New saddle.

Yes, I agree. Here's a few questions/comments from looking at your pictures:
1. It looks like you have about 3" of overlap where your 2" webbing comes together to form the main support chassis. It is sewn in a Box-X style with approximately 6 stitches per inch. I don't know what kind of thread you are using, but if you do a strength calculation on this seam, I think you'll see it's WAY under what you'd want to support someone's life in a fall situation. In my opinion, you should be shooting for 5000-6000 pounds. My calculation on your seam only based on the pic and some educated guessing on materials is way under that.
2. The lineman's loops do not look very rigid. It is very hard to clip into floppy lineman's loops one-handed while clinging to a tree 20' up.
3. I don't feel comfortable with the amount of stitching holding the lineman's webbing to the chassis. Especially on the top. Because of the direction that the lineman's loops are typically pulled, they probably won't have a problem under normal use. But what about in a fall situation?

If you look at the way the commercial manufacturers put their saddles together, you'll see they put a lot more stitching and strength in these key areas. Nobody wants a saddle failure to cost someone their life or livelihood.

Sorry, not trying to be a jerk but this saddle doesn't meet what I would consider minimum safety requirements and it looks like you are gearing up to sell these to potential saddle newbies who don't know this stuff. I just don't want anyone to get hurt.

These are not for sale. It would be nice. But there not their yet. Still working on them. This is just one I’ve made. Have a lot of them done.

I would be careful selling for multiple reasons. First is I am unsure of the Tex thread (size you’re using) it looks like maybe 92 but I can’t tell. Your stitches are set around 6 spi which isn’t bad, it spreads the load a little better but then you need way more stitches to achieve strengths required in case of a fall or for long term weight. The over lap box x at the top looks like it’s 1.5 to 2.5 inches so your connections strength will be less than 2000 lbs. also with the way your linesman loops are top to bottom, it’s a great idea but I’d have a patent search by a professional done before selling that because there are patents pending from other companies for that design. Otherwise you end up paying royalties to someone. The lineman’s loops look a little floppy too. Maybe sew some thicker webbing inside of them to stiffen them up. Just my two cents. Good luck with this endeavor.

I agree with everything you said because we do not know the breaking strength of the thread he chose. And a single box x isn’t known to be all that strong. But Hawk did their saddle that same way, a single box x across the top because it’s a loop and is sewn into other materials to split the strength. Personally I would want the stitching to be a minimum of 3600 lbs break strength or higher (I personally shoot for 5400 lbs) However if it’s Tex 92 or bigger, he had the top row of linesman loop sewn in with anywhere from 1150 to 2000 lbs into the webbing with a loop configuration and plenty of stitching x’s on the bottom. By making this a loop top to bottom he has increased the strength by 1.5 times the weak point so his linesman loops should be fine as long as a large enough thread was used. The max force allowable for the human body to sustain is 1800 lbs per ANSI so 1150 (or higher) x 1.5 would be almost above that thresh hold and the weight would be split between the top and bottom stitching. My larger worry would be the waist safety belt which is not loop it is sewn in on the top only which means if you had a fall straight down or a fall backwards (resulting in being upside down) the belt wouldn’t have enough strength to hold you to the harness. Yes I realize that the saddle provides squeeze and it would be unlikely to fall through it because we all saw the you tube video about falling in a saddle. But notice no one drops the dummy upside down in the TMA test site videos without the waist belt attached! There is a reason for that. The waist belt is designed to keep you in the saddle, this is especially important if you fall while using lineman’s loops and a rope while ascending.

Let me know what you think. I’ll be testing this week

Thing looks pretty light-weight from over here. Mesh for breathability too, help keep that swampbutt away.
 
So far comfort is great. Being it’s lighter it’s more comfortable. Bridge loops are longer. Helps with hip pinch. I one stick so that’s the most important to me. Being able to adjust that bridge is everything.
