SheepyBee Posted January 29, 2016 Report Share Posted January 29, 2016 We have an U 2 , new to us (Mom in law and D in law) and we are new to L A. I have been watching this forum for several years, and gathering info before we actually bought our machine. I am not afraid of making some modifications (had to cut table in half to get it upstairs) and am considering changing to an M bobbin. It appears I need an M hook and bobbin assembly and then set timing to make the change over, is that correct and is it worth the cost? Do prewound bobbins actually increase the amount of thread by 40% vs winding the bobbins yourself? Thanks for any advice. Link to comment Share on other sites More sharing options...
