Re: Quincy compressors
This 2 hp Quincy compressor seems very much like the unit I have. ?Mine is a 2 hp unit with a 26 gallon vertical tank. ?I bought it direct from the local Qunicy rep because he quoted the best price. ?I was looking for a unit not manufactured in Asia and there are not many in this category. ?The rep told me it was all American made. ?I believe that was true with the exception of the "2 hp" motor which was made in Mexico. ?I've had mine of almost two years so I can't say where they are currently made.
Yesterday I took some some measurements with an app on my iPhone. ?While I can't vouch for the accuracy of these reading here they are: Background noise: ?46 db Running Compressor: ?77 db So far the unit has worked well and I have no complaints. Hope this helps. Scott Long Beach, Ca. |

Re: Dust Extraction
开云体育I would think 2 100 would meet your requirements ?. Two 125 is quite a bit larger than your a 160 opening. 1 ft of flex equals 10 ft of pipe in resistance.? martin/campshure/co/llc 608-824-0023?fax Designing and building for 47 years On Feb 3, 2017, at 5:46 AM, John Kee jmkserv@...

Re: Dust Extraction
Hi Jonathan. Based purely on airflow and dust collection considerations and no experience of drum sanders, my thought would be to do all you reasonably can to maximise the airflow/CFM into and through the sander.
Sanders produce fine and easily transportable dust which (a) means you can probably gain some CFM by increasing your vertical duct size at the cost of reducing your vertical airspeed from the normally recommended 3.5 - 4K fpm without running into problems, while (b) the increased inwards airspeed enabled by the extra CFM in the volume surrounding the hood should (depending on how well designed the hood is) help reduce the amount of dust that escapes. 2x 100mm dia hoses combined have about 40% less open area than your 160mm header. 2x 125mm dia is about 40% larger, which would drop your nominal header fpm airspeed by the same %.? Flexibles tend to be more restrictive than smooth ducting - another reason not to skimp on size. If you are running header CFM typical of a well endowed and free flowing/unrestricted 160mm system (genuinely delivering Pentz/CV 1800/RL160 style or better airflows) the 125mm flexibles should be OK - although staying with the 100mm ports will further (and significantly) reduce the fpm/airspeed through them and offset much of the CFM benefit of their 125mm dia. This on top of the above 40% fpm/airspeed reduction as a result of their combined open area being larger than that of your header. i.e. there may be a decent CFM and airspeed gain to to be had by installing 2x 125mm ports on the sander. This will only deliver if the hood isn't restricted elsewhere. i.e. try to estimate the minimum open area in the hood, and ensure that it's larger than your 2x 125mm ports before doing anything. I have a roughly 8ft length of 125mm flexible lifting vertically to a 160mm Pentz powered header drawing through a pretty restrictive roughly 600mm length of 100mm flex attached to the dust chute inside my K3 Perform saw cabinet - which still lifts everything except the larger offcuts that slip down into the chute just fine. i.e. i'd prefer to eliminate the 100mm hose and enlarge the connection to the chute for better flow, but it's not easily done because space is very tight. A sander is different, in that while it's not going to have to lift offcuts it probably would benefit from anything that can be done to improve your CFM/flow rate as above.... ian |

Re: Dust Extraction
If you have 125mm drops already without seeing the actual configuration I would run 2 of them and reduce at the machine. An alternative would be to run a new ?flexible 160 drop that divides with a Y into 2 100mm at the machine. On Fri, Feb 3, 2017 at 3:28 AM, jonathansamways@...

Dust Extraction
I'm about to hook up a drum sander in my shop.
The two top ports on the drum sander are 100mm The sander needs to be mobile so tubing needs to be flexible (two pieces of flex both approx 2meters long) My main duct is 160mm with drops at 125mm. My question is do I go flexy 125 mm or 100mm to the machine. Or any other suggestions? Thanks in advance. Jonathan |

Mine is a very old unit. Im not sure the exact year but it has the cast iron cover.?

