I used the same holes in the thread beam and the cloth beam. The canvases had to be slightly stretched in order for the holes to realign. The fabric tacks I used were 5/8″ long which are substantially longer than the original nails. I used a small brass hammer to avoid damaging the wood on the beams. With tension the fabric will stretch out once again. I ordered an additional 1/4″ metal rod as the loom is short by one…47″ long.
