I bought a used single tower cable trainer.
The plan was to find a second used one and build a cross tower trainer.
I bought a second one only to realize that the newer model had significantly changed ratios.
Long story short, I ended up with a matching set with an extra one left over to sell.
But it had no attachments to go with it.
That led to a giant 'waste' of time. Thinking of every possible, easy to make, DIY cable attachment.
Using stuff I had laying around or that could be purchased with one trip to a thrift store ($10 budget).
Which lead to making them.
Most will work for lat pull down or seated row positions.
Some require welding skills, some don't (drill press, drill, saw, sander and not much more).
All the materials were used, recycled, green sourced, repurposed.
I did not make the fabric ankle straps or cheap plastic hand grips (thrift store).
The buyer was a random guy. Turned out he had former pro weightlifting experience and mentioned carpel tunnel surgery recovery.
The set provides a lot of variety.
Of everything I made, that section of 2x4 with purple paint might have the most potential for a niche market.
Honorable mention for green manufacturing using recycled materials: old ratchet straps, baseball bats and hockey pucks.
The fire hose and rock climbing holds are included in that recycled list, but it needs something extra to ease swapping holds.
That defective 2x4 seems hard to beat in theory.
