This is a late answer to an earlier post. A fellow member had asked how to replace a worn brush on an early curved needle machine. Remove the old brush and find a artist paint brush the closest in size you can find. Remove the wooden handle from the "tin" section also holding the bristles in. Next, squeeze the tin section in a vice or such to ensure the bristles are held in tight and then cut off any extra tin section you don't need with tin snips or hack saw making it close to the same size as the original one. Then you can trim the bristles with scissors to fit. Remember the ends of the bristles just touch the rotating hook and never press tightly against it. ?
