Band Saw Dust Chute Issue

[jsburger]

Fittings have 'male' and 'female' ends. The elbow has one each.

Actually they are 2 1/4" id/od. The hose is male(2 1/4" od). The saw guard is female (2 1/4" id[+ a smidgen]). My 'add on' bandsaw port is female.

The elbow allows the hose to exit away from the table etc.

The elbow 'female' end also has a 2 1/2" od and a fixed stop 'ring'.

The saw guard 'female' end has a 2 1/2" od.

If you are slipping the hose 'over' the saw guard port your hose is not the size intended.

However, the female end of an elbow(ss issue) should provide the same od as the saw guard.

I do not have a bandsaw with the molded in adapter cover. If yours is, share with us the id/od of the port.

The issue here is the difference in diameter of the hose itself and the diameter of the fittings that are used with the hose. The hose is in fact 2 1/2" inside diameter. Hence the name 2 1/2" DC hose and fittings. If you put a screw on plastic end (male or female) on it you can use all the other DC fittings. The plastic fittings have IDs and ODs of roughly 2 5/16" for the female and male ends. The label on the fittings I got from Woodcraft actually says 2 1/4". The OD of the female end of the fittings is 2 15/32". The 2 1/2" dust hose will fit over that end but a clamp is needed to hold it in place. This can all be seen in the picture. The SS fittings are the same size as the Woodcraft fittings. In the picture the elbow on the right is SS and the coupler and the elbow on the left are Woodcraft.

As for the blade guard, as you say it is a female fitting so any male fitting will fit inside. It's inside diameter is 2 5/16. Also as above with the outside diameter of a female fitting a 2/12" DC hose fits just fine. Actually the plastic of the blade guard is thicker than the DC fittings so it's OD is actually 2 1/2" and not 2 15/32". The hose fits perfectly on it.

Now for the band saw cover. The molded in DC port is female and the ID is the same as all the other female DC fittings, 2 5/16". If you look at the picture the wall thickness is much thicker than standard DC fittings. It is actually 2 5/8" OD so a 2 1/2" DC hose will not fit. That port is designed to accept a male DC fitting only. algale and charlese indicate that the DC hose will fit inside. I don't see how that is possible given the dimensions above. The OD of a 2 1/2" DC hose is roughly 2 5/8" over the spiral wire. There is no way that will fit inside the band saw DC port at 2 5/16" ID. I did try BTW.

The bottom line is that the SS band saw DC port is a standard female DC fitting but the OD is non standard so a hose will not fit over it.

In my experience the shopsmith dust hose fits INTO the dust chute not over it.

That is my experience with both the band saw and the lower saw guard, at least when using Shopsmith supplied dust collection hoses and fittings.

Question for rmbishow: are you using Shopsmith hoses and fittings or some other brand?

I am using a semi-clear 2 1/2" x 8' hose from Woodcraft. The hose does fit (albeit rather snuggly) on the lower saw dust port, but is impossible to fit over the band saw port. If one end of the SS elbow is female and the other is male, that sounds like it might resolve my issue (if the male end is more narrow than the existing band saw port). I would have hoped to avoid a 90 degree angle, as I understand that such angle can reduce the DC efficiency. I wonder if Woodcraft has a straight male/female connector? Might have to check. Thanks all for the thoughtful responses. Rick

Hi Rick,

Yes the hose will fit the blade guard but not the band saw. The OD of the blade guard is 2 1/2" the same as the ID of the hose. See my other post. There are two solutions. Get a screw in male end for your hose and then it will plug right in. With the hose coming straight out and down to the floor you still have a 90 degree bend. The other option is an elbow. The male end fits the band saw and the hose will fit over the female end with a clamp and hang straight down. Either way you have a 90 degree bend.

John,

Good point. 90 degrees either way! However, just to pursue the point, if I use the elbow, the hose will still fall to the floor and then I'll have two 90 degree bends Honestly, thanks for the explanation. Rick

OK, lets try this again. Either way you have two bends. The one at the floor and the one at the band saw dust port. With the straight adapter you will still have a 90 degree bend in the hose at the saw when the hose falls to the floor. With the elbow you have the bend at the saw via the elbow but no bend in the hose at the saw.

I tried to read all that is posted here on this subject and make it all fit together but I got confused. To eliminate my confusion, I just had to go to the shop. This is what I found there. My band saw (the one with a DC port) and my hose fittings are quite compatible. This same hose, though not pictured here fits on the lower saw guard just as well.

I have some hoses from Woodcraft (not shown here) and they work (sorta) but they do not really fit together like one would hope.

Yes, I agree it is a bit confusing. Your hoses fit as expected because you have the screw on plastic male fittings on the end as I do. The OP rmbishow does not have that fitting on the end. He is trying to hook up the hose without it. It works fine on the saw guard but not the band saw.

A plain hose with out the end will fit over the female end of the elbow in your picture. The saw guard is also female so a plain hose fits over the outside of it also. If you have the screw in adapted on the hose that makes it male and it fit inside both ports. The problem is that the OD of the band saw port is not standard and a plain hose will not fit over it like it does on the saw guard which has standard dimensions.

I hope this helps.

Thank you. It helps.

In my opinion, there is no problem unless one tries do do something not originally intended. The port on the band saw was never intended to accept a female hose over the coupling. It is designed to be used as shown in my images (and others) here on the forum.

Yup, that is exactly how I see it also.

Thank you both for your kindness. You have explained an issue that had confounded me. I understand it now and I have a solution to what was not a problem as much as a reflection of my inexperience. Rick

The fact that 2 1/2" hoses have fittings that are 2 5/16"(+-) adds greatly to the confusion.
