Wow, so beer is good for cutting aluminum? Oh wait... I might have already known that.

Only if you're using the American horse urine excuse for beer.  Microbrews and European & Australian imports are a horse of a different color.

yrs ago when I had my mech shop we used to get a lot of cars/trucks with broken bolts in heads and gearboxes .
we use to get the mig and place a washer with the hole over the broken bolt/stud ect then put a tack weld from the broken bolt to the washer then cool it down and slowly build up the weld from broken stud to washer . once the weld cooled we then put a nut over the weld an weld it on the inside so you could get a spanner/socket on it an slowly unwind it .99percent of the time we could get the broken stud/bolt out an hardly no damage to the thread or the head/gearbox .I still do it that way on some Harleys an jap bikes I work on and have taken 1/4 unc taps that my son broke off in his alloy rocker covers he made for his car

I have used that same method for years with good results.

Beer is mostly water. By any kind I meant that apart from ethanol you can also use all the industrial kinds that are not good for consumption.

I think Vinny was being facetious. 

We are way to fond of beer around here to waste it as a tapping fluid.

Of course he was.

And I was too.

I'll have some kind of allergic reactions when consuming anything alcohol...

Anyway, I redid the part and have the pieces completed. They're all mounted on the frame of the 3D printer.

Thanks to all for the tips and how to.

I know I'm late to the party but I asked my dentist to save used dental burrs for me for this kind of thing with small taps or screws. The burrs aren't as sharp as they need to be anymore for working on teeth, but still good enough for grinding away metal.

They throw a mixture of slightly worn carbide and diamond burrs in an envelope (after they sterilize them) and give them to me when I go in for my cleanings. Gotta love a dentist that gives you free tools!

Try asking yours. Worst that could happen is they say no.
