Have a few very tight screws on the footstrapa on my TT that I need to get undone, anyone know of a good method to get them undone?or direct me to an old thread that has any good methods??

Tried some freeze spray from Bunnings to no avail!!

Can any shops in Perth help?

Cheers

If they are salted up boiling water is the trick,just poor it on slowly bit at a time and get a paper clip in around the screws to loosen the salt and oxidiation up.

I just spray WD40 around the screw and it works a treat.

+1 for boiling water as well

Had a similar problem on my TT fins; yep agree with the WD40/CRC advice but do yourself a favour and use the correct size Phillips Screwdriver which is most likely a #3 as you'll reduce the likelihood of slippage and get more force.

Other tricks:
Put the board on something soft like a towel and with a tack hammer tap the top of the screw head with short sharp taps (light taps not thuds)

Sounds crazy but sometimes a screw will move in the tightening direction easier but if it does stop as soon as it moves as you don't want to strip the thread.

If you get any movement go back the other way and keep going back and forth - each time you should get a bit more loosening travel.

Use a hair drier to heat the screw head, ice to cool it down - do this a few times. (careful not to over heat and damage plastic or gelcoat)

On stubborn screws I use a product called Recoil Re-grip but I can't see why something like Jif wouldn't work. Put a drop in the screw head and it reduces slippage from the screw driver. (less slip more force)

Most important, be patient as it will generally loosen just keep trying and don't be heavy handed.

Add-on comment: I'm assuming the screws are stainless steel because I have seen people place steel screws in boards and wonder why the threads are rusted solid. You still might be lucky to remove steel screws but you'll need a hell of a lot more patience and a bit of luck.

^^ in addition to that, if heating use a soldering iron to heat the head, it will break down any thread locker that has been used... hair dryer or heat gun is nowhere near directional enough not will it get the screw hot enough.

Impact can help a/a.

But the WD40 soaking and correct screwdriver is first step. Push down as hard as you can with two hands and have a friend turn (minimises chance of burring the head)

If you do bugger the head, Dremel a slot in it and use a flat blade screwdriver

Boiling water, vinegar all good
impact screwdriver best
