The bosses look good, but whatever you think would be best for your build!  You are the master engineer on this project, so what you say goes! :)

Kim

Agreed! No bosses or walkway: decision made.
Sorry Sam!😇

More on The Guvnor's Balls!

After three hours of close, detailed work, and if you haven't ruined these two tiny pieces of metal through an inadvertent file stroke or argument with a polishing spindle, or dropped it on the floor, never to be seen again, you might land up with two like this...
BTW I abandoned the idea of the bosses, just too fiddly!

Two 3/16" filing buttons, used both ends.



Both ends rounded, now held in a large toolmaker's clamp to profile the edges. I took them over to the Proxxon to finish sand them.



Two little darlings!



Of course, the drawing doesn't show enough clearance on the carriers for the link ends, but that can be fixed easily enough!

Nice work John.  :ThumbsUp: :ThumbsUp:

 A very elegant and pleasing curved profile.  The Victorians had an eye for style.

Excellent work - and I just learned a new technique. Filing buttons - never occurred to me before as a means of getting a good radius like that.

The Guvnor's Balls are in the Air! (Edited :LittleAngel:)

I've had a few projects in the air in my time but none were this tricky!

As per drawing. The pivot shafts are temporary...



On the machine. Oooh I'm chuffed!

Thanks for the compliment.  BTW I'd never heard of filing buttons either until I retired and started serious ME work, and I'm a time served fitter/machinist!

I love these Victorian style engines  and yours John, is a beauty.  Really impressive work.

It's not about the destination, not even so much about the journey,
but rather it's the interesting folks you meet along the way.

My thanks for the kind comments. I've been asked why the pivot shafts are temporary, and here's the reason. It seems that some builders omit these little pins, but I will be making them. If I had thought about it I should have made the holes slightly smaller and used 1/16" brass rivets! :facepalm:

Governor Actuator Arm

I made this little beastie this affy. Once again, it's a complete fabrication! The stirrup is a little long as I misjudged the curved length, but what the hell, it looks nice enough...



I cut the basic shape in the 2mm steel with the jeweller's saw. No milling and hacking for me!



Filing button for the centre boss.



Shaping the stirrup. Pure guesswork on the dimensions!



Silver solder paste to join the two parts.



Not quite to the drawing but it will do!
