Just a quick update on dog-hole drilling.
I decided on a 2 fold approach.
First I drilled about 5mm of every hole using the 19mm forstner bit, the Axi drill stand mounted on a quick jig and an electric drill.
I then changed to a 19mm spade and drilled the whole depth, however after hitting a screw in the third hole I had to change to an 18mm for the other holes
Finally I changed back to the forstner and reamed out the holes to a nice finish.
Worked great but I only managed 13 of 26 holes in the space of about 2 hours work.
