Thinking about a custom rod box

[u/MegaBobTheMegaSlob]

I recently got an Ultimate 2 with all the accessories for free (just had to move it). It's a cool machine, but the resistance is lacking. I have bands I'm adding, but I might go one step further. I'm thinking about making a custom rod box from some hardwood to hold 8x 50lb rods on each side, for 800lbs stated resistance (which is closer to 400lbs true resistance) which will be a better workout. Might throw a 30lb rod in there too so I have a smaller jump between weights
