I've never tried applying veneer with epoxy (if I was doing this, I would strip it all down to wood then use the PVA 'iron on' method I've described in a number of past threads. However, there are both advantages and disadvantages of this too so epoxy isn't such a bad thought).
But, assuming this is the standard flat-topped Sire Jazz, to use epoxy, I would be tempted to use a vacuum bag (like skate-boarders use or folks who want to store quilts in their loft).
- I would cut the veneer a couple of cm large all-round and use a decent medium set epoxy (I think I would probably use Z-poxy Finishing Resin).
- the veneer I would use would be close-grained, non-figured (the figured will likely split in the process).
- with luck, the vacuum will not only help you achieve the close, flat bonding, but also start to curve the veneer a touch round the edges
- when set, the excess veneer would be cut off with a single-edged razor or scalpel (must be super-sharp) from the top laying the blade from the top and using the curve of the top to use as a 'summit' for the blade to have point-contact only
- then I would sand along the line of the joint with a sanding block, starting with something like 240 grit and finishing with 320 or finer
I'll try and find some old pics of some of the things I'm talking about
