Make a Dewalt 733 planer dust hood for less then 5 bucks

This is my first blog so I hope I get it right. I bought a used 733 a few months ago that did not come with a dust collection hood. After getting it home I had to try it out, ran a pine board through it and blew chips and dust 5 foot . Well being frugal as I am, no make that cheap I decided to try and make something to get me by until I could find a factory hood.

This is what I came up with, I have been using it for a few months now and am happy with it so thought maybe some of you could benefit from it.

The first thing you need is a 17 inch piece of thin wall schedule 20 sewer pipe.
Lay the pipe on a flat table and place a framing square against it to mark a strait line the full length of it like this. I used a black ink marking pen so I could see the line better

Now you should have a line like this.

Now measure 3/4 inches from that line makes no difference which side of the line you measure from. Now use your framing square again and mark the 2ed line like this

Now your pipe should look like this with 2 lines 3/4 inch apart.

Next step is to measure with the pipe facing you, mark a line on the right side 3 inches from the end connecting the 2 lines, it should look like this.

Next measure from the left side of the pipe 5/8 inch from the end and connect the 2 lines, it should look like this.

Ok now we get to the good part. Take a jig saw or other tool and cut out the space between the 3 inch right side and the 5/8 inch left side I found that a jig saw with a fine tooth blade worked good after drilling a large starter hole at each end. Try to stay on the line to make it strait, I also found that cutting right to left on both lines a little at a time and cutting off the waste as I went kept the cut of tab from getting to long and jumping around help.
It also helps to have someone help hold the pipe as you cut, I placed mine in a vice to hold it but it also required another person to help me worked better. When you get it cut it should look like this.

The next step is to cut a center line on the 5/8 inch left side, Mark a line down center of the 3/4 inch space on the 5/8 side and cut the pipe apart when done it should look like this.

Stay with me were almost there.

The next part you will need is a plug for the end of the pipe that will go on the left 5/8 inch side. I cut a 4 inch plywood circle and attached a small square knob that I screwed on it from the inside, 4 inch is to small and 4 ½ inch is to big so I just made it 4 inch and wrapped a few layers of duck tape around it until it felt good for the final fit, don’t wrap the tape until you are ready to install the plug and the pipe is attached to the planer. When you are done it should look like this.

Ok now we get to the place where we mount the pipe on the planer. when you look at the back of the planer you see the chip extractor area, Its about 1 inch tall and about 11- 12 inches wide, it will look like this.

Looking at it from the side you will see that there is a small tab at the top and bottom and this is where the pipe is going to slide onto. I looks like this.

Now we are going to put the pipe on the little tabs, start on the right side and slowly slide the pipe over the tabs. do not try and lift it on them as your pipe may split on the right hand side, ( don’t ask me how I know this LOL ) just slide it until you get it so it fits from one side to the other. at this point you may have to make a few corrective cuts to get yours to fit just right. The next 3 photo’s show sliding the pipe on over the tabs.

When you get it just right the left side 5/8 inches will fit like you see in this next photo, the reason for the 5/8 inches is so you can put on and take off the 4 inch end cap and be able to clear the side of the planer, leave this side at 5/8 inches and make all your adjustment cuts from the right side to make the slot fit the tabs, when you think you have the right length of the slot you may need to enlarge the 3/4 inch slot to relieve pressure on the pipe on the right side as it will fit real tight. The left side should look like this when installed.

Now all there is to do is put the 4 inch plug in and screw it place, I just slide it in place and drilled two small hole so it would be easy to put the screws in, when done it should look like this.

When You get the screw holes drilled, then ad some sort of hanger to hold the pipe up and to keep it firmly in place. I used some of this plastic pipe hanger material which worked out great, it looks like this.

And when it is in place it looks like this.

Well that’s about all there is to it, I stuck a 4 inch metal elbow on the end and it is ready to hook up to the dust collector. This is what it looks like all done.

Like I said at the start of this blog the collector has worked for me for a few months now. I don’t think I will spend any money on a factory hood, I have read where the factory ones clog up some, one this one I have never had it clog up with chips and my dust collector is about 10 feet away and only 1 hp. I do get some blow back of small shavings, but I also get them with the factory hood on my Delta planer, so I don’t think you can get them all. Like I said it works for my.
If you have any questions let me know and I will try to help out.

Happy planning
Mickt

Just found LumberJocks, signed up, looked in the Blogs, and lo… the very thing I needed to find; posted only minutes before.
I also have a 733 second-hand with no dust-collector, and found I can’t order one as they’re obsolete.
I’ll give this a try, thanks!

from what i see in the pictures it looks like the strap will get loose if you raise the head to plane something thicker, you may have to remount it maybe, but nice job fitting the pipe to the machine, have you tried it without the plug, with it out it might allow more air flow to carry the shavings,

Yes cutmantom, good point.
I saw that, but figured I’d see if there was some place to attach the strap to the head instead of the frame.

Great instructional! I love the low cost solutions. Like you said, it may even be superior in function to the manufactured piece.

PVC… duct tape… Had you worked in a cinder block it would have immortalized this project!

Thanks everyone for the commits.
I forgot to say in the blog that I believe a 5 inch pipe may work as well for those that use 5 inch dust piping.

Welcome to Lumber Jocks, you will find more information here then you thought possible and a great bunch of guys and gals ready to help you anytime.
Hope it works as well for you as it has me, like cymantom noticed the strap needs some more work but it should not be an issue. I had been meaning to put one on for a long time when doing this blog I was just in a hurry and did not think it out.

Cutmantom
You are right about the strap, I didn’t about it at the time I put it on, just found a convenient screw to attach it to.
There are two other screws on the planer head that can be used these are the two that hold the blade cover down. The reason I did not use these is that the strapping did not line up very well. I think I might just drill two small holes in the pipe inline with these and hold the strap down with some small nuts and bolts.
I had been thinking of a strap type hold system for some time as the pipe with out one will hang down a little because of its weight and the planed board will move it up just a tad when it comes out of the planer.
Yes I tried to run it with out the plug in and all it did was to blow the shavings out that end making a mess. I did think about drilling a bunch of small holes in the end for more air but I found that the way it is it works ok, not saying that it may work better with more air. I also thought of placing screen wire on the end?
I bet use all working on it together we will figure it out, if anyone comes up with a better idea post it.

Thanks again
Mickeyt

I have been using a 733 for about 10 years with out dust collection. When I clean up my shop this is the biggest place to clean. I will have to give this a try. Thanks from all of us too ‘busy’ to think.

-- Robert, so much inspiration here, and so little time!

Looks like a great permanent solution. Where were you a year ago? I bought the planer hood and adapter (with tax and shipping $60). I used a 14” floor sweep from my shop vac with duct tape until the hood came in. Nice work.

Welcome to Lumber Jocks, great place with lots of great folks ready to help you anytime.

I am making an inprovement to the strap that holds the pipe up, I don’t know why I did not do this the first time around, in a hurry I guess, anyway here is the fix.

Use the screw on the left side that holds the cover for the blades. You can see a photo of it in the photo.

Next photo shows it in place

Next photo shows that the planer head will go up and down now like it should.

In this last photo I try to show that there is clearance under the the pipe and the planer bed for boards the go through with out hitting the pipe.

Thanks everyone for the feed back on this, makes me feel good that it might be usefull to some and i’m able to pay back from all the information I have gotten off Lumber Jocks. I don’t post very much but I do lurk most every day.

Thanks again
Mickeyt

Mickey,

My DeWalt 733 planner has a 2” wide opening.

I guess mine is missing that lower part. Sucks.
