Well, I have been a member for a little while, kind of hiding in the background, I figured it was time to make my first post on the forum.
I have always been interested in anything mechanical since I was a kid. My first introduction to machining was when I was about 14, my Dad bought me a Taig lathe with milling attachment. At the time I was into RC Cars and used it to make quite a few parts for my cars at the time. When I got out of high school I went into the military and the small machining hobby was kind of left behind.
Over the past 12 or so years I have been doing welding and fabrication as kind of a side hobby. I figured if someone else can make it, then why can't I ! Some of my projects included a Garden Tractor Loader and Backhoe attachment. The backhoe project is what led me back into machining, I needed to make some custom bushings and pins. I picked up a 7x12 lathe and made the parts I needed, it worked out great. Since I now had a small lathe I looked into other projects I could do with it when the weather was bad and I was stuck inside. My first little engine was based on the Little Machine Shop wobbler, it came out pretty good and runs great.
Since building the wobbler, I have built a bunch of tooling for the lathe (boring bar holder, cam lock tail stock, cut-off tool holder .......) I also picked up an X2 Mini Mill and have built a bunch of tooling for it. The shop is setup pretty decent now and I have completed a few small engines. I built 2 of Elmer's Scotty engines, one for me and one for my Dad, both of them came out great and run nice and smooth. I can post pics/video of them if anyone wants to see them.
I currently caught the "Chuck's Horizontial Engine" bug and have completed what I am calling Phase 1 of the engine. It is smaller than Chucks original design, .600 bore, .500 stroke, uses 2" flywheels and is a 2 cycle version, as I didn't have any small gears to make it 4 cycle. It does use his poppet valve design, just a smaller version. The valve body was my first introduction to using 0-80 screws! I also uses a slightly different cam setup, which will hopefully help me when I take the engine to the next step. The engine is currently running and has the cool exhaust "pop" sound. I am amazed at how slow I can get it to run. I have pictures and a small video of this engine running also.
Now I am working on phase 2 of the horizontial engine project, I am trying to go the same route Chuck wants to go, and make the engine run like a hit or miss engine. I did some sketches on paper and am currently building new parts. Looks like it is going to need new flywheels, crank and of course a flyweight style governor. Hopefully it will work, but if not I can always take it back to the original version.
That's about it in a nutshell (kind of a large nutshell, sorry for such a long post!)
