Progress update:

Arr yes, copy on the fuck fuckitty, what seems to be the cause of the fuck fuckitty? Where you at?

Gee, a 3/8” bolt shouldn’t snap under the weight of someone’s foot, even if they were grade 4.6 bolts.

Since getting a TIG, its been my go-to for removing every snapped, sheered and seized bolt.

Well I got an Easyout with lefthanded bits and managed to break the drill in the bottom of the first hole.  Got the bit out but the easyout is not denting things at all in the first hole.  Have not started on the second yet other than a light pilot hole but am inclined to take the bike to the Thread Doctor in town and just have him do the job.

Bud you got to try and keep the hole in the middle, drill right through the bolt, take the hole out to about 3/16, get a punch on it and belt it with a hammer, I would soak it in penetrant of whatever flavour you have and give it a try with the easyout, if it don't come try the heat from a powerful soldering iron and more penetrant, bit more tapping with the hammer and punch thrown in, failing that weld a bolt on but be warned, once you weld the bolt will get get harder and be way harder to drill if you have to end up trying to drill most of it out to re-tap the hole.

Cheers,

clearly those bolts are seized pretty tight so wasting money on a left hand drill bit wont really help , any old bit will do so long as can drill the steel , if it is a stainless bolt i would imagine the corrosion that happens between it and carbon steel  is not helping .. if its high tensile then both are a pain in arse to drill anyway ... but in my experience dont stress to much about being exactly in the middle just as long as u dont drift to one side and gore op the threads .. and if u do happen to get through with a bit make sure u make hole as big as u can so less chance of the easy out breaking or ur really fkd ... i been dealing with these for donkeys years and what i normally do is heat the remaining thread so its glowing red then let it cool .. that makes it shrink just enough to get it moving ... so if u know a plumber with an oxy set and a small braizing head that may be a last resort , ya can soon chuck a bit of black paint on afterwards : )

agree wello,once a hole is all the way through it wont take much heat to get it cheery red,make sure you cover anything on the other side of the hole as the heat coming through will befocussed in to  a small area and will heat things pretty quick.if you can cool it quick [ quelch it ] with water it should move easy or just let it cool natural [ cold to touch] and give a hit with a punch and be on your way to finish your repair,no 2 broken bolts will ever be the same in ease/difficulty in removing.good luck and stay positive, you will win the end.
