can you tell me more about the rig you built to hold the block? I'm currently struggling to dial this all in, and this is really impressive. i'm curious what type of wood you used. also, it looks like the resingrave is just barely higher than the outside frame, but i'm curious what the difference is. also, I've read elsewhere not to use felts for resingrave, but since your prints seem to be coming out spectacularly, im willing to rethink that. alllllso, there appears to be one sheet of something blue under the felt that i can't quite identify. also, do you want to just sell me one of these? great work/many thanks
