wowzers man that is nice!

YOUR iron will totally rust away long before you would ever need to fill that bottle 9 more times. your math is great no doubt but what about the other 95% of the liquid in the bottle called water ? the another variable for you to figure out as the water is also acting to dissolve the iron and it is also holding the iron in suspension also. Your making this way to hard, The vinegar is only used to hasten the iron oxidizing away if it mixes that doesn't matter. its the quantity of iron to the tannic acid that makes the leather black. Vinegar has nothing to do with that process so it doesnt matter about how the iron and vinegar attach to each other because thats not what makes leather black.. The reaction between the iron and the tannic acid in the leather is what makes leather black not vinegar Here is how i would get the info you want. you would need several samples (10 at least in glass jars with lids) all weighed exactly and large enough to get a measurable variance of numbers, each day or time period you designate take one sample weigh it, subtract from the original weight to find loss from evap and gassing off , take out the steel wool dry it and then weigh it. from that you can find out how much iron you have left, you can also find out how much liquid you have left, percentage of steel wool in suspension etc. you can also test the solution ( timed dip test test and total immersion) at the same time on leather that has been tested for PH to see and verify actual visual results. you could also test different leathers with varying ph levels during your study.

So in essence you wont know any more than when you started. you would need several samples (10 at least in glass jars with lids) all weighed exactly and large enough to get a measurable variance of numbers, each day or time period you designate take one sample weigh it, subtract from the original weight to find loss from evap and gassing off , take out the steel wool dry it and then weigh it. from that you can find out how much iron you have left, you can also find out how much liquid you have left, percentage of steel wool in suspension etc. you can also test the solution ( timed dip test test and total immersion) at the same time on leather that has been tested for PH to see and verify actual visual results. you could also test different leathers with varying ph levels during your study. FUN FACT ==== when drying your steel wool, to find out if it is indeed 100 % dry lay a small scrap of paper on top of it, if the paper curls up the steel wool is still wet and is giving off vapors that affect the paper. Don't know your age or education level or any of that but speriments like this was about 5th grade level science when i was in school. I also spent a year or so doing testing for the highway department, testing compaction , asphalt, concrete and so on. back then it was all old school basic science no special meters or anything. a lot of grading, washing, drying, weighing and a calculator lol.. not nearly as interesting as the science involved in drilling an oil well. Now that is some sciency stuff there my friend ever see actual oil shale from 10,000 feet down?

I like it!! And the hatchet.

even doing it with machines is labor intensive and wet, very cool videos Fred, do you notice how big the drums are comparative to the load they put in it. You would need a cement truck i think lol.

Carp is the first thing thing i ever hunted with a bow, Taking one with the first shot first shot got me hooked for life that was in 78. I still have the same bow, spool and arrow lol. Sweet little Browning Wasp 50#. Good luck to you as well my friend.

they do tumble hides to break them but the size of drum you need makes it all but impossible for a hobbyist type tanning setup. they have to be huge.so the hides don't ball up.

i'll be bow hunting them in about three weeks lol. No turkeys around here for me so Carp will have to do lol.

oh yea, that's cool indeed! Tanned carp is interesting might have to try that.

Why do people think leather hasn't been studied to death???? Humans have been using it longer than science itself. lol so much for " people with more of a technical background" knowing shit about anything i guess none of those Brainiac's prolly know about these. https://archive.org/details/pub_american-leather-chemists-association-journal We've done a half dozen hides since this post. Some things are as easy as they are ever going to get on a small scale project and there's a time when you just have to accept that, roll up your sleeves and work hard. Don't worry though its actually good for you. Thank you i appreciate that information but NO, I'll pass i couldn't find any info anywhere on that product. I'm not chancing ruining a hide I've got so much work into already.

here is an archive of tons o books on leather science. this site a good start on finding what you want just search leather but this book has info on your speriment you may need. https://archive.org/details/dli.bengal.10689.10394

I too love a good experiment and am looking forward to someone who can for once say it takes x amount of steel wool in y amount of vinegar of a given strength for z amount of days to get a solution of ?% iron That works on leather with ? amount of residual tannic acid. How did you set up your experiment? How much steel wool did you use? how much vinegar? By now you should have data that suggests how much the steel wool is reduced daily by the vinegar. How have your measured that? What is your method to find out how much iron in solution and tannic acid it takes to achieve Black in an average piece of leather? what is your method for testing the residual tannic acid in leather?

folks who know which side the feather should traditionally go on certainly will be giving him attention. maybe not the kind he wants.

yea pretty much , here's the deal the vinegar is simply to speed up the process of reducing the iron(rusting it away) and putting it in a liquid suspension . You could use plain water but it would take much longer than the vinegar. It doesn't have to be exact in any way and its about as sciency as putting a mento in diet pop. If you use stronger vinegar then you also put stronger acids on your leather which isn't good, neither would be the oil you wanted to put on top of the mixture to keep out air. Remember the end result is to produce a liquid you can put on leather, dye it black, and not ruin it. There are more than a couple of threads on this topic it may be good to read through some of them, there are also other ways to make the roon. Good luck!!!

nah you can use a dodge or chevy too lol Seriously i think its to hold the passes into the national parks, in the big ones you gotta pay to see land belonging to "the People" so he would need one in Yellowstone. a regular pass is 35 bucks for seven days meaning you can come and go from the park and get back in with the pass. Oh and one also for grand Teton park that you also travel through at the south end.

the feather on the right signifies its a womans hat, the bullets on the left signifies she means business lol. wonderful band IMO.

i love it. leave room for Wyoming!

God bless you my friend and happy Easter right back.

and more acid in your leather! quit jackin with it let it work a couple weeks and go enjoy Easter my friend.

box cases are in book three, they don't specifically show a shotgun case but the techniques are the same.

holy cow those are awesome stamps. I have never seen that brand over here in the states.

the Al stohlman books on case making to start , i think there are three.

i was just thinking the younger folk just snap a picture on their phones to save and share info, it would be good to have something on or near the sign so they could do that. good luck to you sounds like you have a good niche going.
