PostSubject: Balancing One tooth drum   Fri Mar 15, 2013 12:50 pm

We have designed and built a one tooth drum, it was perfectly balanced on the software but when we got it back from the machinist it is slightly unbalanced. I was just wondering what others have done in the past to balance their asymmetric weapons.

Depends on what you mean by 'slightly.' I probably would just run it and see what happens.

Its slightly off balanced by when you put it on the table it wants to roll toward the opposite side of the tooth. But when we spin it up it goes to around 8000 rpm were hopin to get more out of it by balalncing it and were wondering what others have done.

Would they be able to do it if its solid steel? With two small holes towards the tooth.

After calling several shops and only finding one who was capable of doing it then telling us he wont because of liability issues we found a way to balance it better. It currently weighs 5lbs at 2in in diameter and spins at 8000k rpm I feel as if the rpm is low, was hoping for more of 16000. Were using the fieago 540xl 1:1 and i feel as if it should be more.

It's the fieago 540xl and I believe it's 1490kv off the top of my head and its 13.2 volts thru it so the motor should be 20000? With no load or drag
