Hi, you provide the recommended size for the magnet wire needed for the project (34awg) but not the recording wire. I have some but I think it may be too small. Can you recommend a good size? Thank you!

Good question. This website:
http://www.videointerchange.com/wire_recorder1.htm has a lot of information about wire recorders, including a micrograph of it next to a human hair.
Recording wire is quite thin, about 38 gauge if my calculations are correct. It also has to be steel, not copper or other non-ferromagnetic material. That's why the experiment suggests getting wire made for this purpose on eBay. It doesn't seem to be that hard to find... e.g.:
