Hello all

Planning my first project.. I have included some photosbelow of the part to be replicated. Having lurked for a while I was hoping todraw on some experience here.. i have the large mould & high temp laminatekit from EC....

Mould construction

  • Would you build up the sides of the mould tomake the shape a complete ‘bowl’ and trim after, or using clay, construct anedge/flange following the contours of the shape..

Layup

  • ·        I had planned in the first instance to followthe wet lay technique shown on the video. What would be the most pleasing tothe eye to lay the fabric.. i planned to use two pieces of fabric due to theshape, firstly cap the top of the cowing using a circular-ish piece and use aseparate piece of cloth to cover the sides.
  • ·        Are there any issues with overlapping the cloth ..any special considerations in doing this,, will it look nasty.
  • ·        How many layers of fabric would typically beused to achieve the same thickness at the sample in the photos. this will besubject to vibration and heat
  • ·        Can i let each layer cure fully before addingthe next or should it all be laid in one sitting
  • ·        Can something of this deep bowl shape be doneusing a Vacuum bagging. Is there anything on the web showing this type of shapebeing made this way.. all i have found is flat or shallow panels.

Thanks

Hi
how did the head cowlings turn out?
Have you had a go with any other Lambretta parts?
I am looking to utilise some existing fibreglass panel moulds for my bike.
Best regards
