Hi Doug,
When I get the time I'll post a thread on making gear cutters and using them.

Thanks, I will look forward to it. Making my own gears and my own valves are the 2 things i would like to learn how to do next in my engine builds. At that point i would be willing to try a build from raw materials.

George,
 Nice little engine, and nice video as well. Thanks it was very informative. I am trying to block out the time to tackle a crankshaft project myself. Have the four jaw chuck so may as well give it a try.

Len.

wow. A crash course of machining tips from an obvious expert machinist. Can't tell you how much i am learning just from these short glimpses in to your builds. Would love to know more details on that gear cutter!

A lovely runner, you certainly have a talent for the small scale stuff George!

I had noticed the fuel tank bracket. Interesting to see how the bracket was fabricated. The crankcase build is very interesting too.

Thanks for the reply. They look sealed, but I wasn't sure.

The crankshaft rides on sealed ball bearings and the rod just takes a couple of drops of oil every now and then.

Smooth little runner. How is the bottom (crank) end lubricated? Thanks for the video.
