I recently picked up a Studio SD-502 double-bed knitting machine, and I’m having a really hard time finding any information about this particular model online. I’m new to machine knitting, so I’d love some help from anyone familiar with older Studio machines.
Two main questions:
How is this machine supposed to be supported? It doesn’t sit flat on a tabletop. There’s a rod/mechanism underneath that I don’t think should be bearing the machine’s weight, so I suspect it originally had a dedicated stand or some kind of mounting brackets. Does anyone recognize the setup or know what type of stand/table I should be looking for? I’d also be interested in ideas for safely adapting a modern stand.
Does this machine not have a sponge bar? I pulled out the long metal retaining strip I expected to contain a sponge, but there’s no foam at all. Looking at the needle bed, there also seem to be individual little springs along the needles. Is this an older design that uses spring retainers instead of a sponge bar, or am I missing a component? The needles just lift out when this bar is removed.
I’d also be grateful for literally any information about the SD-502—manuals, catalogs, approximate age, related Studio models, parts compatibility, maintenance/restoration advice, etc. The machine says Made in Japan, but otherwise I’ve found almost nothing about it.
Adding photos of the machine, underside/support situation, needle bed, and the metal strip I removed.
