Thanks for the info Jimi, stitches look great to me.

I'm amazed at how clean and bright the metal is on your K25. What's the part number of the material guide you're using?

Thanks Jimi

Thanks Jimi. A material guide is on my want list. Hopefully I'll come across one somewhere on the planet.

It's been difficult to restore this noble old machine, particularly since it's my first Singer.. Those of you who restore the older machines know exactly how tuff it is to find parts.

I just posted a bunch of Singer and Adler parts that I acquired in the Marketplace (used) forum in hopes of swapping them for 45K25 parts. Would you please take a look and see if I have anything you need or you have something I need. Perhaps you know of someone else who may need or have parts to trade or sell. I'm particularly anxious to find the Singer Oil Box, p/n 91797, .

Thank you very much. Any assistance or leads you can offer will be greatly appreciated.

Thanks Jimi, I appreciate your thinking of me. I'll contact the seller immediately.

My most urgent need now is the Singer 91797 Oil Box. That's been eluding me.

Check you PM for something you and I discussed, you may find it interesting.

Best regards

This fine old machine is gradually beginning to make some sense, recall I'm new to sewing machines. At this point in the restoration, I would like to understand the theory and the relationship of the presser foot, the roller presser and the pressure adjustment on the presser bar.

I've set the direction of the presser foot (with the roller up), so the material feeds straight by itself, with the least amount of pressure on the foot and without marking the leather. Is that much correct?

So, how does the roller work? Should the direction the wheel rolls be straight forward or angled? I've tried different directions and pressures, but can't seem to get the foot and roller together to feed straight without being guided. Yes, I know, the material is normally guided, and maybe the roller is supposed to turn the material, I don't know. That's why I want to understand what's going on with it all and how to adjust it the best I can. If there were some surviving setup instructions for these old machines, that I could lay my hands on, I wouldn't be asking all of these questions.

Thank you for putting up with them, and thank you for sharing your insight.

I´m not exactly sure what you mean. You of course have to guide the material no matter which foot is installed.

What means "with the roller up" - have you installed roller foot + regular presser foot together?

This machine had previously been used to repair athletic equipment......football pads, helmets and such. When I bought it recently, the roller presser and the right hand presser foot were both attached. That's all that came with it, no other parts or instructions. You'll note that particular feed dog has two rows of teeth with the roller being over the left row and the presser foot over the right row. That made sense and I assumed that setup was correct. I didn't know differently, so that's how I've been adjusting/restoring the machine. Image 3201shows the roller rotated up.

How are the roller, presser foot and pressure adjustment used? I'm particularly interested in understanding the theory and the adjustment of the roller. Thank you very much for your help.

Btw, you may have seen how the presser foot has been ground down on the left side. I just realized the previous owner must have done that so the roller had enough room to operate along side of it. They had also stacked another, shorter spring on top of the pressure spring, apparently to increase the total pressure on the foot/roller/material.
