Early version of a raised panel jig

OK I couldn't find the "clamping" part of this jig but once again it is one I made way back in 1976 as part of my learning about my new shopsmith. While I had been using table saws for a while already I want to see just how things would go with my new toy. What better way then to make some jigs for it.

While the title calls it a raised panel jig it has a lot of other uses as well. Maybe you can already picture them? How about if you wanted to make some glass stops out of some smaller wood, say 1/4" thick and 1/4" wide.

You could clamp this say an 8" piece to the fence upright (grain running the proper way) and adjust for a cut that left you with the 1/4" material between the fence and the blade. Now you could set the blade to say cut 2" deep and make your first cut. Now flip the work piece end for end and do it again. and now rotate the board and make two simular cuts leaving say about an inch of material down the center of the work piece uncut. Gee that's easy to do and safe.

Or how about some tenons? I'm sure by now you can start picturing a lot of other things one might do. If not wait until spring and ask me then.

Since one of the critical parts of mine is missing lets look at this first:

This very close to what I have. Here are a few pictures:

In the first picture you can see general shape of the jig. This one designed for the old 500 would need extensive reworking to be used on one of the newer machines so a rebuild would be in order... you might find it quite different because of the t-slots on a 520...

The second picture shows a wood clamp but that would not be my first or second choice of clamping methods but could work.

In the third shot you can see the row of holes that lets you locate the bolts near the workpiece to clamp it better. This is great for taller pieces but for shorter items it might require a wider clamp board... you can't tell very well since that piece is missing.

So I've spent my evening doing posts here except for a supper break and watching an hour of TV. Now this is about it for now unless you have some questions.

Hey, I think I see an application for this thing already!!!!! Very nice looking work. Few questions:
  1. Would one expect near perfect perpendicularity of the raised vertical fence to the table without any form of shimming?
  2. Woodscrews used for assembly?
  3. Glue up the joints during assembly?
I have a pallet with 1" plywood top that is just dying to be cut up and used for a project like this.

So your first choice would be the bolt on hold down show in the link picture, and your second would be ????

Hi,

The idea behind making this jig is to have it be right without the need for shimming. However if the rip fence is off ie twisted or not perpendicular then you might have some issues to deal with. If you have a problem it is best to deal with it after we find a cause...

The online PTWFE has instructions towards the end of this section:

This is a revised edition of what I have. Mine is only 21" long, perhaps a better match with the smaller 500 size table. Mine also lacks the vertical bar which I think I'd add if I ever make another or refurbish this one.

All of my old 500 jigs were never expected to be reused when I upgraded to the 520 so some have become other things or have missing pieces or in some cases even missing screws which is the case with this jig... only held together with glue at this point. Of course now that I have a 500 in the shop again I have been trying to find them and wishing I hadn't scattered them to the wind.
