    Has anyone tried that? I'm curious about it... but cannot screw up this frame.

    I'm intrigued with the idea, but have not tried it. I'd like to see some examples too, if anyone has used this process. I have used 2 x 4 s to straighten frames and forks, they work well and don't leave 'marks'. Using the broader surface area of a sturdy board like that doesn't put all the pressure on a concentrated spot like a pipe or bar would.

    Are you planning to paint the bike or use the existing finish, is it factory paint?

    When cutting up a frame, I managed to put a flat spot in one of the seat stays. I took a piece of pine, cut a notch (against the grain) to fit the tube, and used that to take out the flat spot by firmly tapping it with a hammer. It worked perfectly with no damage. But as always, no guarantees.

    I think this would work for you if you added two braces to fit snugly between the upper and lower tubes. Cut notches to fit both the upper and lower tubes, position them at the start and end point. You could even cut your notches a little larger and put rags between the block and frame for protection.

    Then using the first block with the notch to slowly work the tubes flat.

    I'd suggest trying it on a disposable frame. Squeezing those tubes down will tend to tilt the head tube forward and change the angle slightly. Could also cause the tubes to twist at the welds.

    No experience with this but it would make me nervous on something I didn't want to break/re-weld.

    I don't have a spare frame. It took me long enough to find this one. The crap thing is... I gave away one of these frames a couple years ago!

    You'll figure it out. I've seen your work and this will come out as fine as all the others.

    As a former plastic modeler I have worked with styrene sheet to build things. I bought it at hobby shops specializing in RC and plastic models.

    Shroud on the shifter idea...
    Rubber boot from the auto salvage yard. Various cars have a rectangle boot on the emergency brake handle between the seats. Would be easy to work with and conform to bends...

    My Subaru has a "leather" bag on the brake lever, you could just make one

    The "For Sale" signs you see in hardware stores are made of styrene, but it seems to be more flexible than the sheets from places like Evergreen. If you plan things right and don't mind some sanding and shaping, you can make almost anything out of sheet styrene. MEK works great for cementing styrene, just be safe with it.

    The body, fuel cell, wheels, tires and engine block on this are all made from sheet styrene.

    @Psychographic , that little sand car, dune buggy, whatever is so cool! I would be very interested in seeing you do this process in a step-by-step.

    I'm a huge Weird Ohs model fan, and this is very much along those lines!

    I sent you a message, I don't want to sidetrack this thread. I did want to show what can be done with sheet styrene.

    It doesn’t say “styrene”, but I got a couple sheets of 0.015 thick plastic in the model section of Hobby Lobby. I’m assuming Gorilla Glue brand super glue will hold that well enough.

    I’m going to work on that this weekend. I guess the biggest question I’m going to have is, once made and attached, if it will be ok to spray chrome on? I’ll have to ask the plastic chrome guy.

    Spray chrome as in paint, or the process they use to chrome plastic such as model parts?

    Model parts are usually coated with a fairly thick coat of clear lacquer before they are plated. The reason for this, the lacquer fills a lot of small voids and levels things. Any imperfections are greatly magnified by the chrome. You should be able to do body work on the part, then clear it before sending it out.

    Like model or car parts. A guy has the process to do it. He’s retired, but does a batch maybe once a year now.
