A new boiler would be cheaper than getting a couple of studs replaced on an end plate? This machine is a lever and was made in the 80's so I doubt they make boilers for it but it's beautiful and I can't just throw it out cause the bolts are rusted. There has to be a better answer. Not that I don't appreciate your input, but replace the boiler?
I'm thinking it might be difficult to even find someone who would be willing to do the work. If you do it may be more expensive than finding an espresso machine repair shop with a used serviceable boiler they would sell you. Are you saying the studs are definitely not usable at this point?
Edit-Sorry I was thinking they were welded to the end plate.
If they are studs screwed into the end plate, simply drill em in the centre and use an easy out to unscrew them. If they have broken with a ragged end, grind em flat before centre punching and drilling them. you may have to use some heat on the endplate to get them out, or perhaps you won't need to.
I believe that the bolt shown in the picture is intentionally necked like that. It is a one-time use bolt designed to give a little with the expansion of metal when torqued to the correct spec.
The heater studs are most likely bolts braized in place (With the head on the inside of the boiler) to leave the studs exposed. If they break off you'll want to carefully torch them out and braize in replacements. Paying someone to do it for you would probably cost something more than a new boiler, but new boilers aren't always available.
