Hello Larry,
Yes Dan was winding arms during the Bicentennial. Dan was a "padawan" of Mr. Bob Green of MURA fame and so Dan had been around a good long while by then.
I recall my first try at winding an arm, I think it came as a kit and you wound it and glued the comm onto it and you had a start on a motor. I struggled with the concept as I am not gifted with manual dexterity and when it was done I saw were you could mail the arm to MURA and they would finish and balance the arm. Well I did not believe what I had done was all that bad, but MURA sent me back one of their armatures, brand new in the bag and as a very young kid I was over the moon. The end of my rise to fame as a motor builder...!
PS. Hello Mike I will do my best, but I have always found my writing and telling of tales bothers some people. I can only tell you that I do not intend to offend folks. I am in Sales and I had a manager once tell me "Chris, please do not respond to folks with an email, as apparently you can not see the brutality of your writing." I will do my best to re-read everything, but please if I get out of hand just cut me off. Sincerely, Chris
