Next up I worked on the armored ball mount for the machine gun, which showed ugly gaps where there is supposed to be form fitting armored plating, and also the ball is mounted too far forward. Here's an earlier pic with the unmodified armored ball showing how thin the plastic is, although it's hard to see clearly in shadow.

I decided not to move the ball back as it was too complicated to fabricate a new mounting bracket that would fit exactly and still move freely. But the gaps could be fixed relatively simply with some epoxy putty.
First, I want to show off my new MG-34 with the correct Panzermantel, courtesy of rctank.de. I think the tooling is actually Aber (beautifully made and accurate), but with an LED and fiber optic installed which also works well when tested.

To get it to fit I used some silicon fuel tubing to space it back properly and make it a press fit so as to be removable for painting and maintenance. I also crimped some JST connectors to the wiring to be able to remove it instead of soldering. I should have done that with the Bosch headlight LED but didn't think of that at the time so that's already soldered in. If it fails I'll replace with the connectors.
Here's the putty after it was cured, after lots of sanding and smoothing with needle files to get things straight and smooth. I deliberately angled the inside edges to give the illusion of depth so it wouldn't look so shallow. The putty was form-fitted to the ball while still curing so fit would be perfect and movement unhindered. The putty is Tamiya epoxy putty, and water was used to keep the ball from sticking while forming the concavity.

Ignore the tape on the end of the MG. The tip is a press fit and is a bit loose so will need a more secure fixative, although I'm hesitant to glue it and may just use blu tack.
I forgot to take a clear pic of the stock mounting plate but you can see a part of it in this pic. It locks the ball down and works well, though does restrict some up/down movement because of the bulk of the LED mechanism butting up against it.
