Cyclone

That’s fine. I have another three backups

More in to the air for you to breath

My only compliant would be that all the fine and damaging dust will be blown straight through Henry

These compliances are buggers, aren't they.

Kim, Henry hoarding is 'a thing' you know?
Be careful!

well spotted, still a valid point if you can ignore the error

I'm keeping quiet. I moved Henry down into the workshop so that I only have George in the flat. Didn't want people calling me a saddo.

@hunter27
Try one of these for switching you vacuum on & off automatically.

I ordered one of these and it was delivered yesterday, I have been using it all day and it works brilliantly, thanks for the recommendation.

 

[dobbslc]

No problem

Looks really good!
I have been looking into this because I want to build one as well, and it seems that Bill Pentz has a load of good info on his website.
Saw him referred to all over the web, thought I'd share.

Yup, he is referred to regularly in woodworking and woodturning circles. I think I'm right in saying that he also did some tests that show cyclones ro reduce efficience but that doesn't take into account that they keep your dust filter pretty much clean; that's why I use one.

I looked at the Bill Pentz stuff a while ago, I believe he has a spreadsheet to work out the best dimensions for a given pipe bore and other factors. I wanted a 100mm cyclone and they were all stupid money, then Axminster started selling a steel one, so bought as soon as they came to market, I've just emptied the new drum for the first time, its a big un.

Originally I used a Axminster/Numatic NVD750 twin motor vacuum, it worked initially but now have a lot more ducting, probably about 30m and it wasn't clearing it properly, The NVD750 is a high pressure low volume vacuum, i needed a low pressure high volume so waited until I either spotted one on various auction sites, or Axminster had a sale. The latter came first so bought the Axminster AC153E which was £300 at the time, now £350. its a 2hp low pressure high volume chip extractor and makes a big difference as soon as you start putting up a bit of ducting.

You can see the 6" duct at the back, this leads to the workshop above, the cyclone stays in the semi-open barn so I don't need to use fine filters. The bag only fills if drum is full, that's how I knew it needed emptying.

Here's the duct upstairs, the switch to the left turns the extractor on. As the extractor has a NVR switch on it, I wired the on/off switch between the NVR and motor, this is better than bypassing the NVR as it also has a motor overload circuit built in. I was using an RF switch and remote on the old vacuum but I have heard some can be subject to interference and suddenly turn on, I don't want that happening while I'm out and about so I will swap it with a wifi controlled relay at some point so I can use my phone to control it.

And this is my first cyclone, still used on occasion with smaller tools. OK with a small Henry but anything bigger and it will collapse the drum.

Cheers
Andy

That's it brewd', just best any future builds.

You miss the point Kim.
A class M filters the finer particles
A Henry pushes them back into the air for you to breathe at your leisure

Excuse the mess. I have so much on the go right now. I’ll sort it tomorrow, honest!
I needed to finish the cyclone mostly today because the old Henry hose I had going to the top was crushing a fair bit when sucking so I picked up £10 worth of plastic pipe bits and made a new tube which is great and not so restrictive. View attachment 270609
Then to keep the hoover in place I put some little Packer blocks in place and made a Corner bit to retain it where it is. I can just lift it over if I need to get it out now which is nice. View attachment 270610View attachment 270611 All I need to do now is put some steel uprights on to secure the hose when I wrap it around the barrel. Also I plan on doing a switch on the side so I don’t need to keep switching it at the wall. I’ll have a little think before I do that though.

is that solvent weld pipe Kim

My hose ends have vents that can be opened and closed

Depending on the tool I'm using these can be useful. Sanding for example it's good to let a little airflow through as the inlet holes are blocked by the workpiece and gives both the machine and hoses an easier time.

I crack open another blastgate a little to leak a bit of air when using tools with small ID hoses, similar idea.

Hi,

For my small needs I've just bought a new Henry it's due to arrive tomorrow;

https://www.ebay.co.uk/itm/HENRY-HOOVER-NRV200-11-NUMATIC-COMMERCIAL-VACUUM-CLEANER-2021NEW-NRV200-C2-MODEL/251379065108?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

Like Kim I too have bought this cyclone it's already with me; it looks to have 50mm dia entries.

I already have one of these mixing buckets so today gave it a good clean out; it will need a lid but I've got plenty of sheet material; it's strong;

https://www.screwfix.com/p/ndc-poly...tr/7963k#product_additional_details_container

I'm looking forward to putting it all together assuming I don't get driven out of the workshop again with the freezing weather.

Kind regards, Colin.

I don’t actually do anything with mdf. If I do I will hear that in mind.

Yes it is. 32mm I think.

Yes they’re 50mm ends. You got the spacers with yours I assume? Do you want me to link the step down spacers that I used?
