unscrewing boss pedals trouble

[loki]

has anyone had a hard time trying to unscrew the back lid from boss pedals?
i`ve had a Line selector, a DD3 delay, a SD-1, both old and new, but everytime i can`t seem to take those screws off.. it always ends up with damage on the screwdriver or the screw itself..
has it happened to you too? any suggestion?
thanks

Ok silly question here but bear with me..........

Are you using the right screwdriver?  screws arent simply cross head there are many different types and if you dont have a good set of screwdrivers you may just end up damaging the screwhead

No never from a bought pedal, hammond boxes yes definately! But years of faffing about with weathered motorbike fasteners (often made of some kind of cream cheese) has taught me to select as snug a fit screwdriver as possible, and push as much force as you can, (ie. bodyweight) into it while turning. Get it on a surface and put your entire weight into difficult ones. You can cut a groove with a hacksaw if you knacker the head and get a flat on it.

Nope, I've played around with my DS-1 numerous times and I've never had a problem with the screws.

From the factory some boss pedals are indeed a real bear to unscrew, you need the exact right fitting philips with a nice fat handle to get the leverage, and you have to bear down hard so it doesn't slip and strip the head.

yes indeed... i tried every screwdriver i could get a hold of... both flat and cross..
in the end i only managed to unscrew the top 2 screws... then just bent the lid, there was no other way...

A steel screw or bolt can get stuck inside an aluminum hole after a while, and possibly a chemical reaction where the two different metals meet has to do with it - but that's a guess. When I used to work on motorbike engines, I often used this trick : put a phillips screwdriver on the screw head (as if to unscrew it) and give the screwdriver a short blow with a light hammer. That "scares" it, as they would say in Dutch, and then it ain't stuck anymore. But with a stompbox, considering what's inside... I don't know. Maybe as a very last resort...

maybe try spraying just a tiny bit of penetrating oil, not so it goes all slopping around inside obviously but a bit might help....
