Well all I can say is I've finally got pretty far with my 1st build , what a learning curve

!!
I'ts taken longer than I expected and it's not over yet


.
I'm about to route pickup cavities / do tuner holes / and do a little more neck shaping . Then I'll be at the final sanding phase and that is where some advice would be great .
I've used walnut for the top and see that it is quite a grainy wood that does not seem to sand to a really smooth finish ( perhaps it's just my lack of experience ) , does anyone have any advice on how to prep the walnut to smoothe it out for finishing ?
I'm thinking of perhaps using tung oil !
