Hi, how ya doing!

This NG your dad posted at does not have a lot of Scrollers because of the
general nature of this NG.

If you are enjoying the hobby of scroll sawing, why not go on over to a
couple of forums just for people who like the hobby.
This site is hosted by a scroll saw magazine Scroll Saw Workshop:
http://www.scrollsawer.com/forum/index.php?

This site is also a good site:
http://www.woodworkingcrafts.com/info/forums/index.php?

There are about 5 or 6 other sites for scroll sawers where your question
about 3-D puzzle for a beginner might be answered. Go ahead and visit and
read some post. You might just like the company there and want to join.

BTW: I know this is not at your level yet, but someday it will be:
