Default quick ratcheting bar clamp

Today I discovered that a "quick ratcheting bar
clamp" (with soft jaws, mine is from Wolfcraft)
can be used to straighten fenders that are
flattened to some extent and show bulges on
each side. The QRBC can also be used in the
same way to straighten chainguards. It is
actually much, much better than ball hammers,
pliers, muscling with your hands, etc., to
achieve the same purpose. Especially with
fenders it is almost like magic as the damaged
part seems to "get along" with the method and
naturally follow its lead back to the original
position...

a ball pein and dolly works fine for me but an English Wheel
is the right tool for that.

Yeah, I better get an English Wheel to get down
with this problem I'll put it on the list
right next to the durometer, air drill, and
hypno-hygrometer!

But isn't that (the English Wheel) what they
use to manufacture fenders, and not to fix
a local damage with the fender still on
the bike?

Anyway the clamp works great! The ball hammer
is indispensible as well, of course, and not
just for this task.

But what is a dolly in this context?

OK, so the dollies are the pieces of metal to
form the fender/chainguard/whatever. Then yes,
I have dollies! Only not as fancy and not as
versatile as in that kit.

Amazing tho that the traditional ball peen
hammers aren't included, but perhaps they
assume people already have them?

The hammers look cool but two are identical
flats what I can see, and both are too pointy
for my purposes at their other ends, and the
all-blue looks wierd - what is it that you do,
with it?

The pick ends just have a smaller striking surface, the flat
ends larger.
Inside a mudguard, a ball pein has a good curvature for
typical dents. Flip bike upside down and use a dolly on the
outside. As with all panel beating, work gradually and don't
overdo it or you'll stretch the metal.

I have found that those clamps work well as a third hand when adjusting
brakes. Purpose made bicycle third hands seem to be antiques, but the
clamps work at least as well anyway.
