Avid CNC Ep2: Dual 4" Dust Shoe - 341 

PLEASE make a video on how to connect the Xbox controller!!

Jay, I smiled when you were talking about the various brushes you ordered until you found one that worked. When I am working out the details on my benches and tool storage, I end up trying so many options before getting it just right. In the end, I usually have a box of stuff that failed and not worth sending back as I have usually damaged or somehow modified it. If we can offer our subscribes any value, it is time and money-saving not having to work the bugs out. Love your shop and set up, keep up the awesome work. Ron

Looks awesome Jay! I have been thinking of remaking my CNC dust port.

Nice build, I use a similar setup and I use a cord with a counter weight on a pulley attached to ceiling to lift and lower the extra hose as the CNC moves. Keeps it out of the way and reduces stress on the connections.

Really loving the content you're putting out recently; it's interesting while being down to earth and enjoyable

I have a very similar design on my Avid CNC setup, 3/4 ply, etc. I too had a screw into the plywood through the relief cut, but the eventual vibrations from cutting/etc made it to loose one day and it fell off the spindle. I cut a pocket out of where the screw's tip reaches and replaced the screw with a 1/4x20 bolt & jam nut. I made the pocket big enough so the nut could be held with a small wrench while tightening. I've never had it slip/loosen up since! My have just been a bad piece of ply, but figured I'd throw this out so others can learn from my struggles

I wonder if someone could replace those legs under the CNC with a full sheet plywood rack. Since plywood and CNC machines go together, and a flat-laying sheet could easily be pulled out and lifted onto the machine, I'm surprised consumer-grade CNC manufacturers don't consider this

Jay - so many wonderful tips in this video. Loved it. Thank you. Enjoy your gorgeous new CNC!!

Well Done! Adding dust collection to my CNC was the first indication that I needed higher ceilings in my shop :)

Hi Jay. Thanks for showing the process rather than just the final result. All to often people can get frustrated on their projects because they can't get finished results on the first try. It's nice to see how the empirical method works with someone who knows what they are doing. Also, to mount the pants connector, you might try cutting a plate to hold it similar to what you have done for your top plate and then mounting this plate to the top (now middle) plate with some dowels with one end on the corners of the current top plate and the other on the plate holding the pants connector. If dowels wouldn't be stiff enough you could probably use some allthread and jam nuts for standoffs. I did something similar on my Shapoko to keep the dust hose out of the way without hanging it from the ceiling. The Shapoko is a much smaller machine, though.

Just made this for my 8.7hp spindle - adjusted the hole size to 3.358". Thanks Jay!

I love the remark..... " I absolutely hate dust, and this thing Sucks..." Well done on the build. Room for improvement if desired. Thanks Jay

my avid is shipping in July 21. great videos. big help to get me started.

Maybe mount the splitter at the ceiling and run two 4" hoses down to the head. It may make it easier to work on later.

Some years ago on a ShopBot forum somebody actually put some air controlled metal dogs into their spoil board for registration. They would turn on the dogs and they would pop up they would put their wood into place and then they'd turn off the air and the dogs would go away but they would turn on the vacuum table to hold things down so I thought that was a very interesting way to do registration dogs. It made a very fast in order to change the new parts but they were matching out a lot of the same thing. Great video thanks again Take care.

For the first 75% of the video, I had little idea what this project was about. But I was sure intrigued by the explanations and examples. Love your videos Jay!

Jay, you just keep getting better and better at this. Great production.

Very nice, heavy duty with the 2 4" dia hoses straddling the spindle!! if you have concerns bout your spindle clamp and the plywood, install a barrel nut in the plywood, will last forever, or almost forever.

Hey Jay. For the router clamp part you can do a pocket for a square nut. Then drill a hole for the bolt.

Jay, love your problem solving process~! Very inspiring~! Thanks for the "class". I'm interested in seeing what comes out of your shop from the CNC.

Great job on the dual port Jay! Would of liked to see how well it pulled up the dust between the cuts? You never seem to have enough suction to get it all up. I have the same spindle on a desktop pro with a 2 1/2” hose and a shop vac. Used clear polycarbonate and a similar brush. I made a groove in the Poly to push the metal beading around the edge. Works well you may want to try that on dust collector 5.0. Stay Healthy.

Great Video, I have been looking for a good 2 port shoe design for my AVIDCNC. I use 4" rigid light weight drain pvc drain pipe about 32" tall attached to the dust port on the shoe, to get over the top of the z axis before going to flex. I then used a rigid mount coming off the spindle mounting plate for that pipe. Hope that makes sense. It a very sturdy mount. Look forward to making this shoe. Thanks for sharing.

If you're concerned about the clamp screw, there's a T nut, usually a bit of rod with a threaded hole in the side, cross drill a hole and insert Alternately a square nut inserted across the hole For hose support, what about extending the plate to the right and adding a vertical support, not sure if that would add a twisting motion as the weight would be on the router collar.

the short brushes might work if the dust shoe was mounted to the x-axis instead of the z-axis so it was at a constant height from the work piece

Easy ans solid solution for thre clamping: Use a bolt, mill a perpendicular slot for ta square nut in your board and you have a solid clamping solution. Like your videos:-)

Don’t want to or have the desire to know anything about CNC. But it’s really cool to find out about it and the solutions you come up with for it.

