Introduction

17 August 2017

I've owned this jointer for nearly twenty years and during all that time, it has never skipped a beat since I first tapped the ON button. It is also the only jointer I have owned. Over the years I have also discovered that this particular jointer is not perfect. I'll get to this later below. However, that has not held me back from completing all of the woodworking projects I have taken on since I bought it.

I have also been forced to disassembled and assemble this jointer twice. If you've never had to do this consider yourself very fortunate because this task is not for the faint of heart. A move to and from Chicago necessitated the dismanteling of this machine due to its weight.

The Details

The jointer came with HSS knives installed and in no time at all, they became dull. Quite honestly, I do not recall if I purchased a new set of HSS knives to replace the original set or not. I do know, however, that I used my Tormek to sharpen these same knives several times and that worked very well saving some cash in the process. But, sharpening these knives gets old in a hurry regardless of how much money is being saved. Truthfully speaking, its not the sharpening that's a pain, its the knife installation that gets you down. More on this below.

In due time, I switched over to carbide knives from Global Tooling. While carbide does last longer than HSS knives, they become dull as well and have to be replaced because they cannot be sharpened on my Tormek. I think I installed two sets of carbide knives. These cost just over $100 a set and my current set of knives are dull once again. Today, I decided to switch to a Byrd Shelix cutter head. I'll log my thoughts on this radical cutter head after its installed and I've had a chance to test it out.

Knife changing

Now, regardless of which knives are used, installing them can be a bit daunting. The goal to jointer knife installation is to get the sharp edge of each knife in the same plane as the outfeed table is in. To make this task a lot simplier, I purchased the iGaging mini Mag digital height gage as seen below.

What you see above is the iGaging mini Mag height gage with its height-sensing arm resting on the edge of one of the jointers knives.

This tool is a snap to use. You first rest the arm on the surface of the outfeed table to zero it. Then you rest the arm on the ends of each knife, make your adjustments, until the readout displays "0.000" or thereabouts.

What I have found is that if all of the set-screws and the cutter head gutter(s) are perfectly clean and free of all debris, the adjustments will go much smoother. Dirty gutters tend to hang the knives which is not what you want. I first use an alcohol soaked cotton-tipped swab to clean the gutters. I back off the set screws so the knives are slightly below the outfeed table. I then use a plastic-tipped hammer to gently tap the knives so they are seated against the set screws and then snug the bolts slightly, and then use the set screws to raise the knives (at each end only) until they both read "0.000". This reading guarantees that the knife is in the same exact plane that the outfeed table is. After you do
