Ready for some stays.

This worked well. The pins are tight but can be removed easily with a pair of dike cutters. The bullets are a bit floppy but don't wiggle at all when the stays are installed.

It then used a transfer punch to mark the dropout and drilled it out as well. I initially tried using an undersize drill so that the spoke would have a press fit. My plan was to grind a taper on the pin so I could get it started. This didn't work so well. I discovered that the pins don't need to be tight to work in this application. Instead, I made the holes oversized and bent the pins slightly before tapping them in.

In order to keep the SS plugs on the dropouts while I was fitting/brazing the stays, I decided to pin them. This is a common technique for those building using tradition methods and lugs. The standard "pin" is a soft nail. Some builders even use square nails because of their natural taper.

I've never tried using pins myself so this was new territory for me. I chose to use an old 14ga stainless spoke as the pin since this area will not be painted. I first drilled an .080 dia hole in the bullet. Location really didn't matter.

Great work! The bullets and your tooling is super cool. I'm jealous of all those blocks of AL on the shelves!
