I am in the same boat. I've got all of the parts, kind of figuring out things looking at the pics from this member's gallery

(even though I noticed that the best pictures seem to have been taken down)

and going by the instructions from the how tos. I haven't tackled the fabrication just yet, but the 1-3/8 ID seems a little small at a first glance...

There's a few photos on OP's album so you can see what the finished item looks like. Or alternatively if you can find one, HOPE did a bolt on clamp to match up to their disc brake system. The clamp only fitted the carbon leg as the aluminium legs are a slightly smaller diameter and were never considered strong enough to take a disc brake.
