Woodworking Press Cramp

Woodworking Press Cramp

It will frequently be found necessary to tightly press or "cramp", or clamp, pieces of wood together that may have been mortised and tenoned, grooved and tongued, or simply glued: we, accordingly, give a drawing of a serviceable cramp, which the amateur can make of any desirable size. He will only have to purchase the screw and nut-head.

Diagram I is a side view, showing the wood screw A, the nut-head of which, B, is securely mortised and tenoned to the bar C. The screw moves the sliding block D. At E is the stop-block, which can be roughly adjusted to the work to be cramped before pressure from the screw is applied. A bent loop, of three sixteenths of an inch iron rod, holds the stop-block securely against any possible pressure; and is released from, or fixed in the notches in the under edge of, the bar C, in the manner clearly shown.

The cramp should be made of oak. The amateur will find it worth his while to make several such cramps of different lengths, varying from 18 inches to 4 feet; the sizes of their several parts being made proportionate. Occasionally two or more may be required on the same piece of work at the same time.


For very rough work, in which great pressure is necessary, iron cramps must be used. These can be purchased at reasonable prices, of any size and of various forms.
