Fig. 202 shows one corner of a mitred and dowelled frame. It needs
little or no explanation beyond the fact that the dowels should be at
right angles to the line of joint, and consequently the dowel at the
outside edge of the frame will have to be much shorter than the others.
This gives a strong and serviceable joint, suitable for many purposes.
FRAME DOWELLING.--Fig. 203 shows one corner of a frame with long and
short shoulders, such as occurs when the upright is rebated through its
entire length. The holes in both pieces are bored for the dowels before
they are rebated. This avoids any difficulty in endeavouring to bore with
only one side of the twist bit in the wood. A similar type of joint is
used on nearly all kinds of glass and door frames in cabinet work.
Fig. 204 is a leaf for the screw type of table. Circular dowels are shown
at one end, and rectangular wooden pegs at the other; both methods are
equally good, and, of course, the dowels are only glued into one leaf.
The object of these dowels is to guide the table leaf into its proper
position when the leaf engages the table proper, and to make the flat
surface of the table top and leaf register correctly and thus ensure a
level surface.
Fig. 205 is a wooden block made in two portions and held together by
screws; it is used to fasten around a twist bit, the object being to
ensure that all the dowel holes are of uniform depth. It may be adjusted
as desired and firmly screwed round the twist bit; if the hole is made
1/4 in. in diameter it will clip round a 1/4-in. or 3/8-in. bit and will
answer a dual purpose. It is a preventative for bad dowelling.
Fig. 206 is an example of dowelling framing when the moulding on the edge
has to be mitred. It is necessary to cut the shoulders away so as to
allow the members of the moulding to intersect. The section of the mould
is not shown in the sketch for clearness of representation. The portion
marked H is called the "horn," and it is not cut off until after the
frame is glued up; its object is to prevent the rail splitting or
bursting when knocking up the frame or during the cramping process.
Fig. 207 shows the method of dowelling a moulded cap to the top of a
wooden bedstead post or similar pillar where it is desired to avoid any
unsightliness.
Fig. 208 is a dining-table leg and portion of the framing, showing the
method of dowelling the frame to the leg. Chairs, couch fr
