CI wants me to send them a photo but I suspect I'm drilling a hole in the back of the box and putting a grub screw in like those lib techs. My nephew has one that I can look at and try and match the hole.
Fortunately the boxes have always been way too tight so there's a lot of tension to hold the fin in anyway. Seems way too extreme to rip the box out and replace. Especially since where I am, quality surfboard repair is hard to come by. I do all my dings myself rather than letting some stoner at the surf shop keep my board for 2 months and do a shitty job. Don't feel confident doing a fin box.
I say this every time, but it's my last CI. The glass job is standard CI crap, already showing random dings after 5 surfs and the fins needed to be sanded to get them in the boxes to begin with.
Shame because I like the board. I guess maybe if I want another I'd get a varial or something.
Thinking maybe I angle the board and use a drill press. Perfect thing would be like a dremel tool drill press.
