The channels were easy enough as I set up my NWSL Chopper to do that (I really would like a way to add a micrometer adjustment to the stop. That would be SO helpful). I glued the smaller tubing inside the larger, let that set up and then used my Proxxon mini-mill to cut the notch in the end. That required making the tubing quite a bit longer so I could hold it in the vice .. call it ‘Sacrifice Styrene’. The .156″ sq. bits .. the large ‘plate’ are a pain as trying to hold that and file a slight taper on the back top and bottom edges (the inner faces of the top and bottom of the channel have a slight taper). Funny – I’ve been quietly griping about my Proxxon mini-mill being TOO mini. Then I come to things like this .. and it’s TOO BIG!! 🙂
Currently .. I am slowly filing the plates as needed to fit the channel profile and cementing them in place. I’m using the depth rod on my dial-calipers to set this precisely.
