Saw Steel and TemperatureThis article came about because of aquestion from a customer. Thecustomer wanted to know how hot youcould safely get saw steel.

Saw steel can be hardened or softened(annealed) by heating it then cooling it.How hard it gets depends on thechemical composition of the steel aswell as how the heating and coolingcycles are run.

(Saw Steel & Temperature cont.)Brazed carbide tips need to be about1350°F for about half a second or alittle less. The metal alloy tips need tobe about 2400°. This is obviouslyabove the heat affected temperature ofthe steel saw body.

There are two methods to preventdamage to the saw plate. The firstmethod is to control the time andtemperature. They heat is presentedthrough the carbide into the braze alloyand then the steel. If this is doneproperly then you have a very thin layerof hard, brittle metal right behind thecarbide tip. If too much heat is used inthe heat affected zone of brittle metalmoves further down the steel sawshoulder. Imagine a line drawn acrossthe shoulder from the bottom of onedollar to the bottom of the next. Thecloser the heat affected zone gets to thisline the more likely you are to have aproblem with snapped shoulders.

The second method of controlling theproblem is to go ahead and heat the tipanyway you wish and then temper thesteel after brazing or welding.

Heat can be a real problem whenrunning the saw as anyone who has everhad a stick caught in a guide can tellyou. Affecting saw steel bytemperature is actually affecting sawsteel by a combination of time andtemperature. You can subject saw steelto a 4000°F oxy-acetylene torchwithout damaging it at all. Obviouslythe secret is to just briefly wash theplate in the flame from the torch. This issort of the same idea firewalkers usewhen walking on hot coals. You need tokeep moving and you don't get burnt.You can also see the same thing whenyou drop an ice cube into boiling water.In spite of the temperature difference itdoes not melt completely, immediately.

Conclusion:You can get saw steel as hot as 1400 to1450°F during the tipping operation ifyou control the time and the heat sourceso that you only affect an extremelythin layer behind the tip. With brazingcarbide or metal alloys and withmelting braze alloys by welding you

will affect the steel and really shouldtemper it after you are throughattaching the tips.

If you get your saw plate to 1300°Fduring operation you should probablyscrap that saw blade. If you wanted to,and you had the skill, you could torchtemper just that area of the saw platethat got too hot. This doesn't work verywell but you might be able to get by.This is also extremely dangerousbecause you risk the possibility ofhaving an embrittled saw plate that isgoing to come apart on you during use.

How to Measure BrazingTemperature At The Back Of the

JointMany wear applications use tungstencarbide brazed to a steel body. In manycases the piece of tungsten carbide canbe very large as well as very thick.Even brazing a relatively small part,such as 1" x 1" x 1", presents theproblem of how to determine when theproper temperature has been reached atthe deepest part of the braze joint.

This drawing is made to represent alarge piece of carbide being brazed intoa large steel holder.

A common method of doing this is touse a tri-metal ribbon also calledPlymetal©, sandwich material orsimilar. This material is braze alloy oneither side of a copper strip. At theflow temperature of the braze alloy thecopper anneals into a dead softcondition. This “dead soft” layer ofcopper helps relieve the considerablestress caused by the difference inexpansion rates of the two materials.

I show the sandwich braze material asthe darker gray material between thecarbide and the steel base.

The problem is how to find out whenthe braze alloy has reached its fullmelting point. The area represented bythe question mark is meant to representthat part of the braze joint that isfarthest from heat source whether it betorch, induction or something else.

A solution that I have found very handyover the years is to use a very small bitof wire at the very back of the joint.This raises the carbide up just a bit.When the heat penetrates all the wayback the braze alloy wire bit melts andthe carbide part settles down.

Two points:1. This drawing is wildly out of scale.If the carbide part were 1" x 1" x 1"than the piece of braze alloy would besomething like .046 inches in diameter.2. I don't believe that this iscompletely accurate but it is certainlybetter than no indicator at all.

Two Ohio HuntersTwo Ohio hunters, Paul and Steve, gota pilot to fly them to the Canadianwilderness where they managed to bagtwo Bull Moose.

As they were loading the plane toreturn, the pilot said the plane couldtake only two hunters, their gear andone moose.

The hunters objected saying, "Last year,we shot two, and the pilot let us takethem both . . . and, he had exactly thesame airplane as yours.

Not wanting to be outdone by anotherbush pilot, he gave in, and everythingwas loaded. Unfortunately, even underfull power, the plane couldn't handle theload and went down in the wilderness.

Somehow, surrounded by sleepingbags, clothing and two moose, Paul andSteve survived. After climbing out ofthe wreckage, Paul asked Steve, "Anyidea where we are?"

Steve replied, "I think we're pretty closeto where we crashed last year."

ISKA SpeakersIntooligenceJim Baad, Vice President ofIntooligence, brings 5 years experiencein Information Technology and spent 2years in the woodworking toolingindustry and serves as a bridge betweenthe needs of the woodworking industryand the capabilities of informationtechnology for Intooligence. Thismeans that the speaker knows how toolsare made, knows how tools are usedand has an excellent understanding ofmanufacturing processes.

