Sorry for the late reply I was camping this last week.
I didn't make the gears from scratch. I found gears that were the correct size.
It took me 2-1/2 weeks of searching the web and asking questions before finding the right answer.
As it turns out the vertical Briggs v-twin's were the right size. Around the 18 hp range.
Had to cut the larger camshaft gear off and the smaller crank gear is a press fit
I did send the smaller gear off to be reamed for a precision fit to the new crankshaft.
I can only imagine how much side load there would be on higher HP engines. Then put straight cut gears in an problem solved, free flowing gears. Its gotta be a huge improvement.
Here is a picture for reference.
