While planning to make the brass mounting ring for the sp36 driver I found a flaw in the design. The battery tube only makes contact with the tabs used to secure the original driver. Two small contact points. If the surface of the driver retaining screws protrude beyond the brass they introduce additional resistance and decrease output. If the screws are slightly recessed there would be four very small areas where the tube makes contact with the brass circuit trace. A contact/retaining ring as planned to mount the sp36 driver would likely be beneficial for original drivers as well by increasing contact area and facilitating a slight recess for the driver screw heads. Sheet brass arrives tomorrow.
Copper disc to fill original mcpcb pocket in place and secured with a minimal layer of arctic ceramic epoxy. Just needs more fine sanding to remove a little more anodizing and a bit of polishing.
Sofirn SP36 Anduril driver reduced to fit and sitting in place.
Negative contact/retaining ring and positive contact disc from 18 ga brass sheet ready to solder to driver.
Driver screws installed with the tops just below the surface. It was a challenge getting the holes in just the right spots. Original screws installed but longer screws ordered.
