  • Stuck ALU blanking bolt in the threads of an aluminium frame... Screw removers didn't work as ALU is very "soft" so the screw out bit just made a bigger hole...

    ...all blanking bolts are aluminum. Against steel threads. Hi, breaking & alusteel marriages. Really not ideal I'll put plastic ones on now, ugly but safe.

    So it's been drilled and now the pain of removing the last bits starts. I don't dare to use oven cleaner as it's an ALU frame.

    Is there anything to speed the removal of what's left up? Or it's hours of "fun" with a Dremel the only way?

  • Thread a tap down the bolt hole to chase the thread once you've drilled out everything except the thread of the seized bolt.

  • It's a good idea to chase it anyway after all this, I'll order a tap. More grinding to do before I get it down to that...

    Tx :)
