DIY bicycle badge. New Krupis (toads) is ready to go on a trip !

Frame brazing I use oxy-propane kit and flux coated brazing rods flux residue remaining on the joint must be removed Filed joint

New useful DIY tool. Dummy wheel useful to find location to brake bridge, chainstay bridge and check rear triangle geometry.

Nice work! Kinetic sculpture

Thanks guys! I use 700c -28mm tire, don't need to crimp the chainstays. It may be difficult to keep geometry straight by crimping chainstays, but maybe I'm wrong, I have never done it. Below first ''a la 1930'' design frame.

Some shaping tools: down tube arch manual ring roller with oak rolls and seat stay/top tube mold. Down tube ''thorn'' welded and filed Seat tube mitering Frame jig Patient process, tube mitering Closer to shape Drilling ventilation for inner rust prevention Handmade dropouts...

Thanks guys!
