Ok Marcel. Here are some pics of my dust collector and separator. The separator is a 30 gallon fiber barrel. It is mounted to the dust collector on a shop made stand with wheels so it can move around with the dust collector. The hoses are mounted to the lid with plumbing fittings. I used toilet flanges that are bolted to the lid with silicone in between. The separator collects about 95% of all dust and debris. Very little debris goes through the impeller.
