There is a dimensional change with anodize that's small but noticeable where a thousandth or two makes a difference. However, my approach is different. I'd do the precision hole drilling AFTER anodizing, not before. That way the hole size will be perfect. Of course, it won't be anodized where the drill went through, but there's usually grease in one of these holes, isn't there? If not, and you're really concerned, you can always alodine the edge of the hole. There is a much bigger dimensional change with powder coating, possibly up to 10 thousandths near a hole (I don't know exactly). I'm not aware of noticeable dimensional changes with alodine. If you've got an aluminum spacer, like the ones in the 320/360 elevator pushrods, and the spacers fit prior to alodine, they will fit after alodine, too. By the way, any of the options (alodine, anodize, powder coat) looks better than zinc chromate primer, if you ask me.... - Rob Wolf >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please send your photos and drawings to marvkaye@olsusa.com. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
