Ok,
I finally got around to my SSR4 cases. These are the ones from DF Countryman for $3.75 each. I uploaded a series of pics to show how I modified them to work. It really only took about 15 minutes for each enclosure. Very easy to do. Here are the steps I took to make them usable:
1. Pull the studs out with vice grips by twisting first them working them out.
2. I took an old 1" wood bit and ground the point off of it.
3. Chucked the wood bit in my drill press and ground the stud mounts down flush with the floor of the enclosure.
4. Laid the SSR4 board in the enclosure and marked the holes.
5. Drilled holes to be tapped for 8-32 screws.
6. Installed the nylon stand-offs.
7. Mounted the SSR4 with 8-32 nylon screws.
By the way, I have a bunch of the nylon stand-offs and screws if anyone would like to try this. I bought 50 of each from Amazon for I think just under $9. That comes out to .09 each.
Cheers,
Dave
