I'm looking to make my own 4x5 ground glass for a Toyo 4x5 camera. I'm having a hard time finding the abrasive grit that everyone mentions, in any quantities less than about 1 kg. Would anyone on the forum have any excess grit that they'd be willing to sell to me, or does anyone know of a place to purchase a smaller amount in Australia?
I've also tried looking for valve grinding compound without much success.
Thanks, Justin
