Drop leaf table repair?

[Acrobat]

Hi, I am doing a drop leaf table repair a friend has given me to try fix. The tops' boards were warping and have come apart. I have unscrewed all the fittings and removed the top- in about 8 pieces across. I am in the process of re-gluing these now. I had to joint the edges on each mating piece - a 1mm off each touching edge. I will leave the edges where the drop leaf sides fit as they are so it's the inner boards I am doing. The table is oval with a profile all around the outside. Now of course when I re-glue, they now longer match the outside profile as each board is shorter in width so I will next need to re-route a complete profile so it will all match smoothly when complete.
1: How do I go about achieving this? If I use a bearing bit will it not simply follow the existing mismatching profile? Do I need to create a new template and place it over it for the router to follow?
2: Whats the best way to secure the table top to the apron-leg base? It has screws up through the underside of the apron into the underside of the table top. Do I follow and simply replace the screws again? I have read screwing boards down can result in splitting as the boards may swell or contract over time.
Thanks

Photos would help but after reading your question a few times, here's some thoughts...

For attaching the top to the legs, you might use figure-8 connectors like these - Use a Forstner bit to drop the connectors into the rails at the top of the legs.  The design allows movement for the wooden top and should prevent it from splitting...

For matching the new oval on the narrow top, you might clamp up the top with it laying on a piece of plywood and mark the outside edges and then use a compass to set in a consistent distance - or use a curved stick to match the curve on each of the four corners by connecting the points around the oval, maybe 1/8 or 1/4" in from the old top size depending on how much material you need to remove.  Cut to that line with a jigsaw and then use a sander to smooth the curve and straight sides to the line.

That pattern with a bearing guided straight bit would let you recut the top.  Then you could route with your bearing guided profile with the new cut.

Yeah, I will try put some photos up tonight when I finish work. I'll have another think on your suggestions.
thanks

If you are only removing a mm slice you may find that the mismatch is small enough to be corrected with sanding only.
