Ever wish you hadn't decided to try and repair something?
I decided to try and repair my carbon tiller. It looks like it has already had some sort of repair as the carbon plate doesn't match the rest of the tiller. The screws that hold the block in place and the plate onto the tiller wouldn't do up properly so I drilled out the two lower rivets on the plate so that I could try to build up an area for the screws to bite into. As it came apart it looks like there has been some bad delamination in the past.

What boat is this carbon stock from? If it is a Phantom then it is possibly a Winder stock but I have never seen one in such awful condition.
Is there any manufacturer's name on it? The worn away bits look to be carbon and you would presumably need to lay up carbon in epoxy to repair these but could well need specialised vacumm bagging and a curing oven. |

I can't say I try and repair boats or fix things myself.... not much point with P&B up the road.
However I have spent 2 hours waxing my snowboard, first time making a right pigs ear out of it, hence scraping it down for an hour and a half. It would have cost a tenner to get some lank haired yoof in the local ski shop to do it.... lesson learned.

I agree with Yellowbelly, it looks like a job for a professional repair unless you have experience with working with carbon fibre.
Looking at the Winder lifting rudder stock from my Merlin, I can see some similarities. The large hole/gap at the top rear of the stock looks as though it was shaped to take a turning block for the hold down string but looks as though it was ripped out. Can't figure the role of the separate plate. What boat is it intended for? Suggest that you talk to someone like Linnell & Bax (Northampton), Phil 'dirtyhands' Scott (Hams Hall, B/ham) or Dave Winder (Lancashire) depending on where you are based. |

Did you have the correct application of beer during the process? Snowboard waxing is an essential group activity usually in the hotel or chalet basement which should always be left looking like a snowstorm passed through only the snow was made of wax scrapings... It takes so much longer that way.. |

Oh grief guys, don't exaggerate. This stuff ain't that hard. I'm no expert, but this is how I'd approach it.
By the looks of things its a rather scrotty repair which needs redoing because it wasn't done brilliantly the first time, or maybe an equally scrotty adaption to put the block in? Not sure what the gunge is without handling it, but it all needs to come off anyway and everything sanded back to good fibre. This is a pivoting rudder presumably, and we're looking at it from the back along the stock? Take all the gunge off and sand plate and mating surface back to good and flat. Take a good look at the resulting mating surface, it may be it just doesn't have enough area at the top. Glue the plate onto the rest of the stock with a nice strong (plenty of microfibre) epoxy mix. You want to get a nice fillet on the inside of the stock against the plate, so you'll need to do your best vet impression with a rubber gloved finger to smear it in there... Either leave the fillet quite clear of the holes where the block goes through, or else make the fillet doubly deep, it just depends what's practical. Review how much area ended up glued at the top. I fear it won't be much. If so it needs reinforcing. Radius the join in that area, and then run some carbon cloth - about 3 layers - from the main body of the stock onto the join. Hard to get it neat, but peel ply and pvc tape may help. Don't worry if it goes over the holes for the block. When all cured, cut the hole for the block out neatly. If you managed to get the inner face flat then just pop rivet it on. If you didn't and you have a big lump of filler instead then drill and use self tapping screws. Tapping the hole and using a bolt and loctite would be even better, but who has the stuff to do that? |

nope - I fed, bathed and read stories to the kids and then waited until they were asleep before beetling off to my man cave to try my first attempt at self-waxing.... not really doing much for the image of the sport is it

It is a bit sad that so many have lost the practical skills or the desire to fix things themselves. I think our consumer culture and lack of practical jobs has certainly a lot to answer for and I wonder if the majority will ever go back to learning the necessary skills to carry out simple repairs. Sure doing it yourself will probably take longer but there is an enormous sense of satisfaction once you've done it. I am wondering 'what have I done' with the deck of my Grad but I take the view that it has to look worse before it gets better!
