Building the Lynx15

[Alan's Home Workshop]

Having recently completed my first engine, I decided to challenge myself with another design that is a bit more sophisticated - the Lynx15. This engine has an enclosed crankshaft and belt driven overhead cam. I bought the plans from Greg's Machine Shop and started building.

I think with the lack of messages everybody must be messaging you on youtube. I'm enjoying this build, good quality machine work and I like your thought process.

Great build! I have one of these on my build list.

Well I am making progress, but less of the three steps forward and one step back dance would be nice

Have been following your Webster and Lynx build series on YT.
Nice to see these engines coming together.
Thanks for sharing your work!

Thanks for your feedback Jim. I bought an S/S CDI kit and am now working out how to fit it. On the original Nemett engine the timing disk for the Hall effect sensor was located on a rear extension of the camshaft. However, in Greg's interpretation of the design, the timing disk is located between the front of the cambox and the camshaft pulley. Working out how to mount a sensor to read the disk in this location is a bit of a challenge as space is very tight. These screen shots show 3 options I am considering.

I'm not seeing a clear winner yet, so more head scratching will be needed

Can you recess the pickup into the face of the cam box cover that faces the pulley, so it's less obtrusive? Otherwise, version 3 seems like the easiest to install and adjust, but can you put the magnet in the pulley and skip the extra disk? You'll want to be able to move the pickup while the engine is running to set the spark advance.
