The quick tip series consists of short videos on a guitar or amplifier repair or maintenance topic. In this episode, I will make my own electrical shielding paint to use in guitar pickup/wiring cavities.
Small Quantities:
Graphite: amzn.to/3MmrQ7w
Craft Paint: amzn.to/3QcJonT
Larger Quantities (as shown):
Graphite: amzn.to/47acj2U
Craft Paint: amzn.to/3MidQM0
Tools:
Disposable Brushes: amzn.to/479aLpD

Important question... Do you have to connect the shielding paint to the ground circuit of the guitar? Iv never seen anybody doing this

@j.aleman2348 3 месяца назад

Btw I have a Les Paul with the typical cavities of pots, neck pickup, bridge pickup and the pickup switch (which are separated)

@hacksguitarhobby 3 месяца назад

It works best when you do. It's not absolutely required, but it won't do very much without it. In an LP, your switch and your pots will typically contact the paint and ground it that way. Pickup cavities might not get grounded unless you're intentional about it.

Try putting on a second coat after the first one is dry, like the next day. Professional EMF paints instructions usually recommend putting on two coats, which translates to my personal experience that with whatever I'm using as guitar shielding paint I do usually get a better conductivity reading with two layers than I'm able to achieve with even a thick single coat.

@hacksguitarhobby 10 дней назад

I definitely do that, and it does help conductivity.

@hoollehoop9299 Месяц назад

i've done this before and made the obvious mistake of mixing up the paint to a consistency that seemed to conduct really well when nice and wet, only to find that when completely dry (maybe a week later!) it had absolutely zero conductivity

@hacksguitarhobby Месяц назад

Interesting, probably needed more graphite.

I've been wanting to try this. Thank you for the video.

@hacksguitarhobby 11 месяцев назад

Any time!

@podoz 6 месяцев назад

thanks so much, i'm about to make my first batch. It would have been interesting for you to test the conductivity of the bare wood or non-conductive painted wood, to see the conductivity of the cavity with no conductive paint.

@hacksguitarhobby 6 месяцев назад

Oh, that's easy. There is none. Resistance is infinite, there is no continuity or conductivity... however you want to say it.

@jeremycusick5399 11 месяцев назад

I've used Slip-Plate graphite paint from the farm supply store with success. It's pretty cheap and pre-mixed!

@hacksguitarhobby 11 месяцев назад

Nice, I’ll look for that!

@MackDaddy8154 5 месяцев назад

Freak'n sweet! This helps a lot brother. Thanks for sharing.

@hacksguitarhobby 5 месяцев назад

Glad it helped!

@u563rick6 7 месяцев назад

What’s an acceptable measurement?

@hacksguitarhobby 7 месяцев назад

Good question. The only reference I really have is that standard Fender paint that measured around 25K Ohms with the leads about 2" apart. The closer to zero, the better, but I was not able to get it under 1K.

@letmepicyou 4 месяца назад

Everybody makes this junk with "graphite"...I have yet to figure out why nobody uses something that actually works, like powdered aluminum...

@hacksguitarhobby 4 месяца назад

Because graphite conducts and is more readily available. There is another fellow in the comments that used powdered copper. If you have used aluminum, please post the ratio of your mix to help others, and I may try it myself one day.

@letmepicyou 4 месяца назад

@@hacksguitarhobby So...why do my comments keep getting deleted?

@hacksguitarhobby 4 месяца назад

They aren't by me, and I don't see any comments being held for review. RU-vid is pretty picky about language, so they could be filtering.

@letmepicyou 4 месяца назад

@@hacksguitarhobby It's literally nothing more than a comment about how the molecular structure of graphite isn't suitable to block radiation (which it ISN'T if you know thing 1 about physics), how graphite isn't used anywhere in the WORLD to shield electronics, or reactors, or ANYTHING, so why would it be considered something acceptable to use, when for the exact same price (about $20 a pound) you can get powdered aluminum, aluminum being recognized pretty much universally as a shielding medium? I just don't get the physics. Both products are readily (and cheaply) available on Amazon. So why muck about with graphite? Just because something 'conducts' doesn't mean it 'shields' well.

@letmepicyou 4 месяца назад

@@hacksguitarhobby In fact...I'd put $5 on paint containing powdered aluminum being demonstrably better than graphite by an order of magnitude when it comes to RF shielding. Provable by any number of ways. And we haven't even gotten into putting fun stuff into paint, like lead oxide.
