I hope this helps someone out there, and let me know if you need any advice if you decide to make your own.
Thanks for watching!
I have entered this project in the ShopBot Challenge so if I were to win the grand prize I would use it to start a furniture and or boat building company. With such a sophisticated tool at my disposal I would be able to quickly prototype my designs, refine them and finally mass produce a finished product. The list gos on in my mind of all the uses this tool would have for me, but mostly it would mean the start of a new career.
Best of luck to all,
