As Blue Eaglebum mentioned, LVL would be a better way to go when building a bow form. One thing I would add though, is the use of a router with a 2" straight bit that has a cam roller on the bottom of it. They are available from the woodcraft stores. What you do is to cut out the bow pattern that you want to use on a band saw, using 1/2" plywood. After you have both ends even, and smooth, mount this to your LVL, inboard about 1/2" or so from your drawn lines that was cut out on the LVL. Use 1" wood screws to hold it in place. If done carefully, you will have a surface that is cut 90 degrees from the side of the LVL. ( Use caution when using a router, or any other power tool.) Be sure the LVL is mounted securely. Also I purchased my 1/2" drive router from "Harbor Freight" Stores at a decent price. Good luck. John
