LOL Better move to higher ground, that should reduce your headache!

Here you go for all the atmospheric pressure measurements you'll ever want! https://en.wikipedia.org/wiki/Atmospheric_pressure Quoted from Wikipedia: The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050 mbar (105 kPa; 31 inHg), with record highs close to 1085 mbar (108.5 kPa; 32.0 inHg). The lowest measurable sea-level pressure is found at the centers of tropical cyclones and tornadoes, with a record low of 870 mbar (87 kPa; 26 inHg). https://www.engineeringtoolbox.com/air-altitude-pressure-d_462.html for altitude versus atmospheric pressure calculations and table. For conversions 1 psi = 6.8954 kPa. So the record high in Siberia of 108.5 kPa = 15.74 psia while the lowest 87 kPa = 12.62 psia Calgary AB atmospheric pressure runs around 88 kPa (12.77 psia). This is uncorrected to sea level, so not the same as you will see used by the weather office, but the same as used to calibrate airplane altimeters. Weather office currently shows 101 kPa here. I could tell you a story about an engineering firm doing tests for designing an electrostatic precipitator, but we are already way off topic.

or 14.6954 if you want a couple more decimal places.

That would be 30" Hg (mercury) vacuum. Atmospheric pressure is nominal 14.7 psia. So you can't pull a vacuum exceeding that number. Not that this makes any difference to what you are doing. Just clarifying actual numbers.

Moved to Leather Sewing Machines. If you search this forum, you might find more info.

@shes2funky4u You can try searching through https://web.archive.org for the catalogue if that is what you are looking for. They have archived many websites. You might even be able to find Wyomingslick's blog before he deleted his entries.

Wyomingslick became disaffected and no longer visits LW. Last visited October 10, 2015. He deleted his blog posts. https://leatherworker.net/forum/blogs/entry/295-what-is-going-on-i-have-deleted-all-of-my-blog-entries/

Here is a supplier of lubricated bonded nylon thread. If you search the Leather Sewing Machine forum, you will find several posts on lubricated thread.

According to his IP address, he is in the New Orleans, Louisiana, 70119 area. @BeltBro Please refine your location in your profile to at least get down to the state. People would like to know if you are within driving distance for example.

@NoelMc Moved your post to leather sewing machines. There are lots of posts in this forum about different machines. Also as mentioned above, look through the thread by Wiz. "The Type Of Sewing Machine You Need To Sew Leather" Lots of very knowledgeable people frequent this forum.

Once you figure out what caused the stain, best option might be to use it to stain the whole cap.

Looks like it may have been in contact with a leaky bottle of something. Ask what it was packed with and how.
