I guess I haven’t spent enough money yet. As I suspected, I’m pretty sure I need to upgrade my dust collector to keep up with my 20” planer I just got.

I got to use it for the first time this morning smoothing out some 18”x55” panels I glued up for a chest/changing table I’m building. I had 3 of them and made a couple of light passes on each side. When I got to the last side of the last one I had to empty the dust collector, which admittedly was about half full when I started. It is a 2hp Grizzly with a bag. It did a really good job until it filled up. The planer is a spiral head and makes lots of little chips. Most of them fell into the plastic bag but quite a few were caught in the filter bag.

I looked at the trash can style chip collectors on Woodcraft’s website but don’t have a clue how well those work. Do the trash can things work as advertised or does it diminish the suction? I’m thinking I could get a filter canister for the Grizzly and the trash can collector for a lot less than a new 2 stage, if it will work. Any advice would be appreciated.

Do a search on here for Thein chip separators. It is a cheap DIY solution which works extremely well. It might be just what you need. I built one and I am continually impressed by how well it works and how cheap it was to build.

I have the Woodcraft cycone lid on a 30 gallon metal trashcan and use it as 1st stage separator in front of my 2HP HF dust collector. I have used this setup hooked up to Dewalt 735 13” planer with excellent results.

I almost filled up the 30 gal. trash can cleaning up the shop last weekend and so far have absolutely nothing in the collector bag on the dust collector. I am very happy with the performance. The only thing I have not tried it with is very fine sanding dust but, see no reason that would be an issue. Will be doing some sanding this weekend and will post results.

Think regular price for trashcan lid cyclone is about $30 but goes on sale for closer to $20. Woodcraft also has one for a 5 gallon bucket but I have no experience with that one.

I also have the Oneida Dust Deputy cyclone separator in front of my big shop vac and it works very well also. Nothing in the shop vac so far and have emptied the Dudt Deputy several times.

Good Luck!

I have a Thien separator on a 55 gallon plastic drum (open head drum), and it works great. Cheap to build too once you get the drum… My project post is HERE. The only commercially available trash can lid separators I would consider are the older Jet, and the current Veritas ones. They do the same thing the Thien lid design does, takes in air from the outside edge of the container, puts it out in the middle. The others take in and put out on the outside edge, making a pretty straight shot for dust and chips to get through, kind of like driving your car up, and down on ramps to the freeway…

Jim, I have a cyclone separator as well and it works well. I will empty it 5 or 6 times before the bag on my PM1300 needs to be emptied. It is much more convenient to empty since all I do is take the lid off and dump the trash can onto the landscape to use the shavings as mulch. The only gripe I have about the separator is that there is an elbow that attaches to the underside of the lid. It is just a friction fit and will occasionally come loose. I will probably glue it in one day when I get aggravated enough.
