Re: Reproduction aluminum parts
Also, due to the light weight I could make replacements for all those fragile fiber gears. The weight wouldn't be terribly more and it would work more consistently. Thoughts?

Re: Reproduction aluminum parts
One big thing I'd like to do is a variety of horn cranes for cylinder machines. In my opinion, the ones currently available are too expensive, and I sure know a year ago I would have loved to be able to get a horn crane cheaply. I know that cygnet cranes are also in high demand, and I don't know if anyone reproduces those early cranes for the 14" horns. Also, reproducer shells! I know orthophonic and later Panatrope tonearms could use them, as well as a variety of lower end machines.

Re: Reproduction aluminum parts
How about a tonearm bracket for a VV 2-60?

The crook-tube at the end of Columbia cylinder Graphophone tone arms like the style BO(T), and reproducer assemblies for U-S cylinder phonographs. Should also mention that you can use filament that is designed for lost-wax casting, and cast (or have cast) the parts in real metal — brass, aluminum, etc.

Re: Reproduction aluminum parts
I know a guy who works with a firm that can 3D print metal. Like I may have said earlier, it's not quite that simple, but it will yield far better results than my rather amateurish attempts at casting. Casting aluminum is a LOT harder than you'd think, it's pretty hard to get it right and smooth.JohnM wrote: ↑Sat Jun 25, 2022 9:24 pm The crook-tube at the end of Columbia cylinder Graphophone tone arms like the style BO(T), and reproducer assemblies for U-S cylinder phonographs.

Would love to enjoy my 2-60 machine for once!gunnarthefeisty wrote: ↑Sun Jun 26, 2022 2:46 amThat's a great idea! As well as the 2-60 bracket that I don't believe is made.

Re: Reproduction aluminum parts
Well, they managed to cast them smooth in the old days! I actually have foundry experience, used to work at my brother-in-law’s foundry where we cast bronze and aluminum signage, mailboxes, tee markers, etc. I am a jeweler and metalsmith by trade and have done considerable lost wax casting. It’s a matter of casting technique and alloy whether you achieve a smooth surface or not. Aluminum alloys do shrink more than most other metals, so shrinkage rate would be factored into the CAD design, as well as alloy choice.gunnarthefeisty wrote: ↑Sun Jun 26, 2022 2:45 amI know a guy who works with a firm that can 3D print metal.

Re: Reproduction aluminum parts
I think they can account for that shrinkage, I'll ask when I ask about prices. I believe what they do is use filament with metal flakes, then cook it to solidify the metal and melt out the plastic. My father is looking at buying an electric forge, so I may also look at lost PLA casting. Whichever is more efficient and accurate is the one I'll go with.JohnM wrote: ↑Sun Jun 26, 2022 8:18 amWell, they managed to cast them smooth in the old days!
