I just bought a new Janome 712 T sewing machine. My plan was to put it in place of my old treadle machine. I ran into some problems of course. The bolt/ latch things are too widely spaced and too large to fit the holes in the machine. So now I'm looking for a new top to replace the antique cabinet with and the correct sized bolt/ latch things. I can use the base part of the treadle machine though. I wrote to the company that I bought the machine from to see if they have the correct size bolt/ latch things and am waiting to hear back from them.
