The Home Machinist!

I FOUND IT! Or at least a mention of it. Page 50 has just one line in the second paragraph says:" The connecting rod is 2-1/4 strokes in length..." This is part of an article dealing with anenclosed type of Steam engine using a desaxe style cylinder, so it may not apply in a standard verti...

I still cannot find the figures that I thought that I had read in Harris' book, BUT, I did measure my Stuart 10-V, an old reliable design. The Stroke is .750" and the Connecting Rod Center-to-center is 1.6875" giving a ratio of the conn. rod length of being 2.25 times the length of the str...

K. N.Harris reccomends that the length of the Connecting Rod should be 2.25 times the stroke of an engine. Al, I thumbed through Model Stationary and Marine Steam Engines by K.N.

Another helpful book, if you can find a copy, is "Model Mechanical Engineering" by Steele. It is a British publication and has lots of technical data.

Check out "Hudson Honey's" lathe. She shows that a LOT of work can be done on a small machine.

A Gatling Gun? Say----Pam why don't you start a new thread on that project with lots of photos. Maybe under the General classification.

Looking forward to the photos!
