Hi, I picked up a 15" Bridgewood bws-15a wide belt sander from an estate sale last week. It has been sitting for 15 year and all of the air hose has rotted away. It did not have the manual or schematics. The closest I have been able to find online is a manual for a Powermatic rb-25 on www.ereplacementparts.com. As far as I understand the machines are all similar. But I am hoping to find a closer match. I seems obvious where the hoses start and end but there are some y splitters in the middle that make it confusing. Any advice would be greatly appreciated.
