Howard posted a question about deep epoxy repair right before the message board blew up and consequently didn't get many responses.  This post has two purposes - (1) to provide additional info that may be helpful to Howard or others and (2) to test the upload and web page link features of the new message board. 

The image is a photo capture of a tips and tricks page of a farm publication I receive.  I have used this technique to rebuild an oak door threshold and it has held up well.  I used Bondo as the filler since it was not too deep.  The link provided is to a product that was recommended to me for doing high strength wood repair.  Judging by its reviews on Amazon, It appears to have some merit.  I plan to order some and experiment with it, but can't yet personally attest to its effectiveness.  Hope this is useful.
