Now starting with the preparation of the carbon fiber.  I have been told that the more accurate the raw material fits the mold the better the final result.

So here we go. After spending a few hours to ensure that the template is exact size this is a cutout section of the template on the "mold" prop.  The actual blade color is blue can be seen through the cloth,

The carbon fiber I am using is plain weave 400g/m².  I will use two layers in the linear direction and then two layers vertical to this fiber direction for strength.  The strength of this cloth is in one direction and therefore I am having 4 layers 3 vertically to the direction of the standard cloth

Do they sell it per metre? What is the cost?

@Erastus  Wow!!! Congrats, wonderful project - your "blow by blow" is awesome, keep it coming... 

Just so happens that I have been Youtube'ing for the past few months on this very topic but for me, it is a pipe dream - day job get's in the way of me ever pulling a project like this this off.

Based in Durban interior and hope to be completely off grid in the not too distant future.  Winter is our best time for Solar but Spring and Summer is challenging in terms of Solar.  We can go an entire week with 100% cloud but thankfully we mostly have wind during these times so this is just what i'm looking to add to our setup.

Look forward seeing the final product once you have it all wrapped up... 💪

Did some shopping today.  Got all the goodies to make the first part:

For those who are a newbie to carbon fiber like me:

  • The roll on the right white and pink is "peel off ply". The peel off ply is used to give a smooth finish on the no mold side or the  back end of the part.
  • The blue section is like a mesh that distributes the resin
  • The roll on the left is the bag that will form the vacuum around the mold. In my case it will be cut in 1/2 and laid over the first section.
  • The spiral to feed the resin to all parts and then the seal of tape.
  • Blue pipe is between the "mold" and the container that holds the mixed resin.

That will follow next

Round Nr2.

Did some more checks on best practice and got rid of small cuts.  Replace the small cut carbon fiber with a triple woven carbon fiber  material.  Made a new "template" from fabric that does not give way in any direction.

Then started the layering processes.
