Steel is fine for the flywheels. No need for brass.

I ordered the brass for my parts, and I should have it next week.

I also showed the plan to my shop teacher, and he pointed out a minor "problem" with the push rod. The diameter of the rod (.125") is less than the major diameter of 6-32 threads (.138"). Therefore a 6-32 die will cut incomplete threads on the rod.

OTOH the major diameter for 5-40 threads is .125", so I'm wondering if all of the holes/threads for the pushrod/nut/follower should be 5-40.

Ideas from the group?

I may have found the answer to my own question. Seems most tap&die sets with 4-40 have 6-32 as the next larger size.

Is it too late to become involved? I would really like to be part of a team build sometime soon. Did I see that the cam is not allocated? I don't know how complicated it would be but am willing to learn..........

Mickey,

You want to take the cam? how about the arm too? If you want, we can add you. Let me know.

GULP! I just hope I can live up to the task but I will certainly give it a go! Can you email me the plan for the part? I will make a final commitment when I see if I am up to it, but I am certainly willing!

Also can you private email me with the numbers and how it all works (the team build process)?

Mike

Thanks for the plans, I will have a go at the cams if you like. Can I leave the arms for the moment, I want to be sure to complete what I start. If I get on well and no one else is doing them at that time perhaps we can revisit it then?

Mike

By adding Mickey everyone needs to increase the number of their parts by 1. Luckily I made extras of mine!

Nah, he can be the recipient of the 'show' engine.
