And then, Eureka! I saw that the diaphragm and needle part of the arm come right off easily, revealing a simple way to get the iPhone sound in. After about an hour, I had this baby working.
Step 1: Materials and Tools
-Some PEX plumbing scrap; one piece 4.5” long and another 6” long.
-Some dowel that was just a bit too big to fit in the end of the PEX
-A bit of electrical tape
Total cost: $0
I used the tools I had, including a drill press (but I’m sure you could do it with a hand drill), a 3/8” drill bit and some smaller ones, a utility knife, and a handsaw. Thats it.
Step 2: Made a Plan
Here’s the basic design in two parts:
The lower part is to redirect the sound from the iPhone speaker (on the bottom) down through Victrola. It has a slot cut in along it for the iPhone to fit in and a hole that will line up with the Victrola sound path. The ends of this part are plugged up with dowel to send the sound down through the hole and not out the ends. Check out the diagram for some dimensions.
The upper part is just to support the iPhone so it doesn’t swivel down to the turn table. So it just needs a slot cut along one side of it for the top of the iPhone to fit in.
Step 3: Got It Together.
Second I scribed a line from one hole to the other for the slot sides with my knife. To get as straight a cut as possible, I used the molding on a door frame to mark it (see the picture). The slots were done after carefully cutting successively deeper cuts on the scribed lines. To finish, I just carved the ends of the slots square.
Thirdly, I whittled down the ends of the dowels slightly, just until they fit inside the ends of the lower part. I then cut them to about 1/4” long and stuck them in either end of that lower part.
Fourth, I carved out access to the home button after marking it with the iPhone in place. Upon testing the fit in the Victrola, I found a bit of play so I wrapped a bit of electrical tape around the end to en-snuggen it.
