FINISHING FORMULAS Some woodworkers keep a tight lid on their recipes, but we pour it all out. Some say that finishing can be a "ruination of a nicely built piece of furniture." Well, to build that piece you have to study the different technique s and have access to good plans. Plans and procedures are now shared openly by most woodworkers. But when it comes to finishing, some of the best woodworkers slip into a secret back room and never let their exact procedures see the light of day. How are you supposed to become a better finisher if you are not shown the techniques and formulas? That's why we are "blowing the doors off" this little-shared but highly important aspect of woodworking. This article is an all-access pass to the finishing methods I've used for a number of projects from my books and magazine articles. Sand less Than You Think All finishing starts with the sanding, and I think that many of us sand more than necessary. Once you move to a paper that's finer than #180 grit, you begin to close the wood pores, which will affect the stain's penetration. Because these stains depend on soaking into the wood to obtain the best results, sanding too fine should be avoided. I hope that's music to your ears because most of us complain about sanding. What's important is to remove all imperfections, so while you don't need to go past #180 grit, you do need to sand effectively to gain the upper hand. I use a random-orbit sander and begin with #120 grit, if necessary, and move through the #150 and #180 grits, followed up by hand sanding with #180 grit, making sure to move in the wood's grain direction. Also, use sandpaper to knock off any sharp edges on the project because these will show wear first. A homemade Wipe-on Finish for a Clear Topcoat Once the sanding is complete we can move on. Some projects require that you add only a protective clear topcoat. I have used the commercial products that are available for a wipe-on finish, but I keep returning to my own mixture. Why?
