-he couldn't recall and the names of all the sharpening/honing stones became too numerous to jostle any recollection in his head.. And yes--I motherf'd my own goof up and he gave me shit all day--but then I think it was because he was befuddled by my immediate offer to find a replacement--not something too many people care to do nowadays.. I had to remind him that I hadn't broken a single tool in the past three weeks--I offered to find a way to break some more though.. ;-) Steve--I'm sure what you say is mostly correct-and finding a replacement is a requirement for me to make my mistake right.. I'd also like to see/feel a couple stones before buying them for comparisons sake--gonna be a little difficult though I think.. I'm already turned onto those Arkansas and India stones as the descriptions are pretty good in comparison to what the broken piece was used for.. Steve and Rich--Both of you referenced the same Norton items which were about as close as I thought I was going to find. But--I think for now I've got an option with the Burr Buster mentioned before.. Thanks all of you guys for your helpful and rapid responses..
Sounds like you are looking for a set of stones for a Blanchard grinder. Go to a machine shop supply site. You might have to ask your buddy how high of quality the broke stone was.
goodson used to sell stones of that size for doing work out in the field but its been eons since I bought one since they last so long and basically Goodson used Nortons stuff , I would call Norton direct and speak to a tech for help as they have more stuff than you would think about and you might have to send part of the broken one if you want it matched . most shops I know today use the buff pad stuff and use a table style grinder to face the heads as you can make the head surface uneven
Check out "Kinik abrasives" They have flat sharpening stones 1" x 2" x 8".. Sounds like that is what you are talking about..
This is what I use at work. Not exactly sure where they get them but most of the stuff comes from Grainger. It's a Blanchard Burr Buster. Sent via Illinois Bell Telephone Company's Car Radiotelephone
Blanchard Burr Busters are kind of a fine grit stone. I work at a Blanchard grinding shop and we dont use them much any more. There are cheaper and better (IMO) stones out there. We use a two sided rectangular stone about 2 x 6 inches that has a rough grit surface on one side and a finer grit, similar to the Burr Buster, on the other. But its a LOT cheaper. I can probably get you the info on where to buy them. If youre interested PM me
http://www.kbctools.com/can/Navigation/NavPDF.cfm?PDFPage=611 KBC Tools is a good source for most machine shop- type tools. They carry brand names as well as their own cheaper house brand stuff, most of which is pretty good in my experience.

Got my burr buster today--it's not quite as fine--but it's got a nice elliptic curve to it that will fit the hand nicely..
