You can use grease on treadle irons, but only if you take it appart.
All the cast iron straight stitchers were flat beds. You need to fold down the legs and sort of work around the area by turning the bulk of fabric. Some people keep a freearm model for this reason, but mending pants should generally be fine on a flat bed. It has a lot to do with getting used to it, my suggestion is to persevere.
I ordered the special sew retro grease that’s supposedly specifically formulated to melt at the same temperature as the original motor grease. And yes, only the sewing machine specific oil on the machine itself. I’m sorry I wasn’t clear on that. I think I like the idea of ripping the side seam out to have full access. I like plenty of room to work. Well, now to find a seam ripper 😂 thank you all for the advice! I really appreciate everything you all have suggested. I’ll try folding the pants leg up as well. The problem is some of these tears aren’t super small. I’ll report back on my progress as soon as I get to play around with things.
