• This was my birthday present this year.  It proves the theory that anything can be fixed with a pound of JB Weld and a putty knife.

• Being a birthday gift, I feel an obligation to make it run.  This was some great grandfather’s garage project supposedly from the 1940’s and later (fixed) by grandkids.  Although it would be easier to make an engine from scratch, I started with the head and slide valve.  It has a 1-1/2” cylinder with a 1-1/2” stroke.

• That poor thing sure is in dire need of some TLC...
  
  Looking forward to see how it turns out, once you get it all cleaned up

• A challenge in any case. I'm looking forward to seeing the result.

• I built a frame to replace the broken board.  The cylinder slide and timing mechanism will be interesting to redo.  I’m starting from the cylinder and working backwards to the flywheel so I can reuse as much as I can.

• I am laying out how the engine will look.  The original flywheel was clearly something the original builder had under the workbench.  For artistic reasons I decided to use this flywheel from under my own workbench.  The steam chest will have some artistic additions as marked.

• Made a new longer connecting rod with a removable end cap.  I’m mocking up the original valve train to see how it works.  It is actually timed as it sits.  I will try to keep the original design where practical.  Fun project.

• This is just a low pressure test to make sure I got the valve train figured out.  I’m pretty sure it was not assembled correctly when I got it.  A little precision cardboard and supper glue worked nicely to extend the valve connecting rod. The original aluminum parts are really loose and rattling and will be replaced before I tear it down for final assembly and cosmetic work.

• Replaced the valve rod.  The slide valve link and valve are next.

• I made a new slide valve to replace the original.  I’m chasing down the clunk.  The main bearings are poured and worn and the crank disk has some run out.
