No CT wings for me, I guess

Great solutions!

I had a few hours spare time in the workshop this afternoon and took up my vacuum project.

Managed to make a few prototypes.

For who is interested here's some pic's and a few video's. Sorry for the filming quality, I only have two hands.

Peter Parfitt: here is my version of the vacuum-bench-holder.

It is a box that holds itself to the bench and holds a workpeace.

[attachimg=2]

there is an adaptor for smaller peaces

[attachimg=4]

It really sucks

[attachimg=6]

You can easily change the pattern of the weathering strip when you use coated ply for concrete

[attachimg=7]

[attachimg=8]

[attachimg=9]

tried to film it:



It took a lot of force to move the peace of ply:



Next part of the project was a vacuum rail holder

[attachimg=10]

[attachimg=11]

[attachimg=12]

At first I wanted it to clamp the rail to the work peace, then I realized it would be better if it was able to slide in line. that could come in handy if you haven't brought a long rail.

Again a sort of filming:

That's all for now, thanks for watching

Hi Rogier

I say again - I think that your designs are far better than mine - well done. The idea of having the work piece clamp hold itself to the bench is so simple but so brilliant.

One addition that you might like to think about...In order to hold a guide rail in place why not use the channel on the underside. You would need to stop it off with a rubber plug (not sure of the cross section of the channel but about 10 cm long in order for it not to get sucked inwards) and a short strip of rubber at either end of the work piece that goes between the rubber strips under the rail.

By the way; You can damage an extractor if you do not allow some bleeding. I am sure that the CT Wings design takes this into account but I am not sure that Rogier's designs do.

Hi Peter,

Good point, the necessary air bleed, I am afraid that my hose automatically provides that.

And it is always possible to drill a small hole somewhere in the vacuum clamp.

And thank you for the compliment!

Wow what great ideas you have come up with Rogier. You are an insparation to me. So simple and good looking, love the fact the wall units fit in a systainer. Thinking in the system. Could you make one of your great systainer tops in to a vac clamp as well. [smile]
Thanks for inspiring and sharing.

That is awesome! A homemade vac clamp!! Brilliant. Thanks for sharing.

I believe that the CT's have bypass motors that have a separate fan for cooling and therefore will not over heat from blocked flow like cheaper vacuums that use the same fan for cooling and vacuum.

@bror, really smart stuff. Somebody posted a link on woodworking.nl. I hope it is royalty free  [wink]

Peter, adapting the rail like that, wouldn't that look an awful lot like the mafell aerofix? A nice product, but I'm looking for a vacuum rail-holder that I could use whenever I needed one. On any length of rail. Shouldn't get in the way when I don't need it. And be cheap.
Furthermore I wanted it to be able to slide forward without getting off track.

Hi Rogier

I am not familiar with the Mafell aerofix but just watched a video about it. Yes, that is the sort of idea that I had in mind except I would want to use the standard Festool track rather than a special one. The Festool guide rail has the rubber underneath which should act as a seal to the left and right of the rail. All that is then needed are seals under the rail at each end of the workpiece. This could be just a couple of small pieces of that non slip matting that you can see in the middle photo of my rubbish design somewhere up above.

Thanks, Slartibartfass, Alex, Kev, roblg3, Peters, GOT8SPD, RKA, Ollie, waho6o9, Roseland, andyman, overanalyze, Pip, Dongar, NERemodeling and bossie.

I've used the vacuum lifting jig four times in the last weeks, lifting tiles, opening a concrete lid and removing floors. It worked OK. Even with a fair amount of air-bleeding.

I've even used the bench-vacuum-jig a few times, I don't call my old Festool vacuum a spare any more.

I guess there must be a lot more possible uses.

Has any one got a (brilliant) idea for this new use of the dust extractor?

I'm all for sharing inspiration.

@bossie, thanks for the link alert.

@Peter Halle, take care and all the best to you

i was gonna buy 4 ct wings but after this thread im goona cancel that order and make my own lol

 

[wow]

Don

I don't believe this is true? EKAT only shows one motor/turbine that I can see? And I really can't tell if it has an external fan attached to that motor for cooling?

If I am wrong about the bypass motor I'm sure someone will be quick to correct me. Whether I am wrong or right, I don't want misinformation to cause someone to damage their CT. It's wise to be careful to not wreck your CT if you intend to use the vac clamp for extended periods. A small bypass gap ought to do the trick?

I am sure that getting as much suction power out of the CT to lift blocks and so on is going to risk a burn out unless bleed valves are built in. Now which FOGger has the knowledge to work out just how much 'bleeding' will be needed in order to be able to protect an extractor? Will those calculations work for every extractor in the range?

I think that Rogier's ideas are brilliant but they are not for the faint hearted.

I would think that looking at the CT wings would be a good place to start. Whatever they use for a bleed opening there ought to be a clue, shouldn't it?

 

[Stone Message]

Hi Wow,

The more I think of this the more I think that a home made CT based vacuum clamp is too great a risk. I am already one of the naughty ones who uses a Dust Deputy (risk of static discharge destroying the CT) but I think, after seeing the information above, that I will give up any ideas of such a clamp.

I hope that Festool HQ are aware of the great design ideas that Rogier has demonstrated and feed this into their design team.

Hmmm... it occurs to me that with these truly nice helpers, you would need to dedicate the vac to the helper, and need another for the machine unless you're going to do some handwork. I wonder if it works with wet-dry vacs.

I don't see any reason why it shouldn't? In this case, I think a vacuum is a vacuum. It's simply the suction that the machine produces that we're after. The Festool DE's might well produce more vacuum than a shop vac - I don't know. But as long as the vacuum produced is adequate to the task, I would think it would be fine.

And it would be a lot cheaper to learn a lesson with a shop vac than with a DE...if such a thing were to occur.
