Framebuilders - Knockdown Connectors

I want to convert one of my old frames into a knockdown so I can pack it into a 26"x26"x10" airline acceptable case to take with me when I visit my dad in England.

S&S Machine will only sell their connectors to "Professional Framebuilders" so it looks as though I''ll have to make my own connectors. Has anyone here made their own?

I have some 2.25" dia. aluminum and I am thinking of a splice connector (with trimmed sides down from the 2.25") and 4 allen head 1/4" bolts top and bottom and then two fixed pins brazed in the frame tubes - one in each frame tube at the connection locating in holes in the aluminum splice pieces. The pins will handle twist and tension.

Any thoughts?

I saw a DIY takedown somewhere around- "folders" subforum, I think. The guy had started with a BMX frame and, after cutting it in pieces, just slip fit smaller tubes inside the frame tubes and held it all together with pipe clamps. Probably not particularly sturdy, but I guess it worked for him. Try a few searches in "Folders" and you`ll probably run into his thread.

someone that posts on BF copied the couplers that Rene Herse used. Pretty sure he posted it in "Framebuilders"

here is a post (http://www.bikeforums.net/showpost.php?p=9204522&postcount=111) with a picture of the frame. You should be able to track down other posts about it, or PM him

Thanks for that link - I Pm'd.

Looks like he used the seat tube for the top connector with an extra frame clamp screw - interesting.

it was a pretty clever system when Herse did it, and using the seatpost is a really good idea too. It might make it a little less sturdy, hard to know without trying it.
