You know, guys, we could get started locally by getting a 16 pound shot put.
Online they cost less than fifteen bucks...

a 15 pound "fake" hammer could be made from three 5 lb weights bolted into a 50-inch piece of schedule 40 PVC. It's a pound light, but big whoop. Maybe we try that first and move on to the 22 pound hammer, later?

A 25 pound weight for distance could be made from 5, 5 pound weights on a big eye bolt, and a honkin' ring through it.

The 42 pound weight over the bar might be a bit of a challenge, but we could fake it with a 40 pound dumbell. That'll cost $$ though.

I wonder what a 14 foot long, doug fir or hemlock 8 x 8 timber would cost, and if it's even close to 75 pounds. It's a bit small for a caber, since they're usually 16 - 20 feet, but to get started it'd probably work.
