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.

 X-mas present on its way: 24" BMX. 74.5 HA and 14" chainstay (13.75" slammed with small 2.0 tire)

 Blue vein Stout 24" fork
 I've been swapping parts around and decided to try the Ti frame out as a dirt jumper. I aimed for it to be a do-it-all frame but it has worked out surprisingly well as a single speed (despite the vertical dropouts). I used a pre-stretched chain and my normal gearing and its sitting tight. The longer 15.75" chainstay and lower BB height make it harder to manual on the street but I was on the back wheel through rollers at the trails with little effort. The lack of a HT gusset and the .89mm thick (thin) downtube have me a little cautious. I would have preferred to build with a 1mm or 1.2mm thick downtube but they weren't available when I built this frame. I have a new welding machine with a better pulse function that I intend to use for some Ti BMX race frames soon.

Hilltop Weekend at Bernies with special guest John Stamos

Had a good weekend on the Hilltop except for the part where Nathan's foot went the wrong way. He's the one doing threes, cans, bars, trucks and whips:

22 XL fork

A 22" fork with loafs of tire clearance for the 2.425" tires and a super strong, 24X1mm threaded, one piece machined steerer. Its heavier but much less likely to bend than the alternatives:
I stuck a steel tubing insert in Todd's new fork to prevent bending, though his old butted fork had an Aluminum insert and still bent that much. This steerer is about 3mm to start with, so it should last longer than the fork legs.
