Topic tags/keywords: dust collection harbor freight

When I first plugged in my Rockler wall mounted dust collector (650cfm on a good day) to my Laguna combination planer / jointer it looked like it was snowing wood shavings. Clearly I was nowhere near sufficient flow for my combo machine.

So I took the plunge, used that awesome coupon in the March Wood Magazine (yes Borders has it on the shelves) and bought the Harbor Freight 2HP, 1500cfm dust collector. The 0.5 micron filter was ordered as well, although it hasn’t come yet.

Now, assembly of the Harbor Freight dust collector was an experience I wish I had on film. I don’t think there was a part I didn’t assemble, realize it was on backwards, and have to take it apart and start again. Had to drill out some ill fitting holes, and go to Lowes to pick up metric hex bolts and lock nuts. Eventually, all went together and it seems to be working well. Also, pretty quiet, and works great with the Woodcraft remote controls.

Interestingly, I only had 58 extra bolts, nuts and washers after assembly. I have no idea what those were for, but they were a smaller size than anything on the machine. Wierd.

The planer / jointer still is dropping shavings. I might have to upgrade to 6” flexible pipe instead of 4”, but it’s still a tremendous improvement over the Rockler wall mounted unit.

Now I need to figure out what to do with that.

What did you do with the rockler wall mount unit?

In the future … once you’ve said that (above), you don’t have to tell us it was Harbor Freight.

We’ll know ;-)

Kind of a fan, myself…..

You can google a bit and find other mods other ww’s have made. One (here) recently built a ‘stand’ for his motor that gave it a short, straight shot from filter to motor … increasing his flow. Others make a “stovepipe” modification that, allegedly, cleans up the fun from filter to motor without relocating the motor.

I haven’t done any of that, but did add a chip separator…

Quite a functional combo. Enjoy yours!!

I still have the Rockler wall-mounted unit. Interested?

I have a trash can chip separator on mine also. Works amazingly well.

I use the HF 2hp unit as well with no complaints. I think it certainly is the best value out there. 4” PVC runs through the back wall of the shop and into a Thein Separator then onto the unit which exhausts onto the ground. I can hear if the unit is running through the wall but 90% of the noise stays outside in a sound insulated 3’X4’shed.

Im thinking of buying, what I think is the same unit, on E-bay. The price is around $245 shipped. With the Bing rebate it will be around $225 total. I dont think thats a bad deal for a 1500 CFM 2HP setup and shipping included. Plus no sales tax.

The price with the WOOD magazine coupon was $139.99.

Still valid until sometime in May, IIRC.

I too bought that dust collector from Harbor Freight with the Wood Magazine coupon. Was the first item I bought from HF. I must say, I am impressed with this machine for the short time that I have had it. I would not have bought it if not for the input from the people on this site. BTW, I had to go to Tractor Supply to get the hardware that was omitted in China.

Wood shavings from jointer not collected by dust collectorNow working on removing the Y piece from the intake. That increases the intake to 5”. Still not the 6” I think I’ll need.

My Laguna Jointer / Planer combo truly needs big airflow to remove the wood shavings from jointing. The above photo is the shavings from face jointing and edge jointing one 2×6. Reducing the ducts to 4”, going through the built-in Y fitting, through the 30 gal trash can separator, then one other Y doesn’t produce enough airflow (trying to connect all my equipment).

I’ve got some 6” flex pipe on order. When that arrives, I’ll see if that produces enough airflow directly from the trash can chip separator.

Has anyone removed the large metal ring and retrofitted it to have a 6” intake instead of 5”?

Been working hot and heavy to improve the dust collection in my shop.

I have purchased the HF 2HP collector and have the Wynn Filter on top.

I have replaced the input Y connector with a 5” – 4” adapter, and have 5’ of flexible 4” hose to a 30gal trash can with the Rockler 4” trash can cyclone adapter on it.

The other side of the trash can has 4’ of flexible 4” hose to a Laguna 12” Planer / Jointer SCM combo machine.

When I face joint a 6” board, a pile of wood shavings drops down to the planer table, and remains around the blades. This hasn’t changed despite reducing the number of fittings and removing the Y intake and replacing it with a 5” – 4” adapter.

Any suggestions as how to proceed next. Clearly the flow isn’t sufficient, or something is wrong with the dust collection on the Laguna.

I was thinking that I would next take the garbage can collector out of the system (though I really like the concept). If that doesn’t work, then I think I would have to custom make a 6” intake port for the HF collector and use 6” hose straight to the Laguna.

Are there any other approaches that I should be trying?

I’d try without the trash can first, as that’s easy. Next, I’d try a 5” hose.

I have the Y adapter on mine, and notice that with one side blocked, the flow is greatly reduced. By running only one 4” hose, you’re probably getting the same effect. Going to a 5” hose may get you 50% more flow.

Don’t have 5” hose handy. I might enlarge 5” to 6” and run 6” to the jointer/planer, then reduce it back to the 4” inlet for the jointer/planer.

I’m also thinking the trash can may severely reduce flow. Not really in the mood to make a 6” Thein Separator trash can lid, but that may be the way I need to go.

OK. I installed a 5” to 6” adapter on the inlet, ran 8 feet of 6” flexible tubing to the jointer/planer, then reduced that down to 4” for the jointer/planer. The chip collector garbage can has been removed.

Chips are less, but are still accumulating on the planer bed when jointing. I’m thinking this is a design deficiency on the Laguna.

Here’s the planer bed with the new setup:Whood shavings on planer bed when jointing

It also throws a small quantity of shavings on the top of the jointer bed:

I’m going to try to replace the HF inlet with a 6” inlet (what a pain to find the fittings. My local Lowes didn’t have any 6” PVC flanges.)

Are there any other options? Is the true airflow out of the HF 2HP dust collector really below 1000 cfm (the minimum the Laguna specs says it requires)?

I’ve thought of putting in a T adapter with a 2.5” hose to sit on the planer bed as a second dust collection inlet. Crazy to have to do that, but I’m leaning in that direction.

Anytime you reduce to 4”, you defeat the purpose of the larger hose. So running 6” hose is the same as a 4” hose, if it’s connected to a 4” port.

I’ve got a 6” Jet jointer, and my old 1HP craftsman dust collector get’s all the chips from it. And the HF sucks at least twice as hard as the Craftsman. So yeah, I’d say it’s probably an issue with the jointer design. Being open on the bottom, will always allow chips to escape.

Hoping that’s not true, but I’m leaning in your direction. In the process of increasing the intake to 6”. At least running 6” hose to the Laguna will decrease the loss in the run compared to a 4” run, though the 4” connector at the end will clearly take its toll also.

I just opened the HF, and noticed the the impeller is only 10”. Has anyone retrofitted another impeller and housing onto the motor from the HF? Seems easy enough to do. I was thinking a 12.75” impeller from a Grizzly 1028Z2 should still be easy to drive from the 2HP motor. Are the shafts the same size? That would make it a true 6” intake, 5” output DC, and should raise the CFM above the spec’d 1550.

Tim Taylor around anywhere??? Jet engine perhaps?

Of course, the price of the new impeller and housing would make this run more than if I had bought the Grizzly in the first place. Wish I had kept the boxes from the Harbor Freight unit.
