Blunt did it properly with the thickness of tube, your idea would be extremely weak, sorry
Well a way to make it stronger is jam another tube/weld some more metal onto the inside. Jamming a small tube in there to a snug fit seems the easiest though.
That still wouldn't work, the shim needs to be just like the Blunt shim. It would have to go down below the top headset cap, and the forktube would have to go down below there too. If not, the shim wouldn't hold anything in place, because it's smaller than the crown race and top cap.DONG! You've got it, just get a snugly fitting piece of metal tube, and a starnut to match then you've got yourself a mini HIC!
Way to be innovative dude, thats what the community needs!![]()
