I plan on making the same impellor mod to my HF.  I also plan to vent outside through the wall due to my location.  I believe I read somewhere here that venting outside would increase my amp draw and am concerned that adding the Rikon impellor might take it over the top.  Can anyone clarify or confirm for me? Thanks!

Hello everyone.  I've been doing a lot of reading here and have decided to build a top hat.  I have decided that I want to build it very similar to the one pictured. 
Question#1. I am a little concerned about the cone shaped portion inside the ring, whether it should be removed or not.

Question#2. Do I understand correctly that the outlet pipe should be elevated off the baffle a distance equal to .5 the diameter of the inlet?

Question#3.  I plan on incorporating vane style air straighteners inside the outlet pipe, but I can't seem to find any info as to roughly how long they should be.  Due to height restrictions I would like to mount the blower direct to the separator, so there may not be a tremendous amount of real estate in the outlet pipe.

Anyway yall,  I really appreciate any help.  I am not necessarily  intersted in building the most efficient separator possible.  But I am willing to but in a reasonable amount of effort for some reasonable results.  I just don't want to get too bogged down trying to build a finely tuned machine.  I certainly don't mean any disrespect to those that have or strive too!  Lord knows I wish I had the time to as well! 

Thanks!

How's it going fellas?  I am a hobby woodworker that migrated over from the welding trade.  I have recently moved from my two car garage over to my new shop and am interested in improving my HF dust collector with a top hat and am looking for ideas.  Anyway, I've lurked here for a while and have decided to sign up to hopefully get some specific help to some of the questions I have.  This is a great site!