Hey man Just following up once again. Really hoping to hear from you in regards to your cut files as well as where you found the brush Thanx so much man

Interested how this goes. I always had better luck with a shop vac and separator cyclone than a dust collector. Suction pressure worked better than volume but let’s see how this goes.

Neodymium magnets are usually metric in size no matter how they label them.

Thank you Jay, great vid!

When and if you order the dust shoe brushes, order 1 and 2 foot sections, not a full one piece 5’ section as the long tube mailer has a very expensive shipping charge!!!

Well thought out and explained. Seeing your iterations will keep me from going through the same steps. Also, hanging your pants on the rafters would reduce suction a bit since there is more friction with the 4" hoses. SO...Your plate holding the motor has many holes. Can you use them to extend a metal/aluminum support to your pants? (Jealous of your huge table!)

Last brush looks alot like some material we used on large aircraft with moving horizontal stabilizers..Used as dust / debris barriers...

Just a thought...is the spindle sensitive to static electricity? Those hoses on each side will produce a good amount of it.

Awesome work Jay! 😃👍🏻👊🏻

Did you ever find a more permanent solution for attaching the pants wye to the spindle? I'm building this dust boot at the moment for my Avid and was wondering if you're still using the bungees or if you found a better solution.

Do you remember which package the "AVID CNC" logo plate came in? The PRO4824 I just received doesn't seem to have that.

Hey Jay! How many amps does this thing pull? Any special shop electrical advice on how many amps I need to run a midsize work shop? Thanks!

This may be a strange question. What do you use to clean the sawdust around the shop? I buying a 3hp dust collector and was thinking of buying a hose reel.

Hey Jay! I’m busy working through this series. Great stuff man. I haven’t read all the comments, so you may have answered this already, but do you have links for the brush you ended up using. That looks super solid. Also, where can I buy your cut and project files (If available that is) I am in the process of upgrading my avid 4x8 and I love a lot of your methods here. I’m just adding a vacuum table as well.

Can you share the specs on the brush strip? Is it ever too stiff that it interferes with a Z-axis plunge? I have the same machine and I am going to make something like this, but instead of 2 x 4" hoses I am going to use a 4" and a 5." I've read that it's very important to match or slightly exceed the main duct diameter to the combined areas of the inlets, and that even the reduction in area between a 6" main duct and 2 x 4" inlets is enough to cripple the air flow to the collector (especially if you want to collect fine dust and not just chips.) This information is from a website by a man named Bill Pentz, who has almost a religious zeal for dust collection.

Love your Lions tee. Being born in Portsmouth OH the.m a nd the Bengals are the two NFL te a ms that I follow. As you peobably know Portsmouth OH was the original home to what is now the Lions and there orginal home field "Spartian Stadium" is still standing and in use even today.

I am such a child. I couldn’t stop seeing half a tin man peeing on top of the spindle area.

Nice job, gives me some ideas for mine.

Jay. where did you get the addin for the xbox controller for mach 4 ive been searching for that and only seen the mach 3 version

if you use thick vinyl 60 gauge+ instead of brushes it makes for a much nicer product where all the particles don't get stuck in the brush.

Nice one jay stay safe cheers from AUS

Well thought out!! Impressive!! 👍

The 12 yr old in me sees this as T-bagging the spindle.... Can't unsee this now...

I thought I was was crazy...I also always end up at version three of everything I Make..Jay why did you choose a air cooled spindle and how many watts is it?

Nice job on the video Tom, it’s not the same as Jay’s style but very acceptable!

Glad you are able to continue providing great content for those of us stuck at home. Thanks! Is your wife still in national guard? Any chance she gets called up for the virus crisis?

Thanks for the informative video! How does the dust collector do when you run the CNC at the same time with another machine that requires a lot of dust collection?

Thanks Jay.

You have that huge aluminum plate that your router is mounted to. Why not drill and tap a couple of holes to receive a mounting bracket for the "pants wye" ?

How much did this CNC cost. Fully functional

What kind of tool do you use for machining?

First video of yours I've seen.... And clearly you have HVAC work professionally lol. A bit overkill.

Doesn't Avid make dust shoe for that machine? Seems like a lot of work to make one.

That’s awesome.

Is there a way to make a support frame for you pants that attaches to your top plate?

Nice. Thanks for sharing

What about using a captured nut for the screw @ 4:00

cool video...

also can you provide a link for the magnets

Frank Howath always takes his off when shooting... I don't see you doing that Jay. Too much dust lol

Jesus, that thing reminded me of the Alien laying the eggs that Sigourney Weaver had to kill....

So let's see it suck up some dust!

Don't you also want the blast gate close to the supply runner to reduce the volume needed to 'create suction'. I do not agree with having blast gates closest to the tool.

you get a like because you took inspiration from Frank Howarth. FrankMakes is awesome.

And this this sucks which is really really good!! Lol. That what he said

You would benefit from a 3d printer

LOL..... its ridiculous when you see guys that own a CNC.... and they buy cnc'd parts for it.... glad to see your not those guys....
