Caution When Buying a Spray Gun

I was teaching a hands-on finishing class, including spraying, a while back when a student brought me a spray gun he had bought a year before from another teacher who was selling a line of spray guns. The spray gun wasn’t working right and he couldn’t figure out why. We fixed the problems, but...


How Myths get Started

I’m bouncing off of Chris Schwarz’s August 25 blog post where he describes how myths can get started. I’ll leave you to read what he says, but basically Chris realized that a simple joke can lead to a myth that gets repeated everywhere and never dies. Chris is talking about the woodworking world, which is...


Is it the Object or the Finish?

I got a call recently from a friend who runs a mid-size woodworking shop. He was making several dozen walnut tables for a restaurant and finishing them with pre-catalyzed lacquer. He sent off a sample of the finish to the restaurant owner, who came back with an objection. The restaurant had hired a professional...

Here is the front cover of his book.

Books on Repairing Furniture

As I mentioned in a previous post, I had good woodworking skills 40 years ago when I started doing furniture restoration, including furniture repair. But repairing furniture is different than making it. So how did I learn good repair skills? I learned them from a number of excellent books, which showed me good practices...


You Read it Here First: Pee Back Paint

In my first blog post I told you about a new smart-coating technology that causes liquids, including pee, to bounce off surfaces. In the case of pee, it bounces back onto the perpetrator, so it’s used to discourage people (men) from peeing on walls in public places. The example I used was from the...


Introduction to Restoring Furniture

It has been my intention from the beginning of this blog to include postings about furniture restoration. By restoration I mean wood repair (including regluing), finish repair and refinishing. For twenty years, from 1976 to 1995 I ran a one-man (me) furniture making and restoration shop. I opened the shop with the intention of...


Brush Lifts Stain While Brushing Finish

This may have happened to you. It’s surely happened to me. When you’re brushing a finish, the brush picks up some of the stain and lightens the wood. It’s even worse when the brush picks up so much stain that it leaves streaks. The first solution to try is to let the stain dry...


Hyper-slick Coating

So I’m sitting at dinner trying to get the last of the ketchup out of the bottle pictured here when I noticed that almost none of the ketchup was left stuck to the inside of the container. The plastic was almost perfectly clean. Then I remembered reading about the new technology that was responsible...

Shown here are three types of shellac in already dissolved form and five colors of shellac flakes for you to dissolve in denatured alcohol

Shellac is Not Bug Poop!

OK, it’s a small thing, but I still get irritated when I see or hear shellac described as bug excretion. It’s not (think of the related word “excrement.”) It’s a resinous SEcretion (big difference) from a bug that feeds off of plum trees, which are native to South Asia. The bug secretes the resin...
