If that's an ABS fitting cutting it off 1 1/2" up from the top of the bottom hub, and installing a new elbow on the vertical stub would fix that, but I certainly wouldn't glue it on.
That would work just fine but use a rubber Fernco coupler to attach the two together. Makes life really easy. I keep a few of these 6", 4" and reducer style ones handy in the shop. They have severed me well and remove the need to glue."There's no hub left to glue to if I cut it off Dan"
Nope. What I said was to cut it off up 1 1/2 above the top of the hub...attach the new one to the stub. But now that you mention it, I can't remember if the OD of the body of a fitting is the same OD as the ID of a hub (ie OD pipe diameter)
Is that a 2 1/2" dia. ? all the drum sanders I have had have a 4" straight up dust port. But as far as the small port goes it is plenty adequate and fits a shop vac.Well I received the new cover from King today and installed it. It only took a few minutes. The angle of the dust fitting on the new cover is very close to where I wanted it. The new cover came quickly and was well packed. King gets an A for customer service. I couldn't have expected anything better from them.
