Re: White Paper Discuss: Team 716, 2004 Dual Speed Gearbox
It took me awhile to catch up on my real job, here is The Who'sCTEKS 2004 gearbox.
I am hoping that this will start the landslide of designs I was promised, 195, 571, 900, etc. Plus all the usual suspects!

Very nice, compact design. Time to start up my research... 
Do you have certain suppliers where I can look up the different parts, I wanna make a price quote for these.

My suppliers:
I use Motion Industries (MI) for the gears, bearings, hardware. Note: I bought stock gears and modified on a manual lathe.
I used PIC for the Module 0.7 gear - six weeks, promised in three, glad I ordered it in August! MI said they could get it for me but would be from PIC. Team 571 used plastic gears for this with success so this is an alternative route. There are not many suppliers for 0.7M gears.
Aluminum I got from Yarde Metalsand my local True Value Hardware store (one of our sponsors), any metal supply house would be good.
Some of the commercial part numbers are out of Small Parts Inc. They were a big part of FIRST including giving each team a credit for purchases and I still use them because of that. For you veterans, remember the rule that you could use anything as long as it came from SPI?

Just use a piece of aluminum angle, and the mill out the profile on the drawings.

The angle pieces were made from 2x2x1/4 aluminum angle.
For a good reference to shapes and metals go to http://www.mcmaster.com/ and type in 'aluminum' for the search. Select aluminum and you will find a reference page for shapes and the different alloys available.

Yes, 2.28 is the length you would machine the angle to.
