Hey guys, I'm currently doing my first built together with my Grandad. He used to do a lot of wood and metal work back before he retired so he's got lot more experience than me. Trouble is, I think his eyes must be going. I got a gorgeous, bookmatched Pacific Blackwood top for this superstrat that we're building. The only problem is that, as I left him to glue the two pieces together as all the tools were at his and I was busy, there seem to be a few gaps. My own fault I know, but I really wanted a natural finish for the top to show off the grain. By the time I next got a chance to work on the build he'd already glued it to the mahogany back. Basically, what I'm asking is what would be the best way to go about disguising the gaps? Is it just a case of grain filler or has anyone got any insider tips?
