well done getting it out.
I have to say that I do weld nuts and bolts to snapped or head damaged items on a regular basis.
Works every time cos the heat from the welding usually losens the item.
The earthing of the welding isn't an issue if you hold what you are welding on in a mole grip with the earth lead attached to the mole grip.
And as for welding to the surrounding rather than the object that happens if you use the wrong nut or bolt. In your case if a correct size nut had been put over the end of it and filled the centre up with weld it would have been ok.
Well done drilling it though, but I had to just stick my 2 pennorth worth in cos I really do reckon welding to be a good solution/trick.

Now though im an oil pump bolt short, has anyone got a spare set as the threads on the other 2 are a bit ropey??
I find Bredy's the local agricultural place useful for imperial fasteners. In fact, today was the first day they let me down, when they didn't have a non-existant 11/16 UNF hydraulic fitting (they may not exist, but Rover still used them on late Minis...). If you're in a hurry and have something like that close by it might be worth a trip? On average bolts cost me around 7p each, and I do go in wanting only three or four at a time halfway through a job!

But in this instance the bolt had been bottomed out and snapped when being removed so i personally think that drilling and re-tapping was the only option.

so do I. And I said well done.
My point was that welding is a very good solution and I felt it needed saying because the general consesus seemed neg towards welding of snapped and damaged fittings.
I weild spanners all day for a living and use the technique at least once a week to almost 100% success.

I was not having a go at you about it!
I have used the technique myself in the past with sucess
And just for the record, i too wield spanners all day for a living.
Anyhow, Youngun, PM me your details as i have a set of oil pump bolts here for you.

It may be teaching my Granny to suck eggs, but make sure the holes are clear before you use your new bolts. I have had oil in blind holes cause a problem in the past.

Got myself out of big trouble this evening after rounding off a bolt in a rare BMW engine, blast of the mig and there's a nut on the end! I still can't believe how long I hesitated about buying one, it's more than paid for itself.
