« Part 3: I'm all Oak'd out........ Part 4 of Miter - RAS - Drum - Wall series Part 5: Done enough for now - with video.... »

First off – thanks to the folks who are following along this crazy journey…....appreciate it….......

Put the workbench finish on the tops and got the main 8’ table attached. This had to be squared up to the RAS so had to be done first. Now I can focus on the miter saw.

Dust collection on the miter saw is always marginal, and I’ve been thinking about this for awhile…...time will tell how well it works….

Started with a spacer piece to plug the big gap in front of the saw:

This should allow the saw to work correctly and not spew dust out the front….....I think.

Next – built a dust drawer out of scraps to sit under the saw:

Lastly – built a deflector behind the saw to divert the dust down. This will not be that clear in the pictures, but used some gray rubber sheets to help with the process. The idea is to design a system that works for all cuts, including miters…..time will tell.

The deflector box is removable – here it is on the bench:

And the underside – the rubber sheet is stapled on:

On the saw – will take some time to work out the exact details:

First tests look good – lots of dust in the drawer – still use the dust collector on the port, which catches most of it, so we just need to collect the rest…..:)

Thanks for looking….......

good way to find the problem here
seal all the gaps as they show up
one by one

maybe a collector in the drawer too
like a ‘y’ in the dust hose

Thanks David – I’ve considered the 2 hose approach – and may do that – but can never get it all when doing miter cuts….Will try this awhile and see how it works…...appreciate the input!

Jeff it looks like you put a good bit of thought and effort in the design. I hope it reaches your expectations. It look like it will work to me. Keep us posted on the results.
Your getting a little closer….....

Unique design; I will be interested to hear how well this works for you; it looks like a good solution for DC when doing mitre cuts, but at least with my mitre saw, a lot of the dust would simply bounce off your shroud and get thrown back towards me.

Very interesting setup. I think I like it. Let us know how it works for the long term.

oh yea. gr8 idea. this is a lot more compact than a big-ole “hood” in the back. the drawer idea is very simple, and should work well. thnx for the post

This looks great. I hope it works as well as it looks.
Even if you have to replace the drawer with a vac, it looks like it would work better than standard rear exhaust.

Please keep us informed,
