My first stand was a Baker, complete with hand climber. A few practice climbs in the back yard quickly showed a few short comings.
First, while climbing, the platform could easily fall as my weight shifted to the hand climber. I put 1/4" x 4' nylon ropes on each side to connect the platform to the hand climber. (Still use that for security on my newer stands)
Next, there was no way I could stand still for long on that thing so I rigged a nylon fabric "sling" seat to the hand climber. Not an easy chair but it worked and didn't add much weight.
Carrying it was going to be a problem. I found a torn up back pack at a yard sell for buck, bought it and attached the straps to the bottom of the platform. Instant easy carry and reasonably comfortable too.
Saw it would be easy to lose those crititcal wing nuts. I drilled a small hole in one wing of each and tied a length of 60# fishing mono to secure them to the frame. And then added one spare nut and bolt to the frame, just in case!
The base didn't grip the tree very well, especially if I stood near the tree, because that bit of alum blade just didn't dig in very well. I replaced the blade with a couple of sharp "spikes" made of 1 1/2" heavy alum angle and it then held quite well.
Modified, I used that thing for several years, safely, but it was still a pain to set up (slow), especially in the dark, and somewhat heavier than I wanted, so eventually I got a new stand. But my old Baker is still in the attic, ready for use if needed!
