The lower lag bolts on my swim platform bracket holder have stripped from the hull. I need help with how to best repair the hole so I can re-drill them bolts in. I know I can possibly go up in size on bolt but I am not sure I can find the right size. So I assume I need to fill the hole with Epoxy and some type of thickener. But should I do anything else, Should I enlarge the hole so there is more to hold onto? How big should I go? I will also probably use the same method to deal with the stuck lag bolts on my swim platform as the only way I have been able to remove the bracket was to drill out the screw holes. ------------- 96 Super Sport Previously: 95 Sport Nautique, 1980 Ski Supreme |

Paul, Clean out the holes by drilling them slightly larger. Then fill them with thickened epoxy. I like to "prime" the hole first with straight epoxy before adding the thickened. Through bolting is an option and really is the best way. Also, keep in mind the bottom fasteners on the brackets really don't have a load on them. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Thanks Pete. Since the holes for the platform are horizontal is thinkend epoxy thick enough to stay in the hole? Or do I need to do something so I doesn't run out? I can't through bolt as the location is below the floor of the boat. ------------- 96 Super Sport Previously: 95 Sport Nautique, 1980 Ski Supreme |

Paul, Just put some tape over the hole after you get the epoxy in it. BTW, some have cut a small section of the sole (floor) out at the aft to access through bolting. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| Have you guys tried ‘CABOSIL’. Works good. Turns epoxy into thick peanut butter type texture. It is micro sphere glass. Hangs good on vertical |

Can I use Total Boat Thixo cartridge to fill the holes? ------------- 96 Super Sport Previously: 95 Sport Nautique, 1980 Ski Supreme |

| I see. Looks really good for some stuff. Let’s see what Pete thinks. I can mix up 1/2 once of the marine epoxy w cabosil in a cup pretty easy. Cartridge might be waste |

The Total Boat line of products is great and at a very good price. Cartridges are handy but for small jobs can be a waste. Yes, you can pull the mixing nozzle, cap the cartridge and then later put a new mixing nozzle on but, if it's more than a couple days, the resin can harden at the tip of the cartridge.
As Daryn mentions, I too find having a small epoxy kit (resin and hardener) with metering pumps is very handy. You pump what is needed and add the filler of your choice depending on what you are doing. I would go for a quart Total Boat kit in a medium cure so you'll have it for many projects. I've had resin and hardener for years without any problems with "shelf life". For fillers, I keep micro balloons for fairing, silica for general filling and milled fibers for structural on hand. https://www.jamestowndistributors.com/userportal/search.do?freeText=epoxy+fillers" rel="nofollow - Fillers ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| Thanks Pete for details. When I was at store selecting fibers I noticed one type was very very heavy like lead (milled). And the other felt like nothing was in container (cabosil). |

Corvette people work fiberglass frequently, most I know use paper cups for mixing the fiberglass. Small dixie cups. Mix what you need and throw away the container every time. Fiberglass does not clean up well so it saves trying to clean out mixing containers. They say to avoid the cups with wax on the paper. ------------- |

Pete I bought the three fillers you posted in the link. What do you recommend for filling the holes? ------------- 96 Super Sport Previously: 95 Sport Nautique, 1980 Ski Supreme |

I'd mix some silica and milled fillers into the resin. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Thanks, got the holes filled this past weekend. Went much easier then expected, I though the epoxy would run more but with the silica is was nice and think and filled the hole. Leaving it for the week to cure and will replace the bracket next weekend. Thanks for the help. ------------- 96 Super Sport Previously: 95 Sport Nautique, 1980 Ski Supreme |
