Lots of bits to make up the governor assembly so plodding through those, first was the base which was straight forward followed by the arm casting which was much more complicated.  Started by machining the main bore and then glued it to a length of steel for all the remaining ops.  Used the indexing head to spin it backwards and forwards to attack it on multiple sides.  Once it was finished a little bit of heat broke the bond and it fits nicely on the base.

Next part was the governor frame, a tricky little casting that helpfully came with two chucking stubs so I turned these concentric with one another and then flipped the part end for end in the dividing head depending on the machining op.  I then removed the stub and bored out the centre followed by some fiddly milling to cut the slot and the central windows.

The slider was a simple turning job - I first slotted the end of the bar and bonded in a piece of square bar to form the Tee section before cleaning it up in the lathe to final size.

An assembly of the bits so far.

Nice work.  That mill is good kit for parts like that,

Thanks Kirk - still learning how to get the most from the mill.

Today's job was the lever arms, bit wasteful on material but coordinate milled and drilled them out of round bar again using the dividing head to access all sides.  The parts were then hacksawed off the bar and filed to tidy up and radius the corners where required, couple of tiny brass rollers turned up to finish them off - most of the detail will be hidden inside the frame - ho hum!

Simon,
I am following your Corliss build closely and enjoying it very much.  The governor looks wonderful. 

When designing a model, it is easy to loose track of how challenging some of the small intricate parts can be.  Thank you for posting so many details and your thought process for making the parts.  They are very educational for all of us.

Thanks Dennis!

Next up was the Y shaped linkage that transfers the movement of the slider to the lever arm.  Spinning the assembly by hand it seems to work at a reasonable rotational speed so I'm hopeful it will function properly on the model.

Thanks guys.

Finished up the governor gearbox so could fit it up to the main frame to see how it looked, also cut a hole in the base board for the flywheel.

Hi Simon,
Your model is looking great.  I am especially impressed with the work you did on the governor and flywheel.  As far as I know, no one has machined the flywheel with the original detail like you have.  Great work.  Really looking forward to seeing how it runs.
