thats a fine looking pull you got there, and again the craftsman ship is top notch. what does the gel coat do? i don't have much experience with fiberglas  so far i've only used it to reinforce my joins on the skirt and base.

hi, gelcoat is a thick coloured resin, painted on prior to the fibreglass matting. It sets hard and sticks to the matt to form the shiny finish.

i see. it's like the "foundation". do you let it dry completely before you apply the matting layers?

paint on, let it go tacky to the touch (approx 3 to 4 hours), then apply resin/matt.

I paint 2 thin coats of gel, each 3 hours apart before resin/matt.

I do this to make sure its not so thin in places that you can see either matt or sunlight through it.

the dome has been polished and filled where there were imperfections and then placed on a board ready to make a final mould from it.

theres a risk that it might get stuck, as it has no sticking out edges to pull on, so I'm hoping the 3 tiny drill holes I've made in the ears/eyestalk will let me blow it free with my compressor.

fingers crossed

Looks like a Dalek mixing/salad bowl.  Tasty.

Understood. I just had this vision of loads of people signing up here for a GRP replica, closely followed by the guys in suits and stern faces...  :o

funnily enough, thats what some people advertise them as on ebay-lol

well the new dome is made and the boring but time consuming progress of getting it ready to mount has taken place since my last update.

the head dome needs a flat base inside to rest on the neck wheels, so that it can rotate when the dalek looks left/right.
This flat base also supports a bracket to hold the eyestalk pivot, allowing the dalek to look up/down.

here's a pic of the flat perspex base (yes i know it looks like the face of the marshmellow man on Ghostbusters-lol)

Also, you can see the blocks of wood glued to the inside of the head dome that the base screws onto, and a cardboard mock up of the final piece of fibreglassing to make (the cowl that bolts to the front of the dalek head dome, like a visor).
