26 to 31.8 handmade stem shims

Hi everyone! Does anyone have considered to make an homemade version for 26 to 31.8 shims?
I've a 26 handlebar and a 31.8 stem and I don't want spend money for two pieces of metal.

Anyone have tried a solution?

Thanks!

If you can find a piece of 1.25" tubing with a .095" wall thickness, you could cut it in half and use it as a shim. Otherwise you will probably have to buy a new stem, bar or an actual shim.

You just need a piece of soft aluminum, 1/2 the thickness of the handlebar size difference - cut a couple pieces out of it, a little smaller than 1/2 the circumference of the smaller bar, and bend them to fit.

Your going to get close with the above ideas as the aluminum stock you will find will be right around 1/4" which is a little thick. For $8 you can get a product made for this on ebay but will likely have to wait for China shipping. Got one for my Dad's cruiser and it is solid.

Hello there, how much do the two pieces of metal cost?

No, the shim thickness will have to be 2.9 mm ((31.8-26)/2) or just under 1/8". The shim has to be the difference in radius, not the difference in diameter.

After looking up the aluminum you'd need for this, I realized it's just cheaper to buy the shims :

I did a shim from about 24mm to 26mm on my Funny Bike.

I think I used a piece of old irrigation pipe that I found at the local metal recycler, cut to length, and cut in half. But, as mentioned above, my thickness was thinner than what you would need.

I decided to use Interrupter brakes for my app, so I cut the shim material long enough for the stem + brakes.

If you want to go cheap, Problem Solvers shims cost slightly less. If your local LBS has a QBP account, they cost the same...about $10.
