for nailing oak i use either a Pin gun or a Micro Pin gun, have no problem with oak from 1/4" to 1 1/4" thick. rarely use trim thicker than that, but have nail guns too. I know what i'm talking about, i build custom Chancel furniture- you know, the fancy furniture on the stage in a church. have pieces in just about every state in this country and a few foriegn countries too! Tim, sometime when you come by, i'll take you to the shop and let you play with the big shapers...........
