Brownline TrackS

Brownline Seat/Cargo Track – Drill Bushing

We receive request from customers frequently. One such request came in a few weeks ago.  A customer wanted a drill bushing he could used as a guide for drilling Brownline Seat/Cargo Tracks.

We have been manufacturing Special Aircraft Tools for almost 20 years.  From time to time, we receive inquiries if we have made or would consider making “specific purpose” tool.  What customers want and what specific application could be made easier or more accurate with a “Special Tool” is always of interest. Improving quality is always top of mind.

Brownline and most other manufacturers of seat/cargo tracks manufacture the tracks to Military Specification MS33601.

Solving a Customer Problem

The problem is to drill a pilot hole in the seat/cargo track extrusion base, concentric with the 1.0” spaced holes machined in the top of the track extrusion.

As it turns out, like most jobs, this task can be simplified by employing a drill guide.  So, to solve this problem we propose a “Drill Bushing” with an Outside Diameter to fit in the machined hole.  The Inside Diameter is 0.1285” (to accommodate a # 30 Drill) .

Specific Purpose – Specific Solution

Brownline Seat/Cargo Track Drill Bushing

This drill guide, when used, will ensure the resulting 0.1285” pilot hole in the extrusion base will be concentric with the machined holes in the top of the seat/cargo track. 

With the initial pilot hole drilled, the next step is to properly size and countersink the fastener hole to the installation specifications.

Seat/cargo track drill bushings , is machined from O-1 tool steel. Each bushing is heat treated, tempered and engraved on the head. Machining of the these drill bushings is within a tolerance of ± 0.001″.

Machining Ideas into Finished Parts

In conclusion, we propose to machine a test production run to determine if there is an adequate demand for this tool.  Interested in adding a Special Tool to your tool box? Please let us know . We would appreciate your comments and feedback.

Drill Squares – 3 Sizes

Choose the Drill Square size that’s right for your application.

Special Air Services-Canada Inc. has been manufacturing Special Tools for the Aircraft Industries for more than 20 years. During this time, we have accepted customer suggestions and requests for tool designs and custom sizes. So, when designing and manufacturing these Drill Square, its only logical to manufacture and market what customers need and will choose to buy.

Here are a few photos of the three sizes of Drill Squares we produce.

We now Offer Drill Squares in 3 Sizes

  3. Drill Square P/N 9536814-401 (Dimension 1.5″ X 1.0″)

Heat treated tempered and polished

We machine each Drill Square from 1/2″ thick O-1 Tool Steel. Then we heat treated and temped each Drill Square . The heat treating and tempering produces a very hard and scratch resistant tool. Typical hardness is about 59 on the Rockwell C Scale. Each Drill Square then polished.

Drill Square Selection

Firstly, Drill Square P/N 9536814-201 is the most common and typical choice for most customers. It offers the longest length on the 2.0″ leg to provide the maximum guiding surface when drilling. It works best with diameters larger than #10 Drill size having a flute length of over 2 inches. The longer length offers better accuracy. Furthermore, the shorter leg (1.5″) works well with a smaller drill like a #30 or #40 drill. We call this one the Standard Drill Square.

Secondly, to satisfy a request from a Maintenance Repair Overhaul (MRO) operation, we designed Drill Square P/N 9536814-301. They wanted a shorter guide leg to work with smaller diameter drills like a #30 or #40 Drill. These drill sizes typically have a flute length less than 2 inches. This MRO purchased enough Drill Square to provide a Drill Square to each employee working in their Structures/Sheet Metal facility. We call this one the Medium Drill Square because of its compromised leg lengths.

Lastly, based on our own experience, we designed Drill Square P/N 9536814-401. We wanted a Drill Square to use in tight spaces. It was designed in an effort to accommodate the shorter flute lengths of stub drills, usually chucked in an angle drill. We call this one the Stubby Drill Square because of its compact design.

Drill Squares – 3 Sizes Another Lifetime Tool

Like all the tools Special Air Services-Canada Inc. manufactures, we select materials and produce designs that are functional , resist wear and abuse. Craftsman who originally chose our tools almost 20 years ago still used them today. If you see any of our tools in a professional’s tool box, ask him what he thinks of the quality and functionality of our product. In short, we are sure you will only hear good things. If on the rare chance someone has a suggestion or says “I wish SAS Canada would have made it differently”; have them contact us. Above all, as the end user, we truly value their opinion.

Machining Ideas Into Finished Parts

Transferring Fastener Holes

The Task:

So, you have been assigned the task of Transferring Fastener Holes from an old or damaged sheet metal part to a new replacement component. To be accurate, you need to ensure the hole on the new parts are concentric and precisely located with the fastener holes in the older component.

For some technicians, simply using the old component as a drill guide seems adequate. For some application this may be acceptable.  However fastener holes in the old component, may be oversize or elongated .

