For exactly the reason I stated above sir. Inexperience. My last issue was because I *thought* I had 33" of width for the panel. Well, I didn't. So I had to use other material to add on. I needed to get it down to the same size. I don't live in a perfect world where I know what I'm doing 100% of the time. At least, not in this area. I am not going to call it a needed tool, but I'll take the extra convenience.
I agree with Coop...Wixey gauges are a waste of space. All of your boards that need to be exactly the same thickness should be going through the planer at exactly the same time, and who cares what that thickness actually is? Do without it. Matters not.
Excellent article Eric. It appears most of the mahogany I've used over the years is indeed African (very nice to work). I thought so but nice to have it confirmed. I'm going out to the shop to inspect some pieces I obtained a few years back to look at that end grain for parenchyma. It may be that I still have some genuine in stock! I do like sapele bearing in mind that interlocking grain can be a problem. Thanks for posting this.
