The quest of the Blade and the leaf blower? How to figure out blade resistance..



As you all know, blades on Floorball sticks - looks a bit different.

Many of them claim specific features, in different areas “like ball control” or “softness” and “color design” and so on.

Most of the blades sold on the market are seriously tested by the SP institute in Sweden to meet the requirements set up by the IFF and SP.

All good.

But some blades look very very different and are produced with different ideas and material on what and why - a Floorball blade becomes the very best one. All of them however have that in common that they are “ventilated”, meaning that they let through air and save both material and weight.

If now it is the case that the idea of a ventilated blade - mainly was done to increase speed in air... Then we have a question.

One of the most important features for any modern car is probably the fuel consumption, something that is measured very well.

Hmm, if a Floorball sticks most dominant feature is the speed through mid air? Should we not know then what blade that flies the fastest through air?

Do they test this? No. Do you want to know this? We do. Should not a manufacturer express this in their marketing with like a blade air resistance coefficient - maybe?

Or do you want to test this yourself?

This is an instructable on how to do this:

A) Make a jig-connection, maybe out of PVC pipe to easily attach the blade you want to measure.

B) This Jig must have a pressing point at a fixed distance from where you attach the stick.

C) This pressing point must connect directly to an electronic scale.

D) The jig-connection must let the stick rest on a free hanging hinge, so a stick at rest will hang straight down by gravity.

E) Take the very strongest leaf-blower you find at the closest landscaper (gas is more powerful than electric.)

F) Turn it on

Now see how much weight the pressure point put on the electronic scale.


Test all blades/sticks You have...

The blade with the lowest pressure on the scale is the blade with least air resistance..

Yes, but of course this is a homemade measure, but it should work fairly  - well as long as no-one else is doing or even reports the number of blade-air-drag..

And hey if you have some numbers in? well please share em with us... this also goes if U have a better procedure...

Caution

Research suggest that eye-injuries are more common in Floorball as compared to Tennis, but less common as compared to Squash (similar to Racquetball).
To minimize this risk of injury Floorballcentral recommend: Use certified protective eye-wear (mandated in many European areas for the youth). Do not lay down on the court. Follow the rules strict on stick height.

Also if you get addicted to this sport - do not blame us!
