Motor Unit Construction

Postby McGee2021 » Wed Jul 05, 2017 9:18 am

I have finally decided to 3d print the framing mechanism, and i have sent away files to laser cut sheet metal to make the 30 tooth wheel. But in order to do this successfully, ill need to use a double shaft, universal motor. I have looked and looked, but there seems to be an extreme shortage of them. I was hoping to find one similar to the one Denis Asseman used in his televisor replicas, but i have no information on it other than it was french made. Does anybody know where to source this motor? The Motor he used can be seen here: http://users.skynet.be/telehor/nieuwe_pagina_7.htm

The 150 ohm variable resistor came in the mail today and was about 1.5 times the size of what the seller stated! I have glued together the ceramic resistors, them being one 400 ohm, and five 60 ohm resistors.

I have finished 3d printing the resistance unit, and have printed off a bracket to hold the variable resistance. I am heading out tomorrow to get a piece of wood suitable for the base, and hope to have a base done by Friday.

I had the chance last night to get caught up on my part making, and managed to make the motor stand and 20 inch disc hub.
