I'm just wondering how many of you would be interested in a radius dish made from 5/8" phenolic resin(cutting board material) that would cost $375 for one dish without sandpaper and $400 with sandpaper. It would be a 2 week delivery. I know there are some builders out there who hate replacing radius dishes when they eventually warp, so these dishes would be stable as long as you had them. This would not be a normal product, but more of a custom request. Anyone out there interested? Tracy |

Tracy, I would be more interested in a dish made of aluminum? Thoughts? |

I actually asked my partner about that first, and he said his cnc machine did not have the capability to cut aluminum. Bummer 
The next logical choice was this plastic. However, it is really hard to work with, as it increased the time on the shopbot and damages the cutter heads a lot more than wood. That is why they are so expensive. Tracy |

Hi Tracy, It sounds like it would be a good product, but I've never had any of my other dishes warp. I usually glue on a 3/4 back to the radius dish, and they have lasted years without moving. I think you might find it hard to sell a $400 dish, but I applaud your thinking outside the box. Cheers! John |

Sounds nice, but too expensive |

Thanks guys! Obviously, this is not for the hobby builder, as you would need to be doing this full time to justify this cost. Hesh, as far as how long the dishes will last, it is too hard to tell. There are too many factors at force here to tell for sure. It really depends on the location of the dish and how it is stored and other climate factors. It could be months, or years, no one really knows. It's like that old commercial for Tootsie pop, "how many licks does it take to get to the tootsie roll?"

[QUOTE=Hesh1956] How long will a conventional dish backed with 3/4" MDF last, any one know? It may be that the economics are not there for a shade tree builder like me. But thanks for asking Tracy.[/QUOTE] I've been using one of my originals since 1986. 2 layers of particle board, not even MDF. It seems fine although I have to agree with Lance that aluminum would be cool. |

A UK maker, Craft Supplies, makes phenolic resin sanding dishes already. He only does 25' and 15' radius dishes a single dish costs ?44.95 ($80) and a two sided dish with 15' one side and 25' the other side is ?64.95 ($117) Colin |

I have mine for a few years and I do about 2 sets a week with it. I didn't even change paper yet. I have mine from 1" MDF ceramic tile backer board. Alum would be cool but that would cost an arm and a leg. I wanted to make one but the cost just isn't worth the investment. The Alum would be about $800 for the blank. That isn't including the machining cost. 24 inch alum stock inst easy to find john hall blues creek guitars |

I and my students dont even bother to glue the paper - just use a bolt and washer thru the centre hole, then hold it at the edges as you grip the bowl to turn it anyway, works fine for me for 6 years now. |

I would be interested in buying the warped ones. I like those better...they add a "uniqueness" to the equation. Preferably the warped aluminum ones. 
I think the price is too high but if you donate one to OLF for auction, I promise to bid on it.

Tracy, I'm happy with the last waterproof MDF dishes I bought from you. The phenolic to me appears overkill for most builders. I'd rather invest in a variety of your different MDF radius dishes for less cost and occasionally replace one if need be (though I expect them to last indefinitely). Just my opionion. |

Thanks for all the great comments guys. I thought it was over kill, but just wanted to check. If the aluminum was possible, I'd do it. The consensus is not to offer it, so that is what I will do. Great to hear your dishes are fine Don. I'm sure they will last many years. This waterproof MDF is great stuff. Tracy |
