Embarrassing admission....Happy Number 38 guitar to me.

Hi Ozzbike,
I have tried the same decal method using packing tape and laser printouts. The process works well. It takes me quite a few layers of tru-oil to cover the edges though. Hopefully the spray poly works well.

G'Day Trevor,

I am using aerosol can polyurethane. This one is a gloss finish. I hope it will cover the tape quicker than Tru Oil.

This stuff.....

Hmmmmm....the tape is very thick and is going to take some covering.

I think I will let it hang for a couple of days and then do some wet sanding and see if it loses its edge.

I am liking the body....it has 2 x 3 coats of poly on it now. I will let it hang until next week....and then wet sand to 600 and see what I have. I may have to buy another tin. I think I should have sealed the body with CA glue first as it is soaking up the poly like a sponge.

Trevor,

How did yours go? I have sprayed and sanded three times now and the edges of the tape are still easy to see.

The waterslide decals are way thinner and easier to hide. I may have to consider them for the next one.....again.

I had to go to the BIG Green shed today...and here on the sunny coast an Officeworks is right next door.

So after reading some stuff...watching a video or two...I have decided to give making my own conductive shielding paint a go. I got some graphite powder for about $5 from the tool shop of the big green shed, the water based acrylic paint was $10 from Officeworks and the paintbrush was $1-70....I did not need the containers but I thought why not....$3-00.

So lets see how conductive I can make it.

Keen to see how that works out

Setting up your own version of the Frankenwashie Lab in Buderim?

Oh does Frankie do the same stuff? Maybe I should read his threads....it may save me some time. Thanks.

Don't think so. It just sounded like an Egor type of experimental activity.
I have used conductive shielding paint a few times but bought pre made stuff on eBay.
Tend to think your idea should work.
Cheers Waz

This stuff is not easy to work with. WARNING...graphite is evil. It will get into...dust over...anything and everything.

Lay out some paper towel before you start.

The ratio was listed on one YouTube video was volumetric....imperial though....1 ounce of paint to 3 x teaspoons of graphite. So a google conversion from USA volumes to metric gave me roughly....30ml paint to 3 x 5ml (15) of graphite.

I have a measuring cup and that works well for the graphite.....then just tip it into the container. (Oh get a bigger one then mine.)

The paint measures fine as well. But how do you get it out....it is like honey....lots of end of spoon scraping.

Mixing was fun too.....dribbles of water and end of teaspoon stirring until no more gritty feelings.

I have a consistency of a thick shake will a little fine ground salt in it. One small strip on a double layer of paper towel.

The absorbent nature of the towel may be closer to unsealed wood than I thought. I will leave it for an hour and put another layer on.

I have dug out my multi-meter and will see firstly if we have continuity and then see if I can measure the resistance. Maybe somebody here would be able to advise if the end result resistance is any good as a shield to R.F.I.

Lunch Time now.

After one hour we have no continuity....and we have 2.9k ohm resistance. Maybe that is the resistance of paper towel?

Interesting number though.

Another coat of paint on the paper and leave for another hour and check continuity and resistance again.
