Veritas Bevel-Up #1

This is the Veritas Bevel-Up #1 plane, which I have been using for a year now. With a 1 7/32″-wide blade, it is indeed small but it works legitimately as a seriously useful plane. An ancillary tool, not a necessity, still I reach for it a lot more than I expected, so I want to share its merits with readers.  

This plane excels for small or concentrated work where its maneuverability and the vision of the work that it affords are significant advantages. In fact, even large projects involve plenty of detail work, such as a leveling touch-up at the shoulder of an assembled mortise and tenon, and fitting small components, especially those involving angles and round-overs. 

What makes this plane worthwhile for me is the feel. While there is some crossover in function with a block plane, this plane is different. Getting both hands in non-cramped positions on the handles of the BU#1 away from the sole affords feedback and control that I really appreciate. I can readily feel the tilt, and I like the excellent visual clearance. I also find that it handles significantly better than the Stanley style (bevel-down) #1.

I keep the BU#1 tuned about like a smoother with the blades mildly cambered. Because there is little momentum behind this small plane, it is particularly important to keep the blades sharp, especially if using a high attack angle.

This plane has a 15° bed so you can sharpen with a secondary bevel of 30° for a good all-round attack angle of 45°. It is also useful to keep a second blade sharpened to 40° or 45° for a 55° or 60° attack, respectively, to use as a touch up plane on difficult grain. The short sole helps in this function. By the way, I would prefer a 20° bed but I’ve covered that issue at length elsewhere

Other features that I like are Veritas’ Norris-style combination adjuster with set screws near the front of the blade to make responsive lateral adjustments, and the adjustable front sole plate with a retainer set screw to easily regulate the width of the mouth. The sole of the BU#1 that I first received was slightly but significantly concave along its length but Lee Valley, being the great company that they are, exchanged it without bother. I slightly touched up the sole of the replacement, just because I’m picky. 

The BU#1 does not suffer from the unfortunate handle design that plagues most other Veritas planes. (They can be replacedtalk to Bill Rittner.) It has only a mild curve but this works well for this plane; it feels right and comfortable to me. 

My usual disclaimer: This review is unsolicited and uncompensated. My goal is only to point out good tools so you can make great stuff.

glue flexibility

Wood, and thus wooden joints, moves with moisture changes, and since we put pieces of wood together with glue, it is worthwhile to consider if the glue itself flexes. In other words, how elastic, or stiff and brittle, is the glue itself? 

Here, I want to look at differences among PVA glues, which in almost all discussions get lumped together without attention to significant differences among them in the property of flexibility. Here is a nice simple demonstration.

As background, we know that at one extreme, urea formaldehyde glue such as Unibond 800 forms a rock-hard, extremely strong, rigid glue line making it the best choice for bent laminations. Hide glue also forms a quite hard, rigid glue line. PVAs are, in general, more flexible.

I spread four different glues into approximately one-inch discs on a birch plywood scrap, and then let them dry thoroughly for several days (photo above). From left to right:

Titebond Liquid Hide Glue

Titebond Original PVA

Titebond III PVA

Lee Valley 2002 GF PVA

The Lee Valley glue is a PVA that is claimed to have gap filling properties. I have had good results over many years with this product. Titebond III is touted for its water resistance and as a good all-round wood glue. 

Working on the discs on the plywood, I could not dig my thumbnail into the surface of the hide glue. Even pushing as hard as I could, I could not make a mark. The surface also cracked as it dried. 

The Titebond Original was the second hardest, taking a lot of pressure to make just a trace of marks. Titebond III was clearly the softest of the four; it was easy to dent with my thumbnail. The Lee Valley 2002 GF was intermediate between the other two PVAs.

I also spread discs on a piece of silicone “tape” (non-adhesive wrapping). After they dried for several days, I gently lifted the discs away, which had almost no adhesion to the silicone. I then curled and snapped them (photo below).

The results were consistent with the thumbnail test. The hide glue was the most brittle but Titebond Original was a pretty close second place. 2002 GF was intermediate; it could snap or curl depending on how I deformed it. Most interesting, Titebond III did not snap at all. No matter how I deformed it, it was quite flexible and only curled.

The simple point here is to show that there are distinct differences in flexibility among PVA glues. How you use that information is another matter. Depending on the type of joint, its dimensions, the wood properties, and the intended use of the piece, you may want more or less glue flexibility. 

Also, this is a separate issue from the strength of the glue bond. There are also several other properties of glue to take into account when choosing among them. 

Now this is obviously not a scientific test. However, I trust my observations in the shop and watching how pieces fare over the years as much as I trust some of the elaborate tests in woodworking magazines. My personal take away is this confirms what I noticed about Titebond III, which is that it is quite flexible, and so I’ve learned to avoid it in certain situations. Titebond Original is a better choice when you want a more rigid glue line and water resistance is not important.
