Electro etching BK7

Just be careful of washing out the original etch with the higher voltage. Kinda like a pixel on a picture when you enlarge it.

I'm assuming maybe two 9v batteries would be good to go?

I'm gonna daisychain a few 9v cells together when I etch. I assume the more voltage, the faster the etch?

Be careful you don't go all the way through to the other side 1 good 9volt is all that's needed, it should take only 5 minutes or less per side

I'm gonna try this on my bk20 coming in. If I mess up, then it's all your fault!

I thought you would try it on MTM's 16 first you won't mess up I messed up by not haveing the positive to Ground and it did nothing so I stripped my 15, 4 , and 20 anyway after reading Granite thread I saw that mistake. Never had any trouble since. Here's a few more with just 1 9volt you can see my 15 and 4 that by not haveing the wires right didn't work the 17 and Potbelly just fine

Yeah, good idea!
