Post subject:  Smokin' ziricote

I was cutting small pieces of ziricote for "patio stones" to be inlaid in a rosette. The wood actually started to smoke from the fret saw blade (honest, I wasn't sawing that fast).

Then I was putting the jointed ziricote back through the thickness sander, and after about 7 or 8 passes, it started to smoke too! Checked the sanding belt, it looked fine.

So today, I'm finally leveling the rosette, again with the sander, and after about 10 passes, the ziricote was HOT.

In every case with the sander, I was taking very light passes, trying to avoid gumming up the belt.

Anyone else ever run across this?

Geez, I thought maybe I was missing something from back in my teen years, Steve! Is that why they call it Mexican crack wood? :D pizza :D
Sorry. Nothing intelligent to add, Steve.

While enjoying an icy scotch and soda last night, I wondered if you had flooded the ziricote with CA glue, and if the heat from the sanding could have caused the CA to smoke.
I often ponder the mysteries of the universe after a (second or third) beverage. Usually, to no avail! :D

Steve,

Haven't worked with ziricote a lot, only a couple of guitars and headstock veneers, but haven't had that problem.

Have had similar problems with Ipe. Predrilling is mandatory and the wood would smoke and occasionally boiling oil would appear while at the drill press. Went through dozens of counter sink bits that summer.
The bocote I currently have seems like it is doing what you you describe on the sander.
I think I will switch down to 60 grit.

Worst part about those smokes from dense hardwoods is that they seem to be poison. One breath of that stuff and I feel bad for days. Needless to say I try to use positive ventilation and/or slow down the tool enough to stop the smoke. The explanation I have heard is that trees make poison oils to stop bugs from eating the wood,

That is interesting Steve.

I don't have a clue but I will be starting a Zircote build soon. I'll pay close attention.

I had a similar experience with smoke and a gumming belt, but only in one particular piece of ziricote - another piece, cut from the same board, didn't give me any trouble

Brian, Ipe is very hard wood. It is used for the floors of semi trailers because of the abuse it can take.

Depends on the piece... some dense ziricote with a lot of black can burn and gum things up. With sanding go fast and take very little off each pass... it takes forever but that's the way it works sometimes. Also feeding into a drum sander at an angle so the same width of sandpaper doesn't have to do all the work can help an awful lot.

Sharp edge tools are your friends for these woods... ideally using abrasives should be reserved for only the final finishing steps but that's not always practical.
