I’m not big on secrets but I’m also not finished but I will go ahead and post what I have done so far. I have access to all kinds of welders but they are over a hour away so I just used an oxy/acetelyne torch. It’s pretty simple. The tree bracket is a wild edge stepp. @SteppsbyWildEdgeInc you and anyone else are free to build off of this since for step users I think it offers a lot of options including a rifle test and a bow holder. All it took was brazing a 5/16 bushing into the corner of a stepp. It took some playing with to get it where I want for the leveling function to work. Brazed a nut into the v also. I went with. 5/16 on both since I new I had to tap the nut out after heating and I didn’t have a 1/4” tap on hand for the adjuster. I plan to add a small aluminum block to the lower arm about half way down. It will be tapped to 5/16 to allow me to put the bolt back through to tighten everything down for transport and ensure I don’t lose the bolt. Right now as it sits it is 2lbs 1.5oz. I think I can add another bushing for a lower limb bow hanger and stealth strip it and still be under 2.5 lbs. Also as a disclaimer you probably shouldn’t use the step again for climbing. If I do it will turn into my bottom step. If someone is interested I will get a materials list together. Everything but the stepp came from Tractor Supply. I think I’m around a 100 dollar bill all in. I found a button sized level to fit in the top of the plastic handle but have to order 10 to get them. You can save on the handles also. They are 4.99 each but it would be easy to turn a bolt into a thumb screw to save there.
