As some of you know, Joel Gelman and I have been attempting to make an articulate boom arm.? After some trial and error (with more emphasis on error), I think I finally got the boom arm the way it's suppose to be.? I still have more to do with it, like hook the hoses onto it at the joint, but all in all, it turned out exactly the way I'd had hoped..

the 1 PVC tube is for the dust collection, the other is for the electric power cord, and airline to feed thru. I have not attached the hoses that fit between the 2 arms at the joint yet..that's next

Looks like those gears worked out well, good deal. Did you end up using any thrust bearings between the plates?

No..actually I drilled and used an adjustable reamer to bore the hole where I could press the bearings into the plate..it worked very well and there is no sag or loose play at all

Of course.. Joel and I will be posting how to make this so anyone else who wants, can make their own.. all the details will be posted as well as where to buy the parts..

I now have 4 of the 2 inch OD angled thrust bearings and just ordered another gear. ?Those bearings will be used on the wood version of the middle pivot section. ?If all goes well, it will be possible to make a no-sag wood version of the aluminum contraption in 30 minutes with a drill bit, a 2 inch Forstner bit, the gears and bearings, and washers, nuts, and bolts. ?We will see.
The hose is on order. Two options were selected. ?One was more expensive but had the ability to stretch and compress from 12 to 2 inches instead of 12 to 6 inches. ?The idea is not have resistance to movement of the articulation.

Basically a more simplified version. which is a good thing..

Looks very good. I have two questions. One, I can't quite get my head around the gears function in the knuckle joint. Is there a reason a single pivot point won't work? Two, I'm wondering how that much extra hose is going to effect performance of the vac.

Single pivot will not allow a full 180 degree articulation unless 1 arm is above the other, but then that does not work out well for the hose. ?As for extra hose, for any boom arm, you need hose going from the vac to the boom arm, across the boom arm, and down to the tool. ?Smooth pipe is better than flex for maintaining CFM.?
With this boom arm, you will have the flex hose going vac to the boom arm and from the top of the boom arm to the tool, but within the boom arm, you have smooth wall pipe instead of flex hose (except at the mid pivot point.

What was your final? boom arm extended length?

Randy, That is a very impressive build, It looks very well thought out and assembled. Where I don't see the need for one in my situation, When you list the build, and parts I might just give it a try and do it for fun Again well done. Glen

For the mid-section of what I hope will be the super-easy-and-inexpensive-to-make-in-your-shop version, I made a quick demo of the plan for the pivot mechanism (gear will be used but omitted at this time). ?In picture 1, you see a 2 inch Forstner bit being used to drill partially through one of the pieces. ?The center indentation can be a guide for the drilling of the smaller hole in the middle for the bolt. ?Another way to insure a dead center hole is to clamp the workpiece, and change bits without moving the wood. ?Figure 2 shows a nice fit of the 2 inch OD angled thrust bearing. ?After the hole is bored (figure 3), a hole is bored in the other piece of wood, and with washers, and a nut and bolt, the units are assembled. ?For those who do not want to deal with seating bearings in aluminum, this bearing method may work well. ?I just need to make sure there will be adequate strength in the wood.?

For me and the boom arm shown, its 107" long, extended..it hangs directly in the middle of my assembly table.? This boom arm Joel and I are doing, anyone can be make it to whatever length they need.? It's all about how long you make the arms whether they be longer or shorter.

I will say, the seating of the bearing in the aluminum took a little time.? I used 4" wide x 6" long x 5/16" thick 6061 aluminum plates.? I put some green masking tape on both plates and used CA glue to glue the 2 plates together so they would not move.? I used a 15/16" drill bit ( bearings are 26mm in dia.) and drilled the holes on both ends of the plates,? Took a chisel and separated the plates after all the holes were drilled and then used an adjustable reamer to ream open the holes drilled for the bearings until the holes were just right and pressed the bearings in..The are seated very tightly and will not budge.? This is what prevents the sag of the arms when assembled?

Randy,
Well done. Looks great. What kind of reamer did you use? Ones I have seen work for thru holes with adjusting nut on the bottom.
