I have a few projects I want to do. One of them involves hanging a sizable weight from a wooden dowel. Does anyone know where I can find a chart that shows how much weight one can support?
I also want to build something where the weight will be on the end.
 
What you are asking requires a whole lot more detail.
 
I agree with the above post but here is what you will need to know.

The compression strength of air-dry wood is about half of the corresponding tensilestrength. The shearing strength of wood is 10-15% of its tensile strength in the direction of the grain. Shearing strength is weakened by knots and faults and cracks that appear in the wood.

Ok. I want to hang some weight in the middle of it, about 200--300 lbs. I want it to be 8 feet long of a span.

For the other thing, supporting about the same weight.
 
You'll be better off wrapping a 1" or 1-1/2" piece of pipe in a phenolic material, than a 3 to 4" fence rail.

I need a better description of the other thing.
 
Go out in the woods and cut down a 2-2.5” dia white oak sapling about 6 inches longer than you need. Bring it back to your work shop and carefully take the bark off with a draw knife. Apply wax to both cut ends and tuck it up in the rafters of the shop for a couple years to slowly dry. Take it down and remove some from each end to get the length you need and then apply raw linseed oil over a period of a few weeks so it soaks well into the wood. Hang it up and put your load on it. Simple as that. Every year I would give it a rub down with more linseed oil and it should last several hundred years. :)
 
If you really want/have to use wood, make sure the grain runs vertically (when looking at the end grain). A 2x6 (edge down) should hold. 2x8 even better. If it has to be round, use a telephone pole. If you use a telephone pole, you can orient the grain any way you like.

PS: No guarantees. But, I use 2x3 boards on edge (approx 7 ft long) across the ceiling of the garage to lift the rear hatch off of the car. (150 lbs ?)
