“The El Cheapo way to make a Generic cockpit”
By Mark Fordham

The other day I was sitting there at the modeling desk using a hot glue gun unsuccessfully trying to glue a piece to a wooden boat when I put the Hot glue gun down without looking what I was doing. Next thing I noticed that all the hot glue had dribbled out all over the workbench effectively covering the half completed Pavla P40 cockpit I was working on.

 37 choice words later I carefully started to pick at the dried glue, thinking that the cockpit was a write off I gave the big glob of glue a hard yank. next thing I  know the glue parted ways from the resin without damaging the parts. I was just about to flick the dried glue at the cat in disgust when I noticed that the glue had a pretty good impression of  the P40 cockpit embedded into one side Hmmmmmm.

 I've seen a few articles on Resin casting and using Silicone or latex as a mold agent but never hot glue “glue” so this may be of use to the budget modeler who cant get or afford those resin upgrade cockpit sets.

  Tools Needed.

Glue Gun

Glue Sticks

Small piece of Glass

Tin of Bog (Bondo)

Master of whatever you want to cast

 Well after that long winded intro here’s what I discovered. Mount your  master cockpit side in this case a Resin P40 one onto a piece of glass and cover it with some type of release agent (I used spray on Chef aid oil). Turn on your Hot glue gun and leave for at least 10-15 minutes until it is very HOT, If the glue isn’t hot enough you get a lot of air bubbles in it as it comes out. Once the gun is hot slowly cover your resin master with the glue making sure that you go slowly and evenly over the part, paying particular care to avoid air bubbles and making sure that you get the glue into all the nooks.

 Leave to dry for about ten minutes then carefully peal the hot glue off the resin master, if you managed to cast the glue mold without any blemishes or air bubbles you now have a resilient but flexible mold. The glue can hold a fair amount of fine detail, not quite as good as resin but far better than the kit supplied parts.

 Now it’s time to reproduce that cockpit panel, as this is a low budget tip I stayed away from the expensive casting resins that are hard to find. Instead I used common garden verity car Bog, Plastic Putty or Bondo to our US friends, this stuff is dirt cheap and a tin can last you a lifetime unless of course you spent a lot of time driving by feel! The tin I have was purchased about 4 years ago and is mainly used for filling very large holes caused by my more disastrous screw-ups, on models not the car!

 Mix up a small amount of filler and hardener, go light on the hardener as it will make the finished panel less brittle. work in the bog into the mold making sure that you get all the air bubbles out again. One trick that I do is slightly overfill the mold and then flip it right way up and push it down onto the glass until the bog dries. The bog will not stick to the glass or the hot glue  and once dry you can carefully “pop” out the finished panel by flexing the mold from side to side.

 By making two molds for each side, In no time I cranked out 25 “generic” 1/72nd scale cockpit panels in about 30 minutes as thin as the original resin ones with 98% of the detail. Remember that the sample shown in the photo is only 18 mm long and 10 mm high and once painted and dry brushed look as good as the original.

 Flushed with this new found success I went Glue gun mad and in a short period of time successfully managed to cast radial engines, control panels, radio boxes and even wheels by doing them in two halves. I even managed to cast  replacement exhaust stacks for a Mk I Airfix Spitfire that the carpet faireys ran off with.

 As much as I support the small garage resin operators who’s only product is the Fruitbat Mk22 cockpit panels and resin replacement seat there are times when we can really can only afford to splashdown that money on one set and those other 14 un-built Fruitbats sitting in the kit dungeon are going to miss out. So here’s were this idea can work out, use the Acme supplied cockpit panels as a guide …scratch build a master set for the rest, make hot glue molds and knock out the other 13 in about 19 minutes. easy!

   Now this feature will only be of use to make side panels and boxes for models, and is of no use for undercarriage legs and such, it is still a cheap and useful way of casting those odds and ends that can take up a long time to scratchbuild. So far I have only done 1/72nd scale stuff but looking at the quality that the silicone glue can hold there is no reason that you cant use it for casting more complex shapes on bigger scales.
