The Desk Toy design project was delivered from our catalystservice.org order. We used McMaster Caar ordered reamers to get a good fit on the pins.
For a 0.250 pin, to get a sliding, we reamed it to 0.253, but that was still a bit tight. For press fit, we reamed to 0.250. The spring was hand made from a piece of spring wire.
All in all, a successful build!
