I have been struggling for the past few years with ShopVacs in my workshop as the filters become clogged so quickly that I really could not use them for extended periods of time without continually cleaning the filter. My previous ShopVac’s motor burned out after the filter became clogging while I was planing some boards. After doing some research it looked like some kind of 1st stage filter option would solve the problem so I went ahead and purchased the dust deputy. The DIY dust deputy kit comes only with the plastic cyclone. When you look at the full kit which comes with hoses and the lid it may be more cost effective to purchase that but I was on a budget and thought I could get by with just the cyclone.
I already had a 5 gallon bucket but I had to come up with an option for the lid. The cyclone came with a little manual that described how to connect everything and provides a few examples but I turned to issue 109 of ShopNotes magazine which details how to build a good looking cart and since I already had a Lowes branded ShopVac figured this would be my best solution.
After testing the system I found it to work extremely well with virtually no dust reaching the vacuum. However, after using it for a while I had to make a few changes.
1. The first change I made was to change the inlet to the dust deputy. I noticed that the vacuum was so strong now that the pipe was collapsing on the bend. I replaced this section with PVC piping. I used standard 2” diameter PVC pipe and a heat gun heat to mold it so that all fittings were air tight.
2. The second change I made was to replace the 2” casters I had used with 3” casters. The plan actually calls for 3” casters and these work a lot better.

I used one of the outlets to plug the ShopVac in for normal operation and then I added an i-Socket Autoswitch to the other outlet so that I can use the ShopVac with a power tool and have it switch on automatically when I use the power tool. This is particularly useful for sanding and when using my Festool track saw. Finally I made a cord wrap on the other side to keep the cord tidy when not in use.[/threecol_two][threecol_one_last][/threecol_one_last]
Ron Walters has an excellent video on his youtube channel which shows how you can make you own cylone, but, with so many projects on the go in my workshop already, I did not want to have to build one and just needed something now to help my shopvac along.
