Early in Fine Resophonics history I seem to remember some 2cone resonators. The cover-plates looked very `space age` has anyone go one???
I`ve had an idea using 2 9 1/2" cones and would like to learn what not to do.
The project will need a cast ali. `bridge` joining the 2 cones, which (I hope) might give a more `Dobroish` sustain.
The use of my `Full-Metal-Jacket` cover-plate would mean a `normal` looking guitar would have something extra `under the hood`
Thoughts please

Hi Pete, There were some unusual designs in Fine Resophonic's early period, but none to my knowledge were duo-cones, they were single cone and Tri-cone models.     Shine On Michael |

Strange, I remember getting a business card from Mike (25years ago) with what looked like a 2cone creation. It had the same look as the blue guitar above, but with a longer handrest/cover that looked like it covered 2 cones...... Maybe I`ll be the first to make one?  PT I was thinking of an old Eko body to try the idea out , but 2x9 1/2" in a 20" body gives no room to `mess about` so I`ll put it in a `Box Dobro` A bit like this single spider cone  |

Have started, and think I can squeeze the 2 cones into the Eko body. (see also the `Cast spider/ bridge` thread which is my search to get someone to make the `H` bridge that links the 2 cones)
It is going to have a VERY long neck...

Here is a pic of the wooden `plug` that the cast bridge will be made from.  PT |

Fab project! We did some alloy sand casting at school a million years ago, any joy finding someone to make the spider? I' guessing the cones will run North/South parallel to the neck, I wrongly assumed the would be side by side East/West.
Good luck keep the pictures coming, I love this sort of thing!
Paul
Edit, read your other post, caster found, game on!

Work goes on.......  Its having a 3/4 ply `8` shape for the cones to sit on, then 2 half guitar shapes that sit on top that form the edges of the cone seating . The `8` shape has a `handle` that sticks out, and make the heal to which the neck will be glued (or maybe just screwed like a Fender) PT |

My casting will (I hope) happen at the beginning of next month , as a test/demo. for new students.
If it fails to get done I`ll have it cut out of a block

Could you mould it from epoxy resin?

Could you mould it from epoxy resin? Paul If your talking about the bridge..... I think the bridge has to be very stiff, if it has any bendiness this may remove attack and volume . It a `gut feeling` that epoxy would not be good. Carbon fibre might fit the bill but lets try casting first PT |

Here is the ply shelf fitted,(well just pushed in ,before final sanding etc.) I`m wondering if I should put in some baffles to make the under-sides of the cone separate from each other? Each would have a number of holes (there are some in the bottom bout already) to `let the sound out`. Any thoughts?  PT The rather uneven edge of the guitar will be cut about 20mm from the edge , then some sort of top (maybe a `Full Metal Jacket`) will go over the whole thing |
