I am in a new shop and I am ready to "pipe" my dust collection system. This wasn't an issue in my older shop, which was small and I simply drug the DC hose to the various machines. I have an Oneida Mini Gorilla and I have been very pleased with its performance. The way I have configured my shop and the various dust producing tools, I will not be dealing with long runs, so I am feeling fairly confident that the Mini Gorilla will be sufficient for my needs. That said, the problem I am having is finding a fitting to work with the Mini G; it has a 5" inlet which I would like to fit with either a 5"x5" wye or a 5"x4" wye. (If I use a 5"x5" wye, I would then reduce it with a 5"x4" reducer). Does anyone have a recommendation where I should look to find either one of these fittings? Thank you!
