I used Mt-13 quite a few times with good results. I used JB weld and this one as I was leaving for Haiti and didn't have time to order the MT epoxy. I am working on and so far it is holding. I'll let you know in a few more days when I finish getting it tillered and shot in. Its a bamboo backed, ipe core and purple heart belly. Got it off of James Parker's table as it had a african paduak accent stripe in it that had cracked. He had discarded it along with a nice bamboo recurve that had some twist to the limb. I took them both off his hands about 2 years ago and am finally trying to save them. I cut the bow in half so I could cut out the cracked paduak and put in some new riser material and made it a take down. Holding up so far and hoping to give it to a friend in Congo next week as I am off there do so some fish farming work for three weeks.
