Pat,

Who has the crank? Maybe we should leave that a little longer, cause I'm not machining the center of the fly wheel down as far now on the revision. That, and the discs I got really vary in width, so it might be better to cut the final length of the crank per mating fly wheel, as they will very from one to the other a bit.

Thanks Ken for the nod to my Dad, Bob Jorgensen, who designed Engine No. 21 and built the first one. I know Bob would be very thrilled to see such work. Bob J. absolutely loved to build model steam engines and would appreciate this very much.
Bob was also in the hardwood lumber business and would love the variety of wood.

Per Ken:
"The main base is quartersawn white oak sitting on ebony feet and the engine bearer is curly black walnut."

Nice work Ken.

Team No.5, I think we are on a roll.

Pat J
That base is awesome!!! Way to go Ken!

No problem there.

I can also ream the holes in the flywheel for the crank all the same size if they are not already the same size.

Pat J

I will be reaming them all to 7/16" so that should be fine, just want to make sure the the crank will be long enough to make up for the extra width of the fly wheel.

What does everyone else think?

I started making a cylinder lagging tonight.
It is a thin brass tube, and I power wire-brushed it off, and put it in the lathe (about a 12" piece) and began to part it off.
I wrapped the piece in the chuck jaws with some heavy paper to prevent maring.

About 3/4 of the way through the parting, the part snagged, and tube collapsed in the jaws. I was afraid of that, and have had some trouble with thin tube before, especially brass, grabbing when parting off.

I will post disaster photos tomorrow. I think I can salvage all but about 2" of the piece.

I toyed with the idea of mounting the dremel in the tool post and using it for cutting off thin brass tube, but I thought I would stick with the traditional methods.

I made a bracket a while back for the dremel, but did not finish it, so I will either finish it or use the slitter saw in the mill with the rotary table.

I will get it right tomorrow.

Pat J
how about turning a piece of something to put inside the tubing to keep it collapsing

My video is floating in Cyber space I think. I will make a different one, when I get to the next flywheel.

My Wisconsin Badgers are playing in the Rose Bowl today!!! Shop is Closed, due to the intoxicants I'll be ingesting today.
