[Rhodes22-list] Stainless Steel Cutting Question

[Robert Skinner]

OK. 

Given what has come up in discussion so far, I'd go and buy a
bunch of grinding wheels and burrs for your Dremel, as
suggested by another writer.  I've used that little guy for a lot
of jobs. 

If you have a rotozip or can borrow one, you might check on
the new bits available for it.  I use my rotozip for fiberglass
repairs on the boats, but have not tried it on steel.

There's an internal flap/valve that needs attention. One could get access from the bottom if one removed the cold air/heat mix box, another item installed before engine installation.  I had some good sheet metal guys on my hangar row look at the problem and they all said, "cut an inspection plate and repair it from the top".  When asked how they all shrugged and said, "I do aluminum".  Plasma cutting would be the ticket but I'm not sure about the electrical grounding of the working material and the currents that would be involved.  We ran into this problem with our trackhoe when we welded the hydraulic thumb on, but that was a simple matter of disconnecting the "brain" while we welded.  Not so simple a solution in this case.  This is starting to shape-up into one of those problems
