A milkman who wanted to overthrow the government because he believed it had been taken over by Jews, has been found guilty on three counts of possessing terror documents.
Nicky Davison, 19, of Annfield Plain, Co Durham, was the co-founder of Aryan Strike Force, an on-line extremist neo-Nazi group.
The jury at Newcastle Crown Court took 50 minutes to convict the teenager.
His father Ian Davison, 41, a disc jockey, earlier admitted six charges, including terrorism and producing a chemical weapon. He was discovered in possession of ricin, which can prove fatal.
During the trial, Andrew Edis QC, prosecuting, said the website was set up to form a group that would be ready to act and fight what they called "ZOG" - Zionist Occupied Government.
When police raided Davison's home, they found online copies of manuals, which gave information about how to make letter-bombs, explosives, detonators, grenades, silencers and poisons.
The two men will both be sentenced at a later date.
