I got my prints from Chuck. David is getting me the prints. If pages are missing I'll get them out, but I couldn't see anything that wasn't there? I was going to talk to him about serial numbers also)

When I read the part about the numbers, I thought he said they would be assigned after each engine is running.

I thought I had posted earlier offering to do the flywheels. I don't see that post now, apologize if it shows up twice. What sort of material and how many engines are we building again?

Question reading blueprint (HHM1-13):

The pushrod lock nut is a 3/16" brass cube drilled and threaded 6-32. It seems that there should be a round "collar" around one end of the threaded hole around which one end of a spring rests. However the plan states "turn to .235 diameter". Is this a misprint (should be .135), or am I misreading something?

Also, can someone explain why the dimensions on the pushrod bearing are in red?

+2 to how many team members. So 12 members +2. 1 for each member, 1 for HMEM to display at shows and 1 to sell for website support or charity.

The display model will be available to all members who go to shows.

I think I will be able to tackle the start lever plus something else..... I fancy the carb but I think it may be out of my league, although we do have six months or so....

If nobody else is lining up for them, I'll do the points, they look interesting.

Joe, What are your plans on the tungsten contacts for the points? I had looked them over and wondered about 1/8"dia TIG welding electrode. But I'm not sure how that would cut the 100% is super brittle. The 2% thoriated (sp) is not as bad. But if those options do not work I have tons of tungsten scrap at work. I can get a few pieces of. It is 92% pure machines like cast iron. I think the 2% would probably work best but let me know.

Does anyone involved with the team build already have a running IC engine Reason I ask is I built a transistorized ignition a few months back. It worked well on my test engine (junk yard two stroke) but I was never able to test it on an engine known to be a good runner. Problem I had was with high RPM but the carb was shot on the engine. If anyone has any ideas PM me.
Tim

I was figuring to go to the local UAP/NAPA and ask if they stocked them... If you've got access to some raw stock I'd happily work with that! Next question is how it solders, figured on some experimenting to see if soft solder would work, or if it would have to be silver soldered.

Cheers, Joe
