For all around starter out clamps, pipe clamps, when your in need of longer clamps, just buy new pipes. However make sure you get some mean green or greased lightening to degrease the pipes before you get them near the clamps.
When buying alluminum clamps, it’s best to get the pony clamps rather than the harbor freight, which may actually give out under pressure oddly enough.

The best clamps though are the heavy I-beam clamps, when you really need to torque down on something, there’s nothing that will beat them.

The wooden hand screw clamps from harbor freight suffice, they usually go on sale from time to time and you can get them relatively cheaply, if the wood goes bad, just replace.

Face frame clamps are awesome, and well I love them, they reduce the need for me to use nails in face frames which is awesome.
