Been lurking here for a few weeks, and this site has a lot of great info, so time to join.
I just had 14 windows and 2 doors replaced in our house, and I’ll do the window jambs and trim in a country style of trim with red oak.
Windows were opened to the rough opening, so all original trim has been removed, and will be replaced with new.
I’ve done a few wood working projects over the years, but never got a DC. But I need one now.
DC will run Delta 10” table saw, 12” miter saw, 12.5” planer, and maybe hook it to my 6” joiner—most likely portable at first by changing the hose, maybe wall mount with hard pipe later.
I’ve got a detached 3 stall garage with about 30×20 of it shop area. I do not want dust covering everything, and soon will be cold in the midwest, so the propane heater will hold the temp, but I can’t open a door to get rid of airborne dust.
I know DC is a common subject, so hope I’m not beating a dead horse.
Harbor Freight is a bargain. But the more I read about it, the impeller is too small, and poor design. The Rikon impeller seems like a great design, but a few posts say putting it on a HF causes the current to go 20 amp or more. Sounds like several people have it working great, but some get too high a load on the circuit, so don’t think I want to risk buying all of that, and having the electric issue (and this assumes Rikon still sells the impeller w/o requiring a serial number and has them in stock).
To control dust as well as possible, I’ll most likely mod the DC with the Oneida Super Dust Deputy cyclone, and a pleated paper filter (Wynn or BHA ProTura). But will most likely use the DC stock for a bit to see how well it works (then for DC while I cut wood for the DC mods).
I’m leaning towards a Grizzly G1029Z2 2hp, 240V. The garage/shop is 6 years old, and I can add a 240V pretty easy. At the stated 1550 cfm, it should easily get the chips and a fair amount of dust too. The downside—$444 to my door vs ~ $170 for the HF.
Sorry for the long-winded first post, but comments, recommendations, alternatives are welcome.

I always say get the biggest you can afford so long as you know you will use it.
The HF is $170 but figure the price after you do any upgrades, such as the impeller and making a new stand to rearrange everything. When you add your time into it, you’re really not that much cheaper than going with a true 2hp unit
At that size though, you will get the best air flow with 6” duct and hoses so you would have to modify the tools.
Even the miter saw and small planer can be modified if you’re handy with metal.
I’ll be posting photos soon of my miter station with a hood for dust control. The collection on it is excellent but, it does take a little time making a stand and getting everything set up.

Well, that Griz only has 2.5 micron bags, and you will still be putting some of the finest particles back into the shop air. Look for one that has at least a 1 micron filter/bag/whatever to capture those particles. You must have caught this somewhere in your perusing: the CFM ratings are usually about as accurate as the 6.5 HP you shop vac has. Don’t get wrapped up in the CFM, you’ve picked a very good starting point (2 HP, 12 3/4” impeller)...but at least for me those bags wouldn’t do the job.

Good comments for you already mentioned.

I would get a collector with a good canister filter to control fine dust.

Wood Magazine tested the Grizzly dust collector and gets 700-800 cfm max. This should be enough for your tools.

Welcome to Ljs
Depending on your budget as to what’s best for you the best value is the Harbor Freight 2hp DC unit .I’ve never felt the need to upgrade mine because of the low cost I have several units. I also run mine outside to eliminate the need for an upgrading the filtration. For $180 (after 20% discount) they are hard to beat.

I know it’s way out of the budget you’re describing but if you really want to keep[ the dust in your shop down then I would recommend getting an Oneida unit.{883C6AA7-4C85-49FD-9EEA-C51D09DC8B19}

D38 – I’d also suggest making some sort of air filter to circulate the air in the shop and run it through a filter. That will go a long way to keep the fine airborne dust down that the DC doesn’t get, and there is a surprising amount of dust that isn’t picked up by the DC. There should be a number of projects on LJ where folks have built their own rather than buying one.

