A bevy of bowls

[holmqer]

A bunch of mostly Sweet Gum Bowls with one Eastern Red Cedar. They are all treated with BLO to pop the grain then a tack coat of Shellac is applied before waterborne lacquer and polyurethane.

Some of them are waterborne polyurethane made from whey protein (VNC PolyWhey). Some are waterborne lacquer (Target Coatings EM6000)

This was an experiment to learn how to use a spray gun to apply finish.

The open form sweet gum bowl was mostly turned by Jerry Sambrook in my shop

Great looking set of bowls.You did an excellent job on turning.

Very nice bowls and seems to me you have the finish application under great control.

Thanks, it was fun playing with the spray gun. Here is another that just cured enough to put in the light tent.

Mystery wood bowl. Got the wood from the estate of a local wood-turner. All the projects made from that estate will go to the Free Wheelchair Mission which auctions them off to raise funds to give wheelchairs to people in developing countries. Finished with EM6000 waterborne lacquer.

Nicely done. I especially like the shape of that cedar piece. The finish looks great on that one as well, and I've always had trouble finishing cedar. Thanks for sharing.

Pretty bowls Eric, are you using an HVLP gun?

That is a piece of spalted oak, is it not Eric?

Thanks everyone.

I don't think so, it is open grained like oak but lacks medular rays. It was very pale white between the spalt lines before putting on an initial treatment of Bush Oil. It may be spalted ash, but I was not really sure, so left it as mystery wood.

Pretty bowls Eric, are you using an HVLP gun?

Yes, a conversion HVLP with a 1.5mm needle. I have a small one that can run on 5 CFM and since the pieces I use it on are small like this my undersized Makita compressor is good enough to drive it. Waterborne finishes like EM6000 / PolyWhey need big needles because they have higher viscosity than solvent based finishes like Behen Lacquer.

The way I did the finish on the cedar piece was start with Bush Oil to pop the grain, waited a week then wiped down with DNA, followed by spraying a coat of shellac to serve as a binding agent between the oiled cedar and the waterborne polyurethane. Per general guidelines on waterborne finishes, I had to make the shellac from flakes as the stabilizing agents in liquid shellac like Zinnsser shift the pH to the point where waterborne finishes craze like a broken car window.

Nice looking bunch of bowls. Gotta say the Sweet GUM is my favorite.
