R/C Steam Turbine Tank

Step 8 Sprocket Shaft Bracket

Overview:
This step describes how to make the U shaped bracket to support the 2 Sprockets needed to gear down the turbine engine to the clutch

Details:
Making the bracket to support the sprocket shafts was fairly easy. You just need some sort of a bracket where the sprocket shaft can spin easily without much friction.

I used aluminum because it's light, and easy to bend. You can find all sorts of sizes and shapes at your local hardware store. Using a Dremel tool with grinder wheel, you can cut the soft aluminum easily. After cutting the desired length, you can clamp it to a table vice and bend it by hand. Drilling is also easily done with a power drill. I found these flanged shaft collars laying around, sorry but I have no idea where or which R/C vehicle it came from. You just need something that is slightly larger than the shaft, that provides smooth rotation. Drill a hole about the size of the collar, and push, or gently hammer the collar in. Test the alignment by sliding a 4mm shaft in, to insure that it is lined up and turns smoothly.

Drill the bracket's base and corresponding holes on the chassis. Mount the bracket onto the chassis with a couple of nuts and bolts.
