Chastity and orgasm denial discussion

I recently discovered spouts and tethers and am eager to give them a go, especially since I already engage in some urethral play. My main goal is keeping my chastity device fully secure without needing any piercings. It seems is the primary source for the specialized pins and washers needed, but their website appears outdated as of 2016, leaving me wondering if they are still operational. Does anyone know of other options besides doing metalworking DIY? I specifically need a hollow pin paired with a body-safe washer, which seems harder to locate than expected. Thanks!
