I've recently replaced my main wood-damaging machine with a rather more capable beast and need to change my dust extraction system. I'd prefer to use 80mm pipe and fittings beneath the saw and spindle and combine them into 100 or 125mm before going off to the extractor - I can find
80mm flexible hose on t'web but not 80mm elbows, bends or "tee"s. If necessary I'll do the whole lot in 100mm but I will live in hope (for a short time) that some kind soul can point me at a supplier of 80mm fittings ... ?
