So, my wife has a framed piece of embroidery we got from a garage sale. The erstwhile owners thought it was junk, because the stand was broken. Hah.
I thought I could make something of it. First, I cut the base flat. This was freehand on the tablesaw. Not recommended. Had I been doing something more aggressive than shaving off high points, I would have done it differently. Result: flat bottom.
Now, a base. Start with a block of wood: planed, jointed… otherwise quite square.
What I’m going to be doing here is using the square block as a guiding surface to cut a precise sacrificial rectangular shape, attached to the work piece. Then I’ll be able to cut the work piece, guiding off the sacrifical piece.
Two-sided masking tape is remarkably strong; more than strong enough for the next 10 minutes of work.
Work piece temporarily attached to the sacrificial block. Now, I make an offset fence, so I can cut the block a carefully measured amount proud of the edge of the workpiece. You can see the configuration here:
About 7/8″ clearance between saw blade and edge of fence.
OK, now we run the workpiece by the saw in every direction, and cut the sacrificial bit to 7/8″ proud, everywhere.
I want a tapered leg effect, and a taper to the whole base. So set the saw at an angle.
This is a shopsmith; without entering into the religious debate about them, I find it a fine tool. But if you want to do a taper on the tablesaw, you’re going to be tilting the table. Now, make the penetration in the zero-clearance throat plate; I want this piece well supported.
And, I’m ready to make my cuts around the edges of the workpiece. Here you can see the blade approach angle to the workpiece. I’ve got it raised _just_ high enough to make a thorough score into the sacrificial piece. You can see a notch out of the top of it, for a sense of how deep the blade is going.
Now, carefully, cut all four edges. Because of the cut geometry, no blade guard is possible here.
Now, increase the tilt a little,
Move the fence a little, and raise the table a little; this cut is not going all the way through the workpiece.
and again four cuts. Viola!
That was the interesting bit. Now, it’s just careful dado work.
to clear the bulk of the waste,
and then a _LOT_ of sanding.
Then, to attach the base to the embroidery: drill two _pedantically_ carefully measured holes in the base.
(with drill press, natch) and then drill the same holes in the shaved base of the embroidery.
Cut a few short brass pins, and give them a skewtch of a taper on the drill press in horizontal-boring configuration. I’m gripping the pin in my hand drill.
and a few gentle taps with a little hammer, and we’re done.
Item in service.
