This is how the bottom of the keys look.
There are about 20 plastic pillars that are threaded. I'd really like to drill through the wood and screw into the pillars but I don't think I can drill the holes accurately enough so that they meet up.
This was my first solution to the problem, attaching batons which are countersunk for the screws. Then I was thinking of glueing down the batons to the board.
It would work but I think it is a bit ugly and there must be a nicer way. Even though you don't see this part of the construction it would bother me to know that there was a nasty botch underneath the surface. Guess I have a perfectionist streak in me :)
Any advice would be appreciated!

you can put something like a small pencil tip (from a refillable pencil) in all screw-holes and then put it over the piece of wood you want to attacht it to. then yyou got the exact location of the screw holes.
Why not use the case bottom as your template, position it over the wood and either mark through the original holes or drill right through them with a small, long bit. Then you could remove the case bottom and enlarge the holes to the size needed.
THanks to both anonymous!
Both ideas are good but I think the second is more good. The trouble with number 1 is that pencils really need to be centered exactly in the holes which are a few mm large.
The second idea is brilliant and simple. I'd totally missed the obvious!
I will temporarily glue the bottom of the case on the board. Then I insert a screw or thick nail in each hole and give it a whack which will give me an exact indentation.
Then the only difficulty will be to drill an exact vertical hole through the board.
Thanks for the comments :)
Make your holes slightly larger the needed, and use washers (or larger fender washers) to insure that the heads don't find there way into the holes.
Make sure you do NOT tighten the screws until all are started and you've "centered" the keyboard where you want it.
In more expensive wood cabinet pianos that use these jeyboards, that is EXACTLY what you have to do when you reassemble it following a repair.
Very nice job, Konaboy.
Looks like its a lot of fun to play, too.
