This recipe is from the Jean Andrews book "Peppers, the domesticated Capsicums": I have not tried it, so it's worth exactly what you paid for it.

Yield about 32 ounces

Steam the peppers with 2 to 3 tablespoons of water in a tightly closed plastic bag in a microwave for 3 to 4 minutes until the stems pull off easily, or use a conventional method. Drain thoroughly, remove the stems, and chop with the seeds. Put the oil in a heavy, deep pan, and add the chopped peppers. Bring to a boil; then reduce heat, cover, and simmer over low heat for 4 hours; repeat this procedure two more times (12 hours cooking). Strain through a metal strainer, pressing the pulp with a wooden spoon. Discard pulp residue from strainer. Puree the oil and strained pulp in a blender. Strain once more through a fine metal strainer lined with one ply of facial tissue, or through muslin or nylon hose. Return to a clean pan. Add the paraffin and melt carefully over low heat, stirring until completely blended. Cool slightly and pour into small, wide-mouth, lidded containers such as plastic pill bottles. Because of the long cooking time, it is good to make this amount.

There is quite a bit more and she recommends starting with Zostrix to get the pain under control then switch to this which is less concentrated but a whole lot less expensive.
