Using the Pro-Beam Bender
By Randy Davis
Prior to 2013, the Pro-Axle Press and Pro-Rail Passenger tools were the only commercially available tools for bending axles. These tools work fine, merely have a few limitations:
i. Limited to zinc-plated steel axles – stainless steel and titanium axles cannot exist aptitude with these tools.
2. Dependent on axle diameter – the Pro-Rail Rider tool was designed only for axles with approximately a 0.086 inch OD (BSA size). If axles of this size are aggressively polished resulting in a reduced bore, the axles cannot be bent without the introduction of a newspaper or carte stock shim.
3. Limited to 1.5 and two.5 degree bends.
In 2013, the Pro-Axle Bough(1) was introduced as an elegant solution for bending axles. Not only did the tool resolve all of the above limitations, it likewise is much easier to use.
In the intervening years, I have used the Pro-Beam Bender to curve a large quantity of axles, and in so doing have learned a few tricks. So today'southward article will detail how to get the best use of the Pro-Axle Bender.
Effigy i – Pro-Beam Bender Parts
Tool Grooming
The body of the Pro-Beam Bender (futurity referred to equally the "Bender") is made from aluminum. Prior to associates information technology is tumble polished to soften the edges and create a consistent brushed stop. Unfortunately, the finish is slightly rough, so it can scuff an axle while information technology is being inserted into the tool. And then I recommend polishing the axle trough with some fine grit sandpaper.
1. Remove the thumbscrew and clamp.
two. Wrap a modest piece of fine grit sandpaper (800 or effectively) effectually the smooth shaft of a small drill chip (1/sixteen inch works fine).
3. Identify the sandpaper into the trough, and with medium pressure move the paper back and forth for ten-fifteen seconds.
4. Wipe out the trough with a soft rag and supercede the clamp and thumbscrew.
Figure 2 – Polishing the Trough
Next, applying a lubricant into the trough will assist preserve the finish of the axle. This should be done before each axle bending session.
If you plan to use Krytox 100 for your wheels and axles, you lot tin apply one drop into the trough and wipe off the excess. However, if you program to apply graphite, then I recommend a dry lube (not graphite). I employ Dupont-brand "Non-Stick Dry Film Lubricant" which you can detect at many locations including Amazon. The lube consists of Teflon suspended in booze. To apply, shake the canteen thoroughly, apply 1 drop into the trough, and allow it to dry (this takes just a few seconds). If too much lube is applied, just wipe it off with a soft rag.
Figure 3 – Dry Lubricant
Establishing An Angle
The Bender is equipped with indexing marks on the shaft to help identify the bend bending. However, the amount of curve is dependent on the type of beam, and somewhat depending on the spring that surrounds the shaft. And so before bending product axles, you volition desire to use a spare axle to constitute the desired bend. The Bender instructions include guidelines for various angles. In the setting column of the instructions, "Full" ways that the locking collar is at the top of the shaft, while the numbers 1, 2, and 3 indicate the index lines counting from the top of the shaft.
A few pointers for establishing the angle:
1. Start with a bend angle less than the desired angle. You can always move the collar further upward the shaft and bend the beam more, but yous cannot "unbend" an beam if the angle is likewise much.
ii. Always utilise an beam with no burrs or crimp marks on the shaft, as these defects could harm the tool.
three. The collar is locked with a 3/32 hex primal (not included with the Bender). Brand sure to firmly tighten the collar, but don't over-tighten.
4. The commonly used angles of i.five and 2.5 degrees are not magic angles. If the angles you institute are in the ballpark, you lot will be fine.
five. To decide the angle of a aptitude axle, you tin can use the nautical chart and information located Here.
The actual PDF chart is Here, just make sure to read the "Grooming" and "How to use the judge" sections before measuring an angle.(two)
Bending An Axle
i. First, mount the axle in the Bough with the axle caput centered in the cup-shaped indent. Y'all can arrange the axle forward or backward if desired, but centering the axle head generally works fine.
2. Tighten the thumb screw snuggly, but do not over tighten.
3. Place your thumb on top of the shaft, and employ your index finger to lift upwards on the angle lever. Lift until the tool stops. Do not squeeze tightly, as the spring could distort, resulting in a larger than desired angle.
4. Release the lever and remove the beam.
5. If the bend bending is not enough, move the locking collar slightly upward the shaft, and repeat the above steps.
Effigy 4 – Bending An Axle
The Bender instructions recommend marking the "12 o'clock" position of the axle head with a marker before bending. You can certainly practice that, but it does add a level of complication when inserting the axle into the bender. I accept constitute that the mark is not really helpful when mounting axles or aligning the car.(3)
Conclusion
The Pro-Axle Bough can profoundly simplify the task of bending axles. Simply if you take the time to properly setup the tool you will ameliorate your results which volition translate to better performance on the track.
(1) In tardily 2017 later this article was written, DerbyWorx introduced a new version of the Pro-Axle Bough. The differences betwixt the new version (Figure 4) and the previous version (Figures 1 and 2) are cosmetic and chronicle to manufacturing cost. Since the two versions are identical in office and usage, I chose to non re-shoot the kickoff ii photos for this article.

