Does Polulu have miniature couplings?

I have a project I’m building which needs to couple two small shafts of different sizes. One shaft is 1/8" and the other is 1/4". McMaster doesn’t have exactly what I’m looking for, so maybe someone can point me in the right direction. I’m trying to avoid the hacked look in this project, so hand-drilling is out of the question.

Does Polulu sell anything that might work?

I need to join two small shafts of different sizes. Outer diameter 1/4" and inner 1/8" to Outer diameter 1/2" and inner diameter 1/4".

Thanks in advance.


Unfortunately, we do not sell any hardware that would be suitable for what you want to do. If you are still looking for a solution, my best suggestion is to just try a Google search for something like ‘1/2" to 1/4" shaft coupler’, which seemed to bring up a few results that might be promising.
