Re: Home made CF equipment
Great stuff suggested so far.
A trick for filling the medicine balls, though: fill a big (gallon size) ziplock or some other container with sand (I used a ziplock because it was easy, I guess a rigid container could work with a little more thought) and cut a small hole in it. Small as in it lets out slightly more than a trickle of sand (you want a small stream). Suspend it over the funnel. Instant automated filling. HOW you suspend it is up to you. I had a big cabinet in my garage with holes in each of the shelves, so I just wedged the corner of the ziploc with the hole through it with the ball on the shelf below it. I suppose you could also hang it by the opposite corner.
Those plastic 90 degree bend conduits from Home Depot work wonders as rings.
