>Dennis,
These little one-piece guys are made from scratch. There's a comprehensive how-to article in issue 1 of Woodturning Design magazine from last year...you can still get a copy through the link below.
Yes, weight is important, but balance is critical. The two sides have to be virtually identical, and the materials have to be pretty uniform, otherwise you'll have a wobblier (uck).

There are two basic rules to follow when turning acrylic...1st, only turn "cast" acrylic, not extruded. The extruded stuff will heat up easily and cause lots of nastiness in your shop. Here's a simple test to tell if you have cast or extruded acrylic...cut a small piece off using your bandsaw. If the cut surface shows signs of melting, then you've got the extruded (bad) stuff. Rule number 2 is�to avoid dig-ins, blow-outs and a shattered-glass look, only use skews and scrapers, and make sure that the burr is removed from the scraper, or even better, put a "negative-rake" on the scraper's cutting surface. I use a 1/2" round-nosed scraper and 1" skew to make all these plastic yo-yos.
BTW, there's a link below to the outfit I get all my acrylic from...good, reliable service and the prices aren�t bad either. If you decide to buy some cast rod, go for the "machine grade" (cheaper) stuff...no need to pay extra for a polished surface that you're going to turn away.

>Thanks Ed! I turned an acrylic yo yo a while back using nothing but a 7/16" detail gouge with a very long fingernail grind. It worked OK, but nothing special. I'll get some rod and give the scraper and skew a shot.
Thanks,
Sam
