Difficulties with wearing a device? discussion

I previously wore that same cage before it went into semi-retirement. Like you, I had to customize mine too. You'll need a good quality handheld grinding/polishing tool similar to a Dremel. Be sure to pick up special mizzy wheels for the job. After that, get sanding drums in various grits so you can work from coarse to fine. Finally, polish any rough spots using a polishing compound along with what's known as a 'Muslin' wheel. Whether your ring is an ergonomic shape or perfectly round, use calipers to measure the inner diameter at several points to determine your exact starting size. Next, mount your mizzy wheel on the Dremel and begin grinding in a steady circular motion, aiming for symmetry. Once you hit your target dimension (for example, moving from 40mm up to 42mm), switch to your sanding drums. Start with the roughest grit and progress to the finest to smooth out the metal. Conclude by using the muslin wheel with polishing compound at high speed to remove remaining imperfections and achieve a bright shine. Lastly, wash it down with soap and water to check if all rough spots are gone. You can also grind down and smooth the tube bands without thinning the outer ring too much; you want it to remain comfortable. Shop around for the best deal; I did a quick search to give you an idea of what to look for. Make sure your Dremel is powerful enough and capable of high speeds, otherwise grinding will take forever and you won't get that desired polish. Don't skimp on the tool itself—more power is better. Feel free to PM me if you have questions; I'm a goldsmith by trade, so this is my daily routine.
