|Base The base is a scrap of ¼" plywood
(or hardboard) thats ripped wide enough to accommodate the workpieces, as
you can see in Figure 1. (I cut mine 6" wide.) This creates a reference edge thats
used to position the fence. Note: You can make the sled whatever width is required
for the workpieces you are trimming. Just don't move the rip fence once you've
cut the reference edge.
Fence The fence is made up of two scrap pieces. To position these
pieces, lay out the line you want to trim to on one of the workpieces. Then, align
the mark with the reference edge on the plywood. Finally, butt the fence pieces
against the edges of the workpiece and glue them to the base, as shown in Figure
2. Note: Hot melt glue works great for this.
Trim Workpieces Now you're ready to trim the workpieces. Just slip
one in place against the fences and then run the sled along the rip fence. Note:
In my case, the workpieces were mirror images. So when I trimmed them, I could
stack the two mating pieces together, as you can see in Figure 2.
