I am aware that noise is an issue with most users I will address it as thing I get feed back as always. I will be adding a nitrile washer to the disc that you can see in the picture I am hoping this will do to things first deaden the noise slightly and secondly provide some give. I will then supply several densities of washer so you can choose the amount of give you want in the machine.

I intend to redisign all of my machines in the next few months so that you can choose the motor you want and then just buy the front end and fit them together. You will have a choice of 4 motors, 2 German 7.2 volts and 2 Swiss 12 volts running from 21,000 rpm to 8,500.
