Stefan, with the quality of your handles I hardly think people could complain even if they have to wait for a few months

As for drilling, no I didn't drill this handle before glueing. At the moment I predrilled only 2 prototypes with metal spacers and dowel and can't drill anymore, as I need to buy another drill bits (broke 2 bits from the crappy cheap set of drilling bits I bought locally).

I wish I could find someone like Dave here to do installation for me
