I have recently picked up a Tecoway clone to a Singer 128 vibrating shuttle. My question is the needles that came with it are 1 and 3/4" long and of course very hard to find so would like to lower the needle bar to accompany the regular 1 and 1/2 inch long needles. Has anyone done this and should I attempt to do this. I think it should be possible as long as I get the timing right. To me it would make more sense to lower the bar than to try find the longer needles. I tried to just stick a needle in and pinch it in with the needle bar clamp but I couldn't get it low enough. Any thoughts on this greatly appreciated.
