Sorting the electron path from the tender to the loco, hidden under the 5mm high cab timber floor boards (to be made later) to the servo mount then to the receiver up front in the tank via 4 x 4 x 0.5 Knupfer brass tube. Tidy, facilitates maintenance/repairs. Just fitted after much head scratching, cutting , filing and soldering and test runs. I will be using 22 swg silicon wires and JST connectors (and these do fit) The white bell wire is just for the pic.

An evening of shortening servo wires, fitting new Futabo connectors. There are constant mutterings emanating from Captain Plod, "Must finish this loco, must finish this loco., must finish ....." This electron stuff I think it is all simply witch craft and should be avoided if at all possible.IMG_7094 by Darrell McCulloch, on Flickr IMG_7096 by Darrell McCulloch, on Flickr IMG_7097 by Darrell McCulloch, on Flickr IMG_7099 by Darrell McCulloch, on Flickr IMG_7100 by Darrell McCulloch, on Flickr IMG_7101 by Darrell McCulloch, on Flickr

A crown level plate, what a good idea

A crown level plate, what a good idea It is not needed with a 32mm gauge coal fired garden steamer, as soon as the water is gone, the fire dies in 20-40 seconds,and there is no blower to sustain the fire if you stop, so the fire is lost very quickly. A lot of testing has shown, contrary to common belief with the little locos no damage will result because the heat source is gone so very quickly when the water is gone. The coal fire cannot be sustained. When one stops you have to get the blower on with 30 seconds or the fire is lost . Gas fired is very different, I just put it on there for kicks and giggles. It is soft soldered on with 243c solder. Could be my lead plug equivalent :-)

Although not to be encouraged, I have seen a few 5" gauge boilers boiled dry with no damage provided that they are fully silver soldered. I leant one of my engines to a young bloke one day and as he came into the yard the engine was blowing off and suddenly stopped with no pressure on the gauge. It was bone dry and when later inspected there was no damage and the engine has been used many times since with no problems. The boiler code ,if followed results in a very safe boiler.

I was at a railway in the 1980's when some one lost their water, they all rushed about to drop the fire. No one thought to cap the chimney immediately and then fuss over about the fire.

First time the smoke box door could be closed with the boiler attached. Currently linking servos up to twitch. Whistle was linked while listening to the 5th Test in Hobart.

Connected the blower up, it twitches. I am not confident about the actual valves. I will not be surprised it I have to remake them with an O ring seat design which appears to be better for servo control. I would have done that from the start if I knew what I know now. We will see when I test steam.

I was keen on the Queensland Railway, Hunslet style of cladding corner in the cab. I was not sure how but it come to mind to use brass tube. It worked out first go. Turned a former for my tube bender. A wee bit smaller than required as the tube will spring a bit.IMG_8533 by Darrell McCulloch, on Flickr Annealed the 5/16 tube a few times. The formers are such it captures the whole the tube and thus it does not distort or flatten out. IMG_8534 by Darrell McCulloch, on Flickr I was too engrossed to take pictures, but I scribe/marked the tube and used thin Dremel cut off wheels in my die grinder to slice the tube till I had a 110/120 degree corner left and then cleaned it up on 400 grit on a small surface plate to give two straight edges. Then fit and 12BA screws to the crinoline ribs. 14ba would look better but I am not yet set up with 14ba in the Red Room. I must sort that out soon. Any how, it is a freelance garden steamer, not a exhibition model.IMG_8540 by Darrell McCulloch, on Flickr IMG_8541 by Darrell McCulloch, on Flickr IMG_8566 by Darrell McCulloch, on Flickr To be polished properly when I reassemble.

Goodall valve. LG2 bronze. Quad ring trick to hold the domes. Quad ring is a four sided O ring. I ripped this idea off from MAM's Roundhouse loco. It suddenly dawned on me why they put O Rings on their boiler bungs. IMG_8568 by Darrell McCulloch, on Flickr Bench tidy up, make a list of what jobs are remaining to be knocked over. IMG_8569 by Darrell McCulloch, on Flickr Tool Box fitted in place.IMG_8610 by Darrell McCulloch, on Flickr ]So the whole cab and thanks can be removed without anything being disturbed. This is the by pass valve. I am not confident the actual valve will work satisfactorily , I maybe remaking this after steam testing.

Beautiful craftsmanship as usual. What a charming little Locomotive this is! Almost there!
