Major lamination crack repair
HTML-код
- Опубликовано: 8 сен 2024
- The hybrid recurve build that I did recently was fraught with setbacks and road bumps. The heating process needed to get the shape right is not very friendly to laminated parts and as such, I suffered a couple of different delamination issues. This video shows how to recover a major crack in the lamination between the backing strip and the core, and also discuss practical ways to avoid this type of failure in the first place.

Pretty clever idea to use the shop vac to get the glue through 👍🏻🙏🏻
havent tried vacuum! I wrap the entire area with clear box tape and inject it in through the middle and poke a hole on each end on bottom at extreme ends so the glue has to go entirely through the crack. you can watch the glue through the clear tape. hardest part of the process is getting a good seal while injecting. i use uv cure glue to seal since its instant. works for longitudinal cracks as well. i think ill try your vacuum method combined with my method. since theres two holes on bottom you would have to plug one at a time. and
Very intriguing method… I like it! I will definitely be trying it in the future!
You truly impress me every time you save a bow. I just had to do this to my laminated bow. I didn’t use a vacuum though. Your knowledge I appreciate so much. Great job.
i always learn something new about bow building watching your vids, that vacume thing was pretty slick. Keep up the great work and sharing.
greetings sir and everyone. what a smart idea.yes very impressing.i must document this.

A work of art!
Any idea of performance compared to past builds?
This bow is definitely no dog… I would put it against any of my RF/DF builds and suspect that it would easily hold its own. That having been said, a Chronograph is the great truth detector… I’ll try to get out soon and speed test this bow against previous ones.
Much appreciated!
Hi! I got a situation with a bow and maybe you could give me some help. It´s my cousin´s longbow. It´s a laminated ASL. I don´t know what type of woods are in it but its seems to have fiberglass in the back and the belly. The matter is that the upper limb has some serious delamination (the belly´s fiberglass almost completely falls apart) and it has a pretty severe curvature backwards. Do you think I can heat it back into its original shape and then glue it with epoxy? I´m not sure what will happen with the rest of the limb if I apply so much heat and if it will bend into shape at all.
based on what you are describing, you have a pretty severe hinge in that limb. I wouldn't be very optimistic about salvaging a bow damaged to such a degree... for starters, I'm not sure what you would be trying to accomplish with a heat treatment unless it's to try and straighten the fiberglass (which I haven't tried and don't believe that I have seen any information out there that would suggest that the method would work.) And secondly, you can't just salvage a severe hinge with heat. Lastly, if this damage occurred as a mode of regular use, then there is clearly a design or construction flaw in the bow... Heat and epoxy cannot fix those things. All that having been said... what are you going to do with it now? Doesn't even sound like it would look impressive hanging on the wall as decoration or in any part of a collection, so what do you have to lose in trying? If the damage isn't as bad as I'm envisioning, you may be pleasantly surprised with your repair. If it does't work - well, then you went down trying to fight the good fight. Either way the bow will eventually end up in the trash... I still would resist the use of heat, unless there is a very compelling reason coupled to success... Good luck!
@@meadowlarkadventuregear thanks!! I'll give it a try and at least it could be "hanging in the wall" worthy
greetings
Sir, what glue are you using for repairwork?
I used Smooth-On EA40
