Good catch, Grump, SOME Vaseline in place of the oil in SL-68.1 would have more accurately represented what I meant.
FYI the Soap Lube series in my book goes through basic version 71, with .2 and .3 versions of SL-68 having been made and tested nearly two years ago. Don't ask, if there were anything that merited publication beyond the basic MW/Ivory/mineral oil/Vaseline constituents of the 68 umbrella it would have been. SL-69 used strictly beeswax in place of petro waxes, SL-62 or 63 (I forget) used straight paraffin wax (Brad called it "Flubber") and was part of the tranny-goo series (SL-61-65). Some of the low-60 series used straight beeswax same as 69, but were made in "reverse" where the wax was added after the soda grease was cooked and thus was not fully incorporated into the soap matrix. All of the soap lubes since version 1.0 have contained between 20 and 40% Ivory soap or 15-20% Na stearate granules, hence the "SL" nomenclature. Generally, though not always, if a major ingredient or cooking technique is altered, I go up a number. If a minor ingredient or combination of minor ingredients is altered, I denoted it as a sub-version. Look, I'm no laboratory scientist, I'm a grease-monkey turned parts man with a background in M.E., so I developed my own "system" of identifying recipes as an expedient that made sense at the time when the sheer data overload made simple names like "yellow jacket" (beeswax/various oils) or "Zombie" (anything using AC ester oil with tracer dye) obsolete. Runfiverun did a similar thing with his E-(color) series, a cookie to anyone who knows what the E stands for. The letter/number series that I eventually adopted let me keep track of changes easily and group trends, an important thing when drawing generalizations about the effects of an individual ingredient. For example, we can say with relative assurance that SL-62 and it's sub-versions has a tendency to throw cold-start flyers, but SL-67 does not. Comparing versions on a manual spreadsheet indicated to me that paraffin wax as a trend causes cold-starts in soap-based lube formulas, but Vaseline or mineral-based petrolatum does not. SL-67 proved the value of micro-crystalline wax as a major ingredient that keeps bore condition consistent under a wide range of temperature. Gradually I got it narrowed down, and SL-68.0 currently stands as an example of what to work toward with soap lube: Micro-crystalline waxes plasticized with straight-chain paraffin oils, with a dash of castor oil for high-velocity enhancement. SL-68.3 was the same as .1 except Maxima K2 ester oil was substituted for the Castor. It had the same problems as .1, though, which caused me to think that the way to test the castor would best be done with version .0. SL-68.4 was never made or tried by me, as I went back to .0 and .1 and haven't really found anything about the castor part of the mix that needed improving.
Jon's SL-68B is his own avenue of experimentation with some input from myself and others, and I think focusing on wax blends is a path worth taking. I'm very pleased that the basic concept of SL-68 has proven worth the time and effort of both him and Barn to take to the next level, and I sincerely hope that they can improve upon it even more. It has taken a village to bring up the Extreme Lube recipe, and continues to do so.
