a1tomo The best thing about dust collection systems is to eliminate the bulk of the fine particles that are inhaled. There are many woods that are toxic and the dust is especially so. I feel that controlling the fine dust is more important than sweeping up a little sawdust. Someday, I hope to get an air cleaner after saving up a few more bucks.

It looks like you have given a good amount of thought for your table, and am sure you will enjoy working on it. Great job!

Bogydave Very nice table.
It will make allot of sawdust.
Very versatile,

I still think you built a DARN FINE table!

But the holes do act as a knob so I can open the door.
Wow.... really got my brain going this morning.
Thanks for the observations...... and I'm sure it can always be improved on.
If it were me, I would have reversed the Y.
No big deal, someday if you get the notion, you may try it that way.

As I would think, it would work as it, but be a little more efficient with it reversed. Note the direction of the "Y"s in this diagram from a government site, actually OSHA.gov ...


or this one as another example...


also from an OSHA.gov site

Finally, for reference, here is a link to Nutone's central vacuum system PDF. On page 27 (not really a great image) it cautions about the flow in a Y connection.

I would think what you have is an extension of a system like these.
Also, many people use a shutter or valve to further direct the flow as to either make the top or bottom "suck" more.
Still it's a little thing, let's not overly dwell on it.

I still think you built a DARN FINE table!

Cordially,

reuelt - Very interesting.... I knew about the fan on the router but didn't think about the vac. system stopping it from doing its job. I might have to revisit that one. Since the router fan is at the bottom, I'll have to look and see if there is a way to built a port of sorts at the top that would suck any dust from the bit area only....and the holes in the fromt door will allow fresh air to enter the area...so the fan CAN do its job. Just have to be careful not to have too much suction so it stops the boards having a smooth glide across the table.

Wow.... really got my brain going this morning.

reuelt Hello Palmer,

Just a comment.

A vacuum port sucking from a bottom enclosure of a router table is NOT a good idea.

Reason: The router has a fan to cool the motor. If you suck from an enclosed area, the router fan could be affected by the vacuum draft and so cannot cool the motor enough. The router motor may heat up and the coil burnt.

This is a very common mistake. Vacuum suction should be done only through the dust port of the router.

Suction from the fence at the top is correct.

Sorry for the trouble
Hi Palmer,

Now THAT is a TABLE!!!

very nice work indeed!

I'm especially green with envy about the storage space!
My humble table, couldn't have storage space due to it's configuration, but I'm brainstorming that right now.

As to your pictures, I don't think it's an upper case problem... I think you'll have to wait until you get 10 posts before your album and upload a file thing is automatically incorporated.

I think you set the Y in the exhaust port coupling incorrectly though. Think of it as water flowing, from the top, it has to make one heck of a bend to get out through the sharp bend in the Y and through the rubber coupling.
You might reconsider it's use for that of a T . Also the extra holes in the front router cavity will allow air to enter, reducing the suction power. Just my observations, my friend, you said you asked for them.

Cordially,
Gerry
