RMweb Gold Ralf Posted January 11, 2020 RMweb Gold Share Posted January 11, 2020 Hi Folks, Getting back into modelling and using 3mm / Finescale Sprat & Winkle couplings and have a couple of questions... - Why do they use both 26swg Nickel Silver Wire and 28swg Brass Wire?? Going to buy some straight wire to make staples but surely 1 type of wire would do? - Planning on making a jig to improve consistency like this one (see link) - any thoughts / feedback / tips on jigs... https://cpineroad.blogspot.com/2017/03/sprat-winkle-coupling-jig.html and presumably also need a fitted height checker like the one Phil Parker has here: http://philsworkbench.blogspot.com/2019/03/fitting-sprat-winkle-couplings.html Many thanks Ralf Link to post Share on other sites More sharing options...

To answer your two specific questions: 1. the two sizes have different purposes. The loop for mounting the hook is robust, the loop for coupling is as fine as can be usable for reducing the visible intrusiveness. I use 0.45 mm and 0.33 mm straight brass wire, respectively. 2. for making the loops of a consistent size, I've etched holes onto the edge of the fret of mounts. That means they are always consistent in size. For the final fine tuning of the height, I also use a gauge based on a buffer stop. On both these points, you'll find a more full explanation in the attached file of instructions. I hope they are comprehensive enough to answer your questions, as I view good instructions as a right and not a privilege from kit manufacturers. The two photos show the finished articles, ready for fitting to a vehicle. Cheers Paul Willis Mounting plate for Sprat.pdf 2 1 Link to post Share on other sites More sharing options...
