Hi D!
Cabinets for fiddles are going to be hard to find without the machines. Better to watch Craigslist or ebay for a set of irons, have those wonderful men that you have make a top with a cutout for the machine and holes for the belt.
In my opinion, you are NEVER too old/busy/whatever to do exactly what you want and are able to do!!
If we left these old sewing machines to the youngsters, they'd have all been melted down years ago...very few young people appreciate/enjoy these old girls.
Glad you found us and figured out how to post!
