ICE have recommended a screw extractor, so I'll try and get/borrow one of those.

This is an extremely rare occurrence. So rare we cannot remember it happening before.


They also offered to sort me out if the frame really dies (although I suspect that however deep their discount the terracycle idler clamp would be better value)

Yes, the reviews are a bit mixed, and I suspect that stainless is going to be on the harder end of bolts to extract this way.

My next door neighbour does a lot of car rebuilding, so I'll see if he has a decent set...

I did remember right, it was 3 years ago.
The thread about another sheared bolt is over on YACF -> https://yacf.co.uk/forum/index.php?topic=54692.0
Hope this helps ....... :D
Edit:- just read the full thread and I don't think it will ........... :cry:

Just read that other forum thread and it seems we should just look at it periodically? Not sure if we would see anything though. Interesting 4 wheel trailer - is a trailer tent do you think?

It's a Camp-Rite Midget Bushtrekka Bicycle Camper Trailer.
I think its main downside, apart from it's small wheels, is it weighs 25.4 Kg which is double the weight of my trailer and separate tent.

My brother has snapped that bolt and also lost that bolt. When he snapped it the first time he didn't realize what had happened (he's thick as two short planks) and ended up sawing into the frame. No matter what I tried I couldn't get the bolt out. I took it to ICE, they got it out and patched the frame. He also started sawing through the handle bars.

If your brother ever sells that trike I will be so not tempted to buy it.

Was wondering how it was going, got it out yet?

Was also wondering, if it has happened a few times to various people, if there was a proactive way of avoiding it? Replacing the original with a tougher bolt? I guess though that could make it even harder to remove should that break and ICE perhaps less inclined to help.

It shouldn't snap. I suppose regular removal and greasing would make it easier to remove in the worst case.

Maybe use a lathe to put a very narrow hole all the way down the centre of the bolt, so you don't need to centre punch a snapped bolt (notoriously difficult due to the asymmetry of threads where the bolt has snapped)

I'll be off to a workshop this Saturday - even the SnapOn bolt removers cant get a grip on the stainless steel - at least not enough to get it turning. Even gripping the extractor and applying counter clockwise torque whilst repeatedly tapping the extractor with a hammer hasn't worked - it gets a good grip, but never enough to start the bolt moving when I eventually switch to a socket set (any handle type)

I would have got the welding set out on this job by now.

Nothing beats the local thermal shock of welding onto the end of sheared bolt, and once you have done that, you have something to swing on, so it is all good!

I wonder why it broke in the first place?

cheers

Done it!

Had an old friend over today with various tools. Managed to get a bit more material out, then tap a thread into the remainder.

I shall do the rest of the reassembly tomorrow, but phew!

Nice one! I hope the rest goes well.

That must be a weight off your mind.
