    Now for the weight arm. First drilled the pivot hole, two 1/4" holes, and spot drilled the center point of the small rounded end. Milled the flat portion. Mounted on the rotary table in the mill using a pointed spud to locate on the small center point. Then rounded over the small nub...

    Thanks for the comments guys. It is a relief to finally have it running. Now onto the governor parts. First up is the yolk. I found a chunk of 1 1/2" aluminum in the scrap bin just long enough to make it out of. After turning a small chucking register so that it will fit in my 3 jaw chuck I...

    Alright, ready for the first run attempt. Set the ignition timing to a little after TDC. Carb needle valve one turn out. Spin flywheel by hand a bunch of times. Nothing. Open needle valve another half turn. Spin by hand. Nothing. Another half turn and hand spin, still nothing. Arm...

    I am going to use an electronic ignition with a hall sensor. Here is the magnet disk before locktiting the magnet in and the hall sensor mount. I used heat shrink tubing to attach the sensor to the mount. I also completed the spark plug. I hooked it up to the ignition and I am getting a...

    Here is my next part. Within this Swiss cheese looking chunk of brass is a rocker arm. I drilled a hole at every inside corner and on a tangent line of each face. First I milled the side profile. Then I used drill bits in two holes to locate the piece at the correct angle to mill the first...

    Brian, Gus, and Swifty, I am aware that it isn't a good idea to use the same materials on sliding parts. I didn't give it a thought as the plans call for brass for both parts. I am going to leave both pieces brass and see how it goes. Worst case scenario I that I have to remake both simple...

    Thanks again Brian. You have mentioned in some of your build threads that after a while it seems as though you are posting in a vacuum. I think that this thread is at that point. I only have a few more parts to make before I can try to run it (not in hit and miss mode), then things should get...

    Here are the push rod bearing and push rod.

    Next is the cam slide bearing. First I drilled a 1/8" hole for the inside radius of the corner. Then mill the profile. Mill the slot. Then drilled the mounting hole. I had to use a center drill for the countersink as my countersinking bit is too wide to fit in the slot. After rounding...

    Up next is the regulator arm pivot. After turning to size and drilling/tapping the end to 6-32, I mounted it in a v-block and drilled the hole for the pivot pin. Then rotated the v-block in the vice and milled the slot. And here is the finished part.

    Up next is the big gear. I deviated from the plans a little and made the gear and cam one piece. I started with a chunk of 1 1/2" 12L14 round bar in my 4" four jaw chuck. I turned the end down to 1" so that it will fit in my 3" three jaw chuck. After switching to the 3 jaw I turned the...

    Today was another first for me. Today I cut my first gear. I must say it was fairly easy. I bought a set of Mod 0.8 cutters from CTC Tools. I went with Mod 0.8 as it is close to the 32 pitch that the plans call for. First I turned a chunk of 12L14 to the proper dimensions. Then without...

    Going to build my first engine!

    Excellent looking and running first engine. For your next one I would suggest one of Elmer's engines. There are lots to choose from and many are good for beginners. I have built six of them so far with more to come. Plans can be found at http://www.john-tom.com/html/ElmersEngines.html.

    Thank you Brian. Today I made the rocker arm pivot. After milling the stock to size I milled out the profile. Then drilled the mounting holes. Then drilled/reamed the pivot hole. When a hole crosses a slot I like to drill the hole before making the slot to keep the drill bit from...

    Thanks everyone for the compliments. I am glad you are enjoying the build. Progress has been slow since summer is here. I got the second flywheel done which should be the last of the larger parts.

    With summer here I have not had much shop time but I finally completed one more piece, a flywheel. After turning to size I used the rotary table to mill out the recess. I prefer to do this on the mill instead of the lathe. Then drill all the holes that make up the inner part of the spokes...

    Where are the pictures?

    I don't see the pics with Firefox, but can see them using Internet Explorer on same computer.

    Where are the pictures?

    I also am unable to view the pictures on the linked thread. Usually when pictures are missing from old thread the poster has either deleted them or more likely renamed or reorganized them on the hosting site (ie. photobucket). This wouldn't explain why some can and some cannot see the pictures...
