I built a particle separator that used a thien baffle in 5 gallon buckets. It has a small footprint, all one vertical unit, rolls around, has onboard hose storage and works great. Watch video.
My shop vac has been there for me for years and have had no problems with it. Been reading about importance of dust collection and since I never even cleaned the filter once in 8 yrs thought I would give him a break and my lungs too. The wife came in the WoodShop/laundry room and caught me in a snow globe type situation and insisted (I use that term loosely) that I do something. Besides, her clothes had a nice layer of sawdust on them. I don’t recommend that. Decided to head to HD an...
Lets take a minute to review our original design goals: The shop vac should turn on when a tool turns on – this is a simple one but its the base functionality to which we build off of. Provide the ability to run small loads off the system without turning on the DC. Provide the ability to connect multiple tools to the system, all which can independently turn on the DC. Provide the ability to keep the DC on for a variable amount of time after the tool turns off. Provide the ability...
In the last post, I described the inputs and outputs to the system but left the main guts for this post. First, lets define a couple features which we should try to build into the black box: The shop vac should turn on when a tool turns on – this is a simple one but its the base functionality to which we build off of. Provide the ability to run small loads off the system without turning on the DC. Provide the ability to connect multiple tools to the system, all which can indepe...
Back in November of 2014 I posted a project showing the system I had made to control my shop-vac for automated dust collection. You can see the project here: After posting, there were several people asking me for the schematics so they can build their own. So instead of only posting the schematics I drew up, I though it would be a good idea to provide a little additional explanation for everyone else that might not have as much experience with electronics. I don’t believe its ...
Finally got my version of thien separator working after several rounds of trial and error. Thought I could share my findings. It’s made of a 5 gal big-box bucket, plywood, and plastic plumbing fittings. A 32 gal plastic trash can was used for collecting dust. Silicone adhesive and insulating self-adhesive tape were used to make the separator and dust bin combo as air-leak-free as possible. This is inside the separator looking at the intake pipe (black) and the pipe (whit...
I have noticed any number of shop vacuums are being manufactured under a variety of brand names with a large On/Off rocker switch on top. The switch is failure prone. Saw dust and fine wood chips can accumulate on top of the vac and work their way into the switch. That was certainly true of the Performax vacuum. Performax 4 Gallon 5 Peak HP Job Site Wet/Dry Vac Number: 2404827 that I purchased. It lasted a couple of weeks stationed by my lathe. Then, nothing – it would not turn...
In an article published in Fine Woodworking by Thomas Schrunk provides a plan for silencing your shop vac. I drew up modifications of his plan for my Rigid 5hp shop vac and realized that I was creating a behemoth (>36h,30w,36d) when you add on a dust separator. For that size I might as well just save up and buy a legitimate two stage dust collector. I decided to forgo the baffle design for a simple box that will sit on top of my shop vac and ride on the shop vac’s casters. That way ...
I started this project a year or two ago when I read about the benefits of a two-stage system. I purchased a Woodstock lid type separator for a five gallon bucket and when I filled it up too fast I cut a hole in the bottom of the five gallon bucket and put it on top of a Rubbermaid bin. Big mistake. However I was using the shop vac all over the house, most of the time by itself so I never really tested the efficiency of the system until the other day. While it was collecting most of the bi...
Drill Press Station – Table/Lift/Fence/Vise/Drum Sander My drill press is a small inexpensive bench top type, and until I get a good floor type one I am trying to get the best out of it. One of the first things I did was to change its old pole with a stainless steel one. Why stainless steel? Well it was the only piece I could find that matched the diameter and you can slide up and down smoother. So the pole got a lift-up of about a foot taller. One of those ikea wire sh...
