I have a little 3/4 size acoustic that im getting for free. thought it would be kool to make it into a lap steel. the bridge is supposedly messed up and the neck is warped. as far as a lap steel that shouldnt matter (from what i understand).

question is what is needed. obviously a string changed a thicker nut. any ideas on what size or type to buy for this and anything else that would be needed.

any help is appreciated.
you'll most likely need to replace the bridge saddle in addition to the nut, you'll have to raise both high enough that you can put a good amount of pressure on the strings and still keep them off the frets. other than that it should work fine
