I recently picked up a new dust collector for my shop. It is the 2HP unit from HF. I have three shapers that I want to hook it up to. They are the Grizzly G1035, the Grizzly G1026, and the last one is a smaller unit that used to be sold by Grizzly, similar to the shaper that.HF sells. The problem is that the factory dust ports on the Grizzly’s are 3”, and I can’t find any 3” hose. I am not sure what would be the best way to hook up this HF 2HP dust collector to my three shapers with their 3” dust ports. Short of building my own enclosure around the cutters and fence, what are my options here? Note that this dust collector is for hookimg up to these 3 shapers only. It will be stationary.

4” hose is a std size and came with the HF DC. Grizzly has a 4”x3” reducer. Search LJ’s, there are many DC threads, and a lot concerning the HF DC. The plastic hose with that DC builds annoying but not dangerous static – it will raise the hair on your arm and zap you. There is clear hose with steel wire support available, I think HF has it. Bond the wire to the DC ground wire and no more static.
