Need to fit some rod holders to the boat today.
fortunately for todays hole...45mm I have a 43mm hole saw. I am sure once it is done it will be closer to 45 than 43.
2 problems..1 there is a 12mm hole in the centre where I need a 4.8mm hole. Solution use yesterdays method and create a new hole with a small piece of Ali.
Problem #2.....the rod holder must be at 55 Deg meaning I have to drill the pilot hole through my Ali at 55 Deg, What is the "agreed" method of drilling a hole at 55 or any angle for that matter through a piece of steel? Fot this project it would not matter if the hole is a mm or so off as the drill is pressed to the side.
ps I know I can drill the hole in the boat square and then use the pencil grinder to get it to the desired angle that is not the point of this question.
