This was my first attempt at bulding a saddle. Id like to thank everyone who contributes to the site and thank @JCLINE84 for his help getting me going.

I will add some in progress pics tomorrow along with the material list.

I’m very impressed with this build. I helped a little with some initial measurements but you nailed it on the execution. It’s a very complicated saddle to build even after you know all of the measurements and layout. And you did a heck of a job on it.

Thanks Jaime. Definitely had to think 3 or 4 steps ahead at times and even hand wheel some areas for better control.

And I am super impressed that you are helping someone DIY a saddle you make and sell. Says a ton about you and your character!
 
Here is the list of materials I ordered. I ordered 4 or 5 times more than I needed due to shipping costs. Glad I did, as I am already planning the next saddle to build.

Webbing
Main suspension (1 3/4" Berry compliant webbing): https://www.countrybrookdesign.com/...low-stripes-heavy-nylon-webbing-closeout.html
Leg straps/Molle/Linemans Loops: https://www.amazon.com/Country-Brook-Design-Durable-Webbing/dp/B003ILSW3A?th=1
Panel adjustment webbing: https://www.amazon.com/Strapworks-M...+17338+strap+for+slings&qid=1619357945&sr=8-2

Panels are two layers of 500d cordura with 1 inch grosgrain trimmed

Hardware
Fusion Climb D-Ring: https://doublesteps.com/product/aluminum-d-ring/
Tri-glide for belt: https://austrialpin.net/product/cobra-original-adjustable/
Belt buckle: https://austrialpin.net/product/belt-buckles/
Leg strap attachment/adjustment hardware: https://austrialpin.net/product/belt-buckles/
Leg strap buckles: https://doublesteps.com/product/adf-raptor-1-buckle/
Panel Adjustment: https://www.rockywoods.com/ITW-Nexus-1-Ladderlock-Buckles-Coyote-498

Thread:
Tera 40 to attach panels/grosgrain: https://www.rockywoods.com/Gutermann-TERA-40-Polyester-Thread
V-92 for all webbing: https://www.sailrite.com/Thread-V-92-Polyester-Beige-UV-4oz-1-050-Yds

Sewing Machines:
I am using two Singer 15-91 sewing machines. One is a 1934 and the other is a 1954. I set them up for the different threads so I wouldn't have to adjust tensions throughout the project. These 15-91's impressed the heck out me and had no problem sewing any portion of this saddle. I did run into one spot where the needle was deflecting through 6 layers of material that I had to hand wheel to keep the needle aligned and from hitting the plate

When I first reached out to him for a question I started it with "Not asking to give away any secrets" as I thought no way someone would actually help me make a clone of their saddle. He gave me just enough help on some measurement so I could figure things out from there. I have read it time and time again on here, and now I will say it again - Jaime is a stand up guy.

Makes me want to buy a saddle from him just to support him and god knows I already own too many. :tearsofjoy:
 
Calculations for Load Bearing
I used the following site (which is a must read for anyone sewing webbing) to calculate my stich length for sewing the main suspension together.

The main suspension has a 6000 lb tensile strength. Below are my calculations:

The equation: SPI x Thread Tensile Strength x 1.5 = seam strength per inch. (1.5 is the average loop strength according to sailrite).

I used 8 stiches per inch (SPI) and V-92 tensile strength is 15lbs.

So 8 SPI x 15 lbs x 1.5 = 180 lbs/inch

I decided to match my seam strength to the webbing strength and chose a Minimum Breaking Strength (MBI) if 6000 lbs.

To determine how many inches of sewing I need to reach this MBS I divided my MBS by 180 lbs/inch.

So 6000 / 180 = 33.3 inches. This is how many inches of seam I needed to sew to obtain a MBS of 6000 lbs. It probably ended up being closer to 40 by the time I was done.

I went with a "W" sewing pattern and I recommend using a ruler and some chalk to draw the pattern before you start sewing to ensure you hit the calculated length of stiches to meet your MBS. (It may be hard to see the stitch pattern in the picture as the thread matches the webbing)W Stiches.jpg

How did the singers handle that fold over for the lineman loops? That’s one of the hardest/most dense parts of the saddle in my experience. I’ve had my 1508 stutter with it before.

The singers dont like to run slow. So I had to give the wheel a hand to get it started, but no problems after that. I had a harder time figuring out how to fold and hold it all together. Found out binder clips are worth their weight in gold!

I actually just do the whole thing by hand without clips but I fold the cordura around the webbing then sew down the center to hold it. Then fold and sew the wrapped portion to create the stiff lineman loop.

If you look closely at my loops youll see the stitching to close them is off centered. I sewed a 2 1/4" peice of cordura to the webbing, then folded the cordura over, then the entire thing in half and clipped. I sewed them off center to ensure I caught the cordura in the fold. Your way sounds way easier.
