OK I finally have this pretty much functionally finished (I still have some little details to attend to.
Platter rotation motor is a $20.00 Black and Decker 3.6V rechargeable electric screwdriver Motor and planetary gear reduction (180RPM stock). Power is transmitted via a Hub drive using a 1.5" diameter Model airplane rubber tail wheel shoved over the bit holder chuck on the screwdriver motor and riding against the plate belt pulley surface.
This combo gives so much torque I could use this to screw a 2" wood screw into solid fir! It is a 6-1 reduction from the original 180 RPM. The reduction increases the screwdrivers already massive torque.
The Vacuum turbine is from a hand held Euro vac.
Motor power is from a 5V 3.7amp wall adapter using 3) pairs of N4001 power diodes to reduce the voltage to approx. 3.8-3.9V volts giving a speed of 29-30 RPM I would GREATLY like to THNAK Markthefixer for this excellent solution to my hair pulling power supply problems.
The Platter and bearing assembly is from a mid 70's era ONKYO TT. I had to make a special tip for the spindle so I could have threads on the tip for the clamp to attach to.
The Mat is two layers of the finest grain cork I could find glued together with Carpenters glue.
The Vacuum turbine is housed inside simple cheap 4" PVC sewer pipe it turned out to be the perfect inside Dimension. The front 10" of the big white tube is a Water trap that seams to be doing it's job very well I can't feel any moisture exiting the rear of the machine. I still need to add a 1/8" diameter brass tube into the water reservoir so I can use a large syringe to suck it dry when needed.
The Vacuum pickup is made from .750OD Carbon Fiber tube and the pivot blocks are made from Micrata (a Phenolic resin and cloth based material) The slot in the pickup is shielded with Velvet ribbon carpet taped to the pickup tube I used about a 1/16th inch wide slot.
The platter will rotate both directions. (I need to reverse the switch as it's mounted wrong!)
It takes approx. 2 rotation to remove all visible liquid from the record.
I tried to make the styling look like it fit my Oak and silver face system. I still have to finalize the satin finish on the aluminum but wanted to make sure everything worked properly before those details.
The box is 1/2" MDF that once it was glued and screwed together I used 20 minute model airplane finishing epoxy (think the epoxy version of a polyester resin like fiberglass uses) This fills all the screw holes and toughen ups the edges so they will hold up to years of being rubbed. The Paint is Rustoleum Hammer finish black and one more coat will go on once I decide to complete the finish details.
The surface of the top is covered with Black art foam about .090 thick.
So far I have only test washed a few records to see if everything is working properly. I need to pick up some more distilled water for a final rinse and then I'll do some serious testing and test listening to see how well it is working.
I still need to pickup the new inner sleeves and jacket covers I want to use before I start cleaning the collection. But that will give me time to perfect my method cleaning thrift shop junk.
Feel free to ask any questions I'll come up with something.
