Cyclone build

folk I decided that I would finally build my own cylone, I decided to do the bill pentz design and followed the build shown in the below link

http://www.ablett.jp/workshop/cyclone2.htm

some of the flanges I have done for the cyclone.

Next week I will get some 22 gauge GI sheet to make the cylinder

BTW I am using a 2HP 2800 RPM motor and a 14inch dia impeller from the bill pentz site (I have asked vishnu to laser cut the impeller parts )

Thats it folks thanks.

Hi Irfu,

Thats really nice. Working on the Impeller and want to see them in One piece before i start them. Nowadays i think you working a lot buddy. I think you can have 2 inlets so you can use them paralley when you finish your Mechmate build.

That's great Irfan. I wanted to build one too but there was so much info on Pentz's site, I couldn't plow through it all. I finally gave up and just ordered one from Clearvue. I applaud you.

Folk's thanks for the thumbs up,

The cyclone I am building is a 18 inch dia one.

Today we are celebrating Eid, so work will start next on Monday and meanwhile I am finalizing BOM for my Mechmate and me and Vishnu have finished finalizing the electrical BOM.

Irfan,

Here is a thread - with many photos - from a woodworking chatboard on how to build a Pentz cyclone:

thankyou nils - if you observe - i got the intake on the wrong side (if compared to bill pentz design) the guy who made me this screwed up!

anywayz I just had to reverse the direction of fins for the impeller and the motor. simple fix.

I got a 3hp 3 phase motor new for USD 120, now to get the impeller welded and balanced.

Following Irfan's last post about the "wrong-handed" construction of his cyclone, it occurred to me that cyclones in the southern hemisphere should be constructed for reverse air flow. Anyone remember the G.G. Coriolis Effect from physics class ( http://en.wikipedia.org/wiki/Coriolis_effect )? While I doubt it makes much actual difference, the air flow should flow clockwise (when looked at from above) in the northern hemisphere and counter-clockwise in the southern (just like water going down the drain).

For the induced cyclone, Uncle Coriolis will have no noticeable effect.

Where Coriolis does affect us woodworkers, is in the twisting of planks when they dry out. Equatorial timber doesn't twist as it dries, but our average sawn timber twists opposite to yours in the northern hemisphere.

motor mount frame -

here is my motor mount frame - where you see the bolting will also have rubber bushes. It will be mounted on the wall vertically.

any comments and suggestions are welcome -

also how to wire the starter - can anyone help me here by drawing a sketch on the starter picture.

A 6 A MCB is not shown.

Folks I need some help - I was originally intending to mount the blower vertical - but now considering the weight of the impeller with center hub being around 10 Kilograms - and mounted direct on the motor shaft - I am sort of afraid the impeller may come out of the shaft -? while running -

do you folks think I can still mount it vertical as in Bill's design - else will just mount it with the motor in horizontal position..

any inputs are welcome.

How did you plan on attaching the impeller to the shaft? A grubscrew would not be enough. "Taperlocks" would be good. If your motor shaft has a center thread, this can be used for a safety washer to prevent it from falling off.

Watch out for an excessively heavy impeller - it puts a high starting current on the motor for a long time and your circuit breaker may trip.

Irfan, Can you use a pulley drive and mount the impeller its own shaft with bearings to take the load?

A 10kg (22 lbs) axial load is not worth worrying about. . . . . . . unless it falls off.

Yes G' my motor shaft has a center bolt with 8x8mm key to drive - if the load is heavy then I will go with star delta - one of my electrical colleagues promised me to design a start delta using 3 contactors, a load relay and one timer.

the MCB I have is a 6 AMPS one.

I will mount it vertical - lets see what happens

Irfan,

I was just telling my family how impressed I am with your progress on this cyclone. I wanted to build a dust collector using the information on Bill Pentz's site but didn't have enough patience to wade through all of the verbiage on his webpage. Not only are you successfully doing it but you are doing it in a foreign language. My hat is off to you!!!

It must feel weird having built a machine that can help build its own upgrade parts and support equipment.

It starts with a dustfoot and will probably end up making another MM.

You probably only have to worry when you leave with one in the shop and you come home to two of them.
