Trapping Planes

The Trapping Plane is used to taper and modify cylindrical lengths of wood produced by the rounders. It was developed from a wooden device used for making greenheart fishing rods in the Redditch area of Worcestershire.

It is made in cast aluminium and has a pivoted lever which when gripped, raises a wooden vee block bringing the wood to be tapered in contact with the cutter. The trapping plane can only be used on round wood which is rotating. It traverses as the wood is rotating and is able to form tapers on wood from 1(3/4)" (45mm) down to (1/4)" (6mm) diameter.
Good eye judgement is needed for a pleasant and even taper. The surface finish is good on most woods when the material is rotated at speeds ranging from 200 - 400 rpm, the speed of rotation being dependent on the diameter of wood to be tapered. The larger diameters require slower speeds whereas a thin back stick for a Windsor style chair can be tapered successfully at 400 rpm. When tapering thin sticks, there is no need for a back steady as the material is 'trapped' between the sliding beechwood vee block and the body of the tool, thus eliminating any whiplash.

Shaping a chair leg

The trapping plane can also form barrel shaped components or slightly waisted shapes on legs, rungs, stretchers and other chair parts. When forming tapers, the rounded material is held only at one end in a single chuck with no need for a tailstock. This means that tapering and shaping can be achieved on lengths of material which are longer than the lathe bedways.

There are two types of trapping planes:-

  1. The Standard Trapping Plane - which is used with our own turning-head or handcrank, or on lathes which have a reverse facility.
  2. The Lathe Trapping Plane - which is used on ordinary woodturning lathes where the wood is rotating towards the operator and there is no reverse facility.

Both are priced the same. The only difference being in the position of the pivot lever.

It is important when ordering a trapping plane that you specify which type you require.
