JUUMA Bevel up Planes Dieter Schmid Werkzeuge GmbH www fine tools com P 15 It is important that the flatness of the sole is preserved To assure that a large flat surface with abrasive properties is necessary This can be done with wet dry sanding paper that is taped onto a perfectly flat surface i e thick plate glass granite window sill etc Make sure to remove all unevenness from the sanding paper like price tags etc Ensure that the movable front portion of the sole stays in place and is well tightened The blade stays in the plane but is pulled back to no cutting depth That will ensure that the plane is in the same shape as it is when used as the tightened blade warps the plane ever so slightly Now the plane is pulled over the wet sanding paper If necessary a very coarse paper with a grid of 80 can be used at first The last paper should be very fine at least a grid of 240 After the lapping the blade should be removed and it and the entire plane has to be dried and oiled properly to prevent rusting JUUMA Bevel up Planes Dieter Schmid Werkzeuge GmbH www fine tools com P 162. This jack plane has a combined Norris type cutting depth and lateral adjustment The spindle has two successive threads The thicker one screws into the spindle retainer that is anchored into the plane body The thinner thread is screwed into the dog The shaft is connected to the blade and moves it along Both threads are right handed but with a different pitch To advance the blade turn the knurled head 2 clockwise Turning the knurled head counter clockwise will cause the blade to retreat There should always be moderate tension on the blade don t over crank it To prevent inadvertent movement of the blade always try to adjust from thinner to thicker Even when the shaving needs to get thinner it is better to adjust down past the desired thinness and then increase the width 3 3 Lateral adjustment for an even cutting depth along the entire width of the blade This adjustment is always necessary when the blade is reinserted into the plane As an example this adjustment would be done after placing the blade back into the plane after sharpening Lateral adjustment is done by pivoting the blade minimally at the leading edge until the cutting depth is even along the entire width of the blade Sometimes this adjustment is also necessary while working to correct an initial askew mounting of the blade or to counteract a divergence in the right angle between cutting edge and side of the blade Because of the low angle of the blade beddin

17. reaker This style requires a shallow wedge to be integrated onto the body of the plane between the bed and the sole This design leads to a very thin edge on the rear portion of the mouth and thus wood is not strong nor ridged enough for bevel up planes This is why bevel up planes are always made from metal such as cast iron In Germany planes were traditionally made from wood so bevel up planes were largely unknown until cast iron planes from the United States were imported to Europe Bevel up planes are too narrow between bed and sole for a frog to fit This is why the mouth opening is adjusted with a sliding sole instead graphic 1 right A bevel up or bevel down blade in a plane is not an indicator of quality but rather provides woodworkers with very different performance characteristics Bevel up characteristics Bevel up planes are much flatter due to the shallower angle of the blade That leads to a more comfortable usage especially with one hand That is why the very popular one handed cast iron planes are usually bevel up The blade is fixed in the bed up to the cutting edge and thus kept in a very stable position This will prevent chattering even when working on hard wood as the bevel will not get caught in the material The plane performs very quietly under any conditions There is no chip breaker as with a bevel down plane Instead the angle of the blade bevel can be increased to make the cutting angle will be much larger
