What David said + keep posting pictures - great thread.

So here is the gypsy engine cylinder installed on the side of the fire box inside the cab and the cross head outside.  The connecting rod is three pieces of mild steel and the wrist pin is a trapped clevis in between the cross head rails. There was no space for any screws or like that.

The fly wheel is a made from a throttle plate from an SU carbureter from a 1959 Volvo that I had years ago.  I save anything that is brass.  The soldered closed screw holes won't show once painted.

I still need to make the yoke that holds the cross head rails.  Next part on the list.

The valve gear for this is really easy as this was a non reversing winch.  I can't figure out how they would have used the winch effectively when it only turned one direction.  They must have had to move the entire locomotive into the load to slack off the cables and then pull it out manually.  Had to be pretty exciting with a coupla ton log on the other end of it.

Are you sendin' them 'check-back' doctors these pictures to show 'em the kind of
creative surgery you're capable of??

Dave..........

That is really funny........  I do have one doctor up there that is interested in this stuff and always asks.

But otherwise it is pretty much doctor business with some serious blinders on for other discussions.

This is serious craftmanship. Nice to see these skills still exist in this draw it and print it age. Not that I'm against 3D printing per se but personally I can't quite get my head around drawing something on a CAD program then producing the result on a machine being classed as modelling.  I guess I'm just a dinosaur.

Here are two photos of the valve gear for the gypsy engine.

I had this urge to make it work.   

The bell crank in the first photo shows the bell crank to the valve on the cylinder.

The second photo is the back side of the fly wheel with the cam mechanism.  The two 0-80 screws are the cover plate that holds the connecting rod for the cam in place. The total throw of the cam is .100"

Just to make thangs clearer - GOLLLEEE, GEE!! That's some faincee faburcation there!!! 

Note: The Ledbetters spent about 3 hours lookin' thru their tatttered dition, dikshun, oh, hell - word book to
find that 'faburcation' word.  You can tell that they are impressed - they hardly ever spend that much time
with their heads in a book!!!

So the winch is most of the way done.  I have two little support brackets that come down from the upper shaft to the main shaft bearing caps to keep the location of the two gears so that they cannot walk over each other.

The capstans are turned down from 3/4 bar stock with a stepped shoulder inside that locates the capstan on the shaft and allows it to be held in place with a single screw from the outside end.

The fair lead pulleys are for aligning the pull of the cable while logging so that the cable cannot walk off the end of the capstan.
