One thing that has bugged me about my sewing machine since I got it, is it's erratic foot pedal. Sometimes its ok, sometimes I get nothing....nothing...nothing...BOoM and off it goes.
Well today I decided to give it a good clean and some oil. The first seam I did, I noticed how much quieter it was. Awesome! On the second seam though, the speed issue was worse than it ever was. I think the friction in the machine was helping control the speed, but now the pedal might as well be a switch, it's all or nothing. Unusable for me.
It's an old machine (a Frister & Rossmann Beaver 4, probably from '81) and has (I think) a rheostat in the pedal. I've had a look inside and there isn't really anything to fix. It's a very crude mechanism which allows the electricity to arc across the terminals from what I can see (and here).
Is this an issue anyone else remembers having with an older machine?
Does anyone know of there is someway of fixing or modifying it?
I can't topstitch at 900 spm
