I think the difference your looking at is the pressure treatment. A stabilized insert has been put in a pressure chamber to push the resin into the wood to higher degree than an impregnated insert. The impregnated wood is soaked in heated resin/varnish but not put under pressure so it doesn't get the same level of penetration. At least that's my understanding of the processes.
Either way talking about this somehow makes me feel dirty
Well... I live in Mongolia. And likely if i lived in the USA I wouldn't pay a tax regardless. I am not manufacturing heaps of fly rods.. I'm talking about building a few for some friends...
So maybe to appease everyone people could give a tax and a taxless quote/formula
If these are truly friends, then the price of materials and their gratitude should cover it. Since these seem more to be "friends", materials + whatever you think your times worth - quality of friendship, IE: how many beers they bought you. Realize that by charging above materials your taking on expectations should your work fail or they break the rod and want it fixed.
Also weigh the fact that by charging extra said friend will likely cease to be a friend should they become dissatisfied with the end result.
Are you writing on top of the epoxy or on the blank then coating with epoxy?
Your title suggests you writing on top of the epoxy? Why would this be needed?
Maybe for a bamboo blank?
On a painted blank a layer of epoxy helps the ink lay down better. I usually do a layer of epoxy, lightly scuff it, write on it and then do a second layer. Just makes it easier to write, especially with a gel pen or ball point. Some people just scuff the blank, that has never worked as well for me .
I have had a request for a short, 6'-7' or so, 7w for fishing small streams for pike. I think fiberglass would be prefect but have not been able to find anything that short.
Look at http://vintagerods.c...wulff/wulff.htm I've built these in 6', 7' and 8', super fun to fish and the owner sent scrap to add spigot ferrules on request. The 7' is a solid 7w rod, I usually fish a 6w Sharkskin line on the 6'. One word of warning, if you have him cut them he will cut them directly in half, would be better if you can get the cut offset to account for the ferrule.
