I bought two gates at a yard sale that I'm going to mount in the garden.
Got a great old office chair that needs a little MIG welding to stabilize
the base. I went through a little 1.2 hp Gamefisher motor I got with my
used fishing boat. I'm getting some steel ready to make window awnings, and
getting the sewing machine tuned up.

What's everyone up to? So much damn political talk going on, you can't hear
the jaybirds.

I haven't done jack **** lately beyond overhauling the treadmill.

I'm confident with MIG but I stil need to address E-field issues with
TIG re my implanted cardioverter.



If MIG doesn't bother it, then TIG shouldn't, either. The electric
field from the HF won't penetrate the body, as you are essentially a bag
of salt water.

That certainly does seem reasonable, but they do have those field
specs and I'm real low on bravado here. The unit itself is just under
the skin so at least the beginning of the lead is also quite close to
the surface.

I wonder if shielding the cable might help significantly. Haven't
tried that yet. Just knowing I can get there from here seems to have
relieved some of the urgency.
