Tree Swing Between Pines

Worthaug said:
I can't stand overkill! First of all, it is not at all necessary to drill at an angle for two reasons, 1. The eye bolt is strong enough to withstand any force generated by a person swinging (go outside an look at an angled guy line on a power pole and note the orientation of the eye anchor bolt in the pine pole...) 2. The drill bit is more effective across the grain. (Use and auger bit and a cordless drill! Duh)
Also, all you need is a second nut, then peen the threads. Skip the shackle and put the thimble directly on the eye of the main eye bolt.

I agree that it is not necessary to drill at an angle. These bolts have breaking strengths in the 10s of thousands of pounds. On this installation I drilled through the trunks at an angle because the forged eye bolts I purchased were too long. I have since gotten better at estimating trunk diameter from DBH (and when possible I just climb and take an actual measurement), but if any of you have tips or equations you use for estimating trunk diameter at a certain height above ground I'd love to hear about it.

Like the hadware.. the epoxy is way overkill though...nnice ride

Sure the epoxy is overkill, but it costs less than $1 takes less than 2 minutes to apply and makes the parents happy. Can't argue with that. I never tried peening the threads as suggested by Reed, but I'm sure that would fulfill the same purpose.

I've been a long time lurker on Tree Buzz and figured now is the best time as any to say Hi. I've gotten lots of great ideas and information from y'all so thanks for that! I'm a scientist by training and am drawn to tree climbing because of my love of the outdoors. I also like the physics and engineering of tree climbing and tree work and that seems to be second nature for all of you. I'm the owner of Piedmont Tree Climbing, which is a side venture for me. I run public rec climbs, rescue cats/drones/etc, and install tree swings -- anything I can do as an excuse to climb trees.

Thank you for no longer being a lurker, that's creepy.

Checking out Patrick's Triple Tuck splice, I not so sure I'd let him do my splicing.

The video Brocky is alluding to is this one:
. I haven't been splicing for as long as y'all have so if you have any suggestions for how to do it better I'm all ears. That's why I posted the video - to get feedback and maybe help someone who is just starting out. The method I'm following in the video is the locked stitch single braid eye splice from New England Rope's Splice Guide: http://www.teufelberger.com/fileadmin/Teufelberger/SplicingGuides/Full_Splicing_Guide.pdf
 
Welcome Patrick, I was concerned about the spacing of your tucks, the one around the thimble could possibly open and come off. The splice in your video is called a brummel because just the tail passes through the rope. It can become a locked brummel if you pass the tail through the rope and tuck the rope through the tail, spacing them two strands apart.
 
What’s up all, I’m new to the group and will take the advice not to “lurk” lol. I’ve gotten some great ideas and solutions from the folks in this forum.

PBrant - your YouTube videos inspired me to research SRT a few months ago. Now I love climbing and setup a couple 40 foot swings and a zip line for my kids. So much potential for fun with trees.
