Doug,

I have a original baffle design in my HF collector and it has been working fine.  The new Top Hat design is better and it can be used with your HF.

I would not use the expandable 4" hose from Rockler.  I have that hose for cleaning up around the shop but I would buy regular hose for my system.  I also think you might want to consider using 6" hose for the additional suction.  I am converting to 6" piping that you buy at HD or Lowes for AC.  I have seen a system that uses 6" with a dust collector like the HF.

I hope to make modification for the Top Hat design.  I currently have a baffle in my HF dust collector.  I recently bought a Shop Fox 3HP.  I will be using my CNC machine to cut the parts.  I think I will use Sintra (PVC) inside the Top Hat. 

Bulldo8,

You make an interesting comment about the smaller diameter baffle has higher rotation speed and improved cyclone actions.

My question would be why can't you use a 55 gallon container but make the baffle a little smaller?  The container is just a collection unit.  So you would get higher rotation and improved cyclone action but it would collect more material. 

Is the difference going to matter?

I am interested in building this but I have not seen the dimension for the depth of the unit.  Could you please explain.

Thanks

I am planning to use 6" pipe and flexiable hose with my HF Dust Collector.  Will I have a problem?

I am using it with my CNC machine.

Barry,

Innovative idea.  Hope it continues to work for you.

dbhost,

Thanks for the reply and the links.  It looks like my idea is just that an idea.  Putting the baffle is all I need to do besides adding a Wynn filter.  I am going to go with a 9L3000NANO which is taller and for the photos looks like I have to have a donut because of the mounting flange that comes with the filter.

I do have a question about the baffle.  It is difficult to tell from the pictures and I am not sure I picked it up from the write up.  The 120 degree strip should start on the left side of the intake opening of the dust collector collar so that the air is blown across the remaing part of the 120 degree strip or to the right of the opening?  I think it should be to the left.

Thanks for the help.

My question has to do with the space in the top part of the dust collector collar.  The part that the new filter is installed.  Once you have cut the MDF piece that will holds the filter with its hole in the middle the size of the filter, if there was a chute or cone that was attached to the MDF that holds the filter and extended to the open circle in the middle of the dust collector collar, would that help increase the efficiency of the unit?

I was thinking that if the opening to the lower section was the only air that went to the filter it would increase efficiency but I might not being thinking correctly.
