I bought a drum sander to sand 4000’ of cedar siding yesterday, and will need some form of dust collection. Pretty fine dust in large volume.

It would be nice to have something i can continue to use later in the shop, though it is not as if I have a lot of wood working projects, though the planer makes quite a mess without DC! Ideally I would be able to mount it 5’ off the ground in an area where I have a high-bay in the garage.

Current craigslist options are:
Delta 1.5 HP (quite a drive), 1200 CFM? – $225
Woodtek 1.5 HP (700 CFM?) – $175 (fan mounted vertically with 2 ports)
A different Woodtek ?HP – $180 (fan mounted horizontally)

-or-

New Harbor Freight 2 HP – $175

-or-

Try to make a Rigid shop vac work ?

What would you do and which ones work best?

Edit to add: There is also a Rikon portable 1 HP collector for $100. Horizontal bag.

No matter what you buy, I totally recommend you front end any decision with a Dust Deputy... Will help any cheap sucker, suck with the best (that don’t DD).

A drum sander is really tough on a dust collector because of the fine dust. You need a cyclone or will clog filters fast.

I think you need a 3 hp Dust collector for that job.

Thanks, guys. Don’t think I’ll be buying a 3hp for just this one project; I need to see if I can get by with something less powerful.

I do see a dust deputy locally on craigslist – the size for a shop vac. Is there a chance I could get by with a dust deputy and a shop vac? that guy also has a cyclone, though i don’t imagine you use two together.

forget the shop vac it will not do what you need,their for suction you need volume of air on a sander like that.if your tight on budget you could try the HF but in my opinion a cheap dust collector that needs a lot of upgrades to be a real dc.

Can’t disagree with that… Once you start working to a limited (as opposed to a limiting) budget, it’s just gonna cost more and more for upgrades and workarounds.

Either way, for practicality, I will not suggest the cheapest… when it comes to shop-vacs (colloquially) a dust deputy is your best friend and for a non-cyclone dust extractor, a super dust deputy should be considered.

The chances of a “single use” is nearly as far fetched as marrying only once… does happen, but don’t expect it.

I hear you all, but this is a very large remodel project, and all the thousands of dollars have added up to tens of thousands of dollars over budget – so I have to be careful. Prepping 4500 lf of siding is a tiny piece of the whole multi-year effort.

I do have an 800cfm unit for scrubbing air, but I’ll be outside, where I just need a respirator.

Many thanks for your guidance and thoughts.

Which drum sander do you have. Does the user manual have any guide line for dust collection?

I have a 15 inch wide belt sander. I have a 1200 cfm dust collector with a pleated filter that sits on top. I recently ran a bunch of old used 2×6 cedar decking from when I replaced my deck. The dust collector has 25 foot 6 in flexible duct/hose connected straight to the sander. While it was enough I’m glad my collector wasn’t any smaller. When I was done there was good coating of dust inside the sander and I had to rap on the filter now and then to know the fine dust off. I only ran a couple hundred lineal feet or so.

No way of a shop vac.

I think you will have ptoblems. Cedar is sticky and the dust adheres to everything. If you do not have a strong enough dust collector, you will clog the sand paper.

This is a very difficult job.

I think more depends on the sander than the collector. I agree on filters clogging. . Exhausting outside with or without a cyclone is your best option.

I am using a 1.5HP Jet blower on a Super DD, exhausted outside. On a Supermax sander there is zero dust, that said with the dust control built into the sander I am confident even a 1HP collector would do the job.

My suggestion is a single drum a sander b/c a dual drum is harder to collect. if you don’t have a big need for a collector, a 1 HP wall mount shoukdl do the job and can be repurposed later for miter saw collecting or even a garage vac.

I had a 5 hp cyclone for my 38’’ Woodmaster drum sander and it worked good. Years ago I had a 16/32 and tryed a shop vac and it did not work. Like stated do it right or pay more in the long run.

Thanks guys. I get the challenges, just not going to go spend $500 or $1000 on dust collection. What this does tell me is that I will be much better off looking at the used 2HP models instead of the smaller ones, and good to hear your experiences with a Supermax, Robert. That is valuable to know.

Will the trash can lid-style dust separators add much benefit for this type of dust? I see one locally for $10.

Also, will I have more or less issues with 80 vs 120 grit for either dust removal or dust going through a standard dust collector (I think most I would by off CL would have a 5 micron bag)? This wood is going on a soffit, so you aren’t seeing it up close, and it doesn’t need to be finely finished.

Working outside with the drum sander? Get the $100 rikon. Hook it up with as short a hose as practical. Remove the bag and point it away from where your working. Wear a respirator.

It will pull the dust off the drum and blow it generally away from you. Your neighbors already hate you for doing a multiyear renovation.

It will still be worth $100 when your job is done.

I have a 16-32 Jet drum sander and a planer and I use a Harbor Freight 2 HP with a home made trash can cyclone lid on a 55 gallon cardboard drum and it works very well. I copied this Woodriver cover using plywood and a 4” PVC elbow. Like you I got involved with a large job about eight years ago and had to make something quickly. The local store did not have a cyclone lid in stock at the time. I am still using that set-up, but it is not perfect, but good enough inside my warehouse. I have a friend that uses the cyclone lid and the 2 HP Harbor Freight in his business and it also works very well. Here is a link to the cyclone lid at Woodcraft for $33.

If your dust collection is not sufficient, dust will pack into the sandpaper and the board and you will instantly have a burnt line on the surface of your board. Usually the sandpaper cleaning stick will NOT clean it all off, but I highly suggest getting a couple of them and clean your drum often. I could not find this on the Woodcraft website.

It is going to take you a while to learn about your machine. Make a sample including the finish and I think you will be able to save yourself some time.