(Following is information as suppliedby the speakers)

Intooligence - Jim BaadIntooligence Pro and Enterprise areour offerings for end-users of tooling.They include features like tracking andsearching tool inventory, tracking theusage of a tool and cost-per-foot of atool, managing machine preventativemaintenance and maintenance tickets,and text and email alerts for when amachine needs maintenance or a toolhas been damaged and many more. Wehave had good success with this in 2011and we are excited about 2012 and theopportunities that are developing forthis coming year. Many of you mayhave customers that are demandingmore accountability with their tooling,ex. tracking their tooling, numberingpanel saw blades, cross-checkingpaperwork, etc. We have found thatthese types of customers are looking fora solution like Intooligence andappreciate when their tool-sharpenertells them about a solution to help themorganize their tooling. Many tool-roommanagers are being asked to be moreaccountable with budgeting, tool-life,and other price factors and they needsoftware to help them generate thisinformation. Some of you may bewondering if this would make your lifemiserable to have your customerstracking tooling that you service. Wehave found the opposite to be true;Customers will have the ability to giveyou better data about a tool,replacement part numbers, CAD files,and projections of how many piecesthey actually need.

Intooligence TS is our solution fortool sharpeners. It consists of a tabletthat you can take with you into thecustomer and electronically record thedrop-off and pick-up of customerstooling. We also have a wireless printerthat you can hook on your belt and printout receipts and if you have tech-savvycustomers they can receive automaticemails at the end of the day with whatyou delivered and picked-up. You canconfigure your routes for each day andsales-person and see what you have in-house for each customer. In the officethere is software to automate the importof invoices from Intooligence into youraccounting software, ex. Quickbooks,etc which reduces the time it takes toenter invoices. Intooligence TS wasbuilt knowing that every sharpener hasdifferent prices and categories oftooling that they service and becausethat everyone can have their servicecodes and prices in their tablet(s).We've found through extensive testinglast fall and this spring that there are alot of other benefits to having tabletswith your sales-people on the road,including email, pictures, videos, PDFfiles, etc that really help your sales-people be more effective at answeringquestions and communicating ordersback to the office. The comments fromthe customers has been the mostinteresting with many of themimpressed at the level and technologythat the sales-person now has in theirhands. The tablets are an excellentavenue to show videos and photos toyour customers on how you servicetheir tooling every week.

Rief Mediahttp://www.riefmedia.com/Chase Rief of Rief Media is the son ofISKA’s own Tim Rief. He grew upworking in a top quality saw shop, wentto college and got his degree.

Chase Rief of Rief MediaThree questions to ask yourself aboutmarketingA lot of businesses like to put up awebsite and think that clients will comeautomatically from that. They don'tthink about all the steps involved ingetting the marketing setup correctly,and then once it's setup, the stepsrequired to make sure people can findyou and will do what you want.

Below are three things to think aboutwhen setting up any marketing oradvertising - online of offline.

1. Have a goalWhat is the goal of your marketing?Everything you do should be measuredas much as you can so you can allocatedollars correctly and will know what'sworking.

2. What's your plan?Now that you have a goal and knowyou want to market yourself andadvertise. What's your plan? There aremany ways to measure from couponsused, visitors to your site, to customtracking phone numbers. Each of theseitems would move things arounddifferently to promote the goal in adifferent way.

3. Have an online presence that is easyto use and resonates with your clients.You need to have a website thatlegitimizes your business. It should beclean, easy to navigate, and show offwhat exactly you do quickly andeffectively. Once you've shown thevisitors what you can do - let them getahold of you! Make sure your phonenumber/address can be found easily.

There is never a better time to start thannow! Start small and be sure tomeasure and test your marketing. Onceyou get going you can always expandyour reach!

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 laststwice 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, GrindermanMarvin Wood Products

Brazing ProceduresSpecifications

Example: Brazing Tungsten Carbide toSteel

Note: this is a general overview. It is,in no way, meant to be suitable forany specific application. It is to serveas a guide and a base for brazingapplications in general

1. SafetyA. List of dangers - flux fumes,perhaps cadmium in the braze alloy,Zinc fumesB. Methods of exposure - inhalation,smoking or eating without washinghandsC. Avoiding exposure - work under thehood. Use smoke sticks to verify hoodeffectiveness. . Wash your hands.D. Other safety considerations. Do notget burned. Even parts that have cooledconsiderably can still be hot enough toburn you.

2. Surface conditionA. Is plating necessaryB. RoughnessC. Free carbonD. OxidesE. Oils and greasesF. Surface cleaning methods

3. Test methodology for surfaceconditionsA. Eyedropper method of water breaktest - use an ordinary eyedropper andgently put four drops of water onto thesurface to be tested. If the water formsa high bubble the surface needs to betested. If the water forms a flat puddlethe surface should braze well.

