Ella ★★★★★

The spring fit perfectly into the drive lever shaft assembly on my SC4 lathe, and the 4mm x 12mm dimensions were spot-on. Installation was straightforward, and it restored the tension exactly as needed.

Leo H. ★★★★★

Was a bit worried about getting the right fit, but the 4 mm x 12 mm sizing matched the diagram exactly, and it slid right onto the drive lever shaft. Compression feels solid, so the lever snaps back nicely now. Took all of two minutes to install.

Eva ★★★★★

The 4 x 12 mm dimensions were a perfect match for the drive lever shaft on my lathe, and the compression feel is exactly what it should be. It seated cleanly with no binding on install. Glad I grabbed the genuine replacement rather than guessing at a generic size.
