Try leather tape for basting, also for stitching. https://www.wawak.com/Bag-Construction/Basting-Tape/super-strong-double-sided-vinylleather-basting-tape-clear/?sku=TPE15 Note different widths available. 1/8" to 1". They ship to Canada! Have ordered items from them time to time and have not had any problems with shipping. Pre-cleared customs.

Moved. Thanks for catching this Uwe.

This is a very old thread from 2011, your post adds nothing useful to its content. Please start a new thread in Leather Sewing Machines

You might like to cross post this in the leather sewing machines forum. That's where the machine guys hang out.

A book referred to in the post above - W C Double's 1960 book The Design and Construction of Handbags is available as a PDF from this location https://vdoc.pub/download/design-and-construction-of-handbags-2o03sd59jrbg for anyone who might be interested.

Anyone looking for this book can download it from https://vdoc.pub/download/design-and-construction-of-handbags-2o03sd59jrbg

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.

@ddiuni Moved your post to Leather Sewing Machines, You'll get more response here.

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.
