Re: Dust collector piping

Interesting.   I had no idea that we have MM in piping in this country, but I guess that could be an issue.  Even trying to connect to the main piping coming out of the Grizzly 3hp cyclone "input" side is very difficult.  Strange.

 

I guess I will have to start designing piping that goes together as easily as "legos".   It just seems very odd to me that as long as piping has been around, there are no easy ways to make connections without a lot of sweat, tears and money.

 

Appreciate everyone's input.  I'll just keep plugging (crimping) away at it.

 

Thanks

Re: Dust collector piping

it's money...

 

a lot pipe is propriatary to it's own...

 

MM to SAE was an example hoping you would unstand what you are up against...

I don't really know if this hard fact but it's only an anology...

 

look to adaptors and bands to hook up to where you want to go...

Re: Dust collector piping

i'll offer a spiral duct tip in return for a flex hose tip. I gave up using crimpers, smaller diameter plastic sleeves, etc. and finally broke down and bought REAL spiral duct fittings. They're a bit pricey, but work perfect (got mine from Wood Werks Supply). Now, I cut the pipe flush, and push it over the fitting, which has a little rubber gasket seal. It doesn't leak, but still comes apart, if required.

Now, here's my flex hose problem. every time I try to slide a piece of flex duct onto a spiral pipe, it turns into a wrestling match. I just have a real struggle slipping flex over spiral duct. Anyone have any ideas?

[ Edited ]

you didn't say which type you have...

 

for plastic flex soak the fitting in hot water 1st

 

metal/plastic, unwind the hose....

 

for metal... slide it onto a crimped pipe end as far as you can get it to go to expand it to a larger dia...

Re: Dust collector piping

Tbe spiral duct is metal, and I've tried two types of flex - plastic with a wire spiral and plastic with a plastic spiral. I'm trying to slide the plastic flex spiral over the metal spiral duct, and then to my tools.

Re: Dust collector piping

IRL you need a take off...

 

Or what is referred to as a concentric reducer...

spiral reinforced hose will expand if you twist it in a screwing motion...

Re: Dust collector piping

I'm with Stick, warm it up first. You could also try a little WD40 on the pipe.
