Billy's 24" MTB race and trails
 Knarly. This horizontal knurling seems to make more sense than the typical diamond knurling for handle bars. Four piece in the works.

Pretty sure this took more than twice the time to weld than the typical front triangle (Due to the acute angles and the added surface area) It was a challenge, and sort of fun, but I don't think I want to make another any time soon.

 The neighbor's Alliance custom bike has Hope "V-twin" road disc brakes. The rear connector bled out so I had to do a re-fill job. I don't know why this system exists, as it seems to have way more friction than a well lubed mechanical brake. The V-twin is basically a cable that comes off the lever and pulls a plunger past the reservoir, so it still has some cable friction. I'd suggest a good mechanical brake.
 Stoked on gun metal color (trans pewter) and larger chainstays.

 These "T" handles are supposedly going to get caps made for handle storage. Just a thought on what they might look like:

One with removable mounts, externally butted seat tube, and straight gauge DT. The top one has a seat clamp, internally butted ST, double butted main tubes and is LHD.
I made the handles from the same sticks that these fork legs were made with: .058"/1.25" dia 4130. They're definitely a little heavier but can be swung at full force. The heads were modified by the CTY guys. The (multi-purpose) shape seems to make digging packed dirt easier than a spade shovel and still works well as a transfer shovel.

420mm ATC fork

The end caps on this one are 6.3mm thick and milled out in the center. This makes the outer edges much tougher and can be ground/grinded without distorting.  
This brace might get welded in place... (depends on where it goes). This makes sense for a suspension corrected fork as its a torsionally stiffer structure. In the BMX+ application it makes footjams possible and probably safer on one's toes than any other fork.
