Blast gate for shop vac
50mm hose size.
Back to wood…
Just had a three weeks influenza, could hardly breathe, so I thought it was time to kill the dust in my shop.
Since I moved to this shop I always just moved the hose from one tool to the other, this also means sometimes not doing it, since I am really a human, or in other words; make mistakes and are sometimes more lazy than rational.
But to set up my dust system again I needed some blast gates, since my number of tools have a tendency of growing…
Back in the shop, but we are not going to be in this part of the shop.
This post are 100% gallot free. ;-)
All kinds of high tech will be used, such as electricity powered tools. ;-)
Starting at the table saw cutting some ply – now with blade guide please notice…
In the back of the saw you see my separator blast gate that came back into function now and are the heart of the dust system, there’s a link here for that: http://lumberjocks.com/mafe/blog/26481
Drill press making 50mm holes in the ply to fit the standard hose.
Since my shop are small, I chose to stay in this size, it takes no space and are cheap.
And some hose adaptors, using a 75mm and a 50mm hole saw.
Just to show of, I use my new toy, really happy for this sander, never really understood why it was such a revolution, now I do…
Sanding the outside also.
The gate house and gate.
And lots of bits and pieces…
Now I think it makes sense.
The parts of the gate house are glued.
If you want a version where dust cant get trapped, you will need to make a gate that goes through the house.
I don’t care since it is easy to clean and I can make it smaller like this.
Make sure you got a tight fit.
Just to hold it in place while it dries I use the air nailer.
Remember to remove the gate, just in case some glue has escaped.
Then I cut of the extras, it was more easy than to fit it before.
A wee sanding for esthetics…
Marking where the hose goes.
Drilling a hole near the gate opening.
You will know why later…
Glue and the hose adaptor can get in place.
Plenty of glue to make sure we are air tight.
To make a easy open gate I drilled a hole.
And rounded on the outside.
Now we get back to it.
Marking where this hidden hole are.
Drill a hole.
Now the glue are dry so I mount the other side of the hose adaptors.
Now you’ll see why!
I put the gate in and then a rivet.
Like this the gate cant get out and it will be able to open fully due to the ‘why did he make that’ hole.
Ok this one I dedicate to our LJ buddy GlassImpressions, he made a sexy detail I could not resist on his gates.
A keep in place sexy thing, here my way with a bolt and washer instead of ball bearing and ply top.
First I drill a hole while the gate are closed, just a little down into the gate – please look in next pictures before you drill since it need to be right.
Trust me, I made a mistake my self.
Now a spring from a pen and a round head bolt.
Here you see how deep you should drill.
Then put in the bolt head down.
You can drill again where it’s open if you want a double lock.
Then the spring.
Don’t remember why I took this photo…
Now the red says NAAAAAAAAAAAAAAAAAAAAAAAAAA.
This hole were too deep, the gate will be locked permanently.
But it can be fixed…
Now a short screw and a washer to hold the spring in place.
A wee bit of grease from the grease box to make it run smooth.
First gate can be mounted directly on the disc sanders base.
The other can go on the drill press vac arm.
Easy to reach and use.
Extra bonus material.
My vac system is a mix of 50mm drain pipe and old vac hoses from the dumpster.

This time even a small video. ;-)
I kind of know this sucks…
