Ok, looks like I can upload photos directly so for the time being Photobucket, Picassa et al can pound sand.
Making billet aluminum triple clamps
There are a few missing steps here because I was too busy making a mess to take pictures. These are for a CB450 with the steering deraked to 25*, to keep the trail within tolerable range the offset was decreases approximately 5mm, though I'm pulling that out of my back pocket because again...I was too busy making them to pay attention once the initial calculations were done. Both plates are bolted together and all bores are started with an end mill plunge to allow for boring head clearance.
Clean out yer hole!
At this point the bores are cut to spec with one of two boring bars. These are going to house some custom built 37mm Showa cartridge forks and a Honda spec heavy wall stem. Note, the bottom clamp has some extra cutting to accommodate the larger diameter of the stem at the bottom.
Here I've roughed in one cut on a ragged old bandsaw, then back to the mill to cut it to spec and a final pass with a flycutter.
Just for my Brutha Fruma Nutha Mutha Troy, here's a little Seasick Steve: Doghouse Boogie
