Where to get 1.5″ metal shims and metal working tools?
So, I’m trying to make an electromagnet with a steel shim-like material as a core. Essentially, I want the core to look sort of like this:

with the wire wound around the middle, in the notches between the two ends.
However, I need the shim to be around 1.5" -2" wide, and I can’t find steel shim stock at that width. Are there any places online that could help me out? Also, what tools would I need to cut the notches in the shim stock? I have some metal files, but filing gets a little tedious, and I’d be willing to put out some money for some good metal/woodworking tools. Thanks

Mcmaster Carr, or grainger industrial supply are good sources for shims.
there are several ways to cut the steel depending on the thickness.
for a quick easy setup I would suggest a jig saw with a metal cutting blade (see your favorite hardware store) and about 1/8" thick steel.
If you want to go ccheaper you can use 20 Gage steel and some tin snips to cut it, but it’ll be allot more work.
use several of the shims layered, and separated with a thin coat of lacquer.
Hope this helps
