| Sorry, can't help you with that information. Actually, I haven't heard of a dowel puzzle before. Good luck.

| The puzzle has 7 pieces and it is cut from a 1 1/2 inch dowel. I would post a picture of the pattern, but I don't think I am allowed to do that. I just wondered why I have to rotate it 15 to 20 degrees per instructions.
I did not do that and it came out o.k. I think.
Thanks for your reply eendreno and Tor.

| Just a guess here...maybe so the pieces are all turned a little as you go up the dowel, making all the kerfs on a different plane, so that it all fits together with less slop? My second guess (and yes, these are guesses because Im not sure what a dowel puzzle is)is that it should be turned slightly so the pieces only fit in from one side, but i think that would mean tilting your saw table. I dunno, I tried, a picture is worth a thousand words sometimes, this being one of those times! dale |

| Yes lucky788scroller it does have a bit of slop in it, so maybe you are on to something there. Thanks

| I believe the dowel is rotated so the tabs will interlock. It will keep the puzzle in tact when it is complete. I have thought of doing a similar puzzle for a blind friend of mine, who would love to do a jigsaw.

| Wood Dog, I have done several of them as gifts for puzzle loving friends (or maybe enemies after they tried to put them back together) and the reason for rotating the dowel around its long axis after each cut is to allow the tabs to be cut into the thicker piece of dowel that remains. It is much like cutting a 3-D piece in that respect. If you don't rotate the dowel, the tabs end up with too thin a neck and are liable to break off.
The hardest part, I found, was preventing the blade from bowing sideways as I cut the tabs. If it does bow, the cut needs to be heavily sanded or the piece only fits in one direction and that makes the puzzle very annoying to take apart or put together. A jig to which you clamp the dowel makes the job easier and helps keeps the dowel from rotating while you cut it. It also helps if the dowel is much longer than the final puzzle length. This makes it easier to hold in place while you cut. Just cut all the pieces, put them back together and square cut the two ends.
By the way, I found my pattern in Patrick Spielmans book Scroll Saw Puzzle Patterns page 220.

| Thanks sawdustus.....your technical explanation sounds reasonable. I'm going to try it again to see if it also will take the slop out.
BTW I got my pattern from Don Geary's book Getting The Very Best From Your Scroll Saw page 86
Thanks

| You can post a photo of the finished puzzle, or the work in progress, just not the pattern. I'd like to see what you're making!!