Thanks everyone for the great replies.
Yea, the HF is so low priced, it keeps drawing us to it. As long as it fits the buyer’s needs/price point, its better than no DC, so its nice to have them on the market. But the Rikon impeller swap has me concerned with amperage draw.
AZWoody – good input on best we can afford. I usually buy at the extremes – low end for a one and done tool, or go big and cry once for longer use tools. I’ll also keep an eye out for your miter saw collector—I have noting now and generally drag it outside.
Even with the Grizzley, I’ll most likely add the Oneida Super Dust Deputy and a cartridge filter to improve the finer dust control. And maybe a 20” box fan with a good filter for starters, and either a homemade or purchased whole room filter if I feel I need one.
I’ll most likely also buy a HVLP for spraying topcoat (possibly Fuji Semi-Pro, but that will be another thread), so plenty of money will be flying out of my pocket. $$ saved on one item allows for more spent elsewhere.
But doing 14 window jambs/trim myself will still most likely put me $$$ ahead after a souped up DC and HVLP (my time being free of course!)
So I’m leaning towards the Grizzly 2HP.
Thanks again

The more internet surfing I do, the more I like the Grizzly 2HP G1029Z2P. Don’t know why they use an aluminum impeller. Maybe easier to get spinning on startup.
I was in Omaha/Council Bluffs Friday, and went to the Harbor Freight. Picked up a couple 300 lb mobile bases that should be useful in the shop.
Also got the HF DC starter kit (2 4” 10’ hoses, 2 blast gates, clamps, and 3 ports) with the 20% off coupon, so $51. Goal is to use it to get started, and collect chips while making a miter saw hood, etc. Then I’ll add the Oneida Super Dust Deputy and a cartridge filter before starting on the oak for the window jambs/trim. I’ll have to decide on a revised shop layout, then hose type and routing (and hose size—I’d like 6” to the tools).
First up will be adding a 220v outlet to run the DC.

Depending on where you are located, I have a harbor freight dust collector in a mobile cabinet (noise control) with a wynn cartridge filter that I’d be willing to let go.

I’m in SD, so a bit much for a road trip.
But thanks for the info, and good luck finding a good home for it.

In your size shop and your dust goals, you should at a minimum go with the Grizzly. Even if you get the HF and put in the a 12” impeller (that should have already been there). You are squeezing into a housing that was designed for a smaller 10” impeller. The grizzly 2HP is better in two ways that will be important to you, First the impeller is 12.75” in diameter which will give you more static pressure in your system (the larger the diameter the more SP the blower can provide). Second, the grizzly impeller is taller (I believe by almost an inch) so with the extra diameter and height you will get more CFM from that blower. Don’t compare what the specs say. They both spin at the same speed so the impeller size and blower housing determine your performance.

The SDD is a great addition to your system. It has a 5” intake which is the diameter you should maintain for your ducting. Some try to use 6” because they can get it in PVC, but you need more velocity in 6” pipe than your system will be able to maintain (to avoid clogs). The other mistake people make is immediately downsizing to 4” (because it is really cheap) and killing performance (which you need). So 5” hvac ducts will work the best.

Hope that helps. Let us know what you do.

Carl, great info – impeller diameter is published by most companies, but only in-person inspection or someone posting on a forum like this allows us to find out about fin height vs housing. Makes sense they need to be optimized to each other.

The decision: Grizzly 2hp. Delivered to my employer’s freight dock today. Truck got there after shipping/receiving left for the day, so the driver left it without a signature from anyone. I know they need to keep moving, but he had my cell phone # on the shipping document. Some torn cardboard, but no product damage. Had a coworker set it into my pickup.

I’ll set it up this weekend. And add a 220 volt plug in. I’ll use it in stock configuration to make table saw and miter saw dust collection enclosures and then a stand for modding it into a 2-stage and MERV filter. Then on to the real project—14 window jambs/trim.

Thanks for everyone’s inputs. Lots of good equipment out there. It all works for someone. Knowledge offered here allows us to decide the best match for each of us.

I have a Grizzly 2hp dust collector that I bought about 20 years ago. It is still going strong and I long ago replaced the top bag with a pleated filter. I use a 30 gal trash can with a “cyclone” lid at the planer to catch shavings, but all the other tools go directly to the DC bag. I use a 6 inch metal duct trunk line with 4 or 5 inch drops to tools. Usually have one or two blast gates open at a time. System works pretty well. I also use a JDS HEPA filter hung from the ceiling for airborne dust.

Do yourself a favor and don’t skimp on dust collection. I used to have a cheap dust collector and thought it was working well enough, big mistake. I upgraded to one of these
along with one of these
I HUGH improvement over what I had
