Help WantedHammer man for circular saws.Year round work at Nordic Saw & Toolin California 800.345.3535

This is on the front page because it is abig problem many places and is goingto get worse. Ask yourself, if you werea hammer person would you want yourson to go into the business. At one ofmy speeches lately I met an old friendwho just had his third mill closed underhim. This guy is good but he thinks hewill take early retirement and dosomething else.

One small solution is saw tips that staysharper longer. Our Cermet 2 tips last2, 3, 5, up to 10 times as long ascarbide. If you service saws for othersremember that you can probably chargeabout twice as much for a saw that runsfive times as long.

Why Terry Payne got a great dealWe had a large quantity of special tipswe bought surplus. (See p.2) We startedsending out fliers advertising half inchtips for $0.10 each. Terry Payne gotback right away and offered to takethem all at a lower price. We said surebecause Terry is absolutely honest. Hehas a well deserved reputation forkeeping his word. He pays in full andthe checks arrive on time or early.

On the other hand we just lost a famousname customer. We got so tired havingto fight to get paid that we doubled ourprices and asked for a third up front.

We know the laws and we treat ourcustomers equally however one of theclasses we use is whether they pay ontime or not. You may think you arebeing clever by paying late but there arealso advantages to being honest.

Long Life Pallet Saw BladesMike Goodpasture at FabricationSpecialties in Centerville, TN waslooking for longer life out of his sawblades.

He is now getting at least twice the lifehe was before he started using sawsfrom Murphy Saw Shop in Redmond,OR. He is using asymmetrical sawblades to control vibration. Long life isachieved by using Cermet 2 tips fromCarbide Processors, Inc, in Tacoma,WA. The specially cut saw plate issupplied by Peerless Saw Co. inGroveport Ohio (800 973-3753). Thesaw blades are built at Murphy Saw inRedmond, Oregon (541-548-2515) byMonte Murphy and Steve McCall.

Cermet 2 in MelamineThis is the best cutting blade he hasever used. The customer is cuttingpallets of Melamine, about 25-30 sheetsper pallet. The normal standard gradeblades he uses cuts about 1 pallet beforeit needs to be resharpened. With our 10x 80 Cermet II blade, he finished 3 pluspallets before the blade needed to beresharpened.

CP2002 Double Bag Wall Mount Unitwith first pass through 25 micron filterbag and second through a 5 micronfilter bag, both vessels drain at thebottom.

Customer tried to run the 10" dual glasselement but preferred to run the bags,due to the lack of flow he was gettingwith the element cartridge.

He's been running 2 filter bags forapprox 2-3 weeks at this point and ishappy with the way the unit is workingand is ordering more units.

Picture is of the regular 2002 wallmount. The new unit looks the same buthas two drain plugs.

Call Jackie to order.This is a big dealbecause it is the firsttime Jackie hashelped a customerdesign a custom unit.Jackie is a sweetheartand really, really wants to do everythingright. Designing this unit got her wellout of her comfort zone but, by golly,she did it.

ST 660 Infrared ThermometerA pretty good deal especially for the

price.

We bought this because we figured wecouldn’t go wrong for under $100. Welike it and asked Mike West of CascadeHardwoods to test it in a saw mill.

The ST660 Infrared Thermometer is a

Infrared, Non-contact thermometerdesigned with an extra widetemperature range-50 ~ 999 ºC (-58 ~ 1830º F )

Long time measuring reliabilityLaser sighting On / Off is switchableBacklit LCD displayF or C selectableElectronic trigger lockTemperature data storageAudible alarmsCase Included

Tom,Thanks for letting us play with thatinfrared thermometer. We have a moreexpensive unit here on the plant site thatI borrow from the maintenancedepartment when I need to but it wasnice to have one at my disposal.

One item that came up that I used it onwas one of our gang saw lube systemwater boost pumps. When they start togo out they get real warm. How warmI’m not sure but they get warm.

I have four of these systems in use and Inoticed that the daily pressure readingwas low for a few consecutive days. Itook the thermometer out to thatmachine to check the temperatureagainst the other similar pumps. It wasactually cooler than the other ones so Ilooked elsewhere. I discovered that thewater flow was higher than normal andthat my flow meter was off. Flow goesup, pressure goes down. I have neverused the thermometer to check thesepumps but I will now. The pumps aremounted up on the panel so the gun isan ideal way to check them..

(Aimed directly at reflective babbittsurface)

Another thing I used it for was todouble-check our IR thermostat on ourlarge babbitt pot and to check thebabbitt temperature on our small pot.

One thing we discovered when wedeveloped the thermostat was that theinfrared sensor does not workaccurately on a reflective surface. Wehad to aim the beam at the crucible justabove the babbitt level and not directlyat the babbitt.

(Aimed at wall just above Babbittsurface.) There is a bright red dotfrom the laser that doesn’t show up verywell here.

We also played with the thermometeron welds and on our stellite tip annealerto see if it had any practical use there. Ithink that with more time to play with itwe would come up with a holder ofsome kind, possibly magnetic, that wecould use without having to hold it still.Once we found the right temperaturewe could use it for testing andcalibrating our annealing times.

