Wire thickness?

I might be able to get wire for engine detailing for cheap or free, but how thick is it. For example detail master ignition wire, for 1/24 scale models, how thick is the wire? Also, doorbell wire is extremelly thin as well, and very cheap, would that be the appropriate thickness for anything in 1/24?

Here's a good way of finding out-

dial calipers! (http://www.automotiveforums.com/vbulletin/showthread.php?t=484569)

Go on towerhobbies.com, they list the thickness of the Detail Master wire on there alongside calling it by what Detail Master market it as.

Also consider what MPWR is refering to.

This is some stuff that I've saved on my HD from time to time.
Maybe it wil help you.

Our Standard Ignition Wire is .012" dia, the CORRECT size for 7 or 8 mm standard ignition wire!

Our Race Car and Custom Ignition Wire is .016" dia., and represents Accel or Moroso hi performance wire.

Detail Wire is a very fine .0075" diameter. Use it for general electrical wiring on alternators, relays, etc. Also works well for 1/43 scale ignition wire, and as upholstery piping on seats!

Our Battery cable works great with our Battery Hardware Kit (DM 2430). It's .019" diameter
