Went to Rockler last week to use my 20% off coupon and while I was there I saw a package of fittings
http://www.rockler.com/product.cfm?page=25225 for building a separator for $19.00. I have seen all of the home built and store bought separators so I figured I’d try making one myself to go along with my dust collector. The drum is a recycled 40 gallon fiber shipping container with lid and V band clamp that I purchased from a shipping company for $11.00, the hose I already had on my dust collector. So for $30.00 I now have a separator. Earlier in the week I’d been cutting some wood on the table saw but hadn’t hooked up the dust collector since I was only gonna make a few cuts (yea right) and when I opened it up to clean it out it was full so I figured now was the time to finish the separator and test it out. I emptied out the collectors bag, hooked up the hoses to the separator and began sucking out all the sawdust. After cleaning out all the sawdust I opened the drum and it looked like all the dust from the saw was in the separator so I inspected the bag from the dust collector and there was less than 1 cup of very fine sawdust in the bag. Next I tested it on small chunks of wood and carving shavings, then inspected the drum and the bag. None of the material made it to the bag. This thing works great. I highly recommend this product from Rockler and the system, especially if your working on a tight budget. The fittings come with a set of plans for building a drum type as well as a mobile cabinet type with drawers for easy emptying of sawdust for a planner or other power tools. The kit comes with all the fittings you need to build the drum separator minus the drum of course. The fittings on top have wide flanges and have threads that mate with the internal fittings which also have wide flanges. No need for sealant or gaskets, once you snug up the fittings there’s no leakage. Thanks for looking.

There is no reason this should not work. It’s just a drop out chamber. The top diagram is wrong, however. The arrows indicate flow coming out of both connections. Can’t be. One is in and the other should be out. The circular flow arrows, to make you think this is a cyclone, are pretty much wishfull thinking too. But, no matter which way things are flowing, it should git-r-done.

Yes the diagram is wrong, It was more intended for the illustration on the upper right. The picture came from the instruction sheet provided by Rockler.

I’ve been using this type of system for years and it works great. Not rocket science, but it works. At one time I had two barrels in series. When the first one filled up, the next one would fill. I was able to get a lot of planing done between emptying the barrels.

By the way, RetiredCoastie: that hose coming off the left side of your chip separator …

Does that run TO your TOOLS, or … to some other element of plumbing/ducting ?

I ask because … you’ve got a LOT of static pressure right there.

If it’s NOT the hose you take to your tools … maybe you can install a straight section of stovepipe in place of the flex hose ??

Neil the hose is used to attach to my table saw when it’s not stowed. In the pic it’s attached to a short run of 3” PVC to collect dust from my bench top tools (disc sander, mortise machine, spindle sander and drill press).
I plan on modifying the PCV run and the flex hose once I get some last minute details ironed out.

Any idea what your effective CFM are and how loud it is?? This looks like a great way for a rookie to get some effective DC up and running, and if this can handle the TS, a jointer planer, or any other single tool I am likely to end up with, I’ll be hitting Rockler up in a heartbeat!

Thanks for showing the way!

Mike I don’t really know what the CFM is but it works very well on 1 tool at a time. My shop isn’t large so I don’t really need any duct work to reach all areas of the shop. The flex duct reaches across the shop if need be. I do have a 5’ duct of 3” PVC that I have hooked up to the bench top tools that I just hook the flex duct up to as needed. It has enough suction to capture all of the dust from all the bench top tools. I do recommend getting the 5 micron filter bag.

I hope this helps.

Sure does help! Weighing the options on a PSI DC right now as they claim to be pretty quiet and give you 1 micron bags standard, but we’ll see how the budget pans out.

Thanks!
