This is a new build in a scale that I am not used to building in.  1:50 scale.  Exactly half of 1/25 in overall size.  But this Mack L pumper had a Snorkel worked into it so we are giving it a try in brass.

More study that actual engineering I think.  Fortunately I have the photos but I also have a 1/32 scale Franklin Mint Snorkel that I can also look at and see how thing work together.  Once I got started much of it came together quite smoothly.

Got some more work done.  The basic construction is done.  The waterway is complete to the basket where a deck gun would be mounted.  The base of the snorkel has been screwed to the bed of the new body from the bottom.  The rest of the base work can now be done knowing that it fits snugly into place.

To get an idea of how the model will look I set the new body behind another Mack L and then took the photo at eye level.  The boom appears to be lower than the beacon on the top of the Springfield windshield but I think that is just perspective with the boom being in the background.  Getting closer to paint time but not yet.😉

More work completed on the Snorkel.  The base is completed and the riser for the deck gun has been extended.  It's almost ready for paint.   The base will be red while the boom and turntable part and basket will be white.

Wow, that’s a whole lotta brasswork! I think you’re crossing over to the Meccano side of modeling, or more correctly model engineering! Looks like very precise fit of the many parts, such neat soldering and everything works too, pretty fine work!

Yes, a lot of brass but it has been a fun project so far.  Figuring out what to solder and where has been a bit of a challenge but it has worked.  A small amount of work left to do such as the braces for the long sections of waterway.  Then I think it is close to being ready for some paint.  The biggest problem I have had with brass is that it does not hold paint that well.  It tends to chip and wear easily.  I've tried etching primer but that is not foolproof.  I do have to plate the two hydraulic pistons but I have the plating solution for that.

Ever try etching with vinegar, did it not help give the surface some tooth? That was a thing with brass model railroad engines back in the day. Been disappointed with self-etching primer myself when used on Hubley diecast kits

The snorkel is done and has been delivered for eventual mounting on the back of a completed Mack L.  One small Deitz light has to be made for the corner of the platform but that's about it.

DUDE!!!! You have my attention with this one... Absolutely amazing work... Not only is it 1/50 scale, but you have tackled a snorkel unit in BRASS!!!  Man,... I am constantly amazed at your work.... I love die cast, so you're really speaking my language with this baby... Awesome!!!!!

Two last items were needed to complete my end of the project.  Two Crouse-Hind lights in 1/50 scale were needed along with one more Deitz light for the platform.  A master spotlight was turned from aluminum rod and a mold was then made of RTV.  Two resin castings were made.  The light bases are made of brass.  Bare metal foil was placed over the lens and trimmed.  Then each light was primed and given a coat of aluminum paint.  After the paint dried the BMF was peeled off to show the translucent (casting resin) lens.  A piece of thread was added to the rear of each light for the electric cord.  The Deitz light was made from 1/8" diameter brass rod.  The base and light itself were turned separately and then soldered together.  The light was painted silver with a white dot for the lens.  it will be mounted on the corner of the platform opposite the one already made.  

The spotlights are mounted on the pumper just to show the relative size.  On the final rig the deck gun would not be there allowing more room for each light.
