The wood can't be adjusted, but the frog can, which means that the cutter will flex backward as the plane is pushed forward, likely chattering, when the frog's face is not co-planar with the bed.
The frog is adjustable, but in order to take advantage of this feature some modification to the bed must be made.
Due to the design of the frog (it sort of looks like the ones used on the iron planes, but is shorter along its bed length), in conjuction with the use of wood as the body, the cutter can be unsupported for a good length when the frog is moved forward.
Whatever the reason, I've seen many totes on the wooden planes that are very loose.
The totes on these planes are normally found cracked and broken.
The larger metallic planes have a small machine screw at the front part of the tote, while the smaller metallic planes have a raised nib cast in the main casting.
Both of these features help to overcome any lateral twisting of the tote.
The wood - knob, tote, and body - are made of beech, and often covered with a very heavy varnish that practically obliterates the wood's grain.
The plane's number is stamped (incised) into the toe, usually along with the company's name and, on the earlier examples, an eagle.
On the earlier models of this class of planes, those made prior to ca.
1915, the screws used to hold the frog to the plane are wood screws and have round heads.
To overcome this problem, Stanley recommended that a shim of cardboard or veneer be glued to the bed to make it co-planar with the face of the frog.
