The first thing I do when building a glockenspiel frame is mark out where the notes will be. From these marks, I know where the note pins will be going, so can position where I want to fix the note rails to the base board.
Now I can drill clearance holes through the base board, and counter sink them on the underside. I have only ever met a few people who use clearance and pilot holes; coincidentally I also have respect for their work. Most people can’t be bothered (good reason!)
The clearance hole allows the screw to pass straight through the base board, so when it goes into the note rail, it will pull the two parts together. If no clearance hole is used, the fixing will screw through the board and rail simultaneously and therefore not pull the two parts together. This is really very basic knowledge, and should be a given, sadly it is not. Next time you need a tradesman, see if they use them, if not, find a new tradesman (good luck!)
The next step is to get the note rails on, and mark them out for the note pegs.
I then remove them to drill the pilot holes for the note pegs.
Pilot holes are used to stop the wood splitting. They are the same size as the core of the screw to be used, so that only the flutings cut into the wood.
After the holes are drilled I put in braces front to back to support the note rails and prevent them from falling over. At this stage I put the notes on to have a look at everything.
I like the combination of the oak on a black background, so I will varnish the frame.
