Hey guys,

I got some purpleheart for a project and have been working with it. I resawed some 8/4 in half and after about a week of sitting around, there seems to be something seeping out of the growth rings on the freshly sawn face of the board. Looks like some sort of resin or sap or something. This was kiln dried and feels dry to the touch, so I don’t think it is water. Anybody got any clues? I’m not too worried now, but I don’t want it to screw up my finish.

Purple Heart has lots of resins in it. If you resawed, check your bandsaw blade and I bet you find a lot of gummy resin on it. As far as the wood, just sand and finish as usual. It will seal it in and you should not have any issues.

Gummy resin is right. Purple heart is notorious for this. Beautiful wood but hard on tools! Finishing should not be a problem though. Use a UV resistant finish to slow down color changes. It tends to get brownish pretty quickly without it.

Thanks for the tips guys. I am quickly learning that this stuff works about as well as aluminum, except with splinters. Aluminum would be easier. Oh well, I love experimenting with new woods.

Yeah, Purpleheart is hard and tough. I just finished making 32 carving tool handles from the stuff and its slow going. Finishes nice though. Got another 32 carving chisel handles to do from the same stuff.
