Re: Drive Assembly Sprockets are Custom Bored

All heat aside, I love the transmission. I also like the information in this post, I most likely would have missed the shaft being metric with out it. Being responsible last year for getting 3/64" key ways cut by mistake in a pair of 30t #25 sprockets, (was supposed to be 5/8" bore with 3/16" key) we used the T shaped key way and adjusted. I took one look at the casting and said wow, custom die cast and low cost to make so many, somebody did a great job with the over all design. After my first read of this post, I looked at the output shaft and thought, Cool start with 3/4" hex stock and go from there if you want to get to 5/8 final out. My second read finds use a metric drill and metric broach, if you need a different final sprocket. Thanks Paul for the great work and the learning that has flowed from it. Tom Cooper
