Re: timing gears
re your question on skew gears, you could make them yourself, the next
issue of Model Engine Builder magazine will have an article on making
skew gears in the lathe. There will be pictures of the machining
process and detail drawings of the fixtures to machine them as a
supplement. The dimensions of the two fixtures are very close to
your requirements, the ones in the magazine are dimensioned for .5625"
centre distance. The whole article will be based on making the
camshaft drive gears for Edgar Westbury's road roller engine, 2:1
ratio 9/16" centres.
