That will work. The one thing I would add to it is some bracing at either end to keep the rails perfectly upright. You can add on to the jig and it will rout straight lines for you. If you want to go parallel with the rails then clamp onto your cross arms on either side of the rails and if you want to go cross ways then clamp blocks on the rails so that the cross arms can only go back and forth.
Jig for burnt wood inlay
This is a jig I made (but haven't had time to try out yet). My goal is to put fully charred wood under it rout it for inlay. I can't rout for inlay first and then char because the extent that I char would burn up the rout for inlay. I'm thinking I'll use a candle to make the thing slide around smoothly. Any other ideas about using this before I fire it up? I'm a stay-at-home dad with 2 little kids, so I doubt I'll be able to use it as soon as I'd like. Thanks for any ideas.
