I'm currently glueing together my Cyclone Central 50mm cyclone and I'm measuring up SYS5 T-loc systainer lid for use as the deposit box on top of my CTL26.

Has anyone tried if a Systainer is tight enough to work as the deposit box and not blow to pieces under pressure?

How badly would making the hole reduce the strength of the lids support construction if punched through where the Festool text is?

I guess at least a plywood circle backer would be needed inside the systainer for the attachment screws?

I see you built an inner plywood container to the systainer - did you do that to withstand crushing forces on the systainer or to make emptying easier since the lid is hinged?

I'm just wondering wouldn't it be easier to make a systainer base clip compatible plywood box in the first place instead of cannibalizing a systainer for this if you need to build a plywood box anyway?

i tryed this with a sys 4 ( think)  and a sys2 . it didnt work well at all. there isnt a good enough seal between the lid and the base part to trap the air and the negative pressure pulls in the sides.
if i were you i would make a box the size of a systainer  and use that instead.

there is a thread on that mess i made on here somewher . i will see if i can find it.

Hi Reiska

I have a Dust Deputy which is exclusively used on top of my CTL26 (photo below). I bought it before I discovered Cyclone Central (or rather - they discovered me - their 100mm cyclone is fantastic).

I thought about using a systainer but discounted it on the basis of cost, suitability and difficulty in conversion. Instead I built a simple drop box from 19mm MDF. In order for my box to fit properly on my CT26 I made a small base frame (independent of the box structure) that fits into the recess on the CT26 and allows the locking clips to be applied. This frame (second photo) was then screwed to the completed drop box. The lid of the drop box is fitted with a lip, which improves the seal, but I have also helped it with a line of draught proofer. I have installed clips on each side (put on after the photograph was taken) to keep the lid and base together during movement. Finally, I made sure that the finished height of the drop box on top of the CT26 was 2mm lower than the standard 900mm height of my MFT3 and Kapex workstation and mounted the DD towards the back to make the area in front usable.

Total cost $2.

I am sure that the whole arrangement must be visible in some of my videos.

Hi Reiska

How have you got on assembling the 50mm Cyclone Central? Have you put in a pressure relief valve?

I use my 100mm one to intercept the chippings from my planing machine with a plastic dustbin as a drop box. I then put the shavings onto my compost heap which gives a perfect balance with the grass cuttings. I fork over the heap about once a week and everything rots down really well.

My local timber supplier allows customers to have free offcuts - the base frame cost nothing. The small amount of MDF was left over from another job where its cost had been factored - hence the $2 that I allowed. I think that Samer's cyclone is very elegant and shows some high craft skills but in the time it would take me to make one (and I would struggle to make one as good as his) I could turn several hundreds of dollars profit from routine work.

Peter,
You posted feedback on the Axi site (I assume it was you!) for the Numatic NVD750.  Do you still have this extractor and what is your opnion of it now?  I am in need of an extractor that I can use in a really confined space that I can hook up to a 100mm thicknesser outlet as well as use with power tools and this looks like it could tick both boxes.  I would love to have a Festool vac but they don't look like they could handle both tasks?
Cheers

Thanks for asking Peter, I think I finally got the cyclone itself airtight. I haven't put in a relief valve since I am under the impression that the small cyclones don't need it?

What I'm scratching my head with now is how to get it connected to my CT26 - the 50mm ports in the cyclone are just that much too large or small for both the 36mm Festool hose tool end and the 50mm vacuum connector.

Anyone figured out if any of the Festool hose ends would be a tight fit inside or outside these dustports?

Have to work, but will post text later. DD stole this concept from me and other early members of the FOG, it took us like an evening of posts to come up with it, Eric

Nice work Vinny, i wish i had done my lid like that

nicely done. i like the pull out box. very thoughtfull

Vinny, I did some tests today and my ct 22 without DD on Sys5 has more suction, BUT the ct 22 with DD on Sys5 has mad suction. I have a board that is marked that the ct 22 could pick up when I first installed the long life bag. The ct 22 with DD on Sys5 couldnt pick up that board, but could pick up one its size that was 1/2 instead of 3/4. Ive been using it for four years and never had a problem with suction, but if I did it again I would use that stock systainer part as Vinny did, keep sucking, Eric

this thread also seems like it would be a good candidate for the Systainer subsection
