F4 BLT stuck/rounded bolt removal

[chicken]

I’ve recently acquired an AMP Research B4 with an F4 BLT fork and noticed that some of the o-rings that protect the bearings are perished. I’ve ordered those but the next problem is getting out the rounded bolt heads in order to replace them.

These bolts are like butter and there are titanium replacements available. I just need to get them out so I can replace the o-rings and install new bolts so the fork is serviceable in the future. A couple are functioning but the rest are beyond help.

Given that I have no proper equipment/skills or a work bench, just wondering if there are any retrobikers in the Heathfield/Hailsham/Hastings (all the Hs!) area that have the gear and expertise and who might be able to help me with my quest in getting the bolts out? Just need to make sure the threads within the linkages are preserved for prosperity.

Beers and snacks and a semi-able assistant (moi) will be supplied.

Cheers,

Tom

In the same circumstances I have bought Torx bits, taken a file to the ridges and tapered the ends a little.
Then hammer into the Allen head and remove with a socket spanner with the correct drive adaptor or a locked electric drill.
You need to keep pushing the bit in as you turn.

Obviously adding a little Plus-Gas an hour beforehand to the bolt to maximise your chances of it not being seized helps too.

Yeah. I’ve been in similar situations and tried the above without much success. Just a bit unwilling to go down that road again as it never ends well. I’m probably in the wrong hobby in fairness . Simple mechanics like servicing I can do, but this is a little specialist and just want to achieve a good end result so I can do it justice.
