I think what BillA is trying to do is point you in the direction of useful references which should help you to gain the knowledge required to manufacture a heat pipe.

I am of the opinion that this approach is much more beneficial to the community as more people will gain the necessary understanding of cooling principles rather than the same people having to answer the same questions over and over.

That's not to say you shouldn't expect any help, but people are much more likely to get involved in a discussion if they believe that the others involved are as keen to actually go out and read around the subject and possibly bring something back to the table themselves.

With regards to manufacturing heatpipes in general.

Heat pipes are more often than not, a large scale product requiring very expensive and large machinery to construct effectively, hence the need for large quantities to be produced. This machinery can produce heatpipes at low cost, better than you could with quite a bit of money but none of the machinery.

The wick is a perfect example of this.

A common wick technology is to sinter copper powder onto the internal surface of the heatpipe, but this is not something you would be able to do in your home workshop.

If you want to make a homemade heat pipe, I would suggest using gravity thus negating the need for a wick.
