Dust collection hose adapters

Could you use pvc approximately the right size and cut it so it can spring open a bit or squeeze down a bit to suit?

I do it the way Terry describes and it works great. I run the end of the PVC pipe into my band saw, making slits about every half inch, running a few inches up the PVC. Then I put a band clamp around the PVC to shrink it, slide it into the coupler, and then duct tape around the PVC if necessary to prevent an air leak through the slits, but normally the slits are pulled shut from compression of sliding into the smaller coupler. The second picture in this article shows a piece of PVC that has been cut in this way for downsizing purposes: http://www.wwgoa.com/articles/projects/-d-o-g-simple-approach-for-dust-collection-ducting/

You can also heat PVC with a heat gun and force it open (or closed) enough to often fit something just a little under/over size. At Pentz’s site they explain doing it with a propane torch as well, but I’m not brave enough to try that.

Sometimes when I look at my DC piping I see a reworked shoe, You know, cobbled?

Aluminum is real easy to work with. You can buy at the hardware store a length of 4” unclosed pipe. You can shape it into a cone, split it, do all kinds of stuff.

Lately I’m working on getting a vintage Craftsman 1/2” shaper hooked up, and the best way to come off the fence was with a plastic gutter downspout elbow, 135o. It’s beautiful.

When you’re doing these kinds of shoe repair, bear in mind that you’re dealing with suction. You don’t have to seal it like it’s under pressure, which is quite a different thing. I have used plastic shrink wrap 3”, which I always have around. A few turns and it’s sealed tight and it comes apart clean.
