Dynabrade explores flexibleshrouded tools to see potential invarious markets.

Model 50570, A shroudedtool built to conform ➤

Model 50570 is a tool nearing release,expected to be available by September.This tool is a 3" (76 mm) 15,000 RPMright-angle disc sander (Model 52531)with the addition of a flexible shroud andvacuum/exhaust adapter. Thevacuum/exhaust adapter allows thevacuum hose to attach at the back end ofthe tool. Tool design keeps the vacuumhose inline with the air supply line.

The flexible shroud can be pressedagainst the work surface to achieveefficient contact. The use of a soft shroudwill greatly increase surface contact whenworking on uneven, contoured and convexsurfaces.

Front view shows were the vacuum hose attaches tothe shroud and the vacuum/exhaust adapter.Allowing for a comfortable grip of the tool, and notoff to the side where it could hinder maneuverability.

Shroud shown un-trimmed and ready foruse with products such as 3M TM Roloc ®

Exploring new areas for Dynabradeproducts, explaining what we needto know. Presented by ourcontributing author Steve Briggs.

Hexavalent Chromium ➤

What is it?

Hexavalent Chromium is a metalparticle used as a pigment in paints,inks, and plastics. It also is used as ananti-corrosion agent in protectivecoatings and in chrome plating.

It is known as a health hazard thatcauses lung cancer. In addition tocancer it can have negative affects on:

Respiratory Tract: Irritant to thenose, throat, and lungs. Repeated orprolonged exposure can damage themucus membranes of the nasalpassages and cause ulcers to form.

Skin: Prolonged contact can causeulcers to form and in some cases aserious rash can form.

Eyes: Direct eye contact with chromicacid or chromate dusts can causepermanent eye damage.

It can enter or affect the body in thefollowing forms: dust, mist, or fumes.

Commonly used names:Hex Chrome, Hex Chrom, Chromium 6,HexaChrome, and Cr(VI).

Where is it?

Primary industries affectedaccording to Occupational Safety andHealth Administration (OSHA):

• Stainless Steel Fabrication• Heavy Duty Coatings and Paints for:

- Automobiles- Train Cars- Airplanes- Boats- Ships- Electroplating

• Producers of chrome-based pigments• Welding (especially on stainless)•Spraying of heavy-duty coatings and

paints and chrome plating.

Hexavalent Chromium is farreaching. Mike Kirk is currently workingwith the Tennessee Valley Authority (anenergy provider) to assist them withbecoming Hexavalent Chromiumcompliant.

“The primary applicationthat we have been runninginto has been coatingremoval through repairand maintenance.”

What does it take to becompliant?

U.S. employers must provide aworkplace that does not exceed OSHA’sPermissible Exposure Limit (PEL) of 5micrograms of chromium per cubicmeter of air (5µg/m3). This iscalculated as an 8-hour time weightedaverage (TWA).

Employers are required to test everysix months if the Action Level of 2.5micrograms per cubic meter of air(2.5µg/m3) is met or exceeded. If thePEL limit is not met or exceeded, testingis required every three months.

An employer is not allowed to rotateemployees to different jobs to complywith OSHA’s guidelines. ➮

Above example is a refined powderform of hexavalent chromium. Thisform will be processed into inks,

paints, coatings, etc.

Example of hexavalent chromiumused as a paint/coating for a

helicopter fuselage component.



How can Dynabrade help?

We do not have a definitive solutionor a “cure all” that we can recommend.What we can do is assist an account toachieve compliance through the use of aquality vacuum system and shroudedDynabrade power tools. We have beenmaking progress in shrouding a numberof our tools. We currently have one partnumber that has NOT been released andthat is a 50570. It features a 3" (76mm)vacuum shroud as you can see (Figure1.), also see new product report (pg. 2).

Other tools are in prototype statusand can not be requested for trial fromour sales group. Dynabrade does havetools testing right now, but these toolsare not close to what can be considereda finished product for release.

We do believe we are putting ourbest foot forward and that we areoutshining other power toolmanufacturers. There are a number of

very large quotes out there (someexceeding several hundred thousandU.S. dollars) and we are doing our bestto address those. This article is toprovide awareness of an emergingmarket and what we are doing toaddress it. There will be updates to thesales group as we move forward.

Recap of a visit to a windmill manufacturer. Presented by our contributing author Jim Tischler.Trimming/Finishing a Blade ➤

1

Flashing needs to be trimmed from the leadingand trailing edges of the turbine blade. Rootend flashing is thicker and thins out toward thetip end. (View is from the root end to the tip)

Operator using our 52537 cutoff tool plungesthe diamond wheel into the flashing and beginstrimming at the center point of the blade. Thematerial thickness is approx. 3/8” (10 mm) atthis center point.

2

A view of the blade’s flashing from the center ofthe blade toward the tip end. The turbine blade’sroot and tip ends are placed into a rotator so theoperator can place it into proper position whenfinishing the surface, or edges.

