Hi Folks,
I've been following this conversation with some interest as I too am in Australia (Adelaide) and have a 42-5 head 'under the bench'. I bought it as a bare 'head' for a few dollars to rescue it from a fellow who was cutting machines up to make tractors! Had no real idea what it was initially and knew nothing about the 'jump foot' mechanism until I started reading about it on-line. Wizcrafts explanation above makes it very clear! I too have been pining for an older walking foot or compound feed machine. However funds are limited and of course such machines tend to be far more expensive in Australia than they are in the USA.
Now I've managed to get through some of the bigger overdue house maintenance jobs, my attention is turning to that large lump of iron under the bench and wondering again what it'll take to get it going again. I have a suitable steel table and a servo motor is an easy find. The machine appears to have a slightly bent needbar and I'm hoping I'll be able to take it out and tweak it straight (or maybe replace it even). I guess I'm curious to know how adequate others may have found the 42-5 for general canvas work with the occasional addition of some 'functional' leather trim (reinforcement, binding protection etc)?
I've been contemplating a 132K as well but as noted, they are not cheap! I had understood them to have a proper walking-foot, but if they only have a jump foot, they maybe no real advantage over my 42-5 (apart perhaps from reverse)? There's a 31K47 available locally as well but if that too has the jump foot mechanism, maybe - again - no real advantage...
I'm also very curious to know when Singer first introduced the true top-feed mechanism? Were the early cylinder-arm machines such as the Model 17-8/10 (described by ISMACS as having 'alternating pressers') top-feed or did they have a jump foot too? I have a very nice1929 15K28 'industrial' machine (I think 'artisan' is the better descriptor) and have often wondered if the closely related 15-28 - also described by ISMACS as having 'alternating pressers' - was simply a jump-foot machine?
Any insights and advice much appreciated!
Sam
ps; and in these difficult times, may your houses not fall down around you as mine appears intent on doing!
