Brainstorming here, could use some ideas from the more creative elements here.
First, yes I know I should just buy a big CNC router, but that isn't going to be a justifiable expense for this. I have a stack of slabs that need flattened and used for countertops and tabletops for a project. I'm bookmatching them and ending up with up to 50" wide and about 80" long. I klodged together some scrap steel that was laying around and got a wide span conventional jig working, but...., this is just the most torturous thing I've ever undertaken for the sake of woodworking. The slabs are normal live edge ash stock, some places 1/2" has to come off, some places is only 1/32" or so. Problem is, by hour 4, I had made it halfway through the first side of the first one.
Having plenty of time to ponder my bad decisions, I got to thinking about mechanically automating the process. Maybe even Diy something CNC, but there has got to be a way that I can get that router auto fed across this slab so I can do something else while it works. There are very few new problems or solutions, so some other easily bored person probably already has a solution. Ideas???
First thought was to use a big reversing thread lead screw to move a router carriage, but I don't have one, especially that long. Auto progression could be done with a cam and pawl, something like on a saw filer. Probably a better idea out there though.