Humour
It's a sunny morning in the Big Forest and the Bear family are just waking upwards. Baby Conduct goes downstairs and sits in his small chair at the table.
He looks into his pocket-size bowl. It is empty! "Who's been eating my porridge?!" he squeaks.
Papa Bear arrives at the tabular array and sits in his large chair. He looks into his big bowl. It is as well empty! "Who's been eating my porridge?!" he roars.
Mamma Bear puts her head through the serving hatch from the kitchen and yells, "For goodness sakes, how many times practice nosotros have to go through this? I oasis't made the porridge yet!!"

My son and I are large fans of your newsletter! Here is a picture of my son's car from last year. We similar watching the Idiot box show, "The Flash" and thought, "How perfect would that be for a pinewood derby car." He wanted a fender car and then he made them out of balsa wood and used an old pinewood derby wheel with sandpaper glued to it to shape the fenders to fit the wheel. "The Flash" took first identify at the pack and district races, and was voted the den'south "Best in Show".

Pinewood Derby Memory
New Track Record
We take a "Sponsor" race after our Cub Sentinel race. Anyone can race for a donation of $100.00. The winner gets a big trophy and keeps it for a twelvemonth. It then has to exist returned to the Pack. This year, we had eleven sponsors.
I explained the pinewood derby to our minister and asked if she would like to race a motorcar. She seemed excited about information technology, and then nosotros congenital a iii-wheeled track passenger together, She worked with me polishing bores, using the concentricity approximate, etc. I proficient with her on being terminal to stage the motorcar, stay and lookout the car in case someone bumps it, etc. She became a master of it.
She won the race and the crowd began to cheer. She didn't know why. The Pack leader pointed to the big screen where it said, "New track Record". She said, "That's and so nice of them to tell me that".
What a lovely person she is.

Q&A
Q: Are in that location any weights that are more dense than Tungsten?
A: Simply a few metals are denser than tungsten. They are either very expensive, or are radioactive. Pure tungsten has essentially the same density every bit aureate, and is the densest metal that is practical for use as a weight.
The densest metals are shown below sorted by density. Prices for the heaviest six metals are current industrial (bulk) pricing. If these metals were shaped into a usable form (cylinders, cubes, etc.) and sold at retail the cost would exist considerably college.
Some prices were converted from troy ounces to Avoirdupois (mutual) ounces to maintain the comparison.
grams/ml $/oz Element proper noun
19.32 $1,170 Gilt
nineteen.35 $3 – $8 Tungsten (price depends on purity and shape)
19.84 $42,524 Americium (radioactive)
20.20 $i.48 Uranium (radioactive)
21.04 $80 Rhenium
21.45 $840 Platinum
22.40 $884 Iridium
22.60 $364 Osmium
Q: I read with interest the analysis of the Air Guides that fill the within of the wheels. Two questions:
A) In a rail riding state of affairs, does the Air Guide hit the guide rails?
B) With the deflectors glued to the body, how practise you apply a gap tool to gear up axle body gap?
A: Thanks for your interest.
1. The Air Guides have an inset which is oriented to the lesser of the wheel, and then the Air Guide does not touch the guide rail.
ii. You take to eyeball information technology. You can get reasonably shut past noticing the spacing betwixt the axle head and the outer cycle hub. Note that the gap measure has only a trivial effect on performance unless the gap is extremely small.
