Jim,
Another very good idea, and did think of that myself. The slot is a little
restrictive and may require a experienced Tig welder to do the job - without
flaws. A local chap used to Tig weld tips on Turbine blades, so he would be
good for this application - however with welding and then regrooving the
costs are getting up there.
I believe the cheapest you would get the slots recut would be about $50 a
slot ( remembering this is precision work) - that's
$300 for two rotors and then their's the welding costs.
You do the numbers.

Hey all you smart guys. Why can't the apex groves just be welded up and a
new groove cut? Welds are supposed to be as strong
as the base metal or stronger. It is not a "new" technology. EDM
machining has been recommended to cut the grooves to 3 mm so
what am I missing? Is there a better way to do it? Cheaper alternative?
Cast our own rotors? Tell me more. Talent and ideas are
not in short supply on this list.
