Kishmar's 400 ATC fork


I spent some time making an insert that fits snug in this one. My one piece steerers are 3mm thick where this one is 2mm (plus the 1.2mm thick insert). This may sound overkill, but this is a fork that can fit a 26" wheel, so it needs to be tougher than a 20" BMX steerer. A mistake that I have seen on other's fork designs is to use a thin steerer with a short insert that ends about halfway in the steerer. The problem with this is that the actual bending force occurs over the entire midsection of the steerer, not just that lower 1/4 section. Case in point, a 1.5mm thick steerer plus a 3" insert:

Still haven't made the coating rig for doing more than three bars at a time. I'm worried that it might literally take all day to coat 20 bars.

Skipped work Monday to get super seasick on my grandfather's boat. I just about had a heat stroke and got pretty burnt despite sitting under the shade. At least we came out with the limit for our group in only about seven hours on the gulf. I brought up two of the snapper and the king mackerel.
A Kingfish before and after: 
 After work repair and sundown rides over at Hilltop. All of that rain did a number on the lines but its looking sunny for a while.
I still use acid to clean most frames of subtle surface rust. It also reveals any missed welds that can be camouflaged in the oxidation of the heat affected zone.
