Stirling "Miser" Engine

Might as well get this posted as an incentive to carry on till finished. Need to order some ball type end mills to finish the column per (Jerry Howell's) drawings.

Jim,

That is a great start. You gonna work on other parts while you wait for the ball type end mills?

Keep the pictures coming.

Being that I'm chained to the machines do I have a choice?

A few more photos:

This is the "Main Frame" picture. The two bigger holes need to be enlarged but enough work for 1 night.

They are drilled @ 1/4 inch and I used a tool that was suggested by Marv in another thread to align/center the part to the rotary table.

This was the setup:

Took and awful long time to make that one piece.

JMI,

I built 2 of the Mizers last spring. It was a fun project. I used a corner rounding endmill to round off the edge of the base plate as long as it was already clamped down to the rotary table. I put a cast iron sleeve in the power cylinder so the outside could be aluminum. Did you purchase the hard-to-find parts from Jerry Howell? I used a reamer blank for the main crank shaft because they are very straight & your flywheel will run very true. Have fun with this!

Mike,
Have the corner rounding mill on order as well as a few ball end mills for the various flutes. I suppose it would have been easier to use the rounding mill as you did when the part was already in the setup.
Already have the HTF part kit.
Have used drill rod for the crankshafts on all my previous (read 2 :big engines with success and will likely use it again.
Did you paint yours? I'm thinking along the lines of anodizing it.

Thanks for you comments.

I plan to black anodize some of the parts.
