no previous part Part 1 of Another one of those HF Dust Collector builds... series no next part

My trusty Craftsman shop vac has served me well for the past 25 years. It just won’t die; but it’s time to upgrade. I’ve simply taken in far too much hobby sawdust over the last 25 years.

Bought a HF Dust Collector about three weeks ago. The Spousal Unit was pleased (she was curious as to why it took me so long). If I would have only known that…

The box has not been opened yet. I’ve been plowing through the plethora of information available on Lumberjocks on methods to customize it. There’s a lot of great stuff out there that many have graciously chosen to share. I trust my efforts with this blog will be of benefit to someone else.

Nearing completion on the conceptual design. Here’s the goals:

  • efficient at dust collecting to the extent practical (recognizing the limitations of the HF and my pockets)
  • easily removable drum/barrel
  • hassle free hose/tool storage
  • mobile (my workshop doubles as a nocturnal vehicle storage center)
  • small footprint
  • disconnectable from permanently installed duct work (someday)
  • improved filter / filter bag mounting

Based upon the comments from others, it’s obvious that coupling a Thien separator with a high efficiency Wynn filter is the way to go. Now how to package it?

Here’s the concept:

I’m going with a fiber drum. I like the steel ring/banding at the top and will incorporate it into the bottom of the separator. The 20 gallon size will work best for me. That’ll be heavy enough when it is full. I might even use a second drum in place of the clear plastic bag under the Wynn fillter.

Fitted hose and tool storage is on the left.

To reduce vibration related issues from uneven flooring surfaces, it only has three wheels (back two are unidirectional/locking, the one under the bag will swivel).

It took me a while to come up with a simple, but effective lift for the drum:

A threaded rod/threaded insert will be used to drive the sled that raises the drum. Most likely will add a small wheel (or something compatible with a cordless drill) for rotation.

Several design issues remain. I still need to incorporate power cord storage. Perhaps a built in floor sweep (in the base, ducted/gated?) and a better method to attach the plastic bag. I’m also considering boxing in the fan portion for noise abatement purposes.

I’ve been having a blast with this. Designing something with a purpose and function in mind is the most enjoyable aspect of woodworking for me.

Have I missed something? All thoughts and recommendations are greatly appreciated.

Looks like a good design, The bag under the filter is sufficient, mine has not collected more than a dust pan full in almost three years and I have emptied the drum countless times.

Looks to me that you have a great design!
I have to echo what Tim said, regarding the bag. There is no reason for a second barrel. Actually, you are better off with a clear bag. IF/WHEN chips start getting into the bag, it is your cue to empty the barrel!!!

BTW: I really like the barrel elevation mechanism. Wish I had thought of that.

I’m looking forward to watching your progress on this build….
