Humm, I'm 78 Andy, & even at that, probably more time than money. What few of those covers I have seen were all well above the hundred dollar marker on this side of the pond. And I have considered making spring rollers before & wouldn't consider it much more than an exercise in making a roller holding tool to roll it around a suitably sized mandrel in the lathe. But what do you call wires? Tape measures over here on this side of the pond generally contain a flat spring (flat as opposed the the across the width curve the tape itself is given to stiffen it for a good "standout" or stickout without the tape breaking over) that is usually very close to the tapes width, in this case about 25mm. If anchored at the ends to a hub on each end, with one hub being x number of turns of the thickness bigger than the one anchoring what would be the inside, fixed post end, And anchored at each end to a non-rotating hub so that it will come 'unwound' only if its broken, then it seems like it ought to slide sideways in and out of itself regardless of any tension it exerts to unwind itself. Got my curiosity up, I'll go knock an old one apart just for S&G. Back when I've had time to fiddle with it a bit. Thanks Andy.
