Very nice work done on the good looking con rod, and the lagged cylinder looks very smart too.  This build with attention to extra detail is really getting the best from the smaller sized Stuart beam engine.  Dave

Well done!  The dark lagging and the bright brass look good together!  :popcorn: :popcorn:

Thank you all for the kind comments. 

Spent the day making the piston, piston rod, spacers and shafts for the parallel motion.  It works as it should.  Stuart did not allow for clearance in their dimensions, so if you make everything at the mean, you will have some interference.  Removing a little material from the excess lengths of thread takes care of any issues.  The slide valve and linkage are next. I still need a base, some paint and I want to reduce the size of the heads on the 2BA screws and of course make some gaskets.

It's all looking very nice. I think the lagging looks spot on.

The slide valve and valve related parts are machined and in place.  The last part, (three parts), will be the rod that actuates the valve mechanism.  The engine should be ready for a test run on Tuesday, then it will be dismantled and finishing touches made.

You are cracking right along with this!  It is looking very good. You have reminded me I need to give the beam engine diorama a dusting. Of course, I get to play a bit as well. :cartwheel: :pinkelephant: :cartwheel:

It lives!  I mounted the engine to a nice piece of Cherry and tested it.  The steam chest gaskets are in place, but it was run with no rings, no cylinder gaskets and no gland packing.  Despite that, it ran fairly well on 15 psi, and less and it sounds much better in person  I did not run anything in.

It’s time to tear it down and make some finishing touches and add some paint, gaskets and gland packing.

Runs great even without the  gaskets and such,  going to be even better with them! Great work!

I appreciate all the comments and encouragement.  A governor may be added later, but it won’t be a Stuart governor, (it will be smaller and probably use bevel gears). 

The weather forecast sounds like Sunday will be a good day for painting.  That gives me some time to get things ready.  It was nice to see it running.
