Useful Device for Rebating and Grooving


FIG. 1. HOW THE APPLIANCE IS USED. The arm A fits over the far edge of the work and is held by the wing nuts Y. Note that the work overhangs at the front edge.

This is an excerpt from “The Woodworker: The Charles H. Hayward Years: Volume IV” published by Lost Art Press.

Anyone using the Stanley or Record combination and multiplanes, or indeed any form of rebate or grooving plane, will no doubt have experienced difficulty in holding the work in position when it is too small or too awkward to be held in the vice. Here is a gadget that is extremely useful in overcoming that difficulty.



Made of hardwood, it is capable of accommodating material of almost any length, up to 15 ins. in width, and of thicknesses varying by sixteenths of an inch from 1/4 in. to 1-1/16 in. The one side of arm “A” (see Fig. 2) takes pieces 1/4 in., 1/2 in., 3/4 in., 1 in., thick, the other 3/8 in., 5/8 in., 7/8 in. Intermediate measurements from 5/16 in. to 1-1/16 in. can be obtained by inserting a 1/16 in. thick washer under arm A. Other measurements can be arrived at by using thicker washers, though 1 in. is normally ample, anything thicker being suitable for the vice.

The diagrams show the construction of the device and call for little comment. Arm A is attached to slides E by 2-1/2 in. bolts, the heads of which are sunk. Note also that the head of bolt X is sunk below the level of pieces B and D (see Fig. 3).



To attach the device to the bench it is necessary to cut a number of mortises, 1-1/4 in. by 1/2 in., 6 ins. apart along the edge of the bench. Where the vice is flush with the edge of the bench the mortises will have to be cut in the bench top, but where the vice projects any distance an extra fitment can be screwed in position. The mortises in no way interfere with normal work, and once cut require no further attention. Two hardwood stops  are then all that are necessary to hold the device rigid on the bench. These should be about 4 ins. long and a tight fit in the mortises.



The method of use is as follows. Attach the device to the bench by means of bolt X passed through one of the mortises. Now drive the stops into the adjacent mortises, allowing the one towards which the planing is to be done to project above pieces B and D. This will act as a planing stop. The rear stop is driven below the level of B and D and serves merely to prevent the device swivelling due to lateral pressure. Here it may be noted that the outer edge of piece B projects a little over the edge of the bench as in some cases it may be required to act as a guide to the plane. Where a long strip is being rebated, for example, the front stop may be driven below the level of B and D and, the device being fixed in the middle of the bench, the bench stop used as the planing stop.

The work is placed on top of the device, its near edge projecting slightly beyond the edge of B and its end against the planing stop or the bench stop. Arm A is slid up to the far edge of the work and bolts Y tightened. Fig. 1 illustrates the method. By this means the work is held rigid.

In some cases, when the work is narrow, the construction of arm A does not permit of the work being clamped down, as the projection of A interferes with the plane. The method then is to reverse arm A, as in Fig. 4 in which case it serves merely as a lateral stop and not as a cramp.

    Awsome post Megan, I’ve used a board with nails in it in the past, this will certainly take the place of it.
    I recently paid to have Haywards how to make wooden tools printed but still needs work, it has a simular solution to grooving the narrows.
    I’d love a L.A.P version of the title.
