I have had a Lie-Nielsen Iron Miter Plane for a few years. Having a shooting plane is kind of specialty plane but as I got into using hand tools more and more, I appreciated a simple system to clean up and square up the ends of boards.
Last week I bought a Veritas Shooting Plane, which is a brand new plane. Lie-Nielsen offers a similar model but there are differences.
The Lie-Nielsen Iron Miter Plane is a simple design. It's basically a long box with a plane blade sticking out. The blade is square and presents it's cutting surface square to the shooting board. It has a handle that can be swapped from side to side depending on using the plane left or right handed. It weighs about 4 1/2lbs.
The Lie-Nielsen No. 51 Shooting Board Plane is very similar to the new Veritas model. It has more mass at more than 9lbs. The blade is also square but presents it's cutting surface at a skew, 20 degrees. This makes for simple sharpening but gives the advantage of cutting at a skewed angle, especially on end grain.
The Veritas Shooting Plane has a mass almost 8lbs. It has a square blade and like the Lie-Nielsen No. 51, it presents the blade's cutting angle at a skew of 20 degrees. The handle is adjustable while the Lie-Nielsen is not. It is available in a left and right handed model. Lastly, it has an adjustable mouth to help refine the cut.
In use, I found that the handle on the Veritas Shooting Plane gives it a much more controllable push through the cut. I had the handle in the upright position, similar to the Lie-Nielsen. I didn't find the adjustability in the handle to be a big plus and used it mostly in the upright position. Compared to the Lie-Nielsen Iron Miter, I found it much easier to push through the cut.
Compared to the Lie-Nielsen Iron Miter, it was much simpler to get a clean edge with the Veritas Shooting Plane. I think this is primarily due to the skew angle but I really liked the ability to adjust the mouth too.
I haven't done a complete sharpening on the blade but, like the Lie-Nielsen Iron Miter, I like having a square blade to sharpen versus a skewed blade.
I am going to sell the Lie-Nielsen Iron Miter plane soon as the Veritas Shooting Plane fits my needs better.
When buying Lie-Nielsen or Lee Valley/Veritas products I rarely get to try them out unless the need is near a Lie-Nielsen Road Show. With either, I am never disappointed with the products. The Lie-Nielsen Iron Miter is a great product but the differences with either the Lie-Nielsen No. 51 Shooting Board Plane or the Veritas Shooting Plane give the advantage to the latter two.
I think the Veritas Shooting Plane has the advatage over the Lie-Nielsen No. 51 Shooting Board Plane for 2 reasons. First, the adjustable mouth gives more control over the cut. Second, the Veritas Shooting Plane is about $200 cheaper.
I'm working on 2 desks and really expect to enjoy using the Veritas Shooting Plane during these projects.
