Mark and Todd's Cotter Pin Press Project
Mark showed a few cute bike tools he and Todd Sorlie of Alpha Engineering came up with: The 1st is crank cotter pin driver/extractor. When Mark tred to buy the excellent Park Tool item, he found it had been discontinued a few years ago, so he built himself one.

Then he heard that other classic bike nuts were paying high prices on eBay for the Park and the funky, but cool, lever type press by VAR. He had Todd Sorlie CNC a batch to sell to the classic bike crowd.

Then Todd, who is into antique bikes, ran off a few wider ones to sell to the High Wheeler crowd. Some of the earlier bikes used larger, rectangular cotters.
