Re: metal vs wood jointer
Christof Hartge
>Hello Mathurin,
I vote for a wooden jointer, although to give truth honour, you won't see a difference in the results of work between a wooden or a metal jointer.
The main question is: What do you want your jointer for? There three main tasks: 1. Edge jointing. 2. Surface jointing 3. Surface smoothing.
If you want one jointer for all three tasks take short jointer, that is comparable to metal, no 7. Specifically the Ulmia short jointer with 50� pitch is a good one. Also you won't do wrong with the ECE short jointer and a C&W.
The argument of flatness: As Wiley pointed out. A good jointer moves very little. I scrape them every sixth months. The amount of wood taken away measures in hundreth of a millimeter.
Over the last time I specialised my wooden jointers and made good experiences:
1. edge jointing
Requirements: Lenght 24" or even more, Pitch 45� or lower, mouth opening: doesn't matter much. Blade shape: dependent on edge technique straight or slightly rounded.
Here is my ECE jointer in action, blade straight: http://www.woodworking.de/schaerfprojekt/brett1-3.html.
2. surface jointing
With surface jointing I mean the jointing after the Scrub Plane has done his work. This plane is also called Try-plane.
Requirements: Lenght: around 18", blade shape: rounded, Pitch 45�, mouth opening: wide.
3. Big surface smoothing
Requirements: Lenght: around 20'', Pitch 50�, mouth opening: fine, blade shape: very slightly rounded. Here the Ulmia short jointer in action:

Now to the argument of mass: If you want to do fine work as edge jointing, the shave will enroll itself with nearly no effort, or something is wrong. If you do heavy work with a try-plane, you'll be after half an hour work gratefull vor every spare weight, you won't have to give momentum.
Greetings, Christof.