Therefore, you may unintentionally copy the inaccuracy to the new component.

The Solution:

However, if you want to maintain accuracy use a “Transfer” Drill Bushing. This will ensure the new fastener hole is accurately located and concentric with the desired faster hole location. 

We specifically designed our 27 Piece OD Drill Bushing Set to assure the accurate transfer of holes.

27 Piece ID Drill Bushing Set
27 Piece ID Drill Bushing Set

27 Piece OD Drill Bushing Set


Subsequently, the location of the fastener hole is transferred using this drill bushing as an aid . The bore of the Drill Bushing accurately guides a “pilot” drill through the new component.

Transferring Fastener Holes

We have designed the OD (Outside Diameter) of each Drill Bushing to accommodate fastener diameters used in the aircraft industry. The Drill Bushings in this set fit standard, oversize and under-size fastener holes.

Drill Bushing with an OD of 0.1875″ or less, have a bore machined for a #40 pilot drill size.

Drill Bushings with an OD greater than 0.1875″, have a machined bore for a #30 pilot drill size.

Now the Pilot Hole is Drilled:

With the pilot hole accurately located and drilled in the new component, it is time for the next step.

The next step uses standard drills, step drills or even reamers to finished fastener hole diameter.

The application’s specification may even require a combination of hole-making tools.

16 Piece Slip Fit ID Drill Bushing Set

2018-10-27 – Now Available

For a number of months, we have been offering our 5 Piece Slip Fit ID Drill Bushing Sets (Internal Diameter).  So, based on requests for more choices, from our customers, we have  manufactured a 16 Piece Slip Fit  ID Drill Bushing Set.

A need for more sizes

In the past we had manufactured the 5 fractional sizes as our 5 Piece  slip Fit ID Drill Bushings.  These are in stock and available from our online store:

https://www.sas-canada.com/store/slit-fit-id-drill-bushing-5-piece-set/

Our custom have expressed a need for even more sizes and suggested internal diameters to accommodate specific fractional, numbered and lettered drill sizes used to drill faster holes in the aerospace industry.  The requests have come from individual technicians and also from Maintenance Repair and Overhaul facilities.

Finally, after determining the corresponding preferred drill sizes, we came up with a set of the most common and most requested drill bushings.  Select the link below  for a PDF listing of the resulting sizes .

16 ID Drill Bushing Size

We have now completed a production run for the total preferred Sixteen  sizes.

New Tray Design

First of all, we designed a new tray to accept the 16 ID Drill Bushings,  the most requested sizes .  As you can see (in the photos below) the new tray is similar to the tray supplied with our 27 Piece OD Drill Bushing Sets, offered for the last few months.   We have chosen “Red” as the anodized color to make the tray highly visible in you tool box or while working near aircraft and components.

Hence the new design produces a practical compact tray.  The respective bushing ID size is engraved below each bushing receptacle .  Making it easy to return bushings after use. Therefore, this feature assists in tool a management systems.

Same Quality – 16 Piece ID Drill Bushing Set

Above all, we strive to maintain the highest quality.  Our 16 Piece ID Drill Bushing Set is machined from Precision Ground O-1 Tool Steel sourced from a Pennsylvanian USA supplier .   Furthermore, we maintain a  tolerance of ±0.001” .  After turning, we heat treated and tempered the bushings.  This produces a hardness of 60+ on the Rockwell “C” scale.  The ID size in decimal notation, as well as fractional, number or letter notation, as applicable; is laser engraved on the bushing head .

We primarily used this machine to assemble aircraft control cables

This lightly used swagging machine has served us well over the years.  We have scrupulously maintained it during that time.  The machine is currently in storage.  Although there is some dust accumulated on the surfaces, there is no corrosion evident or visible.

When the City of Edmonton closed the downtown airport about 5 years ago we were forced to move to a smaller shop.  The unit was placed in storage at our new smaller location, but due to space restriction, we never set it up after the move.  We have now decided to sell the complete kit.

Also available is about 250 individual MS and AN aircraft cable terminal ends which are in our current inventory; a $1,000.00 plus value.

Also used for Marine Cables

Over the years we also assembled many marine, sailboat cables.  Most of the cables terminal ends used in the rigging on sailboats can be readily swaged with this machine.

The weight of the complete kit is about 240 lbs, so truck transport or local pick-up are the only freight options.

OD Drill Bushings – Now Laser Engraved

Laser Engraving the OD Drill Bushings

As we have stated in the past, we are attempting to provide useful, durable and professional tools for the Aviation Industry.  These tools are also used by professionals who take pride in their precise work.  OD Drill Bushings Now Laser Engraved.

Improvements with each production run.

