Re: CSS PIONEER
Fascinating work, Nigel.
Do you use Vinamould because you can extract from the mould? (I imagine it has some give?) Can you make multiple casts from Vinamould?

Re: CSS PIONEER
Hi David,
Vinamould is very flexible, normally I would make a hard mould for these type of parts but the rivet detail would cause problems extracting the parts, so it would need to be a two part mould. Also with vinamould you do not need any release agent, and it copes with quite large undercuts, the down side is that the flexiblity becomes a problem on larger components, so I tend to use hard moulds when possible on large parts such as the main hull.
I would expect to get around forty parts from these vinamould moulds, another thing with this product is it is totally re-useable, so you can re-make the mould anytime you need to.

It sounds really good stuff. Where do you get it from?

Re: CSS PIONEER
It is coming on really well, Nigel.
Couple of things I don't understand.
-The hull is no longer bare tin - what is it covered with now?
-I don't quite follow the drawing pins but I take it they will form "location dimples" - for want of a better phrase!
One other thing. The separator is exactly on the centre line. Would there be anything to be gained by having it slightly lower? (To give more material which could be cut away in the final fitting of the hull?)

CSS PIONEER, HULL
HI David,
The hull is painted in etch primmer,to prevent rusting, and yes the drawing pins are locators.
The seperator's need to be on the centre line(widest point of hull)think about it...and you tell me why David !!
There will be no trimming to do, the two halves will be bonded together whilst sill in the mould, this will form the pressure hull, all will become clear.

Re: CSS PIONEER

I always apply 2 coats of pva,I put the first one on very thick and sloppy and then wipe it of with a lint free cloth,this leaves a very thin film of PVA on the mould,allow it to dry for about an hour, then apply another coat as if you where painting a door,smooth strokes of the brush and insure that there are no runs,what you see at this stage will come out on the mould.

Re: CSS PIONEER

I now mix and apply a layer of gel coat,this is bassically a thick resin I have added color to to the gel which is normally clear,always add the color before you add the activator,I cannot give you the mix ratio of gel to acctivator as this varies with each manufacturer,so allways ask for a product information sheet,another couple of points to think about at this stage,gel and resin generate heat when activated this is a serious fire hazzard, never add more activator than is recomended to either gel or resin,try to mix only as much as you need in one go,if you have acctivated gel or resin left in the mixing pot place it in a buckett of water or it will catch fire,one more point at this stage as daft as it sounds never make the mould the same color as the product,you cant tell where you have put gel on and where you haven't,belive me I have seen it done.
