Yeah Robert, I'm somewhat familiar with welding. Learned the
trade from me pop when I was just a sprout. Made my living
at it for most of my adult life between running the family's
welding fabrication shop when younger then working at a
government accelerator as an instrument welder for many years
toward the end. That's exactly why I'm concerned about the
alignment. With that large of a weldment it's orful easy to get
a slight misalignment of the two legs. Gonna have to make sure
I've got adequate adjustment designed in to the anvil mounts for
the tracking after the frame is welded. You know that, no
matter how much care and technique you put into it, it's still
gonna warp some. Only way to combat locked up weld
stress is to weld it in a jig then stress relieve it
by heat treating it. But that of course is impractical
for a large structure.
Gonna need someone to leave everything to Carl. All the one and
only daughter is interested in is politics and shoes, as is her
significant other. They're no doubt gonna have a grand two day
auction the weekend after I'm gone, then head for a warmer
climate.
I'm starting to zero in on a design for the quick release cam.
Think a lower tube from telescoping square tubing might be the
best choice. I did find, on my shelf, a handful of 3/4" acme
threaded rod, so I've also got the up down adjustment somewhat
figured out.
I guess it's about time to stop the train and get the power over
to my mill. Been putting off running the power to the other end
of the building for my machine tools because I know it's gonna
tie me up for a week or two. First I have to finish insulating
a 12 foot wall then sheeting it with steel before I can run the
electric, it's going on the outside of the sheeting. Kind of a
domino effect goin' on here at the new homestead. Can't do this
till that's done and can't do that till this is done and on and
on.
Better get to work, sun's gonna be up soon and I'll have to
crawl back into the coffin.
