avimeso Report post Posted April 15, 2013 Hi i handsew leather with 0.8mm poly waxed hand sewing thread. Was after a machine thread that will look pretty similar. Would that be a 8 or a 12? Also would i be better with 200/25 or 230/26? Machine is a adler 205-6 and will only be used to sew leather. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted April 15, 2013 (edited) 1 mm thread is about #554. 0.8 would be close to #415. Use a #26 or #27 leather point needle with your 0.8 mm waxed thread, Run it through silicon lube on top of the machine to help it feed through the tensioners and guides. You may have to move the hook to avoid it hitting the needle. Some Adlers use spacers between the shuttle and its housing to properly space the hook from the needle. You can buy them to match the size of the needle, for about 6 USD. Since they are marked in metric, you'd want a #230 spacer for a #27 needle. The machines usually ship with a #200 (#25 Singer) spacer. Buy lots of #27 needles. They come in handy for securing porch boards that lift after the Winter. ;-) Edited April 15, 2013 by Wizcrafts Quote Share this post Link to post Share on other sites
