Hi @john101,

Welcome to the Workshop community. It's great to have you with us. 

Sounds like a great project! We are looking forward to seeing it come together. Hope you can share some photos with us along the way. 

Let me tag some helpful members in @LePallet, @ProjectPete and @Brad to see how they might best tackle this one. Can I ask what the hole is for?

Budget option

Cheap and nasty

Drill small holes around the edge of where your 32mm hole would be and break the plug out then file/grind it to size.

I have a set of holesaws that miss 32mm that will work with metal and a TCT set that has 32mm but isn't made for metal and some step drills, I would go with a step drill as they tend to be neater finish that a holesaw. I have done the drill and file method more than 23 years ago.
