All log homes need sealant to close the gaps between log courses. Because even machine milled logs won’t lie perfectly flush against one another, these sealants are necessary to prevent water intrusion and provide insulation. These sealants typically fall into one of two categories – chinking and caulking. Today we’ll compare the applications for both of these sealant types.
This is the type of sealant that has been traditionally used in log homes for centuries. It forms the characteristic white bands between the courses in older log homes. Whereas chinking was originally a Portland cement-based mortar, today it is an acrylic compound designed for extra elasticity and adhesion. Before chinking can be applied, a backer rod must be placed in the space between the log courses. This ensures a firm seal between the joints. Next, Chinking is applied over the backer rod, filling in the remaining gaps between the logs. The width of the chinking in a given log home will depend on its construction and the aesthetic preferences of the owners.
This type of sealant is only used in modern, machine-milled log homes. It’s very similar to the caulk you’ve probably used in your bathroom or kitchen. Whereas chinking is designed to fill broad gaps between courses, caulk is used to seal narrow gaps. Likewise, it doesn’t require backer rods. The caulking in a machine-milled home is more or less invisible from a distance. Caulk is also more elastic than chinking.

The first consideration is the scope of work or project. If there is a plan to make log railings or furniture as a business venture, then purchasing a higher quality but more expensive tool may be the right choice. If this is just a weekend project at home and the tool may seldom be used again, then a minimal investment would be preferable.
Lumberjack Home Series, Lumberjack Commercial Series, or E-Z Tenon Cutter
Lumberjack Industrial Series or Lumberjack Pro-Series
In it for the long haul:
Northwest Manufacturing Tenon Cutter
The profile style a tenon cutter leaves on the wood stock can vary by brand and series. Some people prefer to see the two logs butt directly against one another, while others prefer to see the taper from the full stock down to the tenon peg inserted into the other log.
90º: E-Z Tenon Cutter 90
60º: Lumberjack Commercial Series, Lumberjack Industrial Series
45º: E-Z Tenon Cutter 45
Radius/Radius Shoulder: Lumberjack Home Series, Lumberjack Pro-Series
|90-degree shoulder (E-Z 90 shown)|
|60-degree taper (Industrial Series shown)|
|Radius Shoulder (Home Series shown)|
The size of the wood stock and the desired size of the tenon are two considerations when choosing a cutter. If one was to pick just one size of tenon cutter, 1-1/2” is probably most versatile. For most furniture having a 1” and a 2” tenon cutter would be preferable. Some projects with larger or smaller logs might require larger or smaller tenon cutters.
The E-Z Tenon Cutter gives an adjustable option to get a variety of sizes out of one tool. With other tenon models, you would want one, two, three, or more tenon cutters to use for cutting different components of the log project.
Most of the tenon cutters on the market will have options of size to fit the project. The three considerations listed above, plus a summary of each tenon cutter brand listed below may help to narrow your choice:
90º or 45º E-Z Tenon Cutter: Steel and aluminum construction.
Pros: Adjustable tool that can cut a variety of sizes (1” – 2-1/2”). Dual blade for 90º model. Comparatively inexpensive.
Cons: Requires an extra step of drilling a 3/8” pilot hole. The final product may be a rougher cut and require some sanding. Single blade on 45º model.
Pros: Inexpensive option. Self-centering design. Dual blades that cut twice as fast as ordinary tenon cutters and generate less heat for long lasting service. Blades of hardened steel. 1/2 inch steel shank is threaded for easy replacement. Lifetime warranty for body and shank. Blades are covered for 90 days from the date of purchase for breakage under normal working conditions.
Cons: No IN-SIGHT measurement system (viewing slot on side) to monitor length of tenon or to insert quick-stop bolt. Fewer size options.
Pros: Self-centering design. Dual blades that cut twice as fast as ordinary tenon cutters and generate less heat for long lasting service. Blades of hardened steel. 1/2" steel shank is threaded for easy replacement. Patent pending IN-SIGHT measurement system of slots and radial grooves at 1/2" intervals for measurement of tenon length during cutting. Lifetime warranty for body and shank. Blades are covered for 90 days from the date of purchase for breakage under normal working conditions.
Cons: Higher cost than Commercial Series or Home Series.
Northwest Manufacturing Tenon Cutter: Cast aluminum.
Pros: High quality construction, long lasting. Adjustable shaft to allow custom sizing of the length of the tenons. Two high carbon steel blades.

When using an Albion caulk gun for bulk caulking or chinking application, leather is a one-type-fits-all material for packing cups and is included with the gun. The packing cups are the plunger-type component that pulls the sealant into the barrel of the gun and pushes it back out. In some situations one may choose to replace the leather packing cups with a different type of material. Here is a general guide for when to use which cup:
#21-1 Leather: Low friction, tough and durable, excellent chemical resistance. Soak in motor oil to maintain. May swell then break down when used with water based materials. Oil more frequently or choose another packing cup for acrylics.
#21-7 Impregnated Leather: Similar to soft leather cups but stiffened with wax to reduce water absorption and blow-by.
#21-16 Nitrile Rubber: Good seal, elastic, moderate friction. Excellent for water-based materials. Preferred by chinkers. Not recommended for use with solvent-based materials.
