Well... seems it's been a while. Few bits of life getting in the way of shop time, but it's getting back to normal now.

Picked up with the water pump;

another bit of not-quite on pattern making left one of the bolt holes for securing the pump to the boiler hanging out in the air
so I counter-bored it,

and soft-soldered in a bit of round stock

sawed off the excess, and ran the flycutter over it all to even it out. You can see the result here, where I am drilling the flange for the
gland using the gland to spot the holes

then filed down the flange to match the gland, made up some bronze bolts and some simple turning of some stainless
for the ram

and here it is in place

The pipe unions and the square headed valve cover screws were made up of some bronze, this occasioned some delay as the die I used for the unions broke threading the very first one... the new one works just fine...

Started on the eccentric strap earlier today and buggered it already, so will start over tomorrow.

Cheers, Joe

Joe d:
Well, second time was the charm...

Set up in the lathe for boring out the centre...(never got this far on the 1st attempt, I'd split the material and then drilled
for the fasteners, and went off all squint with the holes, nothing matched up. This time I drilled first and then split the
material, cleaned up the mating faces and carried on)

hacksawed off most of the waste, then cleaned up in the mill

some sawing, filing, and drilling for the arm and then riveted in place (I had turned the eccentric when I did the ones for the valves)

And where it all goes

Joe d:
Made up the valve for the tender tank feed to the boiler pump...

first turned various bits from bronze

silver soldered the inlet & outlet pipes to the valve body, then into the mill to drill and tap for the valve top, which is internally threaded for
the spindle

Then drilled through the inlet and outlet pipes, that I had not yet through drilled when they were soldered into place

and then some straightforward turning and threading of a bit of stainless for the spindle, which then had some piano wire soldered on
as an extension so that it will reach over the top edge of the tender. Once in place, and with the brake handwheel assembly installed,
the end of the extension will be bent over to horizontal to act as a handle

Cheers, Joe

Joe d:
Bent up a little bracket from some brass, tinned the back face, drilled the tender and applied a bit of flux, and secured it with some scale lag bolts that cheerfully acted as self-tapping sheet metal screws.. which were well coated with flux before screwing into place.
Then gently heated until the soft solder flowed. All that as I neglected to realize I had this bracket to install back when I was making the tender,
where it would have been less worrying that I might bugger the seal in the tender's bottom joint with more soldering...
From the outside at least, all appears well

Threaded the end of some steel rod, and then using the collet as a depth stop (which you can't see on the other end of the vise), machined a flat on opposite sides, and drilled through to fit
the extension on the valve spindle

Cut the above from it's parent stock, rounded the cut end, drilled the tender side for it, and here we are:

Really starting to close in on the end now!

:clap: :clap: Looking great Joe :thumbup:

I am looking forward to seeing the engine complete .
