Dare I assume forstnered first and then hole sawed over the top?   You are indeed correct!

CNC, laser, trimmer/router or hand chiselled?  A mate did it on his Laser for me before I got mine.... I onlyy felt it right to use his seeing he went to the troube.

Thanks for the tips Alex I will use them next time.... cheers Gary  Next Build is the Road Grader, T&J one first before I attempt the Gatto ;)
