Spent a couple of hours on the monkey build this evening. The goal was to get the bridge installed but that involved a couple of other jobs too, Started off by reaming out the tuner holes so I could test fit the sperzels and later check that the bridge is drilled accurately.
Then I needed a nut to put my strings in if I was going to test the bridge... I've always used Graphtech and never bothered with cutting/slotting my own from scratch - the price of nut files seems hard to justify when a Graphtech nut is £10 and is almost perfect out of box every time. But Adrian wanted ivory coloured appointments (pickup rings, switch tip) and I have a load of bone nut blanks (one of the ebay sellers I buy fretboards from throws one in with every order) so I figured a bone nut would look good on this build. I got the Crimson nut file set and their string spacing ruler during their last sale and finally got round to using them tonight.
Making the nut was quite enjoyable but man, it's was time consuming.
Dusted off the disk/belt sander - first time I've used it in an age, but really glad I had it for this job.
I rounded off all the exposed corners and stuck it in place with a drop of super glue.
Then I marked the string locations with a pencil and the string spacing rule and made a light cut with the razor saw so I had a start.
Then I got the bridge location marked out and a couple of 11mm holes done with the hand drill. I used a couple of squares to ensure I was drilling plum
Bridge all good so I got a set of strings on, it's now officially a guitar
Then I spent a good hour on filing the nut slots. On the slots where I had a file that was slightly bigger than the string gauge, I got perfect results. But files that were the same gauge as the string were a bit awkward, eg the 26 and 10 gauges - the string would bind in the slot and be really difficult to get all the way down or to pull back out again, fortunately I realised that before I went too deep on any of them. So I played around with rocking the file side to side to widen the slot slightly which work well.
I think I've still got a bit too much height on the nut, the string slots are pretty good, but the overall height of the nut (making the slots deeper) was clearly contributing to the strings binding. So before I do the final assembly, I'll file a bit more off the top of the nut, it all needs a good sanding and polishing anway.
I still need to do fret levelling, crowning polishing etc yet but I'll let it hang on the wall with strings on for a while, get it used to it's new shoes.
That was an enjoyable evening of learning, all be it time consuming. I think I'll have to revisit the ziricote build at some point and make a bone nut for that one too.
