How to Predict that a Wood will Blotch

A common question is: “How can I know if the wood I’m using is going to blotch when I apply a stain or finish?” This question comes up most often when finishing cherry, which has become a very popular wood. The solution is actually rather simple. Anytime you wet wood, you create the same...

Aerosol Finishing Products

It took me a long time to realize the full value of finishing products in aerosol cans. Not only can you finish an entire object with these aerosols, especially if the object isn’t large, you can also use them as an easy barrier coat when the finish you’re brushing has the chance of lifting...

Smart Coatings: On Land and Sea

Picture a military vehicle such as the tank shown. To help disguise it, it is painted with colors that blend in with the surrounding landscape. Problem is, the vehicle might move to a different landscape during battle, leaving it more exposed. So researchers in Australia have come up with a coating that changes colors...

Hide Glue Part 1: Overview and Introduction

You can’t really talk about repairing antique furniture without explaining hide glue because it was the glue used on almost all furniture made before the 1950s. So, with this post I’m introducing what I hope will be a series of posts in the coming months on hide glue. I’ve written about hide glue many...

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...

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...
