Minnie TE Long term project

Joe d:
Aye, you're right about that, Rob!

Carved the motion plate saddle out of a bit of brass from the "come in handy" pile...

Nearly all rotary table work: this is ready for the final pass with a ball-end cutter to make a nice fillet, then flipped it over and did the same thing to the other side


Used the wood cradle to hold the boiler for drilling the mounting holes for both the saddle and the cylinder in the drill press


and here they are bolted down in place.

Joe d:
got going on the connecting rod and it's various bits...

Turned the rod, put a purely eye-ball taper on it:


cut out the strap for the big end


Turned and threaded  some brass for the oiler, then drilled it through


Turned, drilled and tapped the oiler cap, then knurled it and parted it off


Here's all the bits, neglected to take any photos of building up the cross-head, it's 2 plates of steel soldered onto a central bit that has a relief for the small end of the con rod, with a turned, threaded, and hardened pin of drill rod, and straight-forward turning for the bearing bronzes


and here we are:

Joe d:
Started working on the bits for the reversing gear...

Mounted a bit of O1 steel on the rotary table to mill all the arcs


once done that, just hack-sawed them out, and cleaned them up with some filing, using the ancient hand vice to hold the
die block for clean up before hardening it


pre-drilled a number of stubs of round stock and then silver soldered them into strips of  flat stuff to make the various links,
turned the clevis for the valve rod, milled the slot in it and used some filing buttons to round over the end, and turned & drilled a bronze
bushing for it, and here's the family shot:


and here is the test installation


dug out a stub of CI from the left-overs pile, and turned the eccentric sheaves, here is clocking in for the off centre hole for the shaft


parted off, cleaned up, and drilled & tapped for the set screw


and a start on the eccentric straps:  sliced a bit of steel, drilled for bolts on each side, then in the lathe to bore the hole,


and starting to file off all the material that doesn't look like an eccentric strap


Neither of my boys was here for the holidays this year, so I'm getting a useful amount of shop time instead...

DMIOM:
Joe,

Just to say thanks for posting, I'm silently watching and admiring the drama-free way you're cracking-on with this.
