I just bought two of these type machines from a gym going out of business. My intent is to use one as a lat machine-cum-rower, by cannibalising weights from the other.
My question is: What would be the best approach? They have 40 kg each. Do I extend the stach by welding the "lifting bars" in tandem so that the stack gets taller? The movement range would seem ok. Altenatovely, I could weld tubing to hold olympic weights. That would be a narrow squeeze,though.
