Hey guys, I'm new to this forum. I picked up a horrible rotten mess recently that I just finished cleaning up. It's a 6'6 polyurethane fish with major rot around the fin boxes. After deglassing the fin boxes practically fell out. I removed all the rotten foam away from the boxes and rails but now am left with less material than I expected. I'm considering all options: Microbaloons, Qcell, 4 lb polyurethane pour foam. What are the pros and cons of each. I obviously need something strong enough for fins. Thanks guys!!
Oh man! So much ground to cover! But first we have a few questions for ya...ill let someone else go first
That is the perfect application of pour foam. 4 lb density if fine. I've used it filling in huge voids to replace fin boxes. You can also use a mixture of resin and microballons to fill the voids
You can get 8 pound foam thats white ,the rest is piss yellow Also dap low density can foam is very white and excellent for holes I actually used it as an adhesive to glue up an eps board blank
Wet the old foam a bit before you use the pour foam it sticks better to old foam I just dampen it with a mist of distilled water ,not saturate it
The corvid shit had me at the house so much i was bored so ive built 3 surfboards since april and workin on #4
I wouldnt put boxes back, really im over finboxes all my own boards nowadays have glassed on fins Mine are balsa glassed with 7.5 volan in a vacuum bag Boxes are good if your traveling and need to pop fins out or your a fin freak and have every fcs ,future fin they make In various carbon fibre whatevas fins are a lot stronger than the glass job on your board so the fins will rip out the box and some foam with it so i make mine to break off clean
I've been thinking about that a lit on my longboard but I like the options on my 7'2 custom mini me 4+1 but also would never need to change fins on any of my thrusters so I see the value on glasses in fins
Ive never actually seen anyone change their fins unless they were broken or something and ive never seen anybody pull out different fins at the beach either But im sheltered I had a star sytems fin fall out one time during a little storm, it was a twin fin Mutha fukka
Think i could only go right til i got another set of fins yknow unless i changed em cuz i wanted to go left
