I have my Mother's tread machine that I learned to sew, but it is real rough! Been in the basement in Michigan for 20 years or more. In the 60's my Dad removed the sewing machine and re-purposed the base to hold his lathe. So the top is cut (badly) with a hole so that the sewing machine will go there, but with this raggedly hole on the left end. It is in my garage and I can't decide whether to replace the top piece, or just what. Would appreciate input!
