Air Hammer

[Tom Servinsky]

Jeannie,
The blueprint, I'm sure is not that necessary, as any one with shop
experience can figure this out.  It's not rocket science..granted.
However, my schedule is hectic as it is and I'm finding less and less time
to set aside to fabricate this item.  I was planning on going to one of my
favorite machinists and have him configure it properly.  I would like the
tip to work perfect without having to fuss to much.
As my Score adviser lectured me on....concentrate on the things to you do
well and find others to fill in the gaps where you are weaker.   I'm not a
great fabricator, thus  finding the perfect blueprint and handing it over to
a good machinist makes perfectly good sense ( and cents) to me.
Tom Servinsky, RPT
