Jetstream Conspiracies

It doesn’t take more than a few clicks to be diving deep into websites of paranoia I can tell you.  One that comes up a lot is all about Jetstreams, and Jet trails (or contrails (condensation trails)), with varying, and conflicting reports of mass population control, mass population killoffs, biological weapon dispersal testing, weather altering and control.  The conspiracy theory is that the “government” is playing around with the position of the Jetstream, and using jet trails/contrails to seed clouds, or drop nasty stuff on the uninformed populations below.

What would all these conspiracy ‘experts’ think if they knew there were Multi-Jetstreams!!  And the government knows about them!!

(BTW – from my Navy days – the definition of an Expert:  an Ex is a has-been, and a Spurt is a drip under pressure.  Oh, and if you assume something, you make an ass out of u and me (

But Multi-Jetstreams are not a myth, nor a conspiracy – they are the latest development in sanding technologies by Festool.  By supplying, and exhausting air through many holes in the sanding pad of a sander (such as a Random Orbital Sander), you have rapid, dust free material removal, a significant decrease in sandpaper clogging which then leads to maximising service like of the sander, the pads, and the abrasives.

In addition, the airflow helps cool the sanding pad, resulting in the tool, abrasive and work surface being 25% cooler than it would without Multi-Jetstream tech.

Multi-hole technology

The holes in the sanding pad either provide or remove air depending on their position.  It is curious that there are more holes in the pad than there is in the paper – this is deliberate – air is also supplied below the paper, and all the supply and exhaust holes combine to maximise dust movement and removal as it is produced, reducing heat and clogging.

Supplying air is unusual – pushing dust trapped at the centre towards the outside where it is collected by the multiple extraction holes.  It is backwards compatible with older sandpapers, and new multi-jet paper can be used on old machines – obviously both scenarios do not benefit from the latest technology.

Don’t try what someone suggested on the Festool Owners Group website/forum – drilling extra holes in your current pad.  Sure, it might look more multistream, but there are internal channels leading to these holes in the legitimate pads!

This new technology is now standard in the Festool sander range, and both the ETS sanders and the Rotex will benefit significantly from the improved airflows and dust removal from the sanding surface.

I know they claim a marked improvement in minimising clogging of the abrasives, but I don’t know how it will work in situations that caused me the most clogging – burnishing with oil.  Oh well, you can’t win them all!
