In frame making i think only dropouts and tapered headtubes makes sense. Notch the tubes and TIG weld'em.
Do u have any frame jig? and
Do u do ur own front suspension or do u buy'em.

6061 is a bit hard to get here, so i'm using 6082 for the frame, with a few small components using 6063. for the stem i'm planning to use either 2014, 2024 or 7075. for the sprockets i MIGHT laser cut it and later machine out the lateral tapers on a CNC lathe. lets see. but my first priority would be completing the frame. and about using 4130 for the machined parts is out of the question !! ha ha, i dont want my frame to weigh the same as a battleship !! lol
and yes, i wont be MIGging it, its gonna be TIG all the way, with T6 heat treatment after welding. my frame design allows me to notch the tubes while CNCing the box sections.
i'm half the way through building the frame jig.
i had built a dual crown 10" travel suspension fork in 2001. using 6000 series aluminum. no damping whatsoever !! you can say it was a glorified pogo stick lol !
