I got one of these kickstands

https://www.amazon.com/Ventura-Standa...1832435&sr=8-4

Problem is the point of contact with the frame on the kickstand is completely flat, whereas the frame has a little bit curvature. Hopefully, my illustration gets the point across. I would like to cut off the part on the kickstand that is in the way, or at least bend it.

Suggestions on how to do that?

so what metal working experience do you have?

screwed up the title; should be bending not mending...

experience? I know how to drill through metal, but never hand any experience with cutting/bending it. I've tried to bend it by sticking the unwanted end into the crack of a sidewalk and crank the joystick, but I'm afraid that hasn't produced the desired results.

Many kickstands are cast aluminum Pletcher, Greenfield..
cast won't bend well at all, tends to crack.

slight angle change at the mounting bolt squeezing the chainstays by the BB
may be all you have..

What is the kickstand frame part made of, stamped sheetmetal or is it cast metal? Is it thin enough to be bent to the curve of your frame chainstay?

It's a pressed steel plate kickstand, which you might be able to form by putting in a vice and bending with an adjustable wrench, or hammering into shape. Problem is that many of these are heat-treated and pretty resistant to bending.

Consider making an adapter for between the plate and the frame. It could be as simple as a rubber or wood pad, or you might file a piece of aluminum scrap for a perfect mating surface on both sides (kickstand and frame).

BTW- you might not have to do anything, flat kickstands have been bolted to curved chainstays for about a century, so it isn't a new concept. Just be careful not to over-tighten and crush the tubing.

this kickstand was badly designed. It does have a part where the kickstand adjusts to the frame, but that section is way off.

I thought about filling in the space with washers, but I'm afraid the axle would be just too crowded.



btw. the material is obviously steel

Any photographs of the situation would be much appreciated, there seems to be some confusion as to what type of kickstand you have, that is, the type that mounts between the chainstays, or the type that bolts to the axle and the chainstay around the left dropout. Also, I am not entirely clear on what the actual issue beyond the simple statement that the kickstand doesn't fit. Finally, do you have access to tools like an adjustable wrench, vise grips, channellock pliers, slip-joint pliers, a vise, or a ball peen hammer? A variety of tools of this sort would be helpful for you to achieve your goal, at least as far as I can assess. Good Luck!

And it matters what kind of specialized forms, say made of hardwood , you are willing to make .

some metal shaping goes so much easier with a few jigs and tooling creations,

to bang the shape into it.

will a kickstand matter that much a separate question.

Use a metal file.
