I just bought a new bobbin case and hook for juju 1508 cause mine tension spring was a messed up I was wondering about converting to a side load style like the 1541 that I read about. Does anyone no the machine that the parts come from to switch it Over and part numbers and also how do I sent bobbin tension correctly I have played around a lot and seen all the Videos of how it should be just loose enough to fall when not supported but mine is all the way loose and still to tight it seems. Is that tension I mentioned only for light fabrics. Cause like I said both mi e r tight enough to support the weight of bobbin with the screw backed all the way out. And how do I know when it’s right. Also I have been having to tighten my top tension almost all the way to even it out. Also is there any I stuctions to set up the take up spring cause I can’t find anything On that online or in the manual. Thanks
