I have some ideas that I need to get into CAD and play with. The problem is the material. They would need to be made out of lexan or polymer, but I will have to engineer it a little better to verify strength. Does that machine have 3 axis tracking?
The other thing that I am thinking about but have yet to design would be a fold up shooting bench out of wood. Nothing too fancy, but the trick would be a three leg system so that it is stable on all terrain that you can level after you set it up. I get so sick of fighting around with my folding table and then it starts wobbling again after I start shooting. I have seen the RCBS ones, and while okay, they do not have the room needed to put my shooting log and any substantial amount of ammo on them.
I think of crap all the time. I just need to start putting pencil to paper and figuring out some more fine tuned designs.
