1¼~1½'' now that's cutting length not OAL...I recently bought the small Bosch bench top router table and a Bosch 1617 combo router/plunge base. For my craft work I want to joint wood probably no thicker than 1". What would be the most suitable cutting length for a straight bit to do this?
David you're falling into the trap of using a router as a do all tool. You're going to spend time and money on a makeshift set up that will be too short and Mickey Mouse to do any good unless you plan on only doing very short boards. But if you like being frustrated then the router is the way to go.You're going to spend $25 dollars on a bit and an hour or so working on your fence and in the end what have you got? Spend your money of a used 4" solid cast iron jointer that can be had for under $50 dollars any day of the week. You don't need anything big if you are only doing edges. If you don't want to buy a jointer then do it on a table saw. I do a lot of work using rough wood from the saw mill where the edges aren't even close to being straight. I sold my jointer years ago and have never missed it. I use the table saw when needed but if the boards are under 4" wide I usually just put them through the thickness planer on their edge.
