Now that I am retired (!) it's probably about time to get around to doing something with this (these!) machine(s).

Enough with the brackets. In the intervening years, has a known good, simple conversion for this machine become available?

I have the funds now and an infinite amount of time. I really ought to crack on and get this done. I have both the Boxford and Denfold machines just sitting there waiting and gently rusting.
