I tried putting a veneer on a Regal headstock couple years ago and failed miserably, several times.
I could never get a clean edge/corner, it'd chip/crack when trying to cut it flush.
Not sure what exactly went wrong (it wasn't my first time applying a veneer) but:
- that headstock shape had very sharp corners, so it's very easy to chip the veneer there.
- the contact cement was one of those 'green/environment-friendly' alternatives (it's CA so that's what I found back then at Woodcraft) that didn't stick near as well as real contact cement.
In hindsight:
- I should have practiced on scrap wood cut to a similar shape as the headstock, with a few holes drilled too to see how cleanly the veneer could be cut once applied.
- I should have avoided the 'green' water-based contact cement: veneer + water = pretzel
So, practice on scrap wood first ;-)
