Another idea Army,
a thin open ended wrench may slide in there, then hold it close to the slot with an adjustable.

A small piece of plow disk or the hard edge of a plow blade would also work.

Thank you all very much for the suggestions - yesterday was a bad hair day - it started off with a puncture on the bakfiets (direct translation from Dutch => box bike) which meant I had to walk the children to school in the rain... I then struggled with the puncture the whole morning... pathetic!

So a stubborn fastener was more than a match for my bad mood. After lots of (non alcoholic) beer and chocolate last night I'm refreshed and ready to get my ducks lined up!

Don't leave that there - I'll take it to bits!

Done it - I got some help from #1 son (5 years old) and we got it out!



The trick was to first remove as much corrosion and crud from the edge of the screw head.

I ended up taking off small amounts of metal - not that you'll see it though.

I'm glad I didn't get too rough with this bit - it looks expensive:-

Good Show! What did you use to turn it?

A little late, but for reassembly, do a search for a dzus screwdriver.

http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=6361&group_ID=688&store=snapon-store&dir=catalog

Shown is a Snap-on brand, but there are others.

We used to use the "snoopy" tool to seal fasteners on the travel pods on planes. The tool looks sort of like Snoopy's head.

We want to see the tool you used to undo it Army !!!!

I'll stage a photograph tomorrow - it was just a bit of soft steel flat in the end clamped to a table and #1 son on the end of an adjustable positioned as close to the nut as possible whilst #1 dad simply twisted the whole tail cone section and it came undone.

I think the key to success was probably to do with the scraping away of the corrosion around the nut.

I can't believe I've forgotten about dzus fasteners - I used to work on aircraft - thanks for the tip.

Any Zizzer-zazzer-zuzz would have suggested dzus is the perfect tool for the job, as you can plainly see!
