[SEL] Gear Cutting Needed

[Jim Kirkes]

Hi J.B.,

I also should have added to read the section on gears and 
gearing in Machinery's Handbook and also to make some good 
measurements of what is
existing.

I haven't cut any yet, plan to do some. I always pictured it 
as cutting the blanks at a 45 and putting it in a divider 
and cutting the teeth. A friend cut some for his engine and 
they didn't look quite right, the teeth didn't mesh fully on 
the outside. I looked at a blueprint I have for an old timer 
gear, the blank is cut at 48deg7min. The cut is made at 
41deg24min. Tghis would let the outside of the tooth mesh 
deeper.
