cheers woody
still stuck, i want to make a mould and then fiberglass it so i can remake more shells. how do i do this. should i make something from wood first.
Yes ...Wooden form ......take a fibreglass impression... use the resulting mould to make numerous shells.
Make sure that you can release the fibreglass from the wooden former.
Google around ....Im sure that you could find some info.
There you go ........a quick Google and ..... http://www.rebelflyingclub.com/moulds.pdfhttp://www.rebelflyingclub.com/moulds.pdf
If my Knowledge and memory allow
For Casting
Create smooth template.
Creat wooden box horizontally cut in half.
Use liquid (forget name - to stop pieces sticking together)to coat template
Insert rubber mixture into bottom box
Insert template
Leave to dry
Recoat exposed template in liquid
Insert rubber mixture into top box
Lower upside down bottom box onto top
leave to dry
when all dry release the mold
Though for an RC car shell you may only need the top half!!!
For duplicationwith fibreglass
Coat the top/bottom mold interior with above liquid
Start laying out Fibreglass sheet with Epoxy resin when all points are done leave to dry
Remove fibreglass copy
Glue halves together if needed.
Though Ive never tried this, thats what I think happens in some cases. Constructive criticism please.
If you do several layers for added strength put the weave of the next layer at a 45 degree angle to the previous one.
Sorry, just doublechecked it - What I said was a resin cast.
I put the error on dividing my attention between my signal processing assignment and this.
