Options for Finishing Cherry
Note: I currently have a Binks Mach M1-G Prime HVLP gun that is designed for shooting automotive primers and waterborne woodworking finishes. The gun has a 1.7 needle (no smaller available). I'm under the impression that this gun has too big a tip for pre cat lac.
From Paul Snyder, forum technical advisor:
Water-base finishes don't have quite the same grain "pop" as oil-base and/or solvent based finishes and can look dull on cherry and other woods (some WB finishes are better than others).
But it's easy to work around this limitation. Instead of getting a new spray gun and using lacquer, you can either seal the wood with shellac or an oil-base product. Shellac does a nice job of popping the grain and figure in cherry and, depending on the type of flakes you use, adds some color as well, which also enhances the wood. Oil-based products, on the other hand, do a great job of enhancing the directionality (aka chatoyance, shimmer) in the wood and bringing out its color. Boiled linseed oil is often recommended, but its slow dry/cure time is a real deterrent in a production environment. Instead of the linseed oil, I use an oil-base varnish; it's dry in a day. I use Waterlox original sealer and finish because it has a deep amber coloring that really pops the figure.
Here are the steps I use:
I'm working on some large horn speakers for a customer and he loves the look of the oiled cherry with topcoats. I just completed a bunch of cherry display cases for him using the same finish.
From contributor T:
DL M1-G also comes with a 1.4 needle. I have both with the 93P cap. The atomization of a pre-cat lacquer is a whole other subject, like Magnamax in the previous posts. Many precats don't spray as good as your regular lacquer or CV. Heating them in a metal cup helps (85-90 F). You should be fine with your tip to spray it. If anything, you'll have a faster laydown.
From the original questioner:
Thanks for the responses. Looks like I have some options. I think I'll set up some samples and try the different methods before I get a new gun.
