the above image is of a rig I set up for uniform cutting of wooden strip into blocks that will act as reflectors for the otical sensors. The following image shows the location...

I prefer the idea of wooden triggers, either balsa (for it's lightness) or spruce (pine/fir), a it would be more inkeeping with the original design of the keybed than my second option, if indeed they are the right size as I am not sure having not opened up the board again to measure yet...
I have on order white square bungs/caps 10mm x 10mm outer diameter, 8mm x 8mm inner diameter. However I'm not sure if white would be a suitable reflective colour for the optics? This option would be easier as it would not involve all the cutting. There are advantages and disadvantages for both, but as I said, my preference is the former option.
Upon study, I can see that it will not be necessary for much in the way of modification in order to achieve the correct positionings of sensors in relation to triggers either in terms of distance nor angle. It will be just a simple matter of setting the angle of the PNOscan strip so that when the key is fully depressed, the modified triggers will be parallel to it, and adjusting these triggers so that they are exactly .06inch (width of two creit cards) above the sensors (when the keys are fully depressed).
The only other modifications will be for wiring routing, setting up pedal sensors (unless some manufacture produces a quality midi tri pedal unit!) and fitting the console to the underside of the Keyboard.
Progress will be reported at each stage.
