suite a variety of angled passages the pocket hole projection can be a peg 14 installed into the base 16 by a like pocket hole drilled therein or as in fig6 10 a rod 114 which is removeably inserted into an angular hole in the base 11 screw head 224 is attached to the distal end of projection 114 and the screw head and projection are thereby removable the clamping action is accomplished differently in each embodiment in fig1 5 a lever clamp 30 is affixed to a sidewall 32 of the base lever 34 when actuated moves a preferably resilient adjustable bumper 36 into contact with a second workpiece 38 the frictional contact between the bumper and workpiece claims the two workpieces 38 20 into place usually the purpose of such clamping is to allow adhesive between the pieces to dry adhesive is often used in addition to a fastener which is screwed nailed into the pilot hole the structure of lever clamp is shown as a scissors type with multi point pivots but other structures can be used the bumper 36 preferably has an adjustable contact height as shown by threads 40 in its retracted position the bumper is retracted away from the workpiece which it is intended to engage and in its engaged position it is brought into contact with such workpiece to create a compression.
