I am changing the spark plugs in my car and find myself without my spark plug gauge. The gap is supposed to be .045" or 1.14 mm.Is there any way I can simulate this gap (thickness) of .05" by using standard items in my garage, like nails, wires, drills bits, etc?Thanks for any help. Would save me a long trip to the nearest supply house. This may be OT, but people in the group are familiar with tools and materials.

A lose fit on a sawzall blade (~0.035) might get ya by but don't think I'd do it.18 gauge wire is 0.040 something16 gauge wire is 0.050 somethingcopper wire will deform...maybe somebody else will get closer

Wouldn't even be close, card stock is like .5 mm or something. Like I suggested back when, use a CD, they're .047" thick.

I just grabbed a plug and eyeballed an 045 gap. Ended up close to 050 but that's still within tolerances.

Very very close to 3/64 which is .0469 (rounded off). If you absolutely can't go get a plug gap gauge use a 3/64 drill bit. Assuming you have one that is.

inside? outside? clearances for measurement device? down in a hole? Accuracy? If you know the dimension, why do you need to measure it? ;-)
