help with dc problem

elurstej | Posted in General Discussion on December 16, 2002 03:04am

I have been reading this forum for months and now have a problem I hope someone can help me with. I hooked up a 1.5 inch hose to a 4 inch line from my dc so I could hook up my mitersaw. The problem is the blood-curdling whistling sound. Does anyone have any tips on solving this problem? If I shorten or lengthen the 1.5 inch hose will the problem disappear? Thanks everyone.

I'm betting that you used some of that black sump pump tubing that looks like vacuum hose. (Been there done that!) <g>

It has ridges inside that turn it into a whistle with air passage.

Slip into a vacuum cleaner shop. They have the riight stuff for a couple bucks a foot.

Well, it's actually white sump pump hose. So there's no way around the whistle? Thanks for the reply.

I don't think so. I bought a hose from Bosch to hook up to their tools. They use o-rings so it seals great. I think it is similar to what's being described here. The corregations are squared-off and the diameter is fairly small. With the high air flow from my Fein vac it's a real screamer. Altough it's less cumbersome than the Fein hose I don't use it much because of the noise, even with earplugs.John O'Connell - JKO Handcrafted Woodworking

Sears hardware has the larger shop vac hose. That's what I use between my 4" port and my band saw.

Try running the 4" hose all the way to the tool and then using just a reducer. No need for the 1.5" hose at all...

Minimize the length of the smaller hose.

Likely it is the ribbed hose that causes the whistle. I abandoned the 1 1/2'' collection port. It didn't do the job. I'd suggest running 4'' hose to the mitersaw. I have two gates at my miter station. One feeds the 4"flex positioned directly behind the blade. The second pickup is situated further back as a large funnel. Only one of the two gates is opened at any give time but not both at the same time. Alternate opening the two gates to obtain sufficient cleanup.
