Location: Scotland | If you’re using a Spider cone you will need a 10.5 inch hole or 9.5 for a biscuit cone. For the spider type the actual hole will need to be very slighty bigger so the cone can be installed and removed without binding on the edge.
In this case the soundwell is just glued and clamped to the top. Bear in mind that Spider cones don’t actually need a soundwell. A lip around the hole to support the cone will work fine. If you install a soundwell you may need to support it from below. On Dobros with soundwells the soundwell connects the top to the back. |

Location: NJ | If I hadn't packed-up MasterTempleman's ResOvation (yesterday) for upcoming TransAtlantic PingPong, I woulda' posted a pic of the inside to show what the guy who adapted it "did" . . .
Basically, a wooden ring that was glued/screwed to small, wooden blocks (of varying heights) that were epoxied to the inside of the bowl at strategic points to evenly support the ring . . .
QuiteTidy. |

Location: Pacific Northwest Inland Empire | Depending on how hard you want to work at this, I suppose you could derive the contour of the bowl, directly below the hole in the top, and taper the soundwell ring to fit it. The spider cone design on my Matrix project was a lot easier, since I didn't use a soundwell. 1/8" ply top, with a 1" ply support ring. Getting it DEAD flat is the tricky part. Not all cones are DEAD flat, either!
Best of luck,
Chris |

By the time you install the new kerfing & attach the new top, it should hold soundly, anyway. And, if you route the edge for new binding, even better. |
