The Dust Hub - How to get the most out of just one CT - Video

[wow]

Peter, I know it would have made it a bit more complicated but did you consider putting microswitches on the blast gates and using them to control a relay for power to the devices.

It would be a bit more involved to build, but - as I think you Brits say - a 'treat' to use. I have a dedicated dust collector in my shop so it's less of an issue, but if I were to copy your design I expect that's the way I'd go.

Excellent idea Peter. For those in the uk who want Y fittings instead of T junctions. Our standard rain water pipes and fittings are the same size as the axminster kit in this video.  [smile]

Bit technical for me - but a great idea.

You learn something every day - many thanks.

Looks a very neat idea Peter. Had you considered putting a Cyclone inline as you are spitting hoses anyway. It would quickly pay for itself as it would save on  the extractor bags.. Geoff

Hi Geoff,

Yes, I have a Dust Deputy which does save a huge amount on bags. It is fine in a workshop although static build up is a risk.

I will definitely setup a Dust Hub when I get setup in my shop. I'd like to keep it antistatic so I'll research this aspect, I like that the Hub is centrally controlled both for the blast gates and the power to the tools..

Not that complicated electrically. If there were enough interest I could draw up a schematic and parts list. It's something that would be pretty easy to build as long as you can solder a wire.

There is a great PC board prototyping product that originated in the UK. It is commonly known by the name of the original product Veroboard, which is a trademark, in the UK, of British company Vero Technologies Ltd. It makes stuff like this rather easy for one-off prototypes.

Hi Wow (is that your first name?)

I am very familiar with Veroboard. I have also acid etched my own circuit boards after using photo resist and earned money in my  designing multi layer printed circuit boards but...

The whole idea of the Dust Hub is to provide a simple solution that is easy to make and well within the skill set of the average person. I would be delighted to know that some would want to take it above and beyond with micro switches and so on.

I think your offer to draw up some plans is brilliant as it would allow everyone the opportunity to upgrade to the "Super Hub".

In the mean time the anti static needs to be cracked and Preferrablywood (yes that is his first name - what were his folks thinking of?) is doing some research.

Many thanks.

Peter

 

[wow]

WOW are my initials, but it's also the way many people know me. I go by that just as frequently as by my first name.

Let's see if anyone wants to bother with the 'Super Hub' idea before I spend any time or effort on it. Could be my idea is a solution in search of a problem...

Sounds like a good idea Bill.

Peter

 

[Scott B.]

While some of the ideas here are solving problems that don't really exist in my workday, the one that I agree completely with is about reducing the amount of bending down.

This has been a good way for me to work...

Really nice job Peter!

I remember there were some serious issues with the Dust Deputy not too long ago. Like frying the electronics in the vac due to static discharge, if I have that right. There were various solutions offered to make the connectivity sound right to the vac.

Sorry I don't have a link to the threads.

Cheers,

Peter

Hi Peter

The problem appears to be caused when static builds up on the non earthed plastic parts of the DD etc which then discharges through the electronics of the CT. Solutions range from running copper wire down the plastic and contacting it with the Festool green hose, using copper tape, buying an expensive solution from Oneida or just taking the risk.

At the moment I am taking the risk but I will address it soon. I did have a reel of braided copper wire (used for aerials) but I cannot find it so I may have to buy some. My plan would be to wrap it in a long spiral along the length of my plastic piping, around the DD and then earth it to an earth point inside the Dust Hub. There will be no need to make direct contact with the CT as the earth in the Dust Hub will be fine.

Hi
  Please take seriously the subject of static discharge. As i am sure you are aware the consequences can be more than damaged electronics.
  Festool C.T extractors are designed for working with power tools and static discharge is taken into consideration during the design and any changes may effect the performance.
Regards
Phil

Sorry Peter, I don't understand "There will be no need to make direct contact with the CT as the earth in the Dust Hub will be fine."

What about the dust that is running through the pipe from the hub to the CT? Surely that is also a potential spot to cause buildup. For the small remaining distance involved why not continue to the CT?

Cheers,

Peter

Hi Peter

All the pipe work will be protected by an earth and this will include the DD. From the green Festool hose onwards to the CT will be covered by the Festool earth leakage device.

I will be making a video about it once I have the various bits of copper - and a bit of time.

In the meantime I would be grateful for more advice and experience from the vast knowledge base here on the FOG.
