Ah, Christmas eve... peace and quiet. Except that the heat went out in the shop. But while waiting for the propane fillup, got some good stuff done!
First, tackled the distributor and in timely fashion, my friend David Morrison did a great article on the RR "Pancake" distributor, which I thought I'd share here. As it shows in detail the RR Derby pre-war distributor. Hopefully, this will give you some ideas on how to finish and/or replicate.
Here are the original parts, and some pieces of ebony wood that I used to replicate the bakelite distributor parts. Some of them really tiny, when it comes to the points-adjusting knob around the perimeter.
In addition to making the new points cap, I replicated the air pump, which is, in essence, a fuel pump, pressurizing the gas tank to 1 - 2 PSI driving gas into the carb. Very reliable! I still have some finishing to do on the tower, mainly in the surface finish. And adding the nuts/bolts to the holes. The threaded 'studs' will take slip-on plug wire ends. If I get ambitious, I'll number it with the firing order 142635. One is at the front. Rotation is clockwise. Jeff... feel like an engraving project?
Here is another view of the distributor, and one of the water pump. Did a bit of re-shaping and then tinned it. The original pumps were tinned as they were sand cast bronze and could weep if not tinned. So I took the brass Armortek part and tinned it, then sanded off parts of the tin to expose the brass. Looks great!
And then we are back to the fan... which I finished today. When you get your fan hub from Dave Dibb... I suggest using epoxy. I used solder. Silly me. But read on. First, here is a real fan!
And here is a soldered-up 1/6th fan sitting on... a fan. The blades are made of shim brass, about .030 thick and 3/8" wide. I almost made them out of German Silver, to polish, but decided to use brass as most of the original fans were painted black. Though today, everyone wants shiny polished aluminum blades because they are pretty... the originals were almost always painted black. (And if you want to start a fight at a gathering of Ghost owners.. bring that up. But I have history on my side...) Anyhoo....
Here is a less-cluttered and close-up image of the same fan. The major PITA here was soldering on the blades... onto the soldered-on fan bosses. Want to solder something to something that is soldered.... be prepared to melt all your solder. Resorted to doing it in a bath of water.... keeping most of the hub submerged while I soldered the part 'above water' with a jewelers torch. Next time, I'll glue the damn things! The good news is that the hub pattern worked great, the prototype is on the way to Dave Dibb at Armorpax, who will create a Britannia version for everyone... and I don't have to solder vanes on again! Though I am rather proud of my soldering here.
And after all that, I went and painted it....
Well, at least you guys will know what went into it! Because noone else will, ever!
Tomorrow.... short day, but it is a tradition that I spend a few hours in the shop on Christmas Day. It's one of those things...
I should finish the Magneto, get the Water Pump shaft done.. and maybe the spark plugs final turned. The trick to turning ivory is very, very, very high speed!
Thanks for all the encouragement, too! I hope to inspire some other great builds, because I know some of you can take this to even higher levels!
Have a very Merry Christmas all my Armortek friends!
Cheers,
RPR
P.S. It's not Christmas until after Hans Gruber falls off Nakatome Plaza... Some of you will LOL at this
