I've got a number of oak bowl blanks (about 10" diameter by 3-5" depth) that are starting to crack. I intend to rough turn them as soon as I can, but some are already cracked beyond what I'm comfortable trying to turn. For most of them, I'll probably consider re-cutting to make smaller blanks or maybe some spindle stock. However, I thought for one or two it might be interesting to experiment with filling the cracks with epoxy (after the blank has dried a good bit more). I only have experience using the normal two-part epoxy, so that is likely what I'd try -- maybe with some added dye or filler to give it some color.
My question is regarding the strength of the epoxy. Given the size and the weight of the blanks (not big for most of you probably, but for me, this will be the largest bowls I've ever worked with) and the placement of the cracks (most are very nearly centerline), will epoxy be strong enough to hold the piece together? The last think I want is for the piece to come apart on the lathe.
