I’m in the process of finishing up my custom cabinet for my Shopsmith Overarm Pin router and I had some questions about dust collection.

I will be adding a Jess’Em Master Fence II to the top which has dust collection built in. My temp fence just gets a shop vac positioned as close as possible. Underneath the table will be an enclosed box for the bottom router. The back of that box has cable management behind it so I can’t duct directly out the back. Its too late in the build to make drastic changes now.

Under the dust collection box will be 3 drawers. The top one is going to be shallow and allow for an hvac 90 deg end boot. Like this one

The 2 questions I have are will a bottom feed dust port be sufficient and should it be a 4” or 6” outlet? The 6” boot i can get locally and the 4” i have to order. This thing has been in my shop for weeks now and i just want to get it done. So hoping the 6” will work just fine but am open to suggestions. I’ve put enough time into this cabinet already i want to get it right.

The 6” will give you more volume of air movement so long as your DC can handle it.

Thanks for the confirmation. I don’t have a DC yet. Lots of electrical work to do before I can put one in but its the next tool on this list. Im looking at a used Jet DC1100 converted to 2 stage or straight to a big 3hp unit. Will just depend on how much a bite the electrical takes out of the budget.

When I built my router table one of the ones I looked at was the Incra kit – and I could not believe how much space was wasted routing houses inside the enclosure. So when I build mine, there is a small compartment for the router which has a ‘chute’ that drops down to the base with a hole out the back for a 4” female flange adapter

So when I want to use it, I have a ‘T’ fitting that plugs into the flange and then a smaller hose (2” I think) runs up to my wonder fence. Works great and I have no regrets at all for not using the traditional duct work, and I have a lot of usable space in my router table

here is the chute which sucks the dust down from the router compartment and you can see the 4” hole that goes out the back. So the compartment on the left isn’t as deep as the drawer space on the right
