I did a fairly standard HFDC modification a couple of years ago that just got finished today. Although I’ve never posted it as a project, I have posted photos as a reference in a couple of DC threads.

Today I got a PM from ChunkyC asking the very logical question “How do you support the weight of the motor/blower unit when you empty the can?” Anyone who has modified one of these will know about the weight and the “top heavy, wants to flip over in your hands and cut you” tendencies of this assembly so he didn’t want to have to lift it off every time he wanted to empty the can.

Well, I told him how I had done it, but that was just a little bit of a white lie. It was, of course, what I had always planned to do but I hadn’t actually done it. I’ve been lifting it off and cursing when it flipped over and cut me.
Anyway to get to the point I decided to make an honest man of myself and now between the actual performance of the task and this public apology ;-) to ChunkyC, I believe that I will be able to sleep tonight.

Isn’t it nice we all have fellow LJ’s to kick us in the butt every once in a while to get us to finish what we have started? I think so….....................Thanks ChunkyC.

This is my “Sky Hook”. It goes to a hook in the rafters.

Good work Paul. It looks a little like a robot serving a pitcher of beer?

shipwright,

I don’t want to ASSUME (you know what happens) that you made a Thein Baffle, so I must ask; Did you make a Thein Baffle & can I see it?
I just upgraded to the Wynn 35A274NANO cartridge filter and a Long Ranger III remote. I need to do the Thein Baffle modification next. As soon as I complete the building of an Air Cleaner from a repurposed, variable speed, squirrle cage, furnace blower I’m going to construct the a “Top Hat” Thein Baffle Separator and also run 4” metal ducting throughout the shop.

Pretty please, with a cherry on top, can I see some pictures!!!

Is it a hand operated chain pully or do you have a comealong attatched? On a track or just hung as needed?

I don’t really know what exactly makes a separator a “Thein” except that apparently one Phil Thein is among the many people who have devised cyclone style dust separators. That said Yes, I did make a cyclone style separator for my HFDC. It is likely unknowingly plagiarizing several I have seen before and has some of me in it too. Let’s just call it a cheap cyclone. If you follow any of my stuff here you’ll know that I like to keep it simple and cheap but not sacrificing efficiency.

Mine is made from a few cheap and easily accessible parts:
1) Metal garbage can..... stronger than plastic and it has a rim around the bottom that makes it stay put on a circular plywood support base.
2) MDF top because that’s what I had at the time.
3) Plastic 5 Gallon can.......... Makes a large volume (lower velocity) exit stream to the blower assembly, sticks down nice and deeply into the can, comes with a nice flange to screw to the MDF top, and is cheap and available.
4) Foam pipe insulation to seal the MDF lid to the can.
5) A 3/4” plywood disc mounted on the motor mounting base of the HF cart that fits inside the garbage can bottom rim
6)A 90 degree plastic DC elbow to direct the air in a cyclone style flow around the can.

I used the original HF cart but had to move the bag mounts an inch or two away to make room for the can.
Probably the only difference between mine and most others is that I thought a large bore exit flow seemed to make sense to me. I could be wrong but it works a treat and all I get in the lower bag is very fine dust.

Hope this helps

Paul

DocSavage45, it’s just a chain on a hook. You lift the head a few inches and hook it on the chain.

Thanks for the pictures & detailed description.

Again, I don’t want to assume. How large is the hole in the bottom of the 5gal bucket?

I guess that is as big of a hole as you could get in the bucket!

Thanks for the info.

Thanks for the info Paul.

I have a separator on my todo list but have not gotten to it yet.

The question I have not been able to find an answer to is do we still need a tall plastic bag under the filter or can we make shorter?

There’s no reason, that I see, not to make it shorter.

The only reason to keep the stock bag is so that it can rest on the cart instead of hanging in the air I guess. It would take a very long time to fill it.
