i'm thinking of running some duct for my shop vac. I have normal dust collector but would like to use the shop vac for the miter saw, sanders, etc. I'm wondering how long of a run is 'too long' and what size pipe to run.
My shop if 16' by 40' and the convenient place to mount it is in one corner. So i can easily see a run going 12' along the short wall, turning the corner and then running a good 20-30'. Is this too long? What size duct would you run...2.5", 4"?
