Masonite with the smooth side down as the air ramp goes from the top of the inlet to the bottom. Siliconed it to the side of the drum and used two self tapping screws to fix it to the top & bottom of the inlet

I am as happy as a pig in sh**. Connected the cheapie up this morning and no visible dust or chips go to the extractor. On the 6" pipe to the extractor there is some fine MDF dust at the cyclone connection. It works- tested 30 litres of dust - no loss of suction and no leaks with the cyclone

Ivan the "plastic" used in the USA cyclone is as smooth as a babies b** - I don't think ply comes close. I would be worried if the cyclone effect would be created - Friction could come into play but that is a pure guess. I have no metal working skills and using a jigsaw I have butchered the...

Paul charwood have 4" Y pieces for £6.50??

I completed the cheapie cyclone today - putting the inlet into the barrel - the air was blue much silicon and filler. It must be easier to cut it from a flat sheet. I remember Dave L had the same problem when making his cyclone but at least he was using thinner sheet. Then fitted the air ramp...

That sounds good to me. Just did not think about it How any bits of ply would you use??. Just thinking of air leaks If you are forming it from sheet metal you make 3 circle jigs to bend the sheet over.

Ivan if you had to make them out of MDF(assuming you did not have a lathe) that would be 41 pieces of 18mm MDF to cut outer and inner circles for. I would rather count sheep - good night.

Ivan prey tell how to you fashion a cone in wood???. The cylinder I have no problem with. I take it that you have a large steamer??. I have enough problems making entries and exists from metal to pipe with MDF - the band saw works overtime and often I resort to the router. What I am trying to...

Mike I ran soil pipe before I went to the Pentz site and was not about to upgrade as I have had no problems using blastgates at all ends then going to clear flexible to the machines. I have not got a thicknesser(yet) to test it fully. Mine works fine with 2 blastgates open at a time.

Yes that's what is using up most of my time. - the cyclone is just for fun. At present I have no neighbor on the side where my workshop is so I can usually get in a couple of hours each morning early. My list just gets longer Barry

Julian I have had no time but hope to find some tomorrow This is where |I am at Just did a mock up - its bigger than I expected. I will need to get more 6" flexible hose to reach the top from the extractor. If I built a 18" diameter one I would have to use a smaller collection bin and...

As part of my research to cheap cyclones I went to CCL who are into ventilation and air movement products across the country and asked for a bespoke conical reducer from 450mm to 150mm with a length of 738mm and to add a piece of 450mm body of 542mm. This is exactly to Bill's spec. I got a price...

Inspector I am already using 2 .5 micron filters each of 20m2 on my extractor. I am using Bill Pentz's spread sheet for the dimensions on my cheap cyclone and am making a air ramp as well. What I am trying to do is use easily available parts so that just about anybody can make one. Bill also...

A mini cyclone will help your henry as about 95/98% of the chips and dust remain in the capture drum of the cyclone so the vacuum does not get blocked and works better. I use mine on power tools and at the bottom of the router table attached to the router. I have run +/- 15 meters of soil pipe...

Julian check if the impellor on the Charnwood is metal - most these days are plastic - a no no by Bill's standards. I paid £150 delivered ( or was it £165) for a 3HP dual extractor on Ebay. Keep looking Barry

Thanks Dave and Paul - this is just mark1 so let the testing begin. Dave you know the hassle it is for a woodworker to build a cyclone - I have opted for the woodworkers option - the metal works would not be happy. I have applied three times at my local college to do the welding course but not...

Julian if noise is a problem build yourself a baffle With your existing situation why not use a mini cyclone - it will give your Henry a break and improve the suck or If you require further details PM me Barry

Not enough time today but I got the cycliner and cone attached just the input and ramp to do

Sorry I did not get my mark one version of the cyclone completed today - got side tracked - had to make a wall cabinet first but this is were I am at I have completed the collection bucket on casters and the Ikea cone has a 6" connection done and the air outlet to the extractor is...

Brad this is how the extractor makers get the motor to run at about 50% of its capacity - they starve them of air. I did tests with a clamp meter to see the amperages drawn with no bag, with the supplied bag and with the filter. With no bag the motor works best but is not practical. The filter...
