I posted this question about the time TheForge got hacked.
I know that there was a question about self closing hinges some 
time ago but I did not save all the info. I would be greatfull if someone
could explain how to build this type of hinge.

Thanks & Forge On !

> could explain how to build this type of hinge.

For a gate which swings both ways and self closes:
	Upper hinge - pintle and eye with a bit extra clearance.
	Lower hinge - two pintles about two inches inside and outside the 
gate, with half eyes.
As the gate swings, one half eye does the work and the other comes off 
its pintle. The greater the spacing between the two pintle the great to 
return forces.

One limitation of this design is that the upper hinge supports the gate.

It can also be used for a gate which swings one way only.

The method that I saw in Wales was that the hinge tubes allowed the gate 
to move vertically about an inch. At the bottom of the gate, about 2 in 
away from the hinge, is a roller with it's axis horizontal to the 
ground. This roller rides on top of a ramp that at it's lowest point 
causes the gate to stay in the closed position. This ramp can be either 
single sided or double sided depending on whether the gate swings only 
one way, or both ways respectively. The ramp is cut into the top of a 
large piece of pipe, as it must be circular to follow the roller as 
it rotates around the hinge.
