As the title says,going to be making a 2 piece mould of a GSXR 1000
tailpiece,and I'm having trouble getting my head round it.The top is OK
it the underneath that's the problem,as you can see in the picture it
has a lip,so would the flange be best at 90 degrees or straight,as I
will be vacuum bagging the part when I make it,how do I hold the carbon
inplace.Hope I've made myself clear,in my head I know what I want to
say,but when it comes to writing it down it goes out the window.
Any advise is appreciated.

   Thanks Paul
