Dust collector hose....ugh 6"

So i finally put up my "big" cyclone and am now experiencing a headache plumbing it. The pipe isn't the problem(I'm using thin wall sewer and sd35 fittiings), it's the damn hose. I ordered 6" thinking it would actually be 6", but it really isn't. I don't care what they say or who has managed to somehow make it work, It doesn't.
I've melted the pvc OD, tried to expand the hose OD, cut slots in pvc, cut a channel in pvc. None of this is working.

The OD of the PVC is 6.25 and I found a company called Flexaust that has hose in 6.30. The problem is...it isn't cheap... a 25 foot section is 250.00 or 150.00 for 10 feet. Would anyone be interested in splitting some with me? I'll share ALL my knowledge of this dust collecting nightmare with you and probably save you money....

BTW, the 4" hose that I bought actually fits over my 4" fitting.
 
I had the same issue, fortunately mine was out of sight "in the closet" so I used a couple of rolls of duct tape. 2 years later, still good
 
Flex hose & pipe

Randy,

I used this flex hose: http://wynnenv.com/products-page/woodworking_hose/pvc-hose/

I used two different 6" pipes, both of which have the 6.275" OD. To pull the hose over I removed a little of the wire re-inforcement, heated the flex hose with a hair dryer and pulled it over. The removal of the wire isn't absolutely necessary.

I'd also recommend the bridge clamps they sell; they get a great seal.

Okay..Yes SD35 and the thinner walled D2729 are both 6.275. Did you have a hard time getting salesman to understand what 2729 is? I tried 3 Ferguson's and none of them knew. They kept wanting to sell me SD35 pipe, which costs 3X's as much. Notice the calipers aren't even fully closed....

I had a nightmare trying to find the 2729. Should've just bought it from McMaster and been done.

Shit, man, find a plastic fitting that will wedge INTO the 6" pvc and then turn the other end down to go inside your flex tube. You may need to use a plastic floor drain fitting, or some kind of drain clean-out port, or whatever - but there is almost certainly something that serve as a splice. Or - and this may or may not meet your needs - Rockler, Grizzly, and other suppliers sell plastic and/or metal blast gates that are meant to fit inside 6" plastic pipe and 6" flex hose. Use those, or maybe they also have some kind of splice that solves your problem.

You're not the first guy to face this puzzle, and someone out there has almost certainly solved it by now.

The stupid hose can be shoved up into the female part and I suppose fastened. I have 6 inch blast gates coming and I really don't want to McGyver every connection if I can simply replace the hose I have. The real problem is this fricken hose is tool small. The four inch I have is a tight fit, but it fits(although it is going to a DC fitting). I'm fishing for the next 5 days, so my blast gates should be here during that time.


I could certainly reverse the jaws on my chuck and turn some SCH 80 down to the correct ID's and OD's, but at 10-13.00 a foot I may as well buy some hose that Beau says fits.

I hate it when things do not go as planned.....:help: the guys/gals on this site got just about every angle covered.

vac, fittings

if you use the thin white sewer,you need to still use some of the vac. fittings,t's, elbows,& 45's,like what woodcraft carries.i did that with 4 in. and had no problems with the clear vacuum hose.you will still have as much money in the piping as you have in the cyclone,but less headaches,even down the road if you want to add to the system.

I don't plan on using 4 inch very much and Woodcraft has nothing in 6". I don't remember what I paid for my cyclone, but I think around 400.00(it's about 1650.00 new). It was in new shape until it sat outside for 3 years. Thin wall sewer uses SD35 fittings. No offense intended, but it's really easy to overspend on fittings and pipe if you buy into some of the hype. There is even some 6 inch SD35 pipe here for super cheap(surplus) that I could have purchased for less than the 2729, but it's heavier and I didn't feel like driving to go get it. I would have had to cut the 20 footers as well. Not a big deal, but the pipe I got here was local. That SD35 was still up on Craigslist last time I checked.

I have about 350.00 tied up in pipe, hose and fittings .

That includes:

30 ft 6 inch
2 wyes
8 inch to 6 inch adaptor
3 6 inch blast gates
1 6 inch to 4 inch(x2) pipe with blast gates.
10 feet of hose

BTW, the Grizzly seems to pull as much air, with 2 six inch blast gates open, as my Jet does.

Sent you a PM Sir...
 
Is the pipe 6.25 or the hose? I'm confused. If it's the piping that is too large for the hose, then the fix is simple.

The pipe is 6.25 wire reinforced. I'm interested in the simple fix. Note that the hose I was sent is about 5.70.

You show a white PVC coming out of your cyclone. You then show the white 5.70 PVC inserted into the wire plastic tube. Now you're saying 6.25 wire reinforced pipe with 5.70 hose. I'm totally lost here. You're calling pipe, hose and hose, pipe and visa versa so I'm lost. And yes the fix is simple. However, I need to know what the heck you're talking about.

Is the 5.70 white PVC? Is the 6.25 the wire reinforced plastic tubing?

If so, here's what you need.

Unfortunately, you'll have some collection inside the hose where the two meet but there is no way around that.

Hope this helps.
 
You may also have some luck finding the adaptors at one of the local truck repair shops. When I say truck repair, I am referring to big rigs. You can pick up exhaust piping, reducers, expanders and everything in between for 6", as it is a common size for exhaust. Chuck it up in the lathe if you have to and make whatever you need for reducers.

Aloha

Look at the bottom of the PVC, in the pic where it measures 5.70, and you'll see where I cut it to fit inside. You will also see that it overlaps quite a bit. What isn't apparent is that I took about .50 and inch off before that...
 
Randy,

You're cutting pipe, trying to fit larger tube on a smaller pipe, etc. This is not conducive to an efficient dust collection system. You're going to lose a lot of suction so here's my suggestion: scrap it all and buy the correct products to build a performance dust system that will work as it should without great loss of power/suction and build up inside the pipes causing blockages. Cobbling this together is just asking for more headaches down the road. But then again, what do I know about this sort of thing and especially saving money. Good luck.

Perhaps you can not cut it and then use a 7-6 reducer.
 
You know those chucks on your Bison chucks are reversible.
Can easily hold 6-7" tubes .
A few passes ought to do it.

Or just buy that reducer.
