I cut the blocks from a 6″ piece of 3/4″ square bar, I then milled off the bandsaw’d area to make them a little square-er and prettier, that wasn’t even really necessary though. After that it was just clamping, drilling and tapping to finish them up.

Next I started making the bands. I only needed 5ft of the banding, but the least I could buy was 25 so I had plenty to spare. The bands cut nicely with sheet metal sheers. I made the holes with a sheet metal punch.

The hard part about the bands turned out be getting them to just the right length. I’m glad I had extra.

These are 2 of my rejects. The top one is too short, and the bottom one is too long, it has to be pretty precise. I made the rest of the bands about half way between these 2 and they fit nicely.

Here’s one of the bands assembled. If you look carefully, this is actually one of the too-short ones. See how it doesn't quite pull flat to the block?

Here’s one of the finished ones after I got the band length dialled in.

I threw the u channel in the mill real quick and milled out some space for the bands.

Time to check the fit. Looks good. I proceeded to tighten the whole thing down.