4. Ambient conditionsA. Cold shop - A cold shop, commonon Monday mornings, can affect heattransference and cycle times.B. Cold fixturing - Cold fixturing cansuck the heat out of the braze joint.Typically the fixturing is on the underside or the back side. Quite often thereis a good joint on the visible side and acold joint on the fixturing sign.

5. Alloy selection - alloy selection maybe the most under-appreciated part ofbrazing.A. Suitable for materials being joinedB. Desire temperature rangeC. Desired strengthD. Desired costE. Safety e.g. Cadmium

6. Flux selectionA. Suitable for braze alloy temperaturerangeB. Robustness - some fluxes hold uplonger than others.C. External fluxing - fluxing outsidethe braze joint onlyD. Internal fluxing - fluxing incised thebraze joint. A more purified flux maybe needed

7. Braze joint thicknessA. Tensile strength versus impactstrength - a thinner joint typically hashigher tensile strength while a thickerjoint gives more strength against impactparticularly where there is a greatdifference in thermal expansionbetween the two materials being joined.B Amount of alloyF Fixturing pressure - too muchpressure can squeeze the liquid alloyout of the joint

8. Internal temperaturemeasurementA. “Rock in shoe” method - whenbrazing large parts it can be difficult totell when the proper temperature is beenachieved in the thermal center. Onemethod to determine this is to put a bitof braze alloy wire in the center of thejoint. When the wire bit in the Centermelts the parts will shift and you knowthe temperature.

9. HeatingA. Heating method - torch, induction,oven, atmosphere, frictionB. Maximum temperature - how hotcan you get the braze alloy?C. Heat of transformation - (50º Fabove flow point) (Much more thanheat of transformation is involved here.)D. Cycle timeE. Maintenance of equipment e.g.Fluoride based flux fumes etchingoptical sensors

10. Movement of partsA. Keeping parts where you want themB. Moving parts at temperature -sometimes desirable to release trappedflux fumesC. Amount of movementD. Movement pressure

11. Post braze analysisA. Gaps and voidsB. Uniform flowC. Braze joint thicknessD. Difficulty of cleanup - brazingfluxes are typically easy to clean upwith warm water and a little scrubbing.If this is not the case, quite often it isindicative of the fact that not enoughflux was used.

12. CleanupA. Method - typically warm water andgeneral agitationB. MaterialsC. Tools – e.g. brush, tumbler, strainerD. Safety – wear eye protection ifbrushing, wash hands afterwards

Science Dog says “Happy to help”

A Chinese WoodworkerA Chinese woodworker recently openedhis shop to discover that sometimeduring the night a significant quantityof his rare wood blanks had been stolen.Looking for clues, he discovered achild's footprints in the floor's sawdust.The woodcarver decided to lie in waitto capture the thief. Sure enough, thatnight he heard a noise. The Chinesewoodwork jumped from his hidingplace and flicked on the light.

Standing before him was a SEVEN-FOOT tall BEAR with itty-bitty feet!!!

Thinking quickly, the craftsmanhollered: "Ah ha, I've caught you, boy-foot bear with Teaks of Chan!!"

Average Braze Alloy DepthWe prefer to specify alloy depth by aterm called “Average Alloy Depth.”This treats the part as though the alloywould form a flat topped, straight sidedlayer. This makes it very easy tocalculate from either volume of weight.

About the best way to treat the surfaceon the basis of crown height is to treat itmathematically as a truncated pyramid(a frustrum.) This has two problems.1. The accuracy is, at best, only within5% 2. The contact angle between thebraze alloy and the underlying materialis a rather important means ofmeasuring wettability and hence thesuccess of the flow and the bond.

Overheard at a Filer’s MeetingHe said “Look at those two old drunkssitting across the bar from us. That's usin 10 years".

She said "That's a mirror, dip-shit!

Thanks to Tim at Bill’s Sharpening inIllinois

FreeA steel cased inspection mirror.New- now with free magnets

These are used by many to inspect theback side of saw blades and other toolswhile sharpening is in progress. Theyhave a steel case which makes itpossible to mount the mirror with amagnet on band saw grinders and othermachines. You can also slip them in apocket and use them as a hand heldinspection tool.

Free Internet advertisingThe Internet is full of directories thatare similar to the Yellow Pages.

If you are a saw sharpener in DesMoines Iowa do a search for “sawsharpening Des Moines”. You will seea long list of directories. If you are asaw sharpener in Des Moines you reallyshould be on this list and you can get onit free.

If you click on one of the results in thesearch page it will give you a list of sawsharpeners in Des Moines. Somewhereon the page (maybe in the top right)there will be an option to add yourbusiness to the list.

These directories want every businessin the country listed. They are doing thesame thing that the Yellow Pages do.They will give you a small, basic, freelisting.

As you go through the process ofadding your information you will alsobe given the options of buying lots ofstuff. You can buy bigger ads, specialplacement, maybe special fonts oralmost anything. But there are dozens,if not hundreds, of directories whereyou can list your business for free.Remember to list yourself withsurrounding towns as well.
