Good engineering. Your clear description before each construction step is very effective.
i have seen the cosmas video and now yours,and it tells me as a carpenter with no programming skills, you don’t need programming skills iff you understand basic mechanical engenering ...coool video and inspired for my new shop
Very nice project. I like how you aligned them so the opening was down-hill when they were closed. That should clear out any chips that get stuck in the gap each time you close the valves!
Glad you noticed :)
Great idea to use the bowden cables (I think that's what they're called) for actuating the blast gates, now you need to add a couple of micro switches to the blast gates to turn on the shop vac automatically when you open one of the blast gates.
Thanks for sharing the video. :-)
I literally just finished making a set of 4" blast gates this morning, and now I want to upgrade! Havent even installed them yet haha. Great video, and really cool design - thanks!
Nice to see you back. Very cool design! Thanks for sharing. Cheers! 🍻👍🏻😊
Great idea using those cables. I need to see if I can incorporate that into my future mobile all-in-one workbench build. Subscribed!
Very neat design and build. An enjoyable watch.
This is amazing
Nice to see you ventured over here Joe!
Pretty clever! Was looking at some electronic options but buying them is cost prohibited and making them would take too much of my time. This seems like a reasonable solution.
Cool video and an inspiration. Old guys like me may forget which way is open or closed even though they are marked/labeled. I would add color. Simple dots of green and red on both the blast gate and the control. That way with just a simple glance, I would tell if it was open or closed. just a thought.
Very cool
That's pretty amazing! Nice job! 💪💪💪
Nice video, I will be making some of these!
You could have just put the sign on the other side and flipped it the other way up to sort out the open and closed thing.
That was super ingenious
Perfect timing to implement in my dust collection system!
Nice job! I am surprised you used two cables - these cables are designed to both push and pull, so you could've just used one. I'm sure you tried it with just one - what made you go to a two cable arrangement?
No, you can't push with these cables. As soon as the cable leaves the sleeve it is unsupported. No way to push an unsupported cable.
@@JustinDepew Ahh, thanks Justin. Good to get that straight before I start expecting the impossible!
@@JustinDepew I was thinking of either using a return spring, or a solid "push-pull" inner cable in a supported housing, like on a mower throttle.
Gotta love the way you think though.
*edit* Just realized it would be hard to get a solid cable to push that long of an arc. Still think the braided cable / return spring idea might have some merit.
Who else watches the full ads to pay him back for dropping his mad knowledge?
Awesome , what a great Idea
Nice design Justin and a good execution, as just a suggestion you could wax the gate rails and the pulley.
Thanks I actually did do that, just did not video it.
Très bien fait beau travail félicitations
Justin thank you so much this has helped me alot
These are awesome. Great job!
That was inspired! Great work, so very cool.
great stuff. you are inspiring
Sorry this is off subject a little, but what 3D printer do you use. I really enjoy your videos, and were absolutely amazed at your CNC dust collector that you made. Thank you
Hi Chris, I have the Prusa i3 MK3. It's been a great printer for me.
I love this approach. I am working on implementing this myself as my ceilings are lowish so I ran the main dust collection trunk around the sides of my garage, so blast gates are hard to access behind machines.
I was wondering why you decided to use 2 cables rather than some kind of a spring return? I had been thinking about using a spring to cut the number of cables used in half, but then I was wondering if this might tend to bind if the force is off axis a bit. Did you try this?
I have not tried the spring return. It does cut the cables in half, but you do need a mechanism to hold the gate open when in use. Check out Cosmas's video as he made some blast gates like this. I'm sure they would work just as well.
Super great !
This is a great design though I need 2- 10" versions, 2- 8" versions, 2 @ 6" plus 3 @ 5". That's a lot of monkeying around but seems like it will be enjoyable.
well made
Great project. You shold do more videos
I wish... Only so much time in a day!
@@JustinDepew yeah i understand you.
We use a similar set of hardware to your skate wheel axle in our awards business, it's called a "ferrule" - if you google "1 1/4" Threaded Trophy Ferrule" you'll find it
Thanks I didn't know that's what it was called.
Genius!
Really f in cool!
This would be useful and I would be able to make if I had a 3D printer.
Nice build! I just finished modifying my TS blast gate to operate with your cable brackets. It works! Only problem is the cables I have are from a bicycle and are not long enough to reach the location I have selected for the control lever. Where did you get those long cables?
I got them from ebay. They are go kart throttle cables.
how did you connect dust collection to table saw? any pics.very Clean workplace.i thought you had a big place .
Very nice project. Where does one purchase that type of cable?
I bought it off ebay.
@@JustinDepew Thanks.
Could have put the open sign on the other side and it would have flipped the handle 😜
Wish we could buy plywood like that here.
Where are you?
@@JustinDepew The tip of Texas by Brownsville. Have always watched your videos and really appreciate all the effort you go through to make them.
What paint do you use for the red finishes?
Rustoleum Enamel
When it was backwards you could have just put the label on the other side
excellent work my friend, almost as good as i am...LOL...just kidding, no where near your skill level. I'm just starting out in woodworking and like trying to make things i need as you do...I was wondering if you could explain or give the formula you used to sized your pulley (circular rotation) to rotate the distance you needed to close your gate (linear motion) pls...i would appreciate it.
Great question. The only formula you need to know is the circumference of a circle or C=pi*diameter. I wanted the pulley to rotate 1/4 of a turn or 1/4 of its circumference. The distance of 1/4 of the circumference needs to equal the travel of the blast gate. So I measured the length of the blast gate travel and then back calculated the diameter of the pulley. (Pulley Diameter) = (Blast Gate Travel*4)/(pi)
@@JustinDepew Thanks for the reply, I should have known this but been out school for some years now and you know the old saying, "don't use it, you lose it"...LOL Keep up the good work and videos my friend, I'm learning a lot by watching you.
Nice job, but why? It seems to me that even with your tight space, you could have easily mounted a blast gate adjacent to or on your machines that you could actuate by hand or with a simple, short pull rod. There is absolutely no reason at all from a fluid dynamics standpoint to put blast gates anywhere along the run of any trunk line. There will be zero air flow in a trunk if all tool-mounted blast gates on that trunk are closed. With no flow, there is zero impact on flow (CFM and SP) in any trunk being used or anywhere in your dust collection system. I believe Bill Pentz erroneously suggests somewhere on his website to put blast gates on trunk lines, but he is wrong.
Even so, the blast gates aren’t always that easily accessible depending on your layout. My table saw blast gate is behind my table saw underneath an outfeed table and it’s really inconvenient to get there.
