What techniques do you recommend for drying green wood prior to stabilizing? I will be stabilizing knife scales and blocks.

Drying green wood can be tricky, depending on the species.  I would start out by leaving them larger than you need to allow for shrinkage and warping.  Then you could simply place them on a shelf in your shop for 6 months to a year.  If you need to speed that up, there are many ways to do this.  You can make a hot box with a 100 watt lightbulb for a heat source and allow the blanks to stay in there for a week or so.  You could also do the same with a toaster oven if it will go low enough.  I would be looking to keep it around 100-120° F.  You could also look online for directions on drying wood in a microwave.  Many folks have had good success with that method.  Regardless of what method you use, once you get them "dry", you need to further dry them to oven dry state in an oven at 220° F for a minimum of 24 hours for best stabilizing results.
