Made up this custom disc-brake retrofit to a co-motion tandem using a therapy brake adaptor. Had to machine a custom hub spacer, then machine the seatstay clamp for the torqu arm. The mount had to be modified as well and the chainstay needed to be coersed a little to clear the big 203mm rotor! seems to work well though.

Well, finally been getting back in the shop a little bit.
Did a coupler retrofit on a Voodoo as well. All set for paint, just need to make a little time for that. These are really nice frames for the money, I recommend 'em if you're looking for a budget steel 29'er.
And finally, mitered up and tacked the tandem frame. This one was a lot of tricky mitering as all the tubes except the seat tubes are shaped! The rear BB has two ovalized tubes meeting and intersecting a round tube and the BB shell. Lots of work, but I think it'll be a really cool frame in the end. A bit of a departure from my usual direct lateral tandems, but I wanted extra standover on this one. This will be all fillet brazed as well, due to all the non-round tubes.
