My vote would be to braze it. OA and bronze would suffice.
Clean ,vee, fit up tight, use slightly carbarizing flame, heat rod,
dip into flux and have a go.

Ive been tasked with repairing a motor end bell. The bell is a C face,
with only 3 bolts on the face flange..and it was dropped, breaking off 2
of the three mounting flanges. Material thickness is no more than 1/8"
(a very poorly designed endbell). Fitup at this point is good, but Ive
minimal room to work as the broken sections are thin in cross section as
well.

Ive got
good quality 55% silver solder
3/32" Ny55 filler for tig
1/8" Phos-Bronze filler for tig,
.035 SS wire (mig wire)
suitible fluxes for silver solder
suitible fluxes for cast iron brazing
Bazooka bubblegum
Bailing wire
JB Weld
Duct tape

Tools:

O/A rig
300 amp squarewave Tig welder


What is the best method to effect this repair?

Ive only got one shot at it and Ive got to deliver it Monday. I knew it
was going to be tough..but didnt realize just how thin the motor bell
really was...sigh...shrug.

There is really not enough material to drill and pin, unless I use
paperclips for pin material....its that thin.

flanges will carrying some twisting torque and will be carrying motor
body weight. Motor shaft is deeply buried in right angle drive unit so
will be fairly well secured from too much weight/torque.

Of course Ill prep by sand blasting/bead blasting the broken bits and
the end bell breaks.

Thanks for any advice. Good advise preferred, but bad is also welcomed.
Then other posters can pick on you. <G>
