I have (sort of) Beaten the Four Fastenters of The Appocolypse!

A nd welded cast iron :)

this played an important role in the defeat of the Four

I bought a cobalt-steel bit and had to sharpen it eight times to get through the bastards. Then I still had to ream them out with the hammer drill to break the heads off.

now I’m stuck with this :/ the studs stick through a little bit on the other side... I don’t know if I can get a good enough grip on them with the Giant Vice Grips to get them out... for now they are soaking in 50/50 acetone/atf overnight in hopes that that helps.

this is a different carrier that cracked while removing the bearing from it...

MuggyWeld 77 does indeed work like gang-busters on cast iron!

i’ll be damned, that looks like a strong weld. excellent penetration!

satisfactory,

Now you need to find bolts that tough sold anywhere currently.  I dare ya.

My guess is, IF i could find any, they'd be ~$10 each.

if/when you finally get tired of fighting with the vice grips and the bare stud...... get a nut that just fits over the stud, and weld it on(a good weld, not just some tack) . while its still warm, put a wrench on it, and just back it out.......

too easy?.......

I’m not sure I can get the thread engaged, the back side is curved... but I may give it a shot. I had bad luck welding nuts to the heads, they kept breaking off at the weld. maybe try something other than 7014?

hmmm, looks like I should give the 1/16" 6013 a shot, I burned through a grade- 8 with 3/32" 7014, and when I turned it down to 60 amps I had shit penetration and the nut just broke loose every time.

i have had a few stobs that were hard to get out over the years. had one on an intake that i needed to go back to the hardware store to find more nuts. i was welding to an innie by the time it came out. most stuff will come out with ease by comparison. just get some decent penetration, give it a minute to transfer some of its heat, and then just put a wrench on it. they usually dont put up too much of a fight..... as far as the weld goes i like 6011, or 6013. i am usually using 1/8 and smaller. and that is on an older lincoln crackle box red tombstone looking welder. i would look at around somewhere less than 90 prob around 75

something about like this.....

will burn just about everything that i need. when i need to weld small thin sheetmetal, i go to tractor supply, or northern, and hunt down some 1/16 rods.........

i like the 6013, for its slightly higher flux, for puddling, so i use it to glue my stuff together, and if it something that i am going to be mean with, i go over with 7018.......

but for that stob, 6011, or 6013, at 1/8-ish.......

I have a cheap (but so far, very good) DC inverter welder. It maxes out at 160amps, but I can dial it all the way back to 20 amps and have successfully welded 16ga sheet with it using the 1/16" 6013. I think that’s what I‘ll try tomorrow, get some penetration without blowing it away. I think I hav e some 3/32" 6011 kicking around too...

a nickel alloy rod designed for joining dissi milar metals should do the trick. however turn the heat up a tad and keep that tip of the rod buried at the bottom until you think its going to melt the nut. this will force the flux to float up. otherwise the flux can fill the outer part of your puddle and you won’t get a good join between the stud and the nut. and stir that puddle a little as you go to force the weld metal out to the nut

any flat head bolt of this type is made of hard alloy to keep the hex hole from losing it’s shape. most ace hardware stores should carry these and not too expensive. i would use anti seize compound on the threads in case you ever need to take it apart again

My bottle of anti-seize will definitely get a work out on this reassembly.
