temporary dust pipe4/25
We need to hook up a dust collector that would work for a couple of months.
We don't have the floorspace in this vicinity to put a roll around dust collector here. i was thinking instead to tap into the Dustec.
Is there any downside to doing this in ABS or PVC pipe? We need about a 4 inch pipe and it needs to travel about 20 feet.
Any problems with doing this in plastic?
Some may say the downside is the static electricity that's generated by fast moving dust and chips in plastic pipe, and some may say it can be mitigated by running a grounded wire inside the pipe. If it were me, I'd not take a chance and rather buy a 20' piece of spiral pipe from my local HVAC company.
Even the Mythbusters tried to create a static spark in PVC pipe, and couldn't. I've used 4" drain and sewer PVC pipe in my home shop. It has a bell end, so easy to make up. Works fine. Now in a commercial shop, you have the insurance man to appease. "Just how lucky a fellar are ya?"
Probably be easier to do in metal, though more expensive too. You can buy a saddle type connector which allows you to just cut out a section, screw on the new saddle, and run your new pipe off. I did this for a shaper I added after I already had the system in place and it worked flawlessly.
I'd just buy two pieces of 5" PVC, thin stuff, and hook it up. (you'll get better air draw thru 20' of 5" rather than 4") The bell ends work if in the right place. If not I'd use rubber sewer boots. Or, HVAC pipe comes in 5' sections, is cheep and easily obtained. HD would have it. When you don't need it you haven't invested much.
If you don't have an insurance Co. to deal with PVC works, forget the wire, it's of no value. Spiral duct from a HVA company is readily available and not all that expensive.
