Governor Assembled

Well, I stopped looking for the lost stirrup and made another one! I also went for pivot pins instead of the more often seen 10BA screws: I just have to make the fixture for drilling the 1/32" holes in the right place...
Progress!

Silver soldering paste for the stirrup join.

Governor Valve Links

Our caravan comes out of storage tomorrow so I had to finish the governor! The links are straightforward, but like many model engines, are well over scale and need to be reduced somewhat. For example, the butterfly valve link rods are specified 3/16", so in full size that would make them nearly 2" in diameter, so they are now only 1/8" diameter and to me they look much better!! The same applies to the adjuster, both in thickness and in length.
Some progress pics.

You can see that the solder paste leaves very little residues to clean up. Damned expensive but worth every cent!



A self centreing four jaw chuck is dead handy for these jobs.



My home made bending machine makes light and accurate work of the link rods.



Looking quite a picture now!

A Quick Escape from the chores!

While waiting for my caravan floor refurb to dry out I had a look at the crank case. It's a solder or rivet job, but if you have a 3D printer then this is what you do...

Printing the prototype cage in PETG. I have some black on order so I won't have to paint it.



Shaping the stainless steel insert.



Quite a nice fit!



That's what I call BLING!
