Thanks for the replies... here are some answers:

Jim - you would be suprised, I can be a space case sometimes.

Cory - thanks for the nitpicking, it is needed. I will make the change and wait for other stuff that may need updates.... they I will re-post it after a while. Since it is in "public domain" it needs to be right. If you or anyone else finds errors, please let me know.

Tytus - a CNC end mill. Our high school machine shop made the parts that needed CNC'ed on a Haas machine, I believe.

John - thanks for the support. The good thing about the machine dogs is that they are permanent... you don't have to worry about them once they are made. Sure, they take a little more time to machine as opposed to putting in dowels, but it is worth it. As for 2004... it will have more recution and reduce parts. We would've liked to have about 25% less rpm on the output shaft.

Mike - it would be great to see people build these in their free time. Better yet, improve upon the design and post your findings. (one of my favorite quotes: "If I have seen further, it is by standing on the shoulders of giants." - Issac Newton). Take what we have done here and improve it... that is what Newton meant.

Sanddrag - the gears actually don't cost that much. Keep looking around for suppliers. These gears can be purchased, off the shelf, for about $90. Two sources that I used are Martin Gear (20 pitch, purchased through Applied Industrial) and Rino Mechanical (32 pitch, purchased direct).

Joe - good for you. Designing a gearbox in two days is not easy. However, quickness in design can cause errors, just as you made errors while criticising our design. We did not use a 24 or 32 tooth gear. Also, I am not sure why you say "what took so long?" Do you have your design posted on the web? If so, please reply with a link. Also, I trust that you are a good designer, but it would be helpful if you wrote with more clarity. It's somewhat hard to understand what you are trying to say.

Again, thanks for the comments... keep them coming.
