Please keep us in the loop on your progress and any additional recommendations and cautions you and Bert come up with. I really like your fixture idea, and may borrow it.I plan to make a steel fixture for grinding my 4 X 1 stones, consisting of a channel that is wide enough for the stones plus 2 layers of notepad cardboard. There will be set screws along one side to put even force on the stone and a plate at the end for support. I'll pregrind the bottom so the stone will be held flat (or on 3 points as necessary). When I'm done the jig I'll post a photo or 2.
I believe Bert's diamond stones are vitrified bond, I'll check with him on this.
My diamond stones are coming as resin bond (cheap, less than 20$ CDN each). I know that you can't put much pressure or generate much heat or the resin is toast. I'll be plunge cutting as well, but in tenths with very slow hand wheel feeding, and waits at the end of each pass. I won't be using coolant, even though I have the setup. I don't intend to clean up 100% of the faces, so if there's a little around the edge not flat, NBD. I want to get to the end result for this test with as little fuss as possible.... About the jig - for a very experienced grinder hand, I'm sure the finger boards are very safe. I'm absolute novice to SG, and rely on Bert for my info. For this test I'm much more comfortable making the jig. Maybe one day I'll make finger boards and try it. -- When I've got a lot more miles on the grinder.
I worry if the parts are just blocked in, then there is too little pressure on the stone to keep it from vibrating and moving. just my $.02.
I re-read the latest comments on Robin's video last night and he used the same Shars 505-2233 resin bond wheel that I purchased. It is nice to know that it worked for him...
