Hi guys - the casting kit I used was produced by Pinkysil - I picked it up at my local model club meeting although if you do a search online you will find it (admittedly the first spot I found it was on an Australian website). The kit came with a full tutorial... as each method may be different for each starter kit I won't go into details on how I did this (plenty available on the web for each product out there) but basically it involved making a two piece silicon mould in a makeshift mould box (first side made by pressing the items in clay, putting the mould box around the clay, pouring the first lot of silicon, letting it dry, flipping it all over and removing the clay, second silicon pour, then drying), clamping the moulds together and pouring in the resin - et voila.
I also decided to do some more on some of the other areas of the kit whilst I wait for the cockpit oil paints to dry... here is the kit's Bentley BR.II engine all assembled and wired up - no paint on as yet. The kit engine is in white metal and all 9 cylinders need to be assembled onto the crankcase - fun (especially when you drop the engine mid assembly and pieces go everywhere...

). That said the kit engine is quite nice - given that alot of it will be hidden under the cowl, all I needed to add were spark plugs, ignition wires, pushrods and the pushrod sleeves on the casing.
I think I will give the engine some paint tomorrow night. I think the engine will come up nicely after an oil wash.
