So I made a little progress. At first I was not sure how to proceed as the kit doesn’t have any instructions, but after looking through some build threads and pictures over on the RPF I have a pretty solid idea on how to proceed. First item of business was drilling and tapping holes where needed.

I then ran into a hiccup to drill the holes for the ejector pins and lower chasis panel near the rear wall. The corners are too tight to fit my drill. After giving it some thought my buddy was kind enough to lend me a drill bit extension and that easily addressed the holes in the tight corner.

Also drilled the holes in the handle, here you can see the ejection push pins in place but missing the springs.

I am brainstorming electronics, you can see I placed a panel mount DC barrel jack between the ejector pins, this may end up being the charge point with the chasis and cartridge “talking” to each other through the D sub connector. Last step for now was drilling holes in the sides and cartridge and a wash in soapy water and put outside to dry.

That’s it for now, more to follow soon.
