Wilesco D16 repaint
Davyboy:
Last summer I bought a rusty project from a flea market. (Like I need more projects!) At least it ran with a little air applied. There are a few parts missing, the governor, oiler cover, chimney. Well, I took it all apart, had to cut the steam lines as they seem to be soldered, locking the parts in place. Then I used a butane torch to get the lines out so I could reuse or replace them. I could not get the main steam valve out of the base, It seems to be held on with a nut, locked on with solder. We're just going to work around that. The boiler had a hole in the bottom (rust), and the fittings were rotted out, so the boiler is scrap. I don't want to spend any more $$ on this, so the decision to use the sub assembly and run on air. First pics of early in the process.

Then I gave it a bath in some paint stripper, which didn't touch the paint on the base, or the blue enamel on the guard. The black and the red paint was removed. Once everything was cleaned up, I primer coated white, then finish colors. The rods got red brushed into the recesses, cleaned up the edges with a fingernail scraper. Had to redo the black cylinder stand, the first try was bad. Note the broken stem on the inlet valve, knob is missing. Soldered the supply tube back in under the valve, blistered the new paint-doh! Oh well, fixed it once already, again should be easy. Made up an oak base, milled a pocket for flywheel clearance and a pocket for the supply tube to exit on the side. (no photos unfortunately) I did this work on the mill with a 2 flute ball endmill, 2000 rpm. I worked pretty good.
Davyboy:
Finally got it all together, after about 4 tries, I got everything onto place... Dinged the paint a couple of times with the screw driver, more touch-up work. I'm fairly happy with the final result. The new knob on the valve, and the plastic pipe look OK to me. I'll use a little Mystery oil in the air supply now and then, for the piston and bearings. Still not sure what to do with the governor stand in the middle, a conversation starter?

Dave,
Good score! I imagine I'll see it next summer at Badger steam and gas. Looks good!

Davyboy:
She runs pretty good at 10 psi, but it has a rod knock. I made a bushing for the big end of the con rod that tightened it up and made it a bit quieter, more oil helps too. She's still a bit louder than I expected. The D16 model reverses by manually turning the flywheel in the direction you wan it to go. There's a concentric slot in the eccentric, 180 degrees long, and a pin in the crank disc that drives it. Slick setup.
