Thanks for those pointers, Jason.
Though I could honnestly say I'm all thumbs and have the general DIY knowhow of a common soldier ant, I think I can see how this would work. I don't have any penetrating oil. Would silicone or teflon lube do the job? Things like the nuts and screws and the copper grease (I had to look that one up, but I can see what that's useful for, aye) or things I'll deffinately need to go out and buy.
I've send a mail to Pro-jump, so I'll await their answer before cutting the strap, but I wonder: when I cut the strap, won't that plastic washer thing be in the way? Or would it be enough for my pliers to get a good grip?
Again: thanks for the tips, Jason. I'm not good with power tools and avoid those at any cost
Neither did I relish in the thought of finding someone who could have helped me drill those pesky screws out.
I can see that your Ingenious award is well deserved and for that I salute you.
