Confused now. Didn't you say up there that the epoxy would eat the foam? -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l (Really) Sprint 1.7 75 TS 156 TS S2 Triumph Speed Triple: Black with extra black bits www.cuore-sportivo.co.uk
Now I come to google it I can only find Isopon Bumper Filler at 7 quid for 100ml ! Searching for that I did come across something called morphplast though which looked interesting - Ebay item 120018788440. Lozzo's composite solution with bobbins sounds good to me using whatever seems best for the filling with a harder layer on top and bobbins for the mounting bolts. The expanding foam stuff in cans is incredible but you would have to create a sort of sealed mould to contain it perhaps. -- +-------------------------------------------------------------+ | Pete Fisher at Home: | | Voxan Roadster Gilera Nordwest Yamaha WR250Z | | Gilera GFR Moto Morini 2C/375 | +-------------------------------------------------------------+
"Fibreglass resin" is polyester resin. Epoxy is more expensive and normally used with carbon fibre or kevlar, and for small repairs as it sticks to epoxy or polyester. I didn't know that either dissolved any sort of foam.
*Ouch* Not gonna happen And I need comparatively little. I think I'll just get some fibre re-inforced filler. That ebay stuff looks interesting but I doubt I could make it stick to the frame. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l (Really) Sprint 1.7 75 TS 156 TS S2 Triumph Speed Triple: Black with extra black bits www.cuore-sportivo.co.uk

That's the stuff, but it's not light, so the expanding foam with a skim of polyester is the route I'd take, but make damned sure that none of the foam can get where you don't want it. That'll require a couple of plastic bags being placed inside the "pocket" you're going to fill and all points NSE & W. Also, bear in mind this stuff cures pretty slowly so it stay "mushy" in the middle while it feels pretty solid on the outside. Leave it at least a day before you start carving or it'll pour out of the middle when you go at it with the knives. An electric bread knife is the best tool for that job too. -- Beav VN 750 Zed 1000 OMF# 19
Crossed wires or summat, but no, epoxy resin won't eat the foam, but fibreglass resin will. -- Beav VN 750 Zed 1000 OMF# 19
I think I'm gonna stick with the re-inforced filler. It's less than a litre and should do the job (I hope) -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l (Really) Sprint 1.7 75 TS 156 TS S2 Triumph Speed Triple: Black with extra black bits www.cuore-sportivo.co.uk

Well, if you're going to use polyurethane foam then allow it overnight to cure before trimming. Given that once you start a can of foam it's best to finish it, see if you need to fill any other holes around the house.
No it's not. Fibreglass resin is, believe it or not, for bonding fibreglass cloth/matting/panles etc which is nothing at all to do with polyester. It's "possible" to use fibreglass resin to bond polyester and it's "possible" to use polyester resin to bond fibreglass, but they're different and fibreglass resin eats various foams, including polyurethane foam. Polyester resin doesn't eat foam. Epoxy is more expensive and Fibreglass resin does. Ask any aeromodeller who's built foam cored wings and joined the two halves with fibreglass resin. -- Beav VN 750 Zed 1000 OMF# 19
"Fibreglass resin" is polyester resin: http://www.cfsnet.co.uk/acatalog I never use polyester resin as I have enough epoxy to last a lifetime.
