In my opinion.........
only welding - to repair the hole where the bushings mount.
epoxy can not begin to hold. There's a lot of force going on that hole.
I'd probably weld a plate on one side. Not too thick, eight inch is too
thick I think,
about half that.
weld on a plate with the right inside diameter,
then fill in where the two holes meet, the new correct size one- leave that
as is, and fill in the original material to the right size hole.
then grind and file to the correct dimensions.
I use a tapered bit ......cone shaped thing, and put it on a die
grinder..........my Makita one does up to 14,000 rpm.....
little pointy cone shaped hardened steel cutting bit........works great.
this group is FOR asking questions, so don't hold back !~
the rod...........I had one that was pretty trashed up .......
that part I wouldn't weld on .....
I put on a good used one.
( but the body part...........repair that very solidly.
if using arc welding rod.......
what I use, and it only works well with a DC arc welder.....
is 7014
and 7018.
'7014' is described as 'smooth fast easy '.......and it is. the arc is
harder to get started than with 6011 and 6013........but it makes a very
nice weld.
7018..........the '70' means 70,000 lbs tensile strength I believe.......
I use that for things I absolutely never want to see come apart.
I usually tack things in 7014, and finish weld them in 7018. )
, or use wire feed.
