Well, I finally spent time on my 301a last night. I had to order a tensioner because the springs were DOA and one of the discs had a dent. My DH replaced the unit for me, we crossed our fingers and threaded it up, and it worked perfect!!! YAY!! She sews sooo straight...I have NEVER seen a seam this straight!! AWESOME!!! I also got her new rubber feet for the bottom, and I had to dig out the old rubber ones which had fossilized!!! LOL Now she looks so cute standing on her new black shoes, all shined up!!
