After completing my hi-hat stand
successfully, I needed a stand for my crash cymbal. We happen to have accumulated a lot of mic stands (and, ironically, no mics), so I thought the easiest thing to do would be to repurpose one of those as a cymbal stand.
I spent less than $4 on hardware for this. I already had the mic stand and threaded rod, and the rest I bought from the local hardware store. The build was very simple and took me less than 5 minutes to put together.
