  • Bought a small ruby stone from China

    They weren't mucking around with the packaging! Stone is 10 X 10 X 100 mm. Wasn't broken

    I recently received a 4"x6"x10" box containing a single 12" hacksaw blade.

      From Amazon? Amazon send me big boxes with almost no padding. I've had more damaged stuff from them than anyone else.

            Odd I bought some gershwein slips from the US recently, the thin ones are fragile or brittle I should say, at the same time there was a faithful tools "offer" at the builders yard, an 8"x3" double sided diamond sharpening plate, and a rubber stand for the same for £19, I thought that's ok, so gave it a go, never used as big a diamond stone before, one side is 400 and the other 1000 grit, OK here goes I thought, let's try a chisel, picked up a modern Bhaco chisel with no edge, to be honest bhaco chisels are soft as ****e, but against all odds I put a really good edge on it, well pleased, even better on good hard steel like a sorby.
            I think I'm going to invest some more in diamond, though bigger stones are going to PE spendy I think.

              Ups has a deal with the post office so now UPS brings light Amazon packages & the poor lady from the post office prings the 80# boxes of lead, steel, etc in her car. I really feel bad but it wasn't my stupid idea.

                yes, what are you making? I've been looking a making jewel bearings, but there are issues with grain and direction apparently so it doesn't crack.....curious what you're doing with it.
                in Toronto Ontario - where are you?

                  Um, I think he said ruby stone, A 'ruby stone' is not a 'ruby'.

                    Sorry to disappoint, but kendall is right. It's just a fine stone to be used as-is. StefanG used one in a recent video. Skip to 23:08

                      Was it folded in half?

                        Didn't know about using a ruby stone for polishing. I found some on MSC, and they are actually made from aluminum oxide:

                        Another source seems to have the real McCoy, made from sintered ruby, for about twice the cost:

                          It's the gesswein stones I bought from the US recently, I had my old ones since the early 80s, if you take care of them they last well, I keep mine in a leather chisel roll, flats squares triangle and round, and of late diamond ( I use wet as I found dry kills them, I use lapping fluid, think it's mineral oil myself) they are without doubt the best stones I've ever used, there are cheaper but no way as good.

                            -Technically, proper rubies are also made from aluminum oxide.

                              Diagonal in the box.
                              A squared plus B squared = C squared
                              4*4+6*6+10*10=inside of box
                              16+36+100=152 length inside box
                              12*12=144 length of saw blade
                              easy fit but uses up less than 1% of the volume
