    Question Putting a glossy finish on corian?

    I'm currently working a project where some corian needed carved detail. After turning, the basic corian blank ended up with a high gloss finish (naturellement! ) however the carved section is giving me trouble.

    I've wet sanded down to 2000 grit but it's still a satin matte. I suspect that some EEE on a buffing wheel would give it the gloss I want, but the carving's fairly fragile and has some deep concavities which more or less rule out that idea. Does anyone have any other ideas as to how to put a gloss on it?

    (I've a sneaking feeling that I'll end up taking the gloss off the rest of it with some sandpaper to match the carving, rather than t'other way round. Still, I'd prefer a gloss finish if I can manage it.)
    I may be weird, but I'm saving up to become eccentric.

    Flood it with CA?

    No warranty express or implied here; never tried it. Just read what our N. American cousins seem to be able to afford to do.

    Polishing with a Dremel & mini buffing wheel?


    The beatings will continue until morale improves.

    I would go along this line, but the Dremel is way too fast. Given that I have a flexible attachment for a drill with a 6mm chuck I would make a small lambswool disk for it and run it at 1400 rpm. Haven't tried it before, though, this is just theoretical thinking. Good luck required and wished for!

    Hmmm... thanks for the ideas fellas. I'm not to keen on the CA idea, I seem to have developed an allergic reaction to the stuff. Too many pens, I think...

    But I do have a Dremel... and it shouldn't be too hard to rig a reduction pulley between it and the flexible shaft. (He says with fingers & toes crossed.) Or maybe rig something to drive the flexi-shaft from the lathe? Hmmmm. [ponders]

    I'll keep the CA in mind as an emergency fallback option, though!

    What about using Liquid Glass, Envirotec or similar, they have a full gloss finish straight away. Even casting resin will work, but heat it to make it very thin as not to fill your voids, unless filling them is Ok.

    Skew, you really don't have any power drill at all? I use an ancient B&D. The Dremel might not have enough power to drive the flexible shaft even with hardly any load, it could burn the motor in just a couple of minutes (unless we are talking different tools - mine is only 110W). The lathe should be fine, a pin chuck should be enough to hold the flexible shaft. And pardon my ignorance (I was ashamed to ask, considered that it is in every other post I was hoping to pick it up, but couldn't yet .... What is CA?

    Superglue. Or more correctly: Cyano-acrylate.

    My flexishaft is actually for the Dremel, so I've no concerns there. I do have a power-drill that I could use, but with such a small mop I'm not sure I need to drop the RPM quite that much.

    A bit of experimenting on the morrow (sometime after the Melb. BBQ) will let me know one way or t'other. Hopefully it'll be a simple, straightforward task. [fingers Xed]

    F&E CA stands for "cyanoacrylate". About the same as Super Glue & Crazy Glue. There's also an Accelerator to set it instantly & Super Solvent to remove it from your fingers. Best brand I've found is from Woodcraft.

    I call that "skin."

    Super Solvent to remove it from your fingers.
    ...and that, "Nail Polish Remover."

    Beat me to it, Skew. Guess that's what happens when one types with their middle finger & uses the backspace bar every few letters.

    Thanks for getting me unstuck with superglue (what a terrible pun! )
    So the problem was not my motor smaller than yours, it was my shaft bigger than yours... Glad we sorted this out!

    Cheers

    Actually, now that I think on it, I have a miltary dentist's drill from the Vietnam/Korean war era. Both 240VAC & treadle power, for fairly obvious reasons. I wonder if I have a mop to fit it?
