Would using one of those ultrasonic units be the answer

for cleaning?

If your displaying this one I would find it hard to cover it with paint. Nice

 

We're those originally painted? So pretty just polished.

 

I haven't been painting the engines that I've built in brass.

Might be.   I'll have to check into that.

Working on mounting the pilot and making up the deck plate on the front.

The framework for the deck is soldered to the underside of the deck plate.

Drilling a .040 diameter into the end of a .062 diameter brass rod.

The air pipe fits into the hole in the brass rod and is soldered in place.
Then the brass rod is bent to shape.

The air line is then mounted to the top of the deck plate with two "U-bolts".

Good to hear no paint on these. Looking real nice Ray. Drilling that hole looks interesting. My Dad now retired was a machinist for the Dover Corp. He always kept me supplied with drill bits because they would never sharpen anything just throw them away. He once gave me a piece of tape & said here's a drill bit. I opened it up & honest it looked like a fine hair. I had to look under my magnifier to actually see it was a drill bit.

 

Your project is a good one to follow & to know how much we all have many interesting talents, skills etc. to share.  :thumbs:

You must not have much run-out in that chuck. Working on little stuff like that won't tolerate much. Is that a 3 jaw independent chuck?

not seen one like that.

The lathe is a Sherline  model #400 and the chuck is dead on.

Turning a piece of plastic down to make the insulating hub for the leading and trailing truck wheels.

SAM_0325_zpsnsgiukav.jpg


The wheel is pressed onto the plastic hub.

SAM_0326_zpslnjh1kgd.jpg


With the wheel then clamped in the chuck, the back of the plastic hub is faced off and the hole is drilled for the axle.

SAM_0327_zpslehwevtp.jpg


Two of the wheels have the axle shaft pressed in place now.

SAM_0328_zpscfrp4sjn.jpg


Here are the finished wheels.

SAM_0329_zpsinguikat.jpg


The frame for the trucks is cut from a piece of sheet brass.
The axle shaft for the wheels fits nicely in the piece of small brass tube.

SAM_0330_zpsac0ayvn2.jpg


The sides are bent over to make the truck frame ridged and give it some thickness when viewed from the side.
The front lip on the truck frame is also bent over and the small brass tube is soldered in place.
There is a small hole drilled in the top of the small brass tube to oil the axle shaft.

SAM_0334_zpsamkxpgan.jpg


Here is the finished leading truck mounted on the chassis.

SAM_0333_zpszkpfx91x.jpg


This is how the chassis looks so far with both trucks installed.

You really operate at both ends of the spectrum don't you. From installing a Cummins in a truck to installing trucks on a locomotive. Amazing. Next you will be carving the Constitution on a fly's wing.  :smilewink:

Truly a talented man. I like just watching him work.

I can't wait to see the fly wing thing happen. :smilewink:

I thought that I was going to be able to purchase a smoke box from PSC but they didn't have any with a large enough outside diameter.
So it looks like I'm just going to have to build one.

Starting by turning down a brass bushing so it fits snugly into the front of the boiler.

SAM_0337_zps28gxgmz9.jpg


The bushing was then cut in half so I have two support rings for the smoke box.

SAM_0338_zpsxs0n72t1.jpg


Then I cut a strip from a sheet of .020 thick brass and bent it around a piece of pipe to start forming the shape for the smoke box.

SAM_0339_zpshpswb3jb.jpg


The brass strip is wrapped around one of the support rings.
This ring sticks out a little and will be the part that fits into the front of the boiler.

SAM_0340_zpsqkjahk1d.jpg


Both support rings are soldered inside the brass strip to form the smoke box.

SAM_0341_zpsjwldrnzd.jpg


The smoke stack and the boiler front are soldered in place and the finished smoke box is soldered onto the front of the boiler.
The hinges, hand rail and engine number were missing from the boiler front so those parts were also soldered on.

That looks better!  Can't wait to see it with wheels under it!
