W & H 154 Operator's Manual - page 7
When planing the edge of stock, a high, square, relieved guide is needed in order to
have the edge reasonably square and to provide
stability. Use center reliefs to reduce friction.
Some profiles are too deep to make on the W&H. In
some cases you can rotate the profile into a flatter
position to effectively reduce the depth of cut.
A “vee block” guide would be made to guide your
stock. The profile knives would have to be custom
made to use in this vee block position.
When making tongue and groove stock, a serious and detailed approach is
needed in order to achieve a uniform fit. Carefully pre-inspect your stock for
cupping and warping. You need to plane all your stock to one uniform size.
The guide thickness should be 3/8” thinner than your stock or your roller will scuff on the guides when the
stock has left the machine and the rollers are in their rest positions. When running thin stock you will need to
fasten a sub-plate between the guides to maintain a thick enough guide to control your stock.
Always check your knife clearance to the guide. Clear away any interfering portion of the guide by gently
lowering your knife down into the guides to just below your running position.
MOLDING PICTURE FRAMES
Decide whether the rabbet or profile cut should be done first. If you are going to make the rabbet on the W&H
Molder, do the rabbet first. In order to utilize the W&H Molder for rabbets, a rabbet knife with a depth of cut
equivalent to the depth you need should be ordered. If we do not have a standard knife with the depth you seek,
we can make a special knife to suit your needs.
ROUND TOP CASINGS OR
CONSTANT RADIUS SIZE ARCS
We manufacture knives with the profile cutting the deepest portion of the cut on the open side of the machine.
Notify us when you order a knife if you want the deep side of the cut on the vertical tube side of the machine.
The set up and operation of the W&H machine for a round top molding job is very similar to the straight
molding set up. The main difference is the stock is attached to a template that raises the stock up for the knife to
clear the jig hardware. Our EJ92 Elliptical Jig is not needed for a fixed, constant radius.
Stock preparation can be done in many ways. The following is one example.
First determine the angle needed to cut the wood sections in order to stay within the selected radius. Lay out the
wood sections by marking the angles while being careful to select cuts for grain structure and color. Cut the
sections and biscuit join them together with glue.
We made a fixture to band saw the inside and outside radii consisting of a pivot bar and bracket. We mounted
the pivot bar to the stock on the scrap portion of the inside radius. The pivot bar is drilled with numerous holes
to accommodate any radius sizes. You may also want to design a fine adjuster to allow you to make any radius
in between your adjusting holes. Make sure the outside radius is cut first.
