static build up in dust shoot11/14
been planing poplar all week, customer buys 13/16, i rip 4s and 8s ,glu up offfalls and plane to 5/8. 1/16,1/16, 1/32,1/32. done .last week no problems 3 different batches of pop. today chip dent no matter what, how big a cut , how fast a speed. tried two different dust collectors. directly to machine with 10 foot hose. an 1150cfm and a 1550. no difference. i swear the chips stick to the wood and the planer with what looks like static cling. but what do i ground to stop it. and why no probs last week ? lower humidity, maybe?
Run a wire from the body of the collector to the body of the planer?
We have no idea how big the planer is and no idea what size the hose is, so can't judge if the air flow is adequate. Cheap corrugated hose can have up to 9 times the restriction of straight wall pipe. Why use 10' of flex when it is right beside the machine? A 6" pipe is always preferred on a big chip generator like a thickness planer. There can also be a wide range of density in different poplar stock. The soft stuff will make a bigger curl.
after reading some of the knowledge base responses , i took a squirt bottle and squiggled a zigzag water squurt on each piece and completely eliminated tge problem. not the best solution ,although I could rig a sponge feed or mist setup. going to try ground next. fl humidity dropped from 85 to 45 percent in the last week. I'm guessing thats why problem occurred quickly
Is the hose itself grounded? i. e. Did you strip/expose a bit of the wire helix inside of the hose and place the hose clamp directly over the bare wire so that it would make contact with the DC and the planer thereby grounding both the hose and machine? Then did you verify continuity from planer to DC with an ohmmeter? This would help eliminate static inside of the hose and also the dust shroud. I know that this was an issue in my shop one time and after I found the grounding issue that also eliminated the problem.
