Flattracker Report post Posted April 5, 2014 Hi, (just remembered that paragraph button!) The walking foot machine I'm looking at currently takes about a max of Uk #15 thread which I think is somewhere between a US 138/207. I'd like to take some #15 thread to the shop to try it on the machine, they don't have any. A quick google hasn't shown any obvious suppliers either. I get a fair amount of my hand stitched stuff from a local place and Abbey England. Don't think the local place does much stuff for machines & Abbey have what they call ticket 20 and higher numbers (thinner thread). Question is having never bought thread for a machine, where can I go to get a proper good quality thread at that weight or is it a rare thing in the UK? Is there any real difference between a 20 & 15 thread? Cheers all Quote Share this post Link to post Share on other sites
Anne Bonnys Locker Report post Posted April 6, 2014 Unless it is a 132k/253 style machine there is little chance of it handling anything heavier than 138 thread. A standard bobbin case simply is not designed to take anything heavier and there are issues with the take up spring and tension on the top end. For M15 thread look for a supplier of Amann Serafil I suspect the dealer is overstating the capacity of his machine. Generally to take anything heavier than M20 you need an open frame shuttle Quote Share this post Link to post Share on other sites
