re: Big Cabinets

Thanks Petey,  anything I can help with I would be glad to. Not that you need any,  you do quit well yourself.

Thanks Moke

Thanks L/W,  Honestly, I've never had to change any.  I buy Loox5 brand from Hefele' Everything plugs into a transformer so if there are ever any problems it wouldn't be hard to change out. Yes, access to everything.

Mark, I cheat with the shelf holes. 
I have a horizontal boring machine that drills the front and back holes at the same time. 21 holes in each row. It does have it's cons though when you want to customize the hole pattern.  You can remove bits as needed, but it's a pain.  When I need anything different I drill through a piece of 1/4" scrap material and use it for a template picking the holes I want.
