Back in the early years this Nail, by Dennis Dwyer, was the second machine I acquired.  Third if you count the homemade contraption.  Its been torn apart multiple times, to the point where I think the frame is the only original component.  Over time its ended up with Dringenberg coils, a Leeverloc off some Spaulding rig, a front post I think Phil Holt made, other scrap hardware, chrome sanded off, etc.  Most recently I welded a roll cage to it and soaked it in motor oil for a spell.  Its interesting how your tools age.
