Pestvic Posted June 29, 2012 Report Share Posted June 29, 2012 I was reading HuntinDoug's thread about sand shading and I thought, Since he is using heat and what not to create a burst. Is it possible or feasible to do this with a heat gun? I wanted to get this brown dark burst maybe with trans tints... but thought it would just be a lot easier to heat gun it and sand back some of the over burned spots? idk, just a thought, or hoping some of you have tried/ done this and would post some pics. here is what im after Quote Link to comment Share on other sites More sharing options...
orgmorg Posted June 29, 2012 Report Share Posted June 29, 2012 Haven't tried it with a heat gun, but this is one I did with a propane torch. As you can see, it is not so easy to control how evenly the wood chars. A heat gun may be more controllable, but any time you get the wood hot enough to char, you are drying it out rapidly, and you will get cracks in the end grain. I happen to like this look for a lot of the stuff I do, but it may not be appropriate for your needs. Quote Link to comment Share on other sites More sharing options...
DarkAvenger Posted June 29, 2012 Report Share Posted June 29, 2012 I'd expect a heat gun to be much more controlled. I've never done it on a guitar but I've never gotten cracks on before. Always test it before, that should get your answer. Quote Link to comment Share on other sites More sharing options...
dpm99 Posted June 29, 2012 Report Share Posted June 29, 2012 Dang Orgmorg. That's awesome. Quote Link to comment Share on other sites More sharing options...
Pestvic Posted June 30, 2012 Author Report Share Posted June 30, 2012 Dark I was planning on testing on scrap tonight Orgmorg, do you think that If I added sand to the spots I wanted to burst? Maybe even add water to the spots that I want to char? I was thinking maybe if I add enough water it will get hot enough to char before it has time to dry and crack? Just a theory/thought. Anyway thanks for the pic, it definitely gives me an idea of where I want to go and what sorts of results ill get. What type of wood was that org? I was going to burst a maple top, maybe the tightness of the maple will give me less worries when it comes to cracking? Quote Link to comment Share on other sites More sharing options...
DarkAvenger Posted June 30, 2012 Report Share Posted June 30, 2012 I'm not sure, but water sounds like a bad idea. When water heats up, it expands... and it only gets to 100C/212F. A big factor is probably the type of wood your going to be using. I've done it on walnut and maple with no issues. Quote Link to comment Share on other sites More sharing options...
Pestvic Posted June 30, 2012 Author Report Share Posted June 30, 2012 whoa ok yeah nevermind on the water. haha Sweet man thanks on the good info that maple should have no issues cant wait to try now Quote Link to comment Share on other sites More sharing options...
orgmorg Posted July 2, 2012 Report Share Posted July 2, 2012 What type of wood was that org? I was going to burst a maple top, maybe the tightness of the maple will give me less worries when it comes to cracking? It is yellow poplar. I would expect a denser wood to crack even more. A big factor is probably the type of wood your going to be using. I've done it on walnut and maple with no issues. Were you doing it on the end grain? That is where it will crack, and I would be surprised if it didn't. Moisture exits the wood most easily through the ends, causing that last inch or so to shrink while the rest of the wood stays the same dimension.

Pestvic Posted July 2, 2012 Author Report Share Posted July 2, 2012 (edited) well here is some pics tested on scrap. The burst line is a little harsh so I need to burst a little more and then sand blend it in to the burst. but I have a good feeling it will turn out good Oh and here is a side shot. Notice it only affects the top of the wood and not the sides. Which is AWESOME. Also, when I put the burn color on then restain. I think the stain will add the moisture back.

Pestvic Posted July 2, 2012 Author Report Share Posted July 2, 2012 so far so GREAT!!! Quote Link to comment Share on other sites More sharing options...
Pestvic Posted July 2, 2012 Author Report Share Posted July 2, 2012 looking good I still need to even out some spots. I noticed it affected the glue. so next time I will have to work a little closer and faster and let the wood burn fast so the glue doesnt heat up. I fixed it with clamps but I learned a good lesson Quote Link to comment Share on other sites More sharing options...

Pestvic Posted July 2, 2012 Author Report Share Posted July 2, 2012 Thanks I think the hardest part is going to get the burst to be even Quote Link to comment Share on other sites More sharing options...
