motorbike stand M10 strength ?
givemethebighammer - 25/5/08 at 05:34 PM

I made a motorbike stand like the one in the picture today (used a bit more of my metal scraps up). I used a piece of M10 studing as the pivot that threads through the swing arm pivot of the motorbike. It works fine only the M10 studding bent. The studing did come from B+Q so was possibly not high tensile though. The question is, will high tensile studing bend as well, if so what material 10mm thick won't (I had thought that a piece of high tensile rod with a M10 thread cut on the end of it might work). It can't be any more than 10mm as that's the inside diameter of the motorbike pivot.

thanks

I always find studding is very bendy...

Can you not use a decent M10 Bolt? Should be a bit stiffer!

I would expect 8.8 studding, if you can find it, should be fine. The stuff you get in hardware stores is really shi*e low grade. The 10mm rod with threads cut at the ends is the best solution though. Or see if you can get an 8.8 or 12.9 bolt of a suitable length.

Hi,

I made one of these stands for my Thunderace a few years back.

I used M16 studding, turned down on the end to fit the swing arm pivot.

(see pic)

As said you can get higher tensile studding. The cheap stuff is just a collection of fractures waiting to happen.
Steve,

cheers guys a few ideas there. I think the fastener place I use keeps high tensile studing. I'll try that first then think about other ways of doing it.

After a bit of a rethink, I redesigned it, the bike now pivots on two pieces of high tensile 10mm rod welded into some 19mm thick walled tube, which slide in and out of some rhs. I added some M8 bolts to lock everything off. Works very well (used it to degrease my chain this afternoon. ) Rescued attachment imag0299.jpg
