Always check your knife clearance to the guide. Clear away any interfering por on of the guide by gently lowering your knife down
into the guides to just below your running posi on.
MOLDING PICTURE FRAMES
Decide whether the rabbet or pro fi le cut should be done fi rst. If you are going to make the rabbet on the W&H Molder, do the rab ‐
bet fi rst. In order to u lize 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 CONSTANT RADIUS SIZE ARCS
We manufacture knives with the pro fi le cu ng the deepest por on of the cut on the open side of the ma ‐
chine. No fy us when you order a knife if you want the deep side of the cut on the ver cal tube side of the
machine.
The set up and opera on of the W&H machine for a round top molding job is very similar to the straight molding set up. One main
di ff erence is the molding stock will ride piggybacked on a template to enable the knife to clear the jig guiding hardware. Our EJ92
Ellip cal Jig is not needed for a fi xed, constant radius.
Stock prepara on can be done in many ways. The following is one example.
First determine the angle needed to cut the wood sec ons in order to stay within the selected radius. Lay out
the wood sec ons by marking the angles while being careful to select cuts for grain structure and color. Cut
the sec ons and biscuit join them together with glue.
We made a fi xture to band saw the inside and outside radii consis ng of a pivot bar and bracket. We mounted the pivot bar to the
stock on the scrap por on of the inside radius. The pivot bar is drilled with numerous holes to accommodate any radius sizes. You
may also want to design a fi ne adjuster to allow you to make any radius in between your adjus ng holes. Make sure the outside
radius is cut fi rst.
The guides should be 20” long, which is the length of the GS2 guide system, or 14” long if you are just using
the bed of the machine. The guides may be made using the band saw set up. We make one guide for the in ‐
side radius and one for the outside radius. We use MDF board.
ROUND TOP SETUP
1.
Make sure power supply is disconnected
2.
Raise the machine head and set the stock on the bed.
3.
Align the stock with molding pro fi le.
4.
Lower the head to pinch the stock.
5.
Set the guides and clamp them in place.
Raise the machine head, remove the stock, and reset the head to within 3/16” of stock size. Check to see that the rota ng knife will
not hit anything you don’t want it to on start up.
NEVER a empt closed loop molding. It is an unsafe procedure; you will not have enough roller pressure ini ally.
