Engines > Your Own Design
The Webster Chicago
maury:
Continuing on in the shop I decided to check out the head casting. For this I needed to break out my rotary table
which I haven't used for many moons. Drilling the water passages is a bit tricky as the holes need to align across
different setups, so special attention is given to precise alignment in the setups.
Dave Otto:
That is looking like good progress Maury!
I didn't realize that you were working on a Fairbanks R, or I didn't remember. Are these PMD castings or your own?
I noticed that on one of the tables at the Cabin fever show video there were some R castings that apparently someone is working on making.

maury:
Dave, thanks for tuning in. Yes, I'm building a Fairbanks R 3 cylinder. About 8 to 10 years ago I bought the prints for this engine from Bob. I've always wanted to build this engine, and when PMD imploded I just set them aside- plenty of other projects. I made patterns and aluminum castings in my foundry, and after about a year I now have an almost completed engine. Next step is to powder coat it before final assembly.
The patterns went to a friend who is interested in producing the kit. The drawings have been redone in Solidworks, are completed and checked.
When I get my iron set of castings, I might do a build log
maury:
Time for an update. I have machined the intake section as much as I can at this point. Still waiting for the iron casting for the exhaust and hot tube which also connects this assembly to the engine.
maury:
I had some more shop time this week, working on some of the general assembly parts while waiting for the iron castings.
The needle valve is for controlling the gas flow for the hot tube. Since I have little experience with hot tube ignition, I may dummy up a hot tube system to sanity check my design before cutting on the casting.
The latch out assembly is complete now, and is waiting for the flywheels assembled with the governor balls.
I have word that the iron castings will start trickling in soon.
