Got some 30g wire. Trying get 1.8ohm - 2.0ohm. What size drill bit and how many wraps do I do?
TIA.

30 gauge kanthal has a resistance of about 8.3 ohms / ft. So you're going to want a total of just under 3" of wire, including the leads between the coil and the posts.
In theory, you should get the following fractions of an ohm / turn on using these common drill-bit sizes:
1/16" -- 0.1666
5/64" -- 0.2025
3/32" -- 0.2383
But again, don't forget about the length of the leads between the coil and the posts, you need to add another 0.0274 ohms per mm of lead length.

Thanks, folks. I guess every chart is a little different. I'll try this out later today.
