Hi Chris, A steady that is trying to push the work piece out of alignment with the spindle rotation will walk the part out of the chuck. Usually setting the size with the steady close to the chuck and then moving it to the working position suffices. Dave

Google "air vane governor". Used on lawn mower sized engines.

One could also make toroidal (doughnut) shapes using such a tool. Handy for the top of your Tesla coil, or if you're a topologist a starting point for a coffee cup ::) Dave

Ron, See pg 243 of Enco's online catalog. Listed under name Everede Tool. Enco number 376-9020 looks like the size you want. They also list carbide ro the same boring bars. Hope this helps Dave

If you want the nylon brass combo why not make a cylinder liner out of the thin wall brass tube as sold in hobby stores and make a nylon piston. I've made several compressed air motors using this tubing as it has a smooth surface needing no finishing for this use. Dave

Thanks guys for the kind comments. You guys rock! Dave
