Of course, I just HAD to learn how to put a Basswood arrow through the hole of a Danish coin! And, no, I won't tell you how it is accomplished - that would spoil the mystery. You'll just have to figure it out for yourself, like I did!

The following impossible object puzzles were done by Bob McQuaker of Edmonton, Alberta, Canada. He likes to put his wooden arrows through golf balls, glass and multiple objects. Note how thin the glass is on a light bulb, or how a golf ball is made…and these are even MORE amazing!

Now, if I can just get him to explain his wooden intersecting pliers!

On the left are light bulbs with double-headed wood inserts. On the right are two bottles with arrows and one bottle with a solid wood piece too large to be inside it.

On the left are wooden arrows through double golf balls, an arrow through a metal washer, a wooden arrow through a buffalo horn, and a pair of wooden intersecting pliers. On the right is an arrow through both a golf club and a golf ball.

Now here is a mysterious puzzle that I would like the answer to:

I've been told that this is a Polish joke, an oscillating sander, and just about everything else...

It's a half round sanding drum, approximately 1/2" thick, 7/8" wide,and 2 1/2" long. It has a 1/4" diameter steel shank. The overall length is 4 1/2". On the shank is a two piece die cast (zinc?) drum and on the end of the piece is a knurled nut that expands the two piece drum to grip the half sanding sleeve.

The shaft is easily inserted into a drill chuck, but I can't imagine it being used while spinning.

One guess is that it was used on a scroll saw to convert it into a sander for flat surfaces and inside curves (but how would it fit?)

Another guess is that it fits on an oscillating sander that moves up and down only, but does not spin. I think it could be used for sanding internal scalloped edges.

Just what brand/model and type of machine is this HALF ROUND SANDING attachment used on? But where does one buy sleeves for this???

Any info on this would be appreciated. I have TWO of these.. but only one has the sanding sleeve on it. This piece is probably worth a small fortune as a conversation piece. I know I have gotten a lot of mileage out of it.."

I have lots of wooden impossible and mysterious puzzles in my head that I want to cut out and show you, too. Hang in there...I'm sawing just as fast as I can!
