BTC chair
Lying BTC was only possible for me on a stiff board. It still wasn’t very good, and not a lot do down there either. I gave it up and made a BTC chair.
black: chair
blue: hanger; s-hooks
red: cord
brown: plank
purple & pink: smooth wheels
green: weight
i didn’t butcher a chair for this; I made two cushioned seats, hole in the between obviously. I attached the while plank/wheel arrangement to the chair with cargo fasteners (I don’t know the English word for them). The plank is actually 3 planks, describing an ‘H’ turned 90 degrees. The horizontal planks attach to the chair; the wheels to the vertical.
Actually, for maxed out BTC angle, the lower wheel might best be positioned a bit higher relative to the floor than it appears on the sketch. That way there’s no need at all to scoot down in the chair. I spent many months on BTC (I might again too), and being able to sit with a straight back anywhere I choose is well worth the small effort to make an arrangement such as this.
I’ll just recommend using good, smooth wheels. $5 instead of $2 for inertia prone small wheels. Really makes a difference; especially when using two. Other than that, you can probably scramble up the parts within walking radius from home, unless you reside in the hills.
It’s not difficult at all to make. A drill helps. Anyone want to try it, you’re welcome with questions of course.
