This might be stupid question, and probably is...

How to measure 38/40/42AGW wire thickness? I can't do it with typical ruler, do I :blackeye

I'm going to dissemble few popular inductor clones to check what construction do they have - type/style of wiring, wire diameter, and obvious things before I do that (coil diameter, inductance and resistance).

I'm going to build a simple coil winder and start rolling my own crap

Go for the digital ones, they measure in imperial and metric at the push of a button.

You could also buy a wire-gauge.... :thumbsup

I think this is probably what you're after, you may be able to order one of these online from America, I should get myself one too.... :thumbsup

They are good, but only for checking wire or plate gauges, I have one and never use it. It just acts as ballast to make my toolbox heavier..

A vernier calliper is good for measuring length, depth, diameter etc. Once you get one you wonder how you ever managed without.

For such thin wire thicknesses I would think that the caliper would be better than the wire gauge. Just my 2 cents.

Yes again!! Think screws (metric or imperial?), holes diameters and drill bits, PCBs, enclosures, components, whatever... :horsey:

In the last millenium old hams just wound n windings tightly on a round pencil and measured the width with a ruler. Then they divided the outcome by n. :idea:
