The European jointer plane I bought for $20 has some issues. Foremost is the fact that the rear portion of the sole is de-laminating. Likely not that unusual, considering the style of the “V” joint used, which is simpler than other European methods of laminating a sole to the body of a plane.
Below is view of the wound on the side of the plane, Due to the angle of the grooves (which seems about 70°), it produces a wavy pattern on the side of the plane. This can lead to damage along the ends of the grooves (which can be seen below).
The second issue has to do with some cracks which show up in the ends of the plane. Wooden planes are of course subject to drying, and wood contraction, like any wooden structure. This could have occurred due to a quick construction, or it being stored in a dry environment. Either way, the cracks do not seem to pose a huge problem for the plane, as they have not surfaced. For a tool that is likely 100 years old, this isn’t terrible.
There are no cracks in the throat of the plane. This part of the plane is just grimy.
The third major issue has to do with the plane’s handle, which for one is slightly off-centre (a sign of reduced quality?), and has a slight vertical warp, likely due to the cracking present in the handle.
The handle is joined to the body of the plane with two (rusted) screws. Is this a sign of reduced quality?
Last but not least, the plane blade is covered in corrosion.