One of the most important uses myresearch assistant and I found waschecking to make sure our backyardexperiment had desirable results. Byoccasionally checking the temperatureof our experiment we were able toachieve the desired results consistently.

Thanks again,

Our testing facility is always at yourdisposal.

Super “C”Carbide Grade

Tougher than C1 - Better wear than C3

What Makes Super C Tips TrulySuperior1. Superior Abrasion Resistance -Abrasion or straight wear is counteredby smaller, better grain size.2 & 3. Superior Adhesion andDiffusion Resistance (corrosion andchemical attack) Super C grade ofcarbide has an extremely fine structureso there is very little binder presented tothe material being cut. This, combinedwith the special metallurgicalformulation the Super C binder (hint -it’s not just plain Cobalt) creates anextremely wear and corrosion materialfor use in wood, plastic or non-ferrousmetals.4.

Report from MarvinWindows

On the saw that we tried. How manytimes we resharpen a blade before weorder new or have retipped we are notsure. Most blades get damaged byhitting something so we have thecarbides retipped a lot. How often doregular blades have to be resharpened?We normally have our carbide tippedblades sharpened every week.

The new Cement II blade normally lasttwice as long before it gets damaged.The best so far is four weeks and oneand a half million cuts before wechanged it out which is four timeslonger.

Hope this helps and keep up the goodwork on those tips.Nathan Hull, Grinderman

Purified Flux30% To 100% Better

Braze Joints(50x magnification)

Purified fluxSmooth &consistent

Standard fluxLarge grains offoreign material

You can see and feel the differenceimmediately.

Purified flux is black flux that has hadextra processing steps. Theseprocessing steps take the black articleout and leave the flux a rich, creamybrown color. If you take a little of eachflux and rub it between your fingers youcan feel that Purified Flux is not onlysmoother but the particles are smallerand there are no extra large particles.

Flux is made to prevent oxygen fromgetting to the parts as they are heated.Steel and especially tungsten carbideoxidize at room temperature. Thehotter they get the more they oxidize.Above 1,000 F tungsten carbideoxidizes extremely rapidly and forms anunbrazeable surface. Purified flux isgood for more time at highertemperatures, up to 1,700 F.

The original idea with flux was that itwas to be applied on top of the brazearea. However the critical part of sawand tool brazing is what goes on insidethe braze joint. Ordinary flux isinexpensively made and has up to 10%odd size particles and non-activeminerals in it. These odd size particlesand non-active minerals get lodged inthe braze area and can seriously effectthe strength of the braze joint.

Purified flux is cleaner, smoother,creamier and much more effective.

Braze Alloys (SilverSolders)

The right braze alloy can make ahuge difference in performance

Stop tip Loss - Prevent CarbideBreakage

Saw tips are brazed onto a steel sawusing braze alloy. When a tungstencarbide saw tip breaks it is usually badcarbide, the wrong grade of carbide, thewrong braze alloy or a combination ofthese.

The brazing process forms a three partcomposite. The success of thecomposite depends on the tungstencarbide, the steel, the braze alloy andthe way it is all put together. Thebraze alloy has to do three things. l. Ithas to keep the tip on the saw. 2. It hasto cushion the tip because the tip suffersa lot of impact stress when thesaw cuts. 3. It has to compensate for thedifference in expansion between steeland tungsten carbide as they areheated and cooled during brazing.

Filtering Straight OilCoolants

We now have a filter system that filtersstraight oil coolants. Above is our CP2020 which filters tight oil coolant verywell. It is also available as a wallmount unit.

Here is our CP 2002, which has been anextremely good unit on water basedcoolants for about eight years.

We have tried it on straight oil withvery poor results. It filtered for maybean hour before it plugged up.

Oil is much thicker than water. Thefilters were good enough to filter the oilfor awhile but, as soon as they started toa load up with dirt, the oil was too thickto get though.

Here are the two units side by side.

A filter is a series of holes thatseparates particles from liquid.Oil is thicker than water so it is harderto filter out small particles.In addition oil transfers the pressurefrom the pump directly to the filter andis much more likely to collapse a filterelement.

The secret is a high-tech filter. This isstainless steel inside and outside tohandle the pressure. It is smaller thanour water filters and has a pleatedsurface to provide sensational filtersurface area at the high pressures oilcreates.

We recommend monthly filter changesbut many go much longer than that.

Coolant filter LifeWe recommend a filter change after onemonth in use on a single machine whichis about 160 hours of use. In our testswe have seen them go 21 days of 20hour shifts, which is 420 hours. Manyfolks get 2 or 3 months out of the filterswhich is 320 to 480machine hours.

The rating is based on the amount ofsludge generated by the machine in anhour. If you run a machine 40 hoursand filter one hour then you remove allthe sludge from the 40 hours ofrunning.

If you are running 11 machines thenyou are getting 440 hours life out of thefilters in a week.

Two things can happen. 1. If filters arerun too long they can load up andreleases over and over so they don’t doany good past a certain point. It lookslike they are working, however. This islike pouring fifty gallons of water in afive gallon bucket. It works becausewhen you are though the 50 gallondrum is empty and the bucket is full.You just ignore the water on theground. 2. After a long enough timethere will be a lot of sub-micronparticles in the coolant and this can giveit a gray color.
