    John W, I would think you would just have to adjust for the cam gear position and pushrod height position. Changing the push rod height/angle may effect opening the valve. I'm sure somebody will have a better answer.

    Attached is a picture of the connecting rod and Piston. Could use some clean up and polishing on the rod.

    I did have a question on where the crank spacer goes. See attached photo. I believe it goes as in the photo or I did the wrong dimension on the cylinder head-frame.

    Well, now that I'm saving time by not having to commute. I machined a crankshaft today. I just made the simple one according to the plans. I used some stay brite silver solder. Hope that holds up.

    Outlet for model engines

    I helped a lady at work liquidate her Dad's shop(mostly older welding equipment and tools) a year after he passed away. I asked her what she thought everything was worth and they were expecting$200 - $300 dollars. I sold everything I could on a local classified ad site and she ended up with...

    Gordon, Thanks. It was very brittle. I'll try again on the next square hole. It was a little frustrating, but I know what to do next time. Jerry

    Then I went on to dealing with the square hole. I found a video on how to make a square broach. I made the broach using w1 drill rod, heated it cherry red, then hardened it using water. After drilling the hole, I tried to press it through, it just broke in pieces. I did something wrong so I...

    I've been busy, but had some time to work on the spring winder body. I had to tackle the Oval shaped hole with a triangle shape on one end. I not very good with Fusion 360 but I made a simple drawing to help machine the hole. Here is the drawing: I first drilled a 7/16 hole and the .073...

    Murph, Thanks for the info. I've been buying the 1/4 lb spools of music wire from McMaster-Carr. I leave the spool bundled and only take out what I need. Thought about buying some canisters or make something similar. Sounds like your in a good position to be the only guy winding springs...

    For the crankshaft bearing, I ordered from Stock Drive products. 5/16" I.D. X 1/2" O.D X 5/32" THK., FLANGED P/N A 7Y55-FS5031 There pretty proud of them but I liked having the flange.

    Spring Winder - Build your own springs

    I just finished up the pressure bolt, adjusting bolt and the friction bolt. I use my live center since the bolts are almost 2". I tried a different technique I read about in MEB magazine where you turn down the rod in sections. Then the last two passes I went all the way across. I have...

    Spring Winder - Build your own springs

    So, back to the build. I spent some time machining the adjusting bar. This was key stock that is zinc plated. Used a slitting saw to cut the notch. The other end was drilled and tap for a 4-40 screw.
