Galloway 1/3 scale engine build
AZDesert:
This is my first post here about my 1/3 scale Galloway Hit and Miss engine build project. I will post some pictures of my progress so far and maybe a few questions for anyone out there that can comment to help me work out some details..
I started out with the base unit getting the top and bottom flat and parallel. Then made the mounting feet and made the pockets for them to fit in. I have made pretty good progress thru the small parts. I am currently working in the carburetor and wondering what is the best way to make the 45 degree needle valve seat. It is very tight space and I am not sure what kind of tooling would work best to do this without damaging the rest of the bore needed for threads.
I see another older thread that walks thru the same engine build but is there anyone else that had built one of these recently? It is casting kit from Ministeam that I am doing.

Good luck with the build, its' a good looking engine and I'll be following along :popcorn:

The parts so far look great! I've never built a hit n miss, but love watching them run. Will be following along... :popcorn:

Off to a good start, probably my thread you mention.
Of the several Lunkenheimer mixers that I have made I have always done the seat with a very small boring bar. Set the topslide over to 45degrees but have the bar set along the lathe axis or slightly angled to clear the threaded opening.

Yes Jason, That is the thread that i have been using as a guide thru this project. One other question I have for the carb is the hole/thread size for what i assume is the air intake port. In the attached picture it shows on the right hand side of the carb body a 1/16 -27 NPT fitting. It appears to be much bigger than that, more like a 3/8. Is this mislabeled or am i reading something wrong? The 1/16 size looks like it should be for the fuel line intake. Thanks.
