Use a dedicated lap steel set intended for the tuning of your choice. Do *not* use a regular guitar set, as the tension will be inconsistent and the resulting sound will be terrible. [GHS](http://www.juststrings.com/ghs-lap-e.html) makes a good set for open E, and [Pearse](http://www.juststrings.com/johnpearsehawaiianlapsteelguitar.html) and [SIT](http://www.juststrings.com/sitstringsnonpedallapguitar.html) make great sets for other tunings.

Um... a [SIT c6th set](http://buy.sitstrings.com/c/tbd_non-pedal-lap-steel?action_type=switch_product&selected_cat_keys=31182.100662.0.0.0&selected_product=1e1d2b58e1a2594035b6fea027f3dfa6&redirected_post=1), maybe?

I'm restoring a Supro/Valco/National lap steel from the 50s. Anyone have tips on what I should string it up with?
