I dissembled the old tiller that was cracked at one of the laminate layers, broke it into two horizontal pieces roughly along the de-laminated section, applied copious amounts of liquid nails to both sides, and put the two halves back together using several vices. A lot of extra glue came out the sides, but we wiped it off before the vices were put on. Then we used q-tips to clean the glue out of the existing bolt holes. Hopefully, this repair will hold better than the jury rig I did in San Carlos. Once it is dried, I will bolt the metal straps back on and the old tiller will, hopefully, serve the remainder of its life as a back-up emergency tiller.
