The JagMaster

Thanks for those photos Jonathan. No trouble seeing them this time! And for showing the results. I have always wondered if the paint is anywhere near as good as foil, now I know.

 

Is continuity enough to prove it's as good as foil? (Assuming foil is 'good'). I'm not being sarcastic. I genuinely don't know!

I do love the look of copper foil, but the ease of slapping some paint in there is quite appealing, too.

 

I don't think continuity is enough to prove the paint as good as foil. I used resistance to check conductivity. After 6 coats of the stewmac shielding paint, I had conductivity, but still rather high resistance (70+ ohms).

Is the paint a conductor? Yes. Is it as good a conductor as copper? Nope.

But then there is the practical side of the question. At what point is the paint good enough? Are you getting no benefit with shielding paint until you get to 5 ohms resistance? Or is 100 ohms the threshold?

I used the paint 'cause I had it. Because of the uncertainty of whether or not its truly effective tho, is why I will use copper foil on the next build.

Edit: How many coats did you apply to get to 0.2??? I would say that is pretty equivalent to copper foil!

I've been away from this thread too long. Coming along very nicely! Love the gloss!

 

I've used some other shielding paint that had copper in it; it was brown instead of black. It was called Noise Hell (kind of a Japanese joke). I think it had considerably higher conductivity than the carbon-based stuff.

 

Nice catch on the buffing wheel Jonathan. The guitar is a stunner!!!

 

It sure is! Love the mock-up.

 

Rick....buahahahaha where the heck did you find that....ahahahaha "we drive on the left", man you are bad!
Buahahahhaaa.
I am crying!!!!

 

It's the black eye that sets it off

 

It is the whole picture, it seems like someone arrested the Queen after a fight and what it writes on the label she holds,at the photo taken at the police (maybe)station !!!!

 

Re the " conductive paint," unless you have zero ohms continuity, any areas with a few ohms resistance between a "true earth" and your painted cavities can, in extreme circumstances actually act as an antennae and introduce low frequency interference ( mains hum ) into the system rather than shield it. It could possibly even result in your guitar "picking up " 2-way radios and radio broadcasts...............if you are playing very close to a ham radio transmitter or broadcast tower. I used to have a Burns Orbit 3 amplifier when I was very young which used to pick up the police base to car transmissions from the "cop shop" across the street. One night we heard base telling a car to come and quiet us down.......the movie theatre around the corner were complaining!

Killer guitar by the way, superb work!!!!!

That's a beauty. You've certainly done yourself proud.

PMSent.

Out with the old in with the new (and better).

Sorry, Jonathan, for the derail. It was suggested that we get new avatars for the new Software.

I agree with da capptin-video, please.

 

Looks as stunning as
I expected it would, now to hear some audio clips!
