I am looking to getting an industrial machine. The main purpose of this machine is to make boat tops. Nothing heavier at the moment but not ruling it out. I have a line on a Singer 211G-156. The machine has had a 750W servo motor added as an upgrade. The one problem with the machine is that he states that it needs "hook fine tune". He says "looped bottom thread build-up. Might be because of improper top thread tension. Thread tensioner might cost me $100.00." I have read the tread on the identical issue on another thread and have some ideas about where to start. This machine is selling for $600.00. Is it a good enough price to risk the unknown repair costs. How hard is it to find the tensioner if it is in need of replacement? Where I live there is no repair facilities. Its $200.00 travel costs to get to the sellers location to start with. There is a repair facility where the seller lives but having to stay overnight or return for repairs could get costly. Is this a good deal or should I pass. I am an industrial electrician by trade and very mechanically inclined. If I can find diagrams and setup procedures I am confident I could figure it out myself. Is this too much machine for my needs, should I be looking for a Sailrite clone or equivalent? Thanks in advance for your valued opinions.
