There are splinters inside the crack, from one side to the other, which I h ope will help grab on and hold the epoxy, aiding the epoxy to hold the halv es together firmly.
Questions: 1) Do you think the epoxy, alone, will hold the two sides, as is, firm enou gh, so that there is no flexing at the check line? OR..
2) Would you recommend putting dowels, diagonally, on/through the top and b ottom (3-1/2") edges.... not on the faces, to help secure the check line fr om flexing? I'm considering applying dowels. I don't want to use metal b olts.
3) Once epoxied (and doweled?), should I clamp the crack more closed, or sh ould I leave it as naturally open/wide, as it is unclamped? If I clamp it , I'm wondering if there will be a significant spring-back, once the clamps are removed, hence compromising the epoxy bond. It's hard to tell how mu ch force the spring-back pressure is, when dry clamping & releasing. It ta kes some good strong cranking, on the clamp handles, to close the crack by 1/4". The first 1/8" closes fairly easy.
4) Is there any other options to consider, for further securing/preventing the flexing at the crack line?
Thanks for any help. Sonny
