So I picked up this baby for $30 dollars at a local value village when I thought my Kenmore had bitten the dust. Turns out I was just using a shoddy bobbin with a but on it the was almost invisible to the baked eye. So I found an old rusty one that worked perfectly. Lately I've sewn a bit of leather on my Kenmore but I'm worried I might tire the motor. So I. My online searching for a leather sewing machine I remembered I had a couple of old spares laying around that could possible do the trick. So my dilemma now is I don't know if I should be sewing leather on my imperial, or how to tell if its heavy duty enough... I can tell you right now, its heavy!!!! I'll try to attach a photo of the machine, basically I am trying to figure out the model number so I can research more information... I will likely be sewing some leather chaps if this is a go!
