I have a DG-10 dust air blower as in the file image and am having trouble reassembling in the correct order for it to work properly. I have tried Googling with no success. It is only worth a couple of $s and gives no more than barely a weak puff of air when hooked up to the air compressor when new, never the less I would like to now reassemble it correctly. Seems simple enough but after multiple tries it has defeated me so far so I though I would ask instead of wasting more time. Is there a more suitable site where you can ask for home handyman help for maintenance of tools and advice on doing workshop/shed tasks as I am a keen do it your-selfer who will attempt any project?
