If I weld it on I will potentially ruin any heat treatment that has been done and may cock up the axial alignment of it. I know a guy who welded gears together in his gearbox and it screwed it royally.
My own personal philosophy is to never weld a machined part.
Hey gearcutter,
The gear doesn't necessarily have to be timed to a certain position on the shaft. The spline on the shaft has 22 positions and the gear has 30 teeth so there should be around 22 combinations between the two to find the correct position. Plus the gear and shaft that it is driving...
I imagine the power will be around 70+ HP at 10,000 RPM. This is the gear for the cam chain drive.
The bore of the gear is 28mm and width is 6mm. Not much at all unfortunately...
Cheers for all your replies and help guys, I really appreciate it.
Desertfox, a key way will be square and will protrude into each part by about 2mm, a hole drilled has a much nicer shape for stress concentrations and will only protrude 1 or so millimetres into each part. Good question though :)
Course I can :)

In this picture I have the key way in it.
I've been doing a bit of thinking and I could possibly drill the hole for the pin before I harden the parts so I don't have that discontinuity. I might make the two parts a wee...
Hi there,
I'm making a gear to go on the end of an engine that I am manufacturing. Before we start, no I cannot use a standard gear, or go and buy one. I need to shrink fit a gear onto a shaft. This gear drives a cam chain system for the engine. What is the best way to positively lock this gear...
