Thanks for the replies. Everything seams to be in good shape ( clearances , timing ) as I use the wheel only to hand sew it all works perfectly but when I put on the gas no matter how slow I go it cuts it as its rolling thru the shuttle/bobbin assembly. I wonder if replaced the shuttle and related parts if that would fix it? Or should I just have it rebuilt. It came out of the old bona Allen saddle factory after it burned down .

I have a old Randall and I am needing some advise on this beast. It keeps cutting my top thread as it rolls over the bobbin ? About to pull my hair out!
