Avro Vulcan build

Been drinking Eric??

You'll be pleased to know that I've weighed the paint brushes and there is no difference in weight. So the G4 doesn't add weight to the brushes if they are cleaned with cellulose. [badass]

Maybe to see how heavy they are.

Touche' ! :lol: The Vulcan looks great by the way.

I do like what you are doing.

Had a pleasant Saturday working on the Vulcan. Modified the nose leg from a single wheel to twin wheel. This required milling out a new knee section. Photos explain it easier than writing it up.








Then hot wire cut some round sections from blue foam. Cut them down and glued them onto the underside. A bit of filling and sanding and they will be ready for epoxy glass coating tomorrow.

Ralph, have you found a foam that epoxy doesn't eat ? If so please tell me the brand !

That's an impressive bit of engineering!

Hi Crash

Not found a foam thats glue safe. So have to use different glues and resins. A bit of a PITA. Which resin to use on foam depends on the resin base. Polyester based resins eat foam. Epoxy resins are generally foam safe. The G4 Pond Sealer i'm using to cover the Vulcan is polyester based so eats foam. I will cover the foam sections with epoxy resin and the wood parts with G4. Most epoxy glues are foam safe. I use white wood glue and polyurethane glue to fix my foam parts down then cover in epoxy resin and glass (25g/m).

Most cyanoacrylate superglues eat foam, look for foam safe superglue.

Thanks Q. Its nice to take a break from the wood bashing and play with some metal for a change.

Thank you very much, that's very useful information.

UHU POR contact adhesive is foam-safe. It dries a bit rubbery, though, so you cannot sand any runs or dribbles off once it has set!

why dont you use the same as Simon on his depron models

I've never known epoxy to eat foam. :huh:

Mister old fart. The two pack epoxy glue is fine but for some reason epoxy primer eats it. Go figure ? For 90% of my glass fibre work I use polyester resin, which definitely eats it. If I can lay glass tissue on foam using epoxy resin I will be a happy man.
