As I promised, the panel-raising jig is now finished. The basic structure is unchanged, but the addition of a vertical fence and a lever clamp converted the proto-jig into a tool for panel-raising. The clamp is the Quick-Set Heavy-Duty Lever Clamp from Rockler (item # 29485), which happens to be on sale right now for $9.99 instead of the usual $15.99. This might be a good item to stock up on for future jigs.
Don’t worry, the bottom screw hole in the fence doesn’t have a screw in it. It was a temporary holding point while the other screws were driven, and the clamp was attached. By the way, pocket hole screws are a great way of attaching something like this clamp to the project. Their washer-head design snugs down over the baseplate holes quite nicely and allow you to adjust things slightly if need be.
Now, I have to determine the specifics of how to set up to raise the panels. There are a lot of variables to take into account, so I’ll have to glue up a few test panels to work the details out.
