Hi there, Simon, Why not 'borrow' a traffic cone and use it as a temporary core (maybe borrow a term from sculpture and call it an 'armature') while you lay up a cone in fibreglass over it? The fibreglass cone should be plenty stiff if you lay up enough thickness. I think the sculpture term is 'armature' though that might not apply if you eventually remove it? Structural fibreglass (aka 'GRP') requires freedom from included air bubbles, complete wetting of the glass fibre by the resin and the correct ratio of resin to glass but your application probably isn't so demanding. Forgive me if you're experienced in GRP - I don't intend to try to 'teach Grannie how to suck eggs'!! I could write much more but I'll leave it at that for this post and await your response. |

I did once use the resin to waterproof a model boat when I was 12 or something, following a guy's advise. It was a nice idea except I couldn't get paint to stick to it. Sounds like a bit much for this project though. At the minute i'm just working up the courage to order some aluminium. I hate spending money! |

I'm having doubts as to what gauge i'd need to buy though. 1mm aluminium seems like it might be too thick. Looking at galvanized sheet steel, it's alot cheaper too so I might go with that. I'd like to buy it in person for this reason, but with no car I'm really limited to ordering online! I suppose I could also try phoning the steel stockists I usually go to and asking if they have any thin galv sheet. Edit: Also, sorry about coming across as so indecisive, but i've really got very little money left after finishing university. |

Simon, FYI I bend round stuff like that out of 24 ga. galvanized steel. I believe that works out to about .6mm. |

I guess i'll order some tomorrow. Found a website through google searching for 'galvanized sheet steel UK', and was looking at the delivery charges. "Remember you can collect for FREE from our premises in Tyne andWear. Your order is likely to be available on the second working day after being placed. Please confirm before coming to see us." What a coincidence! It's just over the river too, near where Doubleboost lives. |
