Hi everyone,

I am new to this forum; first I would like to say thank you for easycomposites and talkcomposites for all the tips and ideas you have shared. 

Now, I want to make a mould for this blade. I am not sure where to put the parting line; and if I should make a 2,or 3 part mould. 

Can anyone help?

Pretty complex part for a fibreglass mould. Certainly doable, but it's going to be a lot of pieces. And when it comes to making the final part, if you aren't using pre-preg then you're going to have to lay them up separately. Which means bonding all the pieces together after they have cured. If it is just a project for learning then go for it, you'll learn a lot. But if you intend to use it for something that places it under anything more than very low loads, then it may be quite weak. 

As for how to make the mould, I think brainfart is on the money. 2 parts for the blade, 3 parts for the base, perhaps 2 if the angles permit. If we are on the same page then I think you understand where to put the barriers, but I'm a little confused as to what "space between the blade and the base" you are talking about. I'll try to draw a quick picture as to how I would flange it.
