Re: [CAD_CAM_EDM_DRO] Re: How to burn flat images in wood?

Yes, first clear coat the wood to be engraved, then engrave the image with a small tip bit. Now you can lightly stain the wood, so most the engraved lines receive the stain, be sure to wipe of the wood after staining. Depending on how open grain you wood is, you can either sand the remainding stain off or give the finish piece another clear coat......

Do it all the time....works for me.

A few months back, there was talk of Browns Gas torches. these use
water as the fuel soruce, and seperate the hydrogen and oxygen, then
burn them back together to get some high thousands of degrees, like
8k or some such.

the flame tip is only about 1mm so you should be able to scortch
pretty much any material you want.

Check the archives for links.

a note here is that many people try to compare a browns gas flame to
some other torch propane,acetelene or some such. it has too high of
a heat for normal steel welding and too small a tip for thick stuff,
so a simple comparison is terrible, but then plasma cutters and
oxygen cutters are so different they do not get compared often.

Also, there are claims of some odd self perpetuation machine using
browns gas. since you are not (hopefully) looking for a perpetual
motion machine, pass on those too.

But if you find any links to Buckaroo Bonzi, I'm looking for 'THE'
formula.
