Hi PekkaNF

>>Main thing is not too loose cool and swear profusely and slip the mallet out of sweaty hands trough the wall, hedge, and BMW next door.

Was that from personal experience ?? :lol:

Had a screwdriver and then a crowbar under one end. Jumped on crowbar but apart from a few cracking noises nothing gave. Then spent about 20 mins hitting the crowbar with a lump hammer trying to get it out. Alas no longer have my chainsaw which would be the best tool by far. I have another older crowbar which has the curled end broken off. Will try that with some scaffolding pipe as leveridge. From earlier result it just seems to crush the wood fibres in contact with the crowbar but the actual piece of wood does not seem to move. I generally favour brute force on this kind of thing because even if it doesn't work out as planned it will normally change things enough to allow an alternate solution to work.

Kind of reminds me of the three men in a boat (Jerome K Jerome) trying to open a tin of pineapple:

about 3/4 way down.

Will get serious with more brute force.

Many thanks

now don't take this to heart

but if hitting it with a hammer won't do it you need a bigger hammer ,if that don't do it hammer is still not big enough when you get to a 28 pound sledge and it still won't move , call in Blaster Bates he should shift it , but it may be still there and the workshop may be gone. :doh: :doh:

a decent crow bar would do it
a mix of saltpetre sulphur and charcoal packed round it apply a ignition source , opps that would be a bit dodgy

So I weakened an area across the width by chain drilling 22mm holes either side of the screw, hammered my trusty Wickes screwdriver in the end, then hammered in crowbar with 8lb hammer. So I hear this ringing, going higher and higher in pitch every time I hit it, but I'm in the groove with this thing and carry on. Then plinck, and its all over. the screw has given up, and my closely drilled holes, weakening the wood are still perfectly intact :hammer: . I'm not sure what this wood is, but its pretty darn tough. Still now I have the methodology its should be a slam dunk.

Thanks for the good advice (basically hit it harder)

Best Regards

Drill holes close to and around the screws. Pour some sulphuric acid in and leave it to work on the screws. Neutralise with something suitable, clean up the area, drill the holes deeper into the wood to expose more metal and treat with acid again. Repeat until you get it has dissolved away completely.

Keep the area well ventilated and have something suitable to neutralise the acid handy in.case of an emergency. You could even try hooking it up to a battery and making the screw a sacrificial anode if working with acid doesn't appeal.

Edit:
I didn't realise you had already got it sorted. Brute force always wins.
