Hi Andy:
I'm real safe from $1600 tools for quite a while.
This really isn't engraving, i'm not sure what to call it...hot chasing?
I have untold hours in the shaped chisels,chasing tools, stamps and
punches i use..there must be a couple of hundred by now,, maybe more.
The ones with a larger surface area take several hard blows with my
hefty TH to sink in hot bronze.
As everybody says, my methodology needs a major change if i want to keep
the surface features crisp. I only do these batches about once a year,
so i'll have time to experiment and ruminate on it. Skipped the
corkscrews this year..don't have the patience to fuss with them.
As my essential tremor gets worse, i have to change how i approach
work..engraving becomes less of an option..
