Stella - help!!!! OK, today I tried out some testers, using feather palm wax, Robnat palm wax. I tried your technique for the relief holes. I test in 3" x 3.5" round pillars. I think I did it all wrong! I tried your techique, and I got a slushy mess, instead of something I could push down. I think I may have done it too soon. What do you use to push down the wax? For this size pillar, how many times do cut and push down? Also, once you get a combination that you are happy with (FO, wax, wick) and you see that it works after you test, both the 3 hour test and the power burn test with that size 3x3.5, do you test a larger size that uses that same combination, i.e., 3 x 6? Or do you assume that because it worked with the 3 x 3.5" it will work with a 3x6 and 3x9? I'm only talking about taller sizes, not width larger, obviously that would change the wicking, etc. One more question, on your power burns on the pillar palm wax, where you let it burn all the way down, do you care if it blows out the sides? Pretty much in all of mine if I let it burn for more than 5 hours, it burns out the sides where they get holes and very thin and sometimes they leak. Not profusely, but they do leak, but if I wick down, after the initial 3 hour burn, the shell is way too thick. Any suggestions? Thanks everyone! The information I've learned here has been invaluable.
