For boxing out the pillars and bottom sides to take the panels on vans, carts, etc., a right- aud left-hand router, as Fig. 1, and two or three of various sizes for boxing or cleaning out, as Fig. 2, are required, as are also a few ordinary firmer chisels and a good mallet. For taking out a corner pillar on one edge only, set the iron in the grooving router (Fig. 1) to nearly the depth required, adjusting the distance on the pillar by the iron fence oh the bottom; this has a stud welded into it which works through a slot in the handle, being kept in place by a wing nut on the top; run this to the depth set. With the mallet and a chisel, knock out the wood to form the rebate, using the chisel bevel side downwards, when the wood will work out quite easily; take it down to the depth of the groove, set the iron in the boxing router (Fig. 2) to the depth the recess has to be, run it along the pillar, keeping it flat on the face, when it should clean the wood out square and true. Where a rebate has to be made in a bottom side to take a panel, two grooves must be made with the router, keeping just inside the lines, chopping and cleaning out as already described, cleaning out to the gauge lines with a T-plane, trying the panel while the work proceeds to ensure a good fit.
