Looking good guys, as everyone has said nice to see a few pics along the way.

Once upon a time there was (i think) an offer of 'knocking a couple more out of the mould' in exchange for beer tokens? Any chance of that or have you been put off by the time involved?

Daniel

Where do you get the stuff for making this stuff up, and how much does it cost? Thinking of making the hulls for my RC RIBs out of fibreglass.

Looking good, keep us posted...

Cheers,
Matt

Testing and composites

Daniel we may produce another one or two, but the next really important thing is to give them a good old test, we hope to get the rib in the sea this weekend and will see what the seats work like, we are also waiting to have the backrests finished, these will just bolt on easily enough.The stuff to make fiberglass seats is very available, the mold is just mdf and we used easy sand filler internally in it, the two pack paints inside the mold are International products, the fiberglass resin we bought in a large 25lt drum with activator, matt chopped strand and woven roving matt,mixing bowls and a scales, actone thinners and actone resistant gloves,scissors some general tools measuring tape insulating tape knife, the relasing agent for the mold and wax to help release the seat from the mold, gelcoat filler and flowcoat, simple black and decker sander and plenty of sandpaper.Tim made a trip to a guy who works with fiberglass and he offered advice on what our material needs would be and we bought the specialised stuff from him the resin and the like.The biggest part of the project is time, we were at the mold for about 2 months of weekends, to get it perfect, and of course the inital cost is the biggest, once the mold is made you have it forever, seat molding takes about 4 days to cast , obviously this is a couple of hours a day and once they come out of the mold are cut down to correct height , wet and dried polished and mounted , this takes a bit of time ,but once again preperation is everything, and of course we did hit snags along the way, but the biggest commitment is time, cost wise, we kept pretty good records, I dont have the total right now ,but it did work out cheaper than buying them and they are custom made to our needs which is hopefully better, in the long run gavin

Gavin, brilliant, just wish my console had worked. The MDF gave a reasonable finish but I used a plaster to round the corners of the mould off (female mould) several coats of PVA made the MDF release okay but the corners and edges stuck and mading a horrible mess. Left with the choice of grinding the edges back to glass then filling and painting of buying a new one I botled out and bought one. Might still fix the DIY one at some point but OCean Ribs in Portchester offered a great console for 400 so I opted for that instead.

As far as costs go, I used 5l of resin for every 5m of 450 g CSM. 5L of resin and CSM (chopped strand matt) is 20. To calculate the quantity, have a think about how much the final moulding is going to weigh. If its a big console then 30 - 40 kgs. Since the CSM weighs very little the weight must be resin, therefore a 30 kg console is probably 120 plus any ply re inforcement and the MDF mould. Get it wrong and its expensive plus hours of work laminating GRP.

So good one Gavin, look forward to seeing the rib out on the water.

Pete

GRP materials

I get mine from: Glasplies, 2 Crowland Street, Southport, Lancashire, PR9 7RL. Tel.01704540626. Fax.01704 537322
They are very good. Prices are about the best. They often have cheap drums of resin. They will send you how to do it instructions and other helpful literature free. They also keep specialist resins in stock, they're open 7 days a week and they mail order. What more could one ask for?
I've no connection. Just used them for years.
JW.
