Did you ever do paper mache at school ? well did you know that with a few simple materials you can easily make your own cowlings from paper ?,they are as tough as old boots as well and above all stand up to vibration well.

This is how you go about it-

First of all carve a block of blue foam into the shape that you want of the cowl,then wrap the whole shooting match with cling film stretched tightly over the former,cutting the block is easy with a bread knife but do it outside that is unless you want bits of foam everywhere !

Next cut some strips of brown paper about three quarter of an inch wide and let them soak in some water,now take a few strips and paint PVA glue onto them laying the strips lengthwise across the former itself,just keep going until the whole lot is covered,then add another few the opposite way,let these two layers dry out overnight and next day repeat the exercise,keep going until it has sufficent build up,place in the oven for about one minute and it will set like rock,now go outside again ( most of my modelling is done outside ) and pour cellulose thinners into the blue foam this will dissolve out any residue or you just might possibly be lucky and be able to just pull out the plug,allow to dry and then treat the new cowl with Toughcote fuel proofer,paint and then Toughcote again,make any necessary holes etc for neddle valve,fuel pipe etc and fit to your model,these cowls will outlast any ABS equivalent which tend to fracture with vibration,give this method a try it really works :yes:
