Weaver Leather Supply

​If you own an Adler 205, you already know it’s an absolute tank of a heavy-duty leather machine—but even a beast needs the right tuning. Replacing the inner bobbin case spring with this genuine-spec replacement was like night and day for my stitching! ​Before replacing it, I was battling subtle tension inconsistencies and tiny top-thread loops on heavy harness leather. The second I dropped this new spring in, the difference was immediate. Tension is butter-smooth and ultra-consistent now, even when jumping between 6-cord bonded nylon and heavy 277 thread. ​Precision Fit: Fits perfectly into the bobbin case with zero play or alignment issues. ​Flawless Tension: Clean, crisp, beautifully recessed lockstitches every single time. ​Build Quality: Excellent spring temper—doesn't lose tension after hours of continuous heavy production work. ​Don't let a tiny, worn-out $10 spring ruin the output of a $4,000+ machine. If your Adler 205 tension feels even slightly off or jumpy, replace this spring immediately. Best minor investment I’ve made for my shop this year!

This leather punch kit is simple and efficient

Good service. Saved me a trip to the store.

Patterns work good for me. The trouble i have is trying to find the leather i need. The reason I say that is i haven't completely understood the types of leather i can tool with such as predyed leather. The only other thing I have trouble with is when I place an order is seems to take what I consider to be a long time before I get my product.

Great leather and service thank you Steve
