If it's just one bolt and you're in a bit of a pickle could you not just use a hacksaw?
Look on eBay and read reviews.
Angle grinder might be your best bet but try not to cut your body parts off.
Use goggles and proper gloves.
or pay a garage to do it
A rotary multitool can be slow progress, but can also be handy for certain jobs and is a decent tool to have at on your shelf. Ive got a cheap Vonhaus one (this one) and it works well. I can also highly recommend the Dremel EZ speedclic head and cutting discs. They allow a bit of give so the discs don't snap anywhere near as easily as the standard ones do
i've been using a Lidl/Aldi dremel type tool for years and years, it was really cheap but seems to keep going. Trying to get through a bolt will take ages but for a one off it'd probably be ok.
I've used mine a couple of times to grind off nuts on the back of a turbo that were rusted solid with really bad access to other tools, just took some time and a couple of cutting disks.
Can buy a small grinder.
I have used a Dremel for car work before but really it's like using a pair of scissors to cut the lawn.
no room for a hacksaw blade .. but room for a dremmel ?No its a tie rod end, no room for hacksaw or nut splitter, I tried.
Is it green & black? That's what I've got, also from one of those two. Excellent little thing however the tools it came with were woeful so I've bought some better ones as and when needed.
@jsmoke make sure you wear eye protection. Even a Dremel's little disc runs a high chance of shattering and can blind you before you can blink.
