I had posted something in the Asian Guitar area about adjusting the string spacing at the bridge on my Kent. For the benefit of anyone who stumbles across this later I'm going to move it to the projects section and tell y'all what I ended up doing - unscientifically and with little in the way of proper tools - in case the info is useful to anyone.
I wanted to force the strings to cross the bridge at certain places, in order to make the spacing more even and wider. I had considered cutting grooves into the plastic Kent bridge where they ought to be but was concerned that the bridge might be hollow and that cutting through to the hollow section migh be bad. I took off the bridge and determined that this wasn't a problem -- the bridge was solid plastic. Cutting notches into the bridge should be fine.
I moved the E strings until they were as far from the edge of the neck at the high end of the neck as they were at the nut. With the E strings in this position I marked the bridge at the point the strings crossed it. I measured between the strings and found that they were exactly 5 centimeters apart. This meant that I could put the ruler at the High E spot and mark the bridge at each centimeter to show where each string would cross with even spacing. There were already slight notches where the B and G strings crossed and they were in the correct location (or close enough) so I didn't do anything with those. The high E, low E, A and D all needed to have slots cut.
To make a starter slot I took a box cutter and held it over the gas burner on the stove for a few seconds, then pushed it into the plastic where I wanted the slot to be. This worked pretty well.
I then tried to use the box cutter to carefully shave a little bit of plastic away from the slots to enlarge them. Bad idea. The plastic is very brittle and twice, when putting sideways pressure on the bridge, small chips broke out of the bridge adjascent to where I wanted the slot. I was able to glue these back in with Super Glue and I'm hoping they will hold.
I tried filing the slots by wrapping fine sandpaper around the appropriate string for each slot and sawing back and forth. This tended to cut through the sandpaper before it cut into the bridge.
The best solution turned out to be using the string itself as a file. Sawing back and forth with the E, A and D strings in the starter slots seemed to do the trick. High E is OK using the slot I melted with the box cutter. I haven't strung it up yet, but I think it's going to work. Obviously something like nut slot files would have been ideal here, but I don't own any and buying a set would run me about $80, which I'd rather not spend.
The next step is to try making a pickguard for it. I ended up putting a set of DeArmond humbuckers on the guitar (they were already hanging around) such that I don't need the pickguard to mount pickups. I do need it to mount the jack and controls, and maybe to help shield the cavity. Any suggestions for easily workable pickguard material would be appreciated.
