hold your work while you weld. This Instructable goes over how I made
my third hands: welding fixtures.
Thanks goes out to schip666's Instructable
for giving me some basic ideas on how to fabricate my fixture.
I tried to simplify my design as well as make it versatile and capable
of clamping objects at any angle.
Things I used:
weldable steel rod
nuts and bolts
and of course...
TechShop San Jose =)
Step 1: Prep the Materials
two third hands and needed two joints for each one. Each joint needs two tube
segments, and each third hand needed two joints for a total of 8 tube segments.
I then used the drill press to cut a single hole into each tube, large enough
for the bolts to fit through.
The weldable rod I cut into two longer pieces for the main stem of each third
hand. I also used the bench grinder to put a bit of a beveled edge on the rods
so I had room to fill when welding. Then I cut four slightly shorter rods as
the adjustable arms.
Cut my steel plate to make two nice little bases.
Cut some smaller steel rod to about 2" semgents, to be used later for making
wings on the bolts.
Using the SandBlaster, I removed some of the coating on the C-clamps to make
sure I got a good connection when welding those later.
