It took a lot of time to finalize with the design changes. The idea behind getting all holes drilled at once I can later on replace parts easily and won't have to touch the rack base (and aesthetics
). I added the pulley mechanism later on once I was confident. The pipes used are 3x3 10 gauge with 20mm holes spaced at every 2". I might change the functional weight slides with selectorized weight stack at some point but this is serving me well. If you plan to get it done yourself, find someone who can laser cut the holes instead of drilling.
If you want to buy perforated pipes, you can have a look at

But this is going to cost you a lot.
