Skou, it is all in jest!!!!!!!!!! I am as sober as Judge Roy Bean!!!
Shoot I only have 2 Ers now and they are in the basement. You have 4 above grade, "The floor is falling"
Phenix, on a slab!!!!!

Fiction loss depending on duct diameter and material, seems, elbows!!! Did the jerk put the connections in the right flow pattern???
So guys, and I know some of you where engineers, lets talk "turkey" here!!! Is it tube piping or cheap plastic with spiral wire???? Best vacuum flow needs an equal inlet flow at least to its suction flow for maximum flow!!! So you can have a 1,000,000 CFM suck and if the "machines" opening to atmosphere air is 2 CFM that is about all you are going to get!!!!!!!!!!! But great velocity!!!
You want to talk air flow, duct, piping loss, you better get out your Combustion Engineer Pocket book!!!!! I am sure JPG has it in his head!!!:D
Just take a 3K CFM leaf blower, and try and blow it against a 2 MPH breeze, and see who wins out!!! It volume, not velocity!!!!!!!!!
I was 20 years old, walking through Sears with my future whore, vacuum sales man stops us, tries to sell me a vacuum cleaner, shows my it suck value, picks up a 16lb bowling ball with it, NO FREAKEN air flow on the other side of it, I knocked it off the suction tube, now it had an air flow past it, I said now pick it up!!!!!!!!!!!! Then I told him, she can do it too with her mouth!!!!! Jews like doing that!!! They "Stand by there man"
Thats why I always say, "do not f*&k with the Israelis"!!! Jordan just has and they are feeling the Rath!!

Please stop getting yer parameters confused!!!:eek:

BTW 'de' in front of anything like natured means it has been removed, so it ain't natural(nor fit fer human consumption). Oh and it is 'wood' alcohol aka methyl/methanol that causes blindness. Any 'blindness' caused by ethyl/ethanol is temporary as is other effects both good and bad.

Speaking of vac salesmen, I had one who liked to pick up a large ball bearing with his wares. He placed the bearing on the couch(home demo time) and asked me if I thought the vac would pick it up. I replied that that depended upon how 'porous' the fabric was. As it turned out, there was too much air flow through the fabric for it to pick up. Not enough static pressure 'difference' to overcome gravity.

Well I can see I am going to have to do some research into this if I want to do it "right". Today isn't the day though, I have stuff to do. Actually a camper to fix the roof on. A match might be a good choice to use as the main tool on this job......

I may just get "something" for today. Better than nothing right? And build a shop system down the road. Money is tight with doing a remodel on 1000 square feet of shop including heat, along with a paint booth installation.

But with what has been posted here, the shopsmith dust collector seems a bit shy on the cfm since it is rated at 330? (please correct me if I am reading this incorrect) While the HF is rated at 1550. Now before ya jump at me, that is ratings, I have not personally tested them! Also it has been stated that the HF unit is not really a 2hp (which I believe), but the amp rating (again if true) does justify a 1 1/2 hp rating. Everyone that I have found that advertises a 1 1/2 is actually pretty close to a 1/2-3/4 hp....... at 10 amps. So HF is actually "less inflated" than the name brands?

I get the impeller size, and that is going to take power to turn. I get velocity also. I work with setting up paint booths occasionally, (jack of all trades, master of none comes to mind!) and we deal both with cfm, air flow velocity etc.

Looks like I missed the delta. He sold it, it was an "OK" deal. That is why I asked questions before jumping. Since it was a lower end delta it wasn't that impressive of a collector anyway with a 30 micron filter. Glad I did some thinking before jumping on that one. Not sure I want a SS smith due to the low cfm. So this thread has been informative and eye opening.

Really from a "cheapness" point of view, I am thinking the HF unit can get me going today, and tomorrow the filtration system might be able to be upgraded? "IF" it truly pulls 1550 of cfm that is actually pretty impressive. Not saying I am going there, just throwing it out for discussion.

I see a brand that I hadn't seen before. "Pennstate" appears to have some decent stuff along with cyclone setups. Long term, a cyclone system may be what I want/need? Just isn't happening today due to the ca ching needed to purchase. But, sometimes I am able to find stuff reasonable when the ear is to the ground looking. I just picked up a $1,800 dollar air conditioner for my shop to replace the unit that seized up 2 years ago for $125.00. Looks like new also. Took me 2 years to find the right deal, but I am a scavenger!

In reality, I am not producing as much dust as many of you since I don't do that much "wood" work. But I can see where having a central system could help me in many instances on activities that I am involved in. Making a hood for polishing to grab some of the crap produced in that activity, cutting polycarbonate with a router to pick up some of the shavings as that is MESSY, having a vacuum source for hand operated sanders, and of course the shopsmith for my cutting of wood for patterns. That is why I would like a "shop" vacuum versus a mobile system for the long term.

Thanks for the help, and feel free to ad more info.

Oh, and rbursek, I think I need some of your "denatured alcohol" just to follow your posts! LOL I do like olives though, stuffed with jalapeno's.

Greetings ddub...

I'm still pretty green with this stuff but in my search for a dust collector I've gotten the impression that 2hp and up with 4 to 6 inch tubes is the way to go.
So, I've been keen looking at used Coral dust collectors ranging between 4 and 7hp.

Might be overkill, but I want to avoid as many headaches as I can so far as dust collection goes.

Seen this? http://www.shopsmithacademy.com/SS_Archives/SS109/SS109_Dust_Collection.htm

For starters, I suggest a dust deputy and shop vac with long 2.5" hoses.

The dust deputy will also work with the DC3300.

As time progresses you can then spend more ca ching on a setup.

The cfm is not an end all goal.

The most important thing is IMHO the filter.

Attaching to the dust deputy with a short hose, minimizes the distance larger particles travel and frees up the hose between the dc or vac for air and fine particles only.

As Nick points out, velocity is important to keep particles suspended in the air flow(prevents hose clogging). To maintain a given velocity in a larger hose/pipe requires greater cfm. So bigger 'sucker' with bigger pipes tend to cancel each other somewhat. However bigger does allow a greater amount of debris removing capacity.

Being a fairly recent owner of a DC, I am accustomed to the previous mess and may not be as picky about performance.

I do know that the DC 3300 with 20' of hose between it and the dust deputy and 6' or so between the dust deputy and the jointer will capture all that will go into the chute with an aggressive(almost 1/8") cut and very rapid feed rate.

The only downside to the dust deputy is that the container could be larger. Mine is a salvaged shop vac with motor replaced with the dust deputy(I purchased the cyclone portion only). It fills up fast when doing the above. I assume the 5 gal bucket would require frequent emptying. I also use that dust deputy setup with a small shop vac for portable use.

However the dc 3300 just sits there with an almost empty lower bag and is seldom 'emptied'.

DDub, just FYI, I picked up a like new Jet 1100DC for 175$ to day, then on CL was a Jet, NITB 500, for 100$, that I picked up for my nephew. Not to mention that ER 10!!!!!!!!! Busy morning of men buying!!! Woman shop, men BUY!!!!!!!!!

Both spend $.

FYI WOOD magazine has a coupon for 169 dollars on the HF collector.

Ya saw that and I think it comes with a 5 micron bag, I did not want to go that route, Too high of an amp motor from what i interpreted.
Both spend $.
No, woman spend there hard working man's money!!!!!!!!!!

Keep in mind the largest Shopsmith DC filter is advertised as 1 micron filter.
Mine works wonderfully - a whole lot better than either of the smaller hoods. More area = less air resistance.

Btw this is hard typing on my IPad. In Mesa in MH
