Project Information

I know there are a 'few' radial arm dust collection solutions out here, but thought I would throw mine in mix. This is a copy of some others that have been posted with a few changes.

I added some threaded inserts into the table so it could be securely fastened to the table, but also allow for easy removal and replacement.

I added a PVC fitting to the rear of the dust hood to suck up some of the dust that is circulating within the blade guard. The jury is out on how effective this is and how much vacuum I am losing from the primary dust collection hood, but will probably block it off as a test to understand how beneficial it really is.

I think the next time I replace the top surface of the hood, I will also increase the frame height a bit to work better with thicker material.

While it does not capture all the dust from the saw (I don't have a single tool in the shop that is 100% effective), it is definitely much better than not having it at. If I had to 'guesstimate' it's effectiveness, I would say it collects about 85-90% of the dust. Based on how bad it was without it, I am pretty happy with the results.

Thanks Jeff. I have been wanting to add dust collection for this 'messy tool' for long time.

Do you never make miter cuts on your Radial Arm Saw? BTW, my dust solution was to put wheels under mine, wheel it out onto the driveway, point it away from the house & cars, and blow it off with the leaf blower when I'm done, before I wheel it back into the garage / shop.

William,

I have not made any miter cuts on the RA saw. I usually use my mitersaw or when appropriate, my table saw for mitered cuts. But with that said, If I needed to make a miter on the RA, I would take off the attachment and make the cut(s).

I like your solution as well. :)

Very elegant solution. I particularly like the holes in the fence; I get dust buildup there all the time!

Thanks. There is enough vacuum from these holes to hold the workpiece while cutting (although I never rely on themto hold the piece in place while cutting) Overall, happy with 'suck' performance…...

This one will work!!! I've got something similar. The big hoods do not work because you can't get enough suction by the blade. I made the big hood first.

QueTip,

That is a really nice solution. I have a couple of questions as I am looking to build my own.

1) What is the size of the PVC that you used for dust collection?

2) Do you find the hose from the blade guard to the dust collector does much good?

Again, beautiful work! Thanks for sharing.

Dwain,

Thanks for the compliments. Appreciate it.

1) What is the size of the PVC that you used for dust collection?

Chris - The PVC that is coming off of blade guard is 1.25" The galvanized pipe going to dust collector is 4".

2) Do you find the hose from the blade guard to the dust collector does much good?

Chris - That is a good question :) I did not do any tests with and without the blade guard dust port to know if I was losing collection or gaining collection. In order to determine this I would need to run a couple controlled tests where I collect and measure dust collection with it hooked up and without it hooked up.

With that said, I don't see much 'uncollected' dust left on the table in the configuration that I am using right now. (I guess that means it is doing no harm even if it is not necessarily helping the cause.)

Take care
Chris

1.25 sounds right coming off the blade guard. The main pipe is 5 inch green pvc used for waste pipe. Cheaper & fits the fitting kits I bought.
IMHO the hose coming off the blade guard makes a difference. You will know when it falls off sometime

I thought about using PVC instead, but was concerned about static electricity that is associated with PVC.