Sample of Laser Engraved OD Drill Bushing OD Drill Bushings Now Laser Engraved
Sample of Laser Engraved OD Drill Bushing Head

We have been manufacturing drill bushings and other drilling aids for over a decade.  With each new production run we attempt to improve on the previous release of a particular tool.  Therefore, to meet this goal, we have improved the “Tried and TrueSAS-Canada Outside Diameter Drill Bushing design.  Since the initial release we have employed  our CNC milling machine to mechanically engraved the  outside diameter on the head of the bushing.    On the current release of drill bushing a laser engraver is used to apply the  diameter and other text .

No Big Deal you say…

ID Drill Bushing Tray – Back from Anodizing

Its taken a little while to get to this point. So, the first  ID Drill Bushing Tray was picked-up from our anodizing sub-contractor today along with 30 plus identical trays.  Behold; Bright Red, Shiny and New.

A little while back, we made a decision to have all future aluminum components anodized.  This process adds a decorative and professional surface protective finish to our quality products.

ID Drill Bushing Tray
ID Drill Bushing Tray For Both SAS-Canada Threaded and Slip Fit “Doweled” Bushings

What’s the big deal.?

Well…    maybe to some it isn’t.

But it is for us !

The ID Drill Bushing Tray

I have worked in the aircraft industry for 40 years. Over those years I seen many highly skilled craftsman deal with Drill Bushings they have acquired from used and surplus markets.  It seemed like they “made do” with what was available rather than a source that considered their access to a real aid to help them be a better craftsman.  Sure there are lots of suppliers out there of these kinds of tools, but I never felt that the tool was designed and intended for a craftsman in the aircraft industry.

We have been  manufacturing Drill Bushing Sets  for about a decade.

It all started about 10 years ago, my son who also works in the aircraft industry as a Licensed Structures Aircraft Maintenance Engineer came to me and asked if I would make a set of drill bushing to satisfy his reasonably complex requirements.  At the tine I had just acquired a CNC lathe which was part of my technically expanding company.

I took on the challenge.  With his suggestions and our combined experience in the field, we came up with a set of 27 different drill bushings.  The initial run was for 10 sets.  A total of 270 individual bushings.  We then designed and machined a tray from 6061-T6 aluminum extrusion. Much like you see in the photo above and the copy of the drawing of our 27 piece Drill Bushing Set shown below.

 27 Piece OD Drill Bushig Set
SAS-Canada – 27 Piece OD Drill Bushing Set

Together we began to offer these sets to our co-workers and associates. It took a little while for the first 10 sets to sell.  When we ran out of inventory, we made subsequent batches as there was vacant time in our CNC machining schedule.  We have shipped these sets all across Canada, throughout the USA and as far away as New Zealand. Now we find it hard to keep up with demand.

So… to get back to the title of this post. This is the first step in the launch of a new group of product we feel is needed and has potential to offer an organized and simple component of a drilling tool system Special Air Services-Canada Inc. intends to offer over the next few months. Stay tuned for more announcements.

We are a small shop and some days it feels like we are carrying water uphill with a hole in the bucket.  We hope to soon plug the hole in the bucket.  Does anyone have a couple of MS 20470AD10-10 rivets (they are big holes) and lend us a gun and bucking bar large enough to handle these rivets 😉.

We are working to replenish our inventories of needed tools to a manageable level.  That way you won’t see the “Out of Stock” on items in our online store, as you might find today.

Drill Block – New Design – In Stock Now

Drill Blocks In Stock Now

In early January we announced a new production run of the SAS-Canada Drill  Bushing Block.  We thought we would let you know; we just received the entire run back from the heat treating shop where they underwent  the Liquid Nitriding process.

As you may know this process “case hardens” the tool and results in a shiny black color providing an improved resistance to surface corrosion and scratching.

9536721-300 Drill Block Newly Designed

 

Added New Design Features

We have incorporated some subtle new features to the design .

Stainless Steel Set Screws

stainless steel set screw has been place in each end of the Drill Block to provide a positive hold on the slip fit drill bushing.  These set screws prevent the drill bushing from falling out during handling. It also is an effective anti-rotation stop during use even if the drill is clogged when the drill is withdrawn from the Drill Bushing.

Drill Block|Drill Bushing Block|Drill Bar|Snatch Block
9536721-300 Drill Block – Bottom View showing “V” Groove

“V” Groove in Base

The second new feature is a “V” Groove machined into the bottom surface of the Drill Block.

  • Firstly the “V” groove lightens the tool
  • Secondly, this tool can now  be used to drill a perpendicular and centered hole in a cylindrical component by placing the “V” Groove against the cylindrical circumference of the component.

A good example where this feature would be really helpful…  to drill the rod end fastener holes in a flight control push rod.

Optimizing Drill Block new features

IN STOCK NOW!   5 Piece ID Drill Bushing Sets designed to optimize these design changes.
