Well Tempered Simplex arm and wiring

mr_m, it dawned on me that I could 3D print a similar connector to what the Amadeus ll uses to attach the ball and arm (why not make it more like the upscale model rather than the Simplex...).

Can you tell me a little about the piece that connects the arm and golf ball on the Amadeus ll? How deep is the entire unit and is it aluminum? Dimensions of the various surfaces would help. How deep is the lower circular piece and it's diameter? Is it curved to fit the ball underneath or is the ball itself cut in any way? I see a screw goes thru the top down into the ball before the arm slides in... Can you tell me the diameter of your tonearm? I've used a 6mm (slightly smaller than 1/4"d) carbon fiber shaft for an arm previously which worked well.

The silver cap is either aluminum or metal, not sure. It has a silver paint coat on it. The caps overall depth is 1 inch. The upper part of the cap is 1/2 inch, the part that holds the arm, and the lower part is 1/2 inch. The cap is approx. same dimension as a golf ball. Golf ball is cut in half. The bottom part of cap is flat to fit cut golf ball. top portion of cap is curved, only for cosmetic reasons I presume. What you see at top of cap is not a set screw. It is just a hole which exposes a small portion of tonearm. Tonearm is just a tiny bit smaller than 1/4 inch in diameter. I would have to remove the arm to get an exact measurement. Would rather not do that for set up reasons as I have arm dialed in for my cartridge.

Understood - no need to unmount anything! I see that top hole as where a screw inserts down into the ball half, then the arm tube is inserted. Of course, they could be joined with epoxy, which is what I might do. On an assembly line, screws and not epoxy make more sense... What's the deal with the small  horizontal tube for the fishing line in the ball cap? I've often wondered, does the line go all the way through? If so, how would it azimuth work if the fishing line isn't fixed to the ball? I have epoxied brass nuts in holes for use with brass screws to mount the fishing line in my 2 clone arms.

BTW, my plinth and base are drilled and bearing, spindle and platter installed and turning well. Pillar samples are drilled and ready to cut along with suspension arm for install. 3D printed cup should be here today. Suspension arm is 3" in length or a bit longer (t's silly, but why not be exact...)? Would love to send you a pic at some point.

In the past, I've used a 6mm od diameter carbon fiber rod (4mm id). 6mm us slightly smaller than 1/4". From what I see, a standard arrow shaft is 5/16" od, which would make it 7.9mm od. Any way you can confirm your arm's diameter? Also, how does the cartridge mount connect to the carbon fiber shaft from the bottom? It looks like it's carved out a bit and the shaft sits into it. Glued on or screwed on?

The small horizontal tube goes all the way thru the cap. Fish line is fed thru tube. It is then knotted and slipped back into the tube. The fish line is looped a couple of times around the aluminum machined collar that fits on the horizontal part of the gallows post. The twists I mentioned give the arm anti-skate compensation. The beauty part of this is when you rotate the machined collar back or forth by your fingers, you get a wide range of azimuth control in either direction. And you can do this on the fly to dial in perfectly. This is one of the most ingenious azimuth adjustors I have ever seen. I believe the end of the arm tube is flattened ever so slightly and the cartridge mount sets on it with one set screw. You can adjust zenith by loosening set screw and moving the cartridge mount either way. Mine came preset by factory and they say to leave it at the angle it is set at, although you can adjust it if you have to. I do not know what the factory angle of degrees it is set at. Would love to see the pics. Keep me posted.... Tim
