Making my own parts

[capner2112]

Here's a long awaited update to this project, namely the sprocket. I found some engineering data on how to properly design the toothform and since I'm not an engineer yet I really can't say if it'll work for this application (the information came the Standard Handbook of Chains textbook I viewed online). All of the information can be found in the below image.

xerxes- Ever since you put the thought in my head and considering I haven't moved past design, it's worth redesigning the drive-side crankarm to accommodate a spider versus a single pin. The benefit is it removes the need for the mating boss and bore get it concentric so long as my bolt pattern is concentric. I'll see how things work out.
