Seasons best wishes to all. Hope its been an enjoyable one and alls warm and safe for you all. Over here in New Zealand (it's mid summer 27 degrees C here (approx 80F)) we go to the beach or lakes for most of the next month or two. Bit different for a Christmas for you Northern hemisphere bods ay! :cool2
The problem I have, is with an old single banger diesel (UK Bamford) I have and which I have a broken stud in the crank case and have started drilling it out after 1st centre punching it. The pilot holes drill bit was HSS of only 3mm in size but when it got to the end of the 3/8 stud, it grabbed and I must have not been ready for it and it either must have moved the drill & bent it or for some reason, it broke.
The stud broke below the surface line.
Does anyone got a bright idea how I might get either this drill bit out or the whole 3/8 stud out?
I'd rather not use heat because of the paint work but there may be no other way.
I have considered either carefully drilling a number of other 3mm or 2.5mm holes around the centre drill bit but it scares me that I might break them also and really stuff it up even more! Also considered is getting the Dremel out and slowly grinding away at it. I have an "Ezy-out" but the broken end of the dill bit is too close to the surface to allow it to get a decent bite at the seized stud.
Any suggestions would be greatly appreciated.
