Title: Steam engine shaped object
Post by: DJoksch on June 13, 2021, 11:17:32 am
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 grandfatherís garage project supposedly from the 1940ís 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 1-1/2Ē cylinder with a 1-1/2Ē 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.  Iím 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.  Iím 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.  Iím 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.  Iím chasing down the clunk.  The main bearings are poured and worn and the crank disk has some run out.

I am convinced that you will get the problems under control.

Iím using an old clock stacking tool to make holes in the bands (not the good one).  The little screws should arrive today so I can finish the engine.  The next issue is deciding on a common interface to the boiler.

Finished detailing the cylinder.  Should have it back together today.

Back together and running.  I have a displacement lubricator to install on the Clarkson vertical and am off to make steam lines to connect to the boiler project.

I'm excited and looking forward to seeing it all together in operation.😀

Just finished the supply line to the boiler and will test the engine under steam in the morning.

A fantastic outcome!

Thank you for a great build thread.

The boiler looks great.
