Just did these today. It's a SPT, a stem/handle bar stub that clamps to the post to allow a handle bar bag to be mounted behind and below the seat. First (to my knowledge) done by Eclipse back in the 1970s. Also part of the job is a support strut set to span between the rear eyelets and the bag's rack. Normally these bags have a lot of bounce being canti levered off the bar/stem. With the struts the back end (or ft end if over the ft wheel) will have a vertical support brace. The SPT needs finish filing, cutting down the post clamp, cutting the binder slot and reaming for the 31.6 post. The struts are only begun. Andy.
Nice fixturing solutions and brazing Andrew.


I had to get myself out of trouble early this week. I have been building some bikes with integrated bearing head tubes and finishing them is some kind of nightmare. Although the cutters fit on park handles and work to dress head tubes on steel bikes, aluminum is a whole different animal. I got crazy chatter.

The only thing I could come up with was an internal expanding arbor. Thankfully it worked. the "RAW WAR" bike started it's trip to Australia.

The next thing was sanitary welding for local maple syrup producer. They tap 5,000 trees and produce 20,000 gallons of finished syrup. They have a good bush and get around $85.00/gallon.
