Hello everybody, I have this nice medium scale (32") Warwick neck which I thought would be very cool as a fretless so I did the big leap and removed the frets. Removing the frets was a tough job as the wenge board is extremely hard. After removing the frets I placed some medium viscosity ca glue around the fret slots to keep chips in place and as a guide as to when I should stop sanding afterwards. The plan was to remove as little wood as possible afterwards and count on the factory levelling for a nice fretless board. After initial hand sanding with something like 400-grit sandpaper if I remember well, I put the bass back together. It's pretty good overall, BUT it has this effect as if there are still frets on the bass, that is, slight intermittent buzzing as you slide up a string. What has happened is that the glue has left small bumps that just could not be properly removed by hand sanding. So, according to plan, I bought a 20" radius sanding block and I am planning on continuing sanding using it. It's 8" long and *should* level the board completely getting rid of the ca glue bumps. I want to stick to plan, remove as little wood as possible and most importantly, EVENLY, from the surface of the board. A luthier has seen what I 've done up to now, measured the curvature of the board and thinks it's a pretty good job overall (he's a well reputed luthier mind you, but I have to confess I didn't mention that there are still little glue bumps he can not see haha). I am turning the truss rod until the board is near flat but with a little curvature still remaining, then the tough part: Using the radius block, remove as little wood as possible, evenly. Any ideas? I was thinking about using a weight on the radius block and doing full passes from top to bottom so that even wood is removed. Also thought about drawing and refreshing a grid with some chalk to track my progress, not sure if that will help or will be invisible after one or two passes. I don't have the expertise or more tools to do this "by the book" and I might have to go to a luthier after all, but hell, I 'll give it a try. Any help/ideas/corrections/pointers are welcome.
