Husky, Most of the older machines have a top tension knob/spring that can be adjusted for even more tension. On some of these older machines the springs have taken a set and are effectively looser than they were 50yrs ago when new. Think of it like the top turret on your rifle scope after you switch loads and you re-zero, of course your going to have to re-set the turret to the 0 mark. Same with the top tension knob. Once you make the proper adjustments to the spring and are happy, loosen the set screw or jam nut and reset the knob to middle range and lock it down.I'm basing my thoughts on the bigger is better premise. My settings are maxed out yet I'm still having issues. If I back off of the thread tension, I get a rats nest under the fabric. So, I'm thinking a bigger old plain jane singer should work.
Those Sailrite machines look nice.
Or maybe set it to 9 for upholstery thread and double check that 0-1 is ok for thin UV stable polyester thread for silnylon work.
The good news is with these old cheap used machines, you can have two machines set up for different threads and weight of material. I hate fiddling w/ machines and switching threads, so I don't.
