Local farm supply shop has a 8 in Genesis brand bench grinder on sale for $44. Next to it is a Dewalt for $140. The Dewalt has much beefier rests, but that is all I can tell. Is $44 a good price Or a piece of junk...
I don't own a grinder or one of those big Scotchbrite wheels and get along just fine. Don't see any reason for them, frankly.
But do get a long Vixen file - that's handy.
I can fully deburr a wing rib in less than 90 seconds, where other people take 10+ minutes. Multiply that times hundreds of parts and it adds up.
I do agree with the vixen file. That is the first tool I pick up when starting preparation on skin edges.
Are you deburring absolutely everywhere in that 90 seconds, Scott - e.g. in between all flange tabs?
I don't mean this as a put down personally, but that can be why some people take 800 hrs to build an RV-12 and some people take 1200 hrs.
Some processes, that If properly learned, can save a huge amount of time.

An A&P friend said that he always thought it important to debur until he climbed into the tail of a Cessna and found all of the sharp edges. I wasted lots of time deburring my RV-12. In some cases, deburring might do more harm than good if the alcad coating is removed from adjacent surfaces. Burs should be removed where two parts meet to prevent one part from scratching the other one. It is nice to be able to work on the plane without getting cut by sharp edges. If a part is so highly stressed that it depends on deburring to prevent cracking, then that part needs to be redesigned. Has an airplane ever crashed because parts were not deburred? I do not know, just asking.For some, the act of deburring is a fun unto itself. For some its a motion that must be accomplished to get to something else. For Piper, Cessna, Beech etal of the 70's and earlier, it was an act never done.