3

Operator continues to cut flashing. Ourshrouded tool is very effective at dust capture.

4

The trimming was stopped to show the flashinghanging from the blade. Please note theremaining nib length on the edge of the bladeis approx. 3/16” (5mm). Nib now needs to beground off to finish the edge.

Dynabrade tool 50304, outfitted with vacuumshroud 52303, is used to finish the edge. Theoperator was impressed with the dust capturecapability of this tool. The blue tape and edgesare ground off.

Discover the Dynabrade Difference!

In this account, both operators that tested ourtool rated it as excellent.

What They liked:

➤ The cutting ease and vacuum capability.

➤ The 3/16" (5 mm) nib length left behind after trimming the flashing. The consistent amount of nib length decreasedthe work time necessary for them to finish the blade andwill eliminate an operator from their process.

➤ The operator’s current flash trimming process involves two people to cut off the flashing. One person knocks the flashing off (leaving varied size jagged amounts of material

along the edge) with a hammer and another person usingan Atlas Copco sander grinds off the remaining flashing.

This wind turbine blade manufacturer customerimmediately discovered the Dynabrade Differenceduring their tool trial.

PDR – Product Development Request.Progress to the process, presented by our contributingauthor Larry Van Deusen.

Update ➤

In an effort to revamp the PDR system, we are starting by going through all the open PDR’s to see which are still valid inquiries. There are over 120 “In Review” requests dating back to 2003. Some of these were acted upon without updating their status, and many may no longer be relevant. We are contacting the individuals that submitted them and if there is still a need we will evaluate and prioritize them. We will be utilizing “Global Product Outreach” surveys when we would like a broader understanding of the need for a product, or would like

additional input on features needed. As this is being done, we plan to revamp how new requests are handled, both from the entry form, and the internal procedures used to process them.

Even with the existing system, we have received 16 new PDR's since the last DynaPulse, so we know this isimportant to you. Please be patient while we improve thisprocess and eliminate the “black hole” image of this program.Your ideas are important to us, and we need to keepthem flowing!

Repair Notes & NewsInsights into repair concerns and processes

Proper tool selection for a specificjob could be the most critical stepin ensuring the tool will satisfy theend user. Presented by ourcontributing author Irv Roy.

Right Tool for the JobSize Matters ➤

In the May 07 Issue of DynaPulse,the article "Dirty Air, No Oil" highlightedthe importance of preventingcontaminants from entering an air motorthrough the air supply. Another veryimportant way to improve the life of anair power tool is to properly match thetool to the work. Tool design, thespecific application and the manner ortechnique that an operator applies whenusing the power tool will all have aneffect on the life of the tool. Thetechnique must be correct not only forthe application but also for the durabilityof the portable power tool. When a toolis not properly matched for anapplication, or when an operator usesincorrect technique, tool performancecan suffer and tool durability will mostlikely become an issue.

Consider Die Grinders asan example.

Dynabrade designs andmanufactures a variety of Die Grinders.Straight, right angle, 7˚ offset, etc. Inthese categories there are .4 hp, .5 hp,.7 hp and 1 hp air motors available.

Think for a moment; will a small.4 hp die grinder hold up as well as a1 hp die grinder when used in the exactsame application?

Obviously not!

The larger horsepower Die Grinderhas larger bearings and larger vanes

that will carry additional workload for alonger period of time. So, whenappropriate, or whenever possible use alarger more robust Die Grinder.

Now what about when there is a needfor a small compact Die Grinder to reachinto a difficult area, or the applicationcalls for finer detail grinding? The .4 hptool would most likely be the rightchoice. However, it is important to alsotake into consideration the operatingtechnique that will be applied by theoperator in a specific application.

Here are somequestions to consider.

- How should you use that .4 hp DieGrinder?- Should you plunge in aggressively oris it better to allow the speed of the DieGrinder and the burr do the work? The

second technique will accomplish thejob without undue strain on the smallerbearings and vanes that are used in thesmall .4 hp Die Grinder.

Also consider the style and size ofthe burr that will be used in the DieGrinder. There are a variety of burrstyles designed for working on differentmaterials. Some produce a very finesmooth cut; others are aggressive andcan be difficult to control.

Think about the effect that a verycoarse cut burr will have on thebearings and vanes of the Die Grinder.When using coarse cut burrs, or burrsdesigned for use on nonferrousmaterials and aggressive stock removal,mounting them into a small .4 hp DieGrinder will no doubt lead to earlybearing and vane failure.

Most complaints coming from thefield claiming “premature failure of theair power tool” or bearing failure are adirect result of misapplication of thepower tool.

So remember, ask yourself, “is thisthe right tool for the job?” Think aboutthe application. Think about how theoperators will be using the tool. If youdo this, you will be helping thecustomer avoid problems by guidingthem to the portable power tool that willbest enable them to accomplish theirwork objective.
