Now the part I don't like three hours standing in front of the 1978 bandit control program three different segments and then dry running them to make sure that I did not fat finger a number.

Finish part in the background is the bandit controller this is the most complicated part that I've done on this machine and hopefully the last I ordered three new stepper motors and drivers hoping to go to Mach3 if I can figure out how to make it work

Put some slots in the toggle bracket for the spring. I think this is a better design because the spring can be longer



Jeff
 
One spring now with the spring up close and tight and the toggle installed to the governor

First I should clarify that I have zero experience in the electrical field. having said that I was inspired by Ridders CDI switch and so I have to make one. I fried the circuit not having it grounded very well. Living in the US and not wanting to spend another $20 on a six dollar part I went in search for an alternative. I end up with the Home Depot flyswatter sapper with the coil from a different gas lighter. See link

Sorry for the slow build. Over the last four months I have doubled my income in overtime hours leaving precious few hours for self-indulgent midlife crisis hobby time.
Here is a video of my engine running with the Home Depot flyswatter circuit. The governor arm a little short so it clacks a lot but it still holds the exhaust valve open. This video is in focus and the real treat is you don't have to listen to me. Thanks for watching.

Just the gas tank and the electrical to clean up and I can call this finished.

This is where my journey begins. Back in December removing from closet and cleaning 19 years of dust accumulated it was time to finish this engine I first had to find the name of the engine and where to buy the blueprints which led me to HMEM. When I started this project I had a year and a half apprentice time as a machinist. When a machine was available My boss would let me stay after work and do what I could one piece part at a time. I missed the shelf of material for G parts and the ability to anodize and black oxidize my parts with a batch of job shop stuff. After leaving the Job Shop environment I went into the composite field and it would take another 14 years before I was able to start accumulating machinery of my own.



Okay here it is was a long journey for me. I have now earned a place on the wife's bookshelf. It feels so good to have it done. I've learned a lot along the way I have to say the hardest thing for me was the electrical. I can't tell you how many times I electrocuted myself. It was good for me to have a place to show my work and to have some accountability so thank you

It turned out real nice Jeff,

Way to stick with it.

Okay I need help CDI fry again I'm ready to give up big ugly switch buy a commercial CDI. What should I get?




Looking pretty not working




Jeff Hickenlooper
 
Thanks Brian. Ordered the buzz CDI. Can't wait to see it go again

Jeff---Take a minute and explain to me how the "gearless" aspect of this engine works please. I assume that the intake valve is atmospheric, so needs no cam to activate it. Normally, on a 4 stroke engine with a cam, the exhaust valve opens every OTHER stroke, so the cam activating it needs to run at 1/2 the speed of the crankshaft. Without gears to give this 1:2 ratio, how is the exhaust valve opening at the correct time managed?---Brian
 
Thanks Brian. I failed to mention that it was a four stroke. The heart of the engine is the exhaust valve pushrod and indexer. briefly put the up-and-down motion of the rod rotates the indexer located on top of the rod thus activating exhaust valve.

A short 55 second video for those you like me that are more visual. Thanks for following along

My diodes showed up before Roy Sholl CDI did. so I fixed the flyswatter circuit running on it now for three hours will change it out when it quits working. I do not recommend the flyswatter circuitboard but those who are brave should know that there are two different circuit boards.
ML-02/HT -- works
MLD06 -- will not work



Moving to finish projects thanks Brian and Dave for your kind words
