Sewing a Box X Stitch in Webbing & Breaking Strength Formula

A box x stitch, is used when the webbing could be loaded in multiple directions. Stitches are made both parallel and perpendicular to the axis of the webbing, so a load in either direction will be well distributed. Also double rows of stitching at the left and right ends ensure even load distribution along the expected load axis.
This videos also provides the formula for determining how much sewing is required to achieve a desired sewing breaking strength.

I'm about to make a replacement pendant for our dog's car harness, and searched for information on how to sew the webbing we got for the purpose. Of course, Sailrite had this vid up. Thank you!

I wish all sewing tutorials were like this Today we will be discussing the difference between a shirt sleeve, a raglan, and a sports sleeve, specifically why different types of movement require different sleeves. We will calculate the pull on all stitches when arms are raised...

[@IanDorionHD]

Thanks for the video. I would like to point out that you could achieve even better result by adjusting the tension. I can see the knots on the bottom and it should be in between the first and second layer. And it is important to point out the importance of stitch alignment. The weakest spot of you X-Box pattern are the stitch that are outside the square and this is exactly where it break.

[@HondoTrailside]

I remember a time when climbing gear was sold with these splices, and they used two in series on slings. Depends what working loads one is designing for, though.

[@bloodbushcraft2467]

I love @hownottohighline beak testing videos.

[@elmeradams8781]

Did he do the test?

[@mwiltfang4618]

I can understand why you would want to know the breaking strength of your stitching in a sailing situation, and make that less than the breaking strength of the webbing--in order to keep expensive and critical hull anchor points from being ripped out of place, or expensive and critical sails from being shredded. But in applications such as mountaineering or arborist work, I can't think of any situation where you'd want any connections in your rigging to fail before the anchor point. So I'll use your formula to calculate a stitch length that is at least equal to the breaking strength of the material being sewn. Then x 5.

[@SailriteDIY]

Thanks for sharing your thoughts! It's always interesting to consider different applications and their specific requirements when it comes to stitching strength.

[@dragan3290]

I used to see leather nailbags (toolbelt) with saddlery stitching by hand. Double stitching on damaged areas. My nailbags would fall apart in other areas and still I can't push a screwdriver through my stitching! Lol. If I see it stronger? Is that a problem? I'm paranoid! Cheers from Australia

[@pubu2010]

Well done Matt. I assume a longer box "X" would add some extra strength and/or "double" sewing the box "X" would also?

[@SailriteDIY]

Yes, making the box x longer or larger would add extra strength. Sewing another box x under the first would also do the same double the strength.

[@mba2ceo]

@@SailriteDIY plz show image. U mean just another box X closer to the hook ?

[@amoledor]

Can you do this with bartack stitching to figure out the formula? Bartack stitching seems to be stronger than the "x-square" pattern.

We wrote a great blog to calculate the breaking strength. Here is the link: www.sailrite.com/How-to-Sew-Webbing-Loops

[@tleonard410]

do i need a special sewing machine or foot like you have in the video my sewing machine struggles to feed the webbing

[@SailriteDIY]

If your current sewing machine will not feed webbing a walking foot sewing machine would be very helpful in accomplishing that task. This type of foot is mechanical, it can not be simply added to a non-walking foot machine.

For such a nice machine the stitching looked a bit loose..great info tho!!

[@HondoTrailside]

looks can be deceiving, but it looked like the knots didn't bury on the ends. Check 6:18.

[@EricMossthestrongmanexperience]

Does it matter what kind of thread you use?

[@SailriteDIY]

Yes, the thread strength must be used in your calculation, as shown at 1:38min. V-92 Polyester has a thread strength of about 15 lbs.

[@EricMossthestrongmanexperience]

@@SailriteDIY thank you

[@JohnDylan85]

Will the basting tape gum up the sewing machine needle?

[@SailriteDIY]

Basting tapes have a tendency to leave a gum residue on the needle when sewing, especially with light fabrics. Although a well-adjusted machine should not be affected, run the needle through a bar of Ivory soap to help prevent build-up or use a cotton swab with rubbing alcohol to keep the needle clean.

[@JohnDylan85]

is there somewhere I can find the formula in metric ?

[@SailriteDIY]

Simply use an inches to metric calculator on Google.

[@pieterveenders9793]

After running all the calculations and backchecking it against each other I found out that the formula is in fact exactly the same, just replace imperial with metric. So; Stitches per centimeter * thread strength (in kg) * 1,5 = minimum breaking strength (in kg) per cm of stitching.

[@legendarycustomleathers8387]

There's a horrendous high-pitched whine in this video during all VO. It hurts my ears. This can be solved in future productions by running a band pass filter, or at least a low pass filter around 15khz, without detracting from the audio. People with damaged hearing will never notice it, but people with good hearing (and any nearby dogs) will thank you for it.
