bobbing a rear fender
« on: November 27, 2006, 11:30:34 PM »
Is there a trick to bobbing one's rear fender? Or would I be better off locating a shop that specializes in this sort of thing? Someone told me I could mask off where I wanted  the metal cut and go at it slowly with a jog saw. Tha problem I see is that I wouldn't be able to curve the lip under and I'll be stuck with a sharp edge.

This is for my '73 CB500K2 rebuild. I will also be looking to swap out the stock tail light/break light assembly and replacing it with a smaller hipper looking set up. Any suggestions for that?

Thanks!

As for cutting, mask off where you want to cut, and then use a die grinder with a cutting wheel and bobb as you please. As for tucking the lip back under, I'm kinda clueless.

You can do what Carpy did to one of his builds, just take a section out and weld back together. That way you keep the curved lip.

Cheers

I just removed the fender and cut six inches off of it. Then I drilled new mounting holes and reinstalled it. I am using aftermarket signals so the fender rests on the threads of them behind the frame. Probably not rhe correct way but it took about ten minutes and works fine.

I simply sawzalled mine. Took a die cutter to make it perfect, filed the edge off, a little sanding, Viola!


It doesn't have the rounded edge, but it doesn't look like it was rough cut either.


Took all of 15 minutes.

Did the front fender the same way.


Just one bit of advice, do not use a table grinder to smooth the edge. It will catch and tweek the steel.

I like to use a 4 1/2 angle grinder with a cutting wheel, but a hacksaw or any other thing will work.

You can just cut the fender in half (or wherever you want) and remount it in a different position.

       Hey Ratfink,

                  Looks like a proper job to me. The taillight is a nice touch too. 8)

Very nice. If mine ends up looking as good as yours does, I will be pleased.
