So I have an old Mirka 650 DA sander. Pnumatic. I accquired it used, without attatctratchments. Currently I have a bit of inch wire wound suction hose shoved onto the dust port. This hose is supposed to be for sucking up liquids. It's heavy, inflexible etc. It's not the tool for the job! Do I - A) buy one of mirka's many different hoses (which one, I'm not sure I know) at a minimum of £40 it seems. Or B) buy some of that black spiral stuff (or somthing else - suggestions welcome!) off eBay for a fraction of the cost and run with that. In truth, if there was an obvious offering from Mirka id probably just get that, but I find their products just as confusing, so it's not like I can just buy an overpriced bit of hose and the job is done anyway! Thank you.
