Flattening and smoothing of larger wide faces are effected in the working steps:
- surfacing,
- finishing.
In the case of surfacing, the coarse unevenness of the cut surface is planed:
- very uneven and rough surfaces are first planes by means of the jack plane and then by the smooth plane;- surfaces being uneven and rough to a smaller extent are planed by the double plane and the adjustable iron fore plane.
Finishing is the removal of last irregularities and smoothing of the surface by means of the double plane and the adjustable iron fore plane:
- the plane iron must cut a thin shaving only,
- the planing pushes shall be effected as long as possible and
. must be placed in parallel,
. must overlap each other a little bit.
Why is it only allowed to cut a thin shaving when finishing?
__________________________________________________
When planing a workpiece to the required thickness, then:
- the face facing the trunk centre is planed first;- the dimension of the thickness is marked out by means of a marking gauge on the narrow faces starting from the planed wide face;
- the opposite wide face is planed by means of the jack plane, the double plane and the adjustable iron fore plane up to the marked thickness.
