Before I got going on Daves front triangle, I wanted to work on the seat rail clamps for Devins battery mount. Using some ss308 bar stock, I drilled a 7mm hole with them sandwiched together for the rail contact. I then drilled and tapped 4mm holes for the anchor screws. After cutting them into the individual clamps, I tried to use an end mill in my drill press to face them. The cheesy drill press and vise wasn't going to let that happen. I'll think about how to face them while I'm fitting up Daves frame.
