Applying ShellacThe following link is a follow up to the August demonstration on applying shellac to your woodworking projects.
In this video you will see where shellac comes from and how it’s made and sold to market. It’s about 12 minutes long and well worth watching.
Here's The Video
Incra JigThe following links are follow ups to the September demonstration on the Incra Router and Tablesaw fences.
These videos demonstrate the setup and use of both the Table Saw and Router Systems in use. Excellent videos, you will wonder how you ever got by without owning one or both of these. Hey Christmas is right around the corner! Take note that there is a systems that pulls double duty when your router is mounted into your table saw extension wing.
Router Table Cabinet BuildThese video show the complete money is no option, wiz bang parts, to build yourself the router table system for all to envy.

Winter Finishing TipsFrom Our Friends At Finisher Warehouse
Now that we are looking at another few months of cooler temperatures, we thought we'd do another installment of best practices and winter time finishing tips. Given that Phoenix weather can shift almost 80° from summer highs to winter lows, there are some unique challenges to wood finishing during these months of milder temperatures and increased moisture.
• While starting early is optimal in the summer, in the winter, that is obviously not the case. With humidity at its highest and temps at their lowest, spraying before 7AM from November through March is very difficult, since wood coatings are best sprayed at temps around 80°. If you're able to shift your finishing production to after 10AM, when the temperature is generally above 60°, you'll find it is much easier to avoid orange peel, and possible blushing, in your finish.
• Coatings storage and handling are vital during the winter time. Wood coatings become much more viscous under 80°, as they are not able to flow properly after atomization at the gun. How can you avoid these issues? Simply setting pails on 2x4s will insulate them from colder ground temperatures. Storing in a warmer room of your shop will help even more. Keeping your coatings warmer will ultimately lower their viscosity and allow them to perform as expected.
• HEAT! Having a warmer environment in your shop is extremely beneficial when finishing in the winter. You'll have to be creative in order to achieve the best finish. We strongly discourage using any type of catalyst propane heater (the "jet engine" models come to mind) when working with solvent based coatings. Recipe for disaster. Start by opening south-, east-, and westward facing doors as soon as the sun hits so you can get some much needed heat into your shop. The best solution is using heating lamps during cold mornings. Using a lamp on your surface before spraying is a great way to start, and putting the lamp over the material after application will cure the coating faster while also helping to level more effectively.
• Just as solvent additives can correct the issues we see during the summer, the are also important for solving problems in the winter. With colder temperatures, we are looking for additives that decrease viscosity while also allowing the lacquer to flow better after being sprayed. These additives also increase the time before the coating "skins" over and will help prevent orange peel from appearing in our final finish. The lower the evaporation ratio number (the closer to 0, the better), the slower the solvent evaporates from the coating, giving a longer open time for improved leveling. Come ask use what would be the best additive for your specific application.
• One more tip about thinning. It can be beneficial to keep a journal of different blends of retarders and thinners for specific dates, times, temperatures and conditions. One season of note taking can really help you going forward.
