TT66' Thanks guys, I'll do some checking into that equipment. Fittings.....restriction. I didn't think about the fittings. I need to look at the v type. That maybe the first thing I try. It certainly would be an inexpensive upgrade to see if that's the problem. All very helpful and I appreciate your suggestions.

SteveU Check out Eaton compressors site, they have 2 different regulators, 1/2" and 3/4" the 1/2" is $60 & the 3/4" is around $80. I have the 3/4" model on mine & get plenty of flow, changed everything over to type V fittings & noticed a big difference by doing that. Comparing these to the type M I had before is like comparing the barrel opening on a .357 to a .22. Get some of the type V fittings if you don't have them allready. They have the added advantage in that the type M fittings will also work with the type V quick connects but not vice versa. Your Quincy 5hp should be plenty, my Eaton is a 5hp single stage & is all I need as it will pump up & shut off while running a cheap (read airhog) 6" DA sander or 1/2" impact.
Good Luck,
Steve

oldred TT, First about that compressor, you choose well as Quincy is a VERY reputable outfit and they build some of the best compressors made and if you plan on wearing that thing out before getting a bigger unit you had better be prepared to wait a looooong time! You can believe the numbers that they claim and count on the amount of CFM that will be listed. I would suggest a Sharpe 880a regulator unit but if cost is a concern then some of the newer HF outfits work darn good too. It sounds like you do have a restriction and if so then a new regulator could solve the problem just make sure it is indeed at the regulator and not some place else in the line. I have even seen some of the Chinese pipe fittings with the inside choked down to a fraction of the supposed size so if you have anything like that it might be a good idea to check them out also.

TT66' I do have one of those Harbor Freight setups pictured above but its an 80's model and I don't have the cfm rating for it. It's too low though. I have a 5hp Quincy but it is a single stage . I know I should have bought bigger but at the time that was $1100 and a two stage was even more. I was having trouble coming up with the even more part. Times have changed in which now you can get a very good 2 stage for that price. My Quincy is no slouch it does keep up pretty good though. I'm pretty sure the restriction is in the regulator orifice which is too small and produces low cfms. The tools start out fine and when the volume of the 3/8" hose runs out the regulator won't keep up. I was just wondering if anyone had some advice on a good regulator that will flow well and reasonably priced. I appreciate all the input so far and nice pictures, very good ideas guys.

TT, you say you have a 5 HP 60 gallon compressor? but what is the CFM rating? Do you have a regulator now or are you running straight tank pressure? If you are running out of air, and it sounds like you are, then no regulator is going to make up for a lack of air from the compressor. Does the impact or cut-off tool start out ok for a while and then die down or does it lose power almost immediately? If it only runs a second or two before losing power then it could indeed be a regulator problem or (more likely) a line restriction. If the tool runs for a while and then slowly loses power along with a corresponding lose of pressure in the tank then the compressor is not producing enough CFM and the regulator is not the problem. Check the lines for a restriction and make sure there are no fittings ANYWHERE in the system that are smaller than the line.

Danny, nice set-up you did a really good job on that
True, an extra tank won't help if you are running out of air. But like you say it can reduce cycle time but as in life there are trade-off's with everything and every decision...the trade-off here is it runs longer to fill both tanks...

My experience running smaller compressors is the additonal tank will help cool the air and collect some more of the moisture and another benefit to having an additional tank is - if you plumb it right, its easy to disconnect and take with you for emergency tire repairs and such.

Danny G. Oh thanks so much Oldred You were a big factor in me wanting to take it this far. I knew you were a good source of info to follow, and really were into these things too.

I had a feeling you were going to mentioned that about the tank assist. Especially on a single stage 60 gallon like mine, wich is a 15 amp US General. When I'm using cut off tools, die grinders and HVLPs, its doing the job, but its constantly on working its tail off like I expected it to. I've been keeping all the regs set at 90 PSI and its been working great so far.

TT66 what compressor and regulator are you using?

matt167 I use 1 of the HF blue filter regulators for paint, only problem I'v had is the T handle on the drain valve came off so I use the appropriate sized wrench to open it up. works great. use the HF olive green FRL oiler/ regulator, and it works good also, use it for air tools. I also have 2 $40 craftsmen regulators that work good.
11-11-2006 05:53 PM
Danny G. I really like seeing how others got theres all setup too. Been using that blue HF filter for a while now and its been working well. Only problem was it leaked at the regulator going into the filter part, just had to reseal it with teflon tape. Can't really be upset for $20.

I used copper too. 3/4" When it wasn't $o much. I liked the setups at www.tptools.com and followed the Sharpe diagrams. I think it was actually designed/started by Kosmoski? Mines up 6", back down, then up 8" again to the regs.

Heres the HF filter after about 40 ft for the air to cool.



Sharpe F88 $44 with an HF filter reg. Same 25 ft retractable like Rambo's shown above This ones after around 65 ft of copper.


I got bored and used some 1/2" pipe after first 25 ft, and used a Craftsman regulater that was given to me. No filter, just an engine bay/misc drop.

An additional tank will help - although it will run longer to fill up the additional volume.

Harbor Frieght Air Filter Regulator

I have been using one of these with a smaller compressor and it does a pretty good job.

I plumbed a kind-of "stil" setup to with copper to cool the air and give it a collection point before even hitting the filter...

air regulator

I do not use one on any air tools except a spray gun. My line pressure is between 130-150 psi. I have noticed any abnormal ware on any of the air equipment.I have to say all of the air equipment is old, but name brand CP, IR, Snap-On which was BM (Before Marriage) ...russ
11-11-2006 10:14 AM
Y2K I'd suggest getting an extra tank for more capacity.
60gal goes fast with airtools like an impact gun.
