   Padauker,

   I've used my angle grinder for that and much more. I use a Makita 4 1/2" that I got at Lowes for around $50, and the sanding disks offered there as well. I would not get a variable speed model. Tried one out at the store and thought it was VERY poorly made. Instead vary the pressure (angle grinders can be used with a lot of finesse) and use a finer grit if the sanding is going to fast. If you need to remove a LOT of wood just to rough out the shape, the 'arbor tech pro' bit works well. If using the arbor tech, I'll go to 36 grit then maybe to 120. Can't remember if he said it in the article, but don't stay on one spot for very long or you will burn the wood and sometimes trash the sanding disk due to glazing. Oak is one of the worst from my experience; especially end grain.

   WEAR A FACE SHIELD!!!!! and work outside if you can.

   ...and enjoy working outside the box. Strait lines are over-rated.

   -Kevin

   I have 4 angle grinders and would recommend you get a 4-1/2" as it's the most common size and will work with the most add on accessories. Woodcraft has a variety of wood grinding tooling to choose from and each manufacturer has sanding pads and such. A 5/8" 11 threads per inch arbor size covers a broad range and places like http://www.mcmaster.com will stock all the sandpaper and backing pads. Comparing the highest amperage of the motor will yield the strongest motor but it's kind of splitting hairs.