I had been?thinking maybe i seated the bearings?wrong. But yes they are the right ones. I was walked through the purchase over at OWWM or whatever the sight is called. From what i was told this machine was one of the "good"old?ones. Anyway this is a compressor conversation my bad. Lots of old comoressors to be had on craigslist in the northeast. I would have to know what i was looking for though. On Thursday, February 2, 2017, murkyd@... [felder-woodworking] <felder-woodworking@...> wrote:

Re: Quincy compressors
开云体育Are you sure you replaced with correct bearings and loaded them appropriately? ? I'm not familiar with the Delta but old DP often run angular contact bearings.? The bit runs out until pressure is applied and then the bearing tightens up.? The proper way
is to use two bearings opposed to each other and loaded.? Then there should be no runout .? The quill or taper itself could also be the problem which tougher to fix.? Dave From: felder-woodworking@... on behalf of patrick walsh pwalsh651@... [felder-woodworking]

After Macs response i am thinking again.
Ill tell you this. I purchased a old Delta DP 17 over a new machine. I didnt know what i didnt know and just took it home thinking a overhaul wiuld fix any issue with runout. I replaced all the bearing and gave the thing a real good once over. Took it
apart piece by piece and did everything but paint it gefire putting it back together. The runout is terrible.?
Point is i still need a drill press after a solid 1.5 days work and $300 fort he machine and something around $100 for bearings. I really wish fir my purpose i had just purchased a new Delta or Powermatic. Or that new Nova mavhine. Probably also crap long
term but at least for now it will drill a straight hole. More than i can say for my Delta DP17.
Im sure old machines are much better over the long term. On the other hand you have to have the skill and desire to bring them back to life. Both of wich i found i dont have. Id rather be? making something or even better money.
So what would people purchase?if buying new??

Re: Quincy compressors
Not everything old is good. ?There are old machines that were mediocre or worse when they were new, and Delta made a lot in that category. ? In the middle of the last century they made a lot of stuff for hobbyists, high school shops, gas station/auto repair types, etc. ?That said, I have a DP-17 and runout is not a problem. ?Maybe your spindle is bent. ?It's not a very heavy duty machine and has a pretty lightweight spindle.?
Most old air compressors are quality however. |

Re: Quincy compressors
开云体育I also recommend the California Air Tools compressor, though mine (10020C) didn’t have the built-in dryer. ??Remarkably quiet for a 5.5CFM, 2HP compressor.? ?Only plaint:? the two suction cup-like rubber feet had to be replaced.?? However, Daniel at Cal. Air Tools was kind enough to replace them under warranty with a newer, more durable version.?? Support there is extremely responsive. ? Whether or not you need a dryer depends on the humidity in your area and of course, what you are using the air for.?? If, like me, you are not using the air for applying finishes, and you live in an area not subject to high humidity, you may opt simply to run at least 40’ of copper pipe (which cools and condenses out water vapor)? between the compressor and your nearest station, with the copper sloped toward drip legs.?? Would recommend also that you install an automatic (timer-operated) drain valve, which Cal Air Tools also sells (or could be obtained from Amazon or eBay). ??These can be had for about $100. ? |

Re: Quincy compressors
Belt drive is a lot quieter than direct drive. But, RPM is a key factor and didn't find the RPM spec on the compressor direct website. That compressor looks like an Asian built Quincy branded unit. The head looks like it could take 2HP to 5PH. With the lower HP motor they would run the pump slower and with a bigger motor they would run it faster. If true then it's probably pretty quiet.
I'd say get the RPM spec. and compare to other competitive models I have an old Quincy model 325 pump that can run either 3HP at or 5HP at twice the speed. I put a 3HP motor on and run it slow to be quiet. I think mine is 450 RPM now or it would be 900 RPM with the 5HP motor which would make twice the CFM but with more noise.
