Members Ogoki Posted October 26, 2017 Author Members Report Posted October 26, 2017 I have done so, but I generally consider the manual and its specs to be a starting point. It recommends #14 or #16 needles, but an experienced member on the site has said #18 or #20 needles are fine. My twin-needle post-bed Seiko is a very similar machine, but I notice that its tension disc springs are stiffer. I don’t see why running similar springs wouldn’t help this machine - or at least they would help me in the way of piece of mind!

Singer springs may work but the Pfaff springs are longer and have a raised tip (at least the ones I have seen) Edited October 26, 2017 by Constabulary Quote ~ Keep "OLD CAST IRON" alive - it´s worth it ~ Machines in use: - Singer 111G156 - Singer 307G2 - Singer 29K71 - Singer 212G141 - Singer 45D91 - Singer 132K6 - Singer 108W20 - Singer 51WSV2 - Singer 143W2
Members Ogoki Posted October 26, 2017 Author Members Report Posted October 26, 2017 Good eye, Constabulary! Beehive springs seem to be readily available (91-010 183-05), but the check spring (91-010 179-05) does not...
