Rookie diy saddle

[Homebrew454]

I think you need to take a big step back and do some thorough research instead of plowing ahead with your bow case idea. Honestly man the path you’re on is a great way to end up hurt or worse. Speedy stitching a few box stitches will not save your life neither will speedy stitched leg loops. WHAT YOU ARE DOING IS VERY DANGEROUS. There are lots of great resources for this stuff on this site. Take your time and work it out. You seem like an industrious guy, this is something you have to do carefully.

I agree with this... Also please read my earlier post about Sailrite's webbing tests. I am concerned about a single boxstitch being able to hold weight during a fall or even holding your weight at height. If you have any questions, please feel to post.

I'm not certain I would trust the speedy stitcher for life support. You could maybe check for some place to sew it for you. Cobbler? Vinyl, leather repair, etc. Most of us who make our own saddles use industrial sewing machines with proper stitching pattern and stitches.

Thanks for the Sailrite link. I have been thinking of sewing a seat belt webbing saddle but want to make sure I know the proper stitches before I trust my life to one I have sewn. I would only use it at ground level or with a RCH at first. I thought any stitch that can be done with a machine can be done with the speedy stitcher only slower. Is that not true? I thought they are the same stitch.

If you are going to sew life saving or weight bearing equipment it is best to use a industrial machine or stitch it the old way by hand(alot slower) just make sure you are sure of your stitching pattern and your thread is of appropriate strengths!

I have used the Speedy stitcher to sew a few non-life support things. I have been using 100 lb test UHMWPE using the lock stitch recommended by the awl manufacturer. I have about 40 stitches in one thing I sewed so I figure 100lbs per stitch which I downrated due to the two threads crossing in the fabric. If this estimate is reasonable it should not pull out until around 4000 lbs.

I think that looks OK but rock climbing harnesses have a strong waist belt that will not go over your hip bones or your ribcage when properly adjusted. This is the fall protection. The leg loops or in this case the saddle are only for comfort.

This does not inspire confidence. Some improvements, but I am not sure you should proceed in this manner.

What is the strength rating of the thread you are using? How many stitches did you put in? Therefore what is the strength of that fabric weld?

Also how much overlap on the webbing onto itself?

With my Juki I can control how many or how few stitches there are per inch. I know the strength of my thread based upon manufacturing tests. I can therefore plug it into the formula on the Sailrite link. I'm not familiar with the speedy stitcher to know much about it so I will defer to others with more experience.

As far as I know there's only 1 stitch in the speedy stitcher instruction manual

The speedy stitcher makes lock stitches similar to a machine. Speedy? Not so much! Great tool to have though. The drawback is that the needle it comes with has got a sharp edge, made for piercing leather. So I don’t like it so much on fabric. I use a denim needle instead and a different thread.

It looks cool but I'm a sucker for that old Trebark looking camo. Would've spaced the straps out a little more front to back and added a couple supports between. Maybe use this as a mock up and take the other part of the case and straps to a seamstress just so it's for sure able to handle a load? Have you looked into endless loop slings? With 1 you could do what you're trying to accomplish, with 3 you'd have something you couldn't fall through if the bow case gave way. Then you could just sew your case to the slings.

Lol that bad?? I’ve tried it out twice. No higher than 10 feet but but I was honestly pretty impressed. It’s pretty comfortable and seems strong enough

Not to derail: but since the speedy stitcher is general purpose and partly for leather work, I believe that the needle has sharpened edges that will often cut fibers in your material being sewed instead of pushing them to the side. A proper sewing machine needle that is not cutting can be using in the speedy stitcher, from what I have read. Or you could perhaps file the end and edges until it works similarly.

I read about this downfall of this use of the speedy stitcher (on a hammock forum) and then saw the same in webbing I had sewed. After I removed some stitches, I looked at the webbing closely with a magnifying glass and the webbing had many cuts the size of the large awl. If you sew enough on a piece of webbing, then you have potentially cut many fibers in a haphazardly dispersed pattern. So the more stitches you place in order to strengthen the seam, the more you weaken the underlying material.

I'm writing this for the possible benefit of the OP and also others that mentioned the speedy stitcher for life support.

I used it to sew lineman's loops on a Petzl Gym harness and after my discovery I have retired that setup.

seems strong enough

Just because the saddle will hold you while sitting in it doesn't mean it will hold you in even a short fall where several hundreds or even thousand lbs of force can be generated. I think it's very likely that if you put 200 lbs in that saddle and dropped it one foot the single box stitch holding the webbing together would come apart.

Please don't take that chance. A rock climbing harness is cheap and it might save your life.

I just can’t state enough what a bad idea it is to hunt from this thing. Not to be a d*** but dude, this isn’t something I could get off the ground in

If you can afford a speedy stitcher, then you can afford something from this search:

cheap rock climbing harness - Google Search

www.google.com

I don't think we've gotten into your bridge, tether, carabiners, and the knots you are using. Those are of course just as important. Do you have some climb spec rope and carabiners and are you familiar with proper knots to use?

Heavy duty ball point machine needles work well in the sewing awl for this purpose.
