splint you dust pig !!!!! 😁 i dont why so many are having issues with electro static shock or dust build up ? ive just used plain ol pvc drain pipe. cheap and easy to assemble. no problems in the last 30 years. that copper mesh sounds, yeah expensive and ive never heard of being used before ?

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.
