There are so many jobs that used to be extremely time consuming, that have become a breeze with the Plek. Take fingerboard slotting for example. A fingerboard is always slotted before it's glued to an instrument. Because doing so after would require such complex and unique jigs that it simply wouldn't be worth the effort. Now, I can turn a fretless, finished instrument, into a fretted one with minimal extra work. I can curve the slots, so their bottom matches the radius of the fingerboard at any point, dictate the depth within 0.01mm, do a recessed slot, where the fingerboard looks bound, even though it isn't. What a wonderful contraption.
