Thread: Rectangular dust port on Jointer to a 150mm hose

I have recently asked the same question and had the benefit of quite a bit of discussion - see here:

6" Jointer -UPGRADES?

It's pretty clear there's not much (nothing) to be gained from upgrading to 150mm, however I did change the stock outlet to a much neater transition and have 700mm of 100mm flex before the 150PVC begins. I can't say I've noticed any improvement except for ease of connection because I also added magnetic ports, but I'm happy not looking at that awful black stock adapter!

Cheers,

P

Thanks for that. Your transition looks really good.

The numbers Bob posted, may say it isn't needed but I have found that there is still enough dust and chips escaping that it is worth investigating further. There is always some small chips that end up on the infeed table side of the jointer and also on the back side where there is a small gap around the helix head. With the presence of these chips and dust, it makes me think that maybe my particular jointer could benefit from the larger cfm available with the 150mm setup, even if just a little. The fact that we go from a large cross-sectional area to a small one that is almost 5 times smaller and then to just under half, seems like the perfect opportunity to remove the constraint in the middle.

I had one made at a sheetmetal shop, they were glad to do it because it gave the young apprentice a chance to do some geometry, and an interesting job for him. Charged me $100 and it’s perfect.

Here's The one I made for my planer/thick combo after I completely remade the hood but needed a rectangular to round transition.
It's made from SS from a clothes dryer drum.

I see that Bob, and firstly think "wow", then I wonder if I'd have lost an arm or something equally as important if I'd tried to build it, as that stainless sheet sprung open into bits of me inadequately protected!

If only I could get stainless steel printing filament!

I easily cut the stainless with aviator snips. The resulting edge is very safe so it can be easily handled.
