Thanks for the heads up but I'm a little curious about one thing. If this unit is a refurbished unit, why under "product condition" does it state that the unit is untested? Seems only logical that if something is being refurbished it should have to pass some kind of a test, even if its just plugging it in to see if it runs.[] I bid $.02.

Ya I thought that too.. Plus looking at his other stuff. Who knows. I suppose there are deals to be had on Ebay. I think most of the time not. That's IMHO.

Please, do not forget to tip them dealers!

Nowhere on the page does it say refurbished.
In the warranty they say they stand behind it. I guess that means they guarantee it's untested.

They have a bunch of HF stuff on their item list. Maybe HF just sells their returns in bulk rather than try to repair or test them. In that case its probably a crapshoot of a crapshoot. Considering its probably a $30-40 shipping charge on 145 lbs - shipping cost not disclosed - I rate it a risky proposition even tho its only $51 with 20 hours left.

If your only tool is a hammer, you tend to treat all problems as if they were nails.

The final price on it was $100.00. Not much of a deal if you ask me.

You have scrimped and saved for years for the $10,000 buy-in at the World Series of Poker. On the very first hand, you are dealt pocket aces. Two seats ahead of you, the player raises all in. It's your turn to act, what do you do?

There was another DC for sale - Jet DC650 missing bags (and probably the clamps and rod support). I think it went for $100, not a great deal either considering a set of bags and hardware would be probably $75 and shipping for 100+ pounds in the 25-30 range and not to mention it was an oder unit - blue - when did Jet change its color scheme, about 4 years ago? And the current DC650 is about $200 new.

Dust collection

Have any of you guys and gals given any thought to discharging your dust to the outside of your shop?

Back in my car/gearhead days,I had a used blower motor and fan that I got from a laundra-mat, and used it for body work. I got a dryer flange and put it through the back wall of my garage. It work very nice for the bondo dust that I had created.

I'm thinking of doing the same thing now that I'm into wood working, by coupling up a hose and a 55 gallon drum to the dryer fitting.

I'm gonna play around with this and will post a follow up/pics when I get it straight. I sure would appreciate any input from you good people.

My reasoning for doing this is:

1. If I just remove the air particles, I won't have a chance of breathing them.

2. Small micron bags reduce the effeciency of the dust collector blower. Regardless of what you hear online, a smaller micron bag will reduce effeciency. It has to, it has a smaller weave there fore creating a pressure head to the blower.

3. Space effeciency, my shop will be 10 1/2 ' X 22 '

4. No bag cleaning, just empty the barrel (outside of the shop)

I'm doing that now with my cyclone. VERY little dust escapes to the out side. The down side is that it sucks all the A/C or heat out of the shop.

What's A/C and heat in a shop? Shure would like to have that heat thing.

[Tom Miller]

Just remember, all those cfm's will be replaced by outside air coming back into the shop, whether you design for it or not. If you don't design for it, though, you may starve your DC system of cfm's.

Regarding make-up air: if you think the air coming out of your DC filter is cleaner than outside air, you could plumb that back into your shop. This has the added advantage of saving any heating, cooling, or dehumidifying of that shop air.

Regards,
Tom

Larry & TOM,

Good points you guys made. As far as heat goes, I probably only use it 7-10 days during the winter in the garage. My make up air will be through the front of the garage. I used to lift the garage door about 6 inches, and will be doing the same again. Luckily we have a ton of nice days here in the winter. Va. Beach winters are fairly mild.

[lrogers]

Va. Beach winters, I remember them well. I graduated from Princess Anne High School.

Dick, in South Alabama, A/C is just about a requirement, not only for the cool, but for getting rid of the humdity. Heat isn't nearly as important, but I do like my comfort!

You might also want to check your state and local laws regarding discharging sawdust to the outside air; apparently it's not legal to do this in some places.

[Jim-Iowa]

Do they still hang laundry out in your part of the country?

I would sure hate to come face to face with some woman whose clean laundry had been covered with fine sawdust?

[dlminehart]

Or discover your neighbor was painting the exterior of his house!

For some reason it's real impulsive to think of blowing your "refuse" out of your dwelling - this is the attitude that has made man the biggest polluter on the earth.

Besides the effect on the environment the next thing that should cross their minds is the fact that they are not only sucking dust out of their room but also about 500 to 1000 cu ft. of air, every minute.

That's about 1/4th the volume of a 2- car garage. so in four minutes all the air inside the garage will be outside the garage, assuming the DC is allowed to do its job.

If you have an AC or a heating unit, assume it takes 20 minutes to pull the air in the room from outside temp to inside temp. So you'd probably need 6 times the a/C or heating capacity you had before.

Oh yeah, you'll be pulling in 1000 cu ft of air per minute from outside (otherwise your garage would collapse from the vacuum). So you have to have a low restriction inlet into the garage from outside lest you reduce the efficiency of your air cleaner. A furnace filter filter of approx 12' x 8' covering an opening 100 sq. ft (50% bigger than a single-car overhead door) would suffice. That's about the size of a low restriction pleated filter. Something like 30 sq ft might work, but it would have the equivalent restriction of putting two layers of bags on your DC.

Why do you need a filter? Because otherwise you would suck in pollen, dust, and other airborne junk including yours and your neighbor woodworker's discarded sawdust (since that appears to be the custom in your neghborhood).

Ah, if you lived in houston, there would probably be several gallons of water sucked in too, masquarading as humidity. Probably good for your cast iron tools.
