Hello Rob,

Thanks for the tip about the cut off wheel on a die grinder. Last night I found a mandrel online that fits the 3 inch cut off wheels and works with a die grinder - as you suggest. I also saw an online article - which I can of course no longer find - that warns against using cut-off wheels on die grinders. It might have been because of the lack of safety guard.

I tried one of the "Multiple Purpose" tools which has a plunge cut-blade and a flush cut blade. The result was pretty underwhelming. I reckon I should have collected some ants and put some honey on the welds. Their efforts would have been more effective in cutting through the welds.

Thanks for the suggestion about epoxy. I was thinking of some Sikaflex products when I previously typed in "Sealant".

Kind regards
Lionel
