The Murphy Builders Site

Hello Group,

Sorry to trouble you with such an entry level question, but I have very little metal working experience and don't want to screw up.

I am about to add pump-outs to the float compartments on either side of the main wheel wells. My natural impulse is to use a cup-shaped hole saw, as one would for wood. (http://www.canadiantire.ca/AST/browse/6 ... RRWidgetID)

I am just a bit worried that the saw may start to "walk" sideways in the thin aluninum of the float.

So, here I am, looking for re-assurance, or alternative suggestions.

Thanks in advance.

John
