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!
John

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.


Using a 'Frog' to hold the boss onto the arm



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!

We Are Connected!

I managed a couple of hours in the workshop today as we've postponed our caravan holiday for a few days until the storm passes through.

Thanks to a knowledgeable friend I now have what I think is a neat solution using XT30 connectors. I'm using a multi-voltage adaptor which also drives my barbeque spit, so I've left the various plugs on it for the time being. BTW the 4mm set screw holding the wheel on is temporary!

I did a few hours on the beast as the caravan is now ready for the Lake District trip. There's still some studs and the pump links to make and, of course, the parallel motion, but it's nearly there and looking quite nice!   :)

Superb John.........[just one point if I may........the 'asbestos' type lagging on the steam pipes would in most cases be shown in white].....

Gloss white is great....any oil drips wipe off  :facepalm: without staining a flat white surface].....sets the plant off very well  :ThumbsUp:

Hi Derek, and thanks for your input. I was intending to paint the lagging white, but as I've used waxed lacing cord I have to be a bit circumspect over the method in order to get the paint to stick! I will make a test piece and report back...

Not necessarily. The asbestos was quite often painted a dark colour, maybe because it was going to get dirty anyway, and also to stop it fraying.
