Hello,
I just managed to build a new rotary. It's nothing unusual. It's based on a few older designs that i saw done by some great builders.
This one works really nice.
The motor is a 17 mm maxon re-max motor that many builders are using.

I noticed that for some reason this machine is a bit louder than the other machines specially direct drive machines i've built. The noise is very similar to the Shag built rotary or a dragonfly.
I tried to find the source of the noise and it seems it's coming from the motor. I noticed that the motor shaft have a movement if i press up or down on it so the noise is coming from that movement.

My question is, what should i do to minimize the noise?
ANother question that i have is if there are some specific methods of mounting a ball bearing into a housing or a shaft?
I'm self taught in all the aspects of the machine building and machinery and there are a few things that still give me some problems.
Thank you very much.
