Not that I didn't believe anyone here, but....

I talked to my son, a journeyman/forman induetrial electrician, and he fully agrees to go DC.

OK. Anyone want to but a variac?

But, I'm asking for help. Would someone skim Amazon/ebay for a 6/12v power supply that would work? I don't want to start throwing good money after bad and i am clueless on what to get. I want to build that wood rig, not one of those foam cutter hand-helds.

1. $'s is a consideration.
2. As everyone is saying, safety is an issue also.

I just don't have any idea what to get.

doesnty matter how its built hand held or a rig like the video you showed. for a 2" bit of nichrome wire to burn a fret line on a neck all you need is a 9V battery. all very safe except for the wire itself that gets very hot. use an old car battery if you want. DC is safer than AC. 

What about the DC amps?

Would something like this work? (obviously with the output terminated differently)

Don't you have any AC to DC adapters (wall warts) laying around to try?  I sure do.  I think this should work.  You could plug into a cheap switched power strip.

seems like a lot of work to replace a Square & a Woodburner, just saying?

Yep I agree Brian Q. At least with a wood burner you can change the tips and do fret position markers too.


Brian and Taff...

I tried a soldering iron with a needle and chisel tip and while it works, I was not happy with the time or result. There's just something about that hot wire making a perfect line that resonates with me...

BTW I just looked closer and the resistance on the wire I bought is 1.31 ohms/ft.

I’m using a real wood burner, not a soldering iron, anything takes a little practice, even with the right tool? 

What's the difference?

I thought the gizmo in the vid was pretty cool and well thought out.  Some folks just like making things  :)  

That'd be me...

To be honest, it's something I discovered about myself not long ago. Never knew before that I could do it...

Is there some reason you didn't wan to use an automotive battery charger like in the video?

Mainly because of pushback from here...
