Swing Boom Arm
« on: March 19, 2018, 10:42 AM »
Hello all,

While I am almost done with the Kapex stand (missing a hadwood top) I worked on a swing boom arm to go with the CT-26. I want it to be able to accommodate the kapex, CNC and MFT without having to move the vac.

Here the prototype I came with so far


It is a very simple setup using a 1" electrical pipe (EMT). I will use an iVac switch at the CT-26 to power the vac and tool on a separate circuit. A 14ag power cord is running into the pipe with a wood plug to protect from wearing against the pipe. As you can see on the pict I have a receptacle (split) every two studs.

For those interested, the pipe bending specs are:

Beak - 25deg @ 6",
Neck - 45deg @ 30"
Leg -   45deg @ 54"

I have a CNC gcode file to cut the wall brackets made of BB 12mm doubled.

I'll post more picts tonight :)

Mario

I really like it. I was planning to make a wood boom arm but this is simple and works. I already have a conduit bender. The ends can just be dipped in Plastidip liquid. I might do a trombone style version with inset conduit for extension in the work space.

I thought about it. Here how I solv that issue

Wood plug with a splitter at the end for;

1) plug it-cord
2) standard cord (Kapex and CNC)

It's still a prototype. I put up an iVac behind the CT-26 already to not worries using the Kapex in combination with the vac.

Did I spot a surveillance camera there?! (I have a wireless motion-detect camera in the garage hooked up to my cellphone so I can leave my shop door open, if desired.)

What is that 20amp wall outlet intended for?

And are you plugging the auto switch into the same circuit outlets? It appears so in the photo.

Is this just for power (no mention of vac hose) or do you strap the  hose underneath ?

Yup I have a few Arlo camera watching the shop with a wireless remote lock :) I can lock unlock the door from anywhere. Mostly to check if it is locked.

The 20A outlets are 220v single phase for bandsaw, planner, jointer etc. I have 7 totals all on a separate breaker. Two are drops from the ceiling for the table saw and bandsaw. I know they don't need to be on their own, but I wire the place like I would do for myself... wait this is MY shop after all :P

@Vondawg

The hose will be strapped on the pipe using velcro bands. If you look closely to my existing hose you will see the blue bands I will be using. Bought a pack of 50 for 15$ a month ago. I am waiting on the new 7m hose coming in April. I will post picts when I get it completed. So far without the hose it comes around 60$

Wise choice, Mario.  Nothing like a belt and suspenders!  [big grin]  [poke]

Thank you Willy  [big grin]

Funny that you mention suspenders. I still have a few for when I was yuuuuge. I had to loose weight a few years ago and I don't need them anymore  [wink]

Prototype II.

I add 12" to the neck part and redo the upper wall bracket to accomodate the vac hose inside a U shape. I will post a picture tonight. I already put to use the swing arm and i love it. Plugges to the Y connector, I have a plug-it cable and a standard extension cord so I can use it quickly with any plug-it power tool and the Kapex/CNC. I might also change the extension cord running into the pipe from 16ga to 14ga since the Y connector is rated 14ga.

If you might ever consider running an OF 2200 from that boom arm, you might want to consider using a 12 gauge extension cord that can handle 20 amps.  Just a thought...   [smile]

I tried to find a 12 gauge Y with no success :( and I don`t want to add more splicing to the wires. All my 110v outlets are on 15A, 14awg as per our local regulation. If ever I get an OF 2200 I will add a dedicated 20A outlet.

Not available in Canada  [scared]

The closest I could find is the Ridgid one. Look at the price  [eek]

The new braided hose arrived this morning, I will be working on the boom arm tonight and I may just be tempted by the Ridgid option. Darn you!  [tongue]

The RIDGID cord you looked at is an all weather model and also 12 ga. conductors, both of which are good but add to the cost. RIDGID makes (or used to) another cord that is not all weather and should cost a little less. But my thinking would be if you're gonna have a triple tap and potentially two or three tools operating at the same time wouldn't you want a heavy duty cord like this and not some POS 14 or 16 gauge cord.

Understood, there will be only one power tool a ta given time. If you look at the pictures there is a Y connector (14awg), from there I will attach a plug-it cable and an additional cable to the CT hose. The reason for a second cable is to accomodate the Kapex 120 and my CNC machine which do not fit with the plug-it cable end. Only one of the cable will be in use. The two cables will be using the same 15amps circuit and the CT-26 a dedicated 15amps circuit.

And yes I am planning to use a more suitable extension cord like a 12awg. Thanks @ChuckM for the CT link. I have to confess I do not visit CT much. I'm having hard time to go to a store with the word Canadian in their banner and that sells more made in China items then anywhere. Todays reality I guess.

Last Friday I received the new braided 36mm 7.5m hose to be used on the boom arm. As suggested by Willy I used a 12awg cord instead of 14awg to accommodate the OF 2200. I found a 3 way cord for less then an arm ty to ChuckM.

Last weekend before I put the new hose onto the boom arm, a few enhancement came to my mind. While I was waiting on the new hose to come I did use the boom arm on the Kapex and for some sanding, obviously some modification were required.

Prototype II

- First I made a new set of more robust wall brackets,
- I made the bottom bracket hole larger to fit the 12awg,
- Add a notch on the top bracket to attach the new hose preventing the hose from wiggling and catching on anything,
- Made the hole boom arm (wall brackets) to sit on French cleats, that way I can move it anywhere in the shop.
- Made the beak part longer from 6 inches to 14 inches. The end was a bit too far for my taste from the Kapex.

I still have to come up with a way to keep the wall brackets tight onto the French cleats. Perhaps you guys might have suggestions. I want a tool-less way to move it.

Also I have at the end of the boom arm a wooden plug. The power cable to through the plug to protect it. The plug is a tight fit going into the EMT pipe protruding 18mm. What would you do? leave as is or epoxy/glue wood on metal.

I will post picture before and after assembly tonight.

Mario,
I like your boom arm upgrades. I'm thinking of a tall bracket that extends below the bottom edge of the French cleat a couple of inches. Then a sliding,slotted block that rides in a dado, which will minimize any torque twisting the block. Once the bracket is set onto the French cleat, slide the block tight against the underside of the cleat and tighten a knob to hold it in place. Now the cleat is locked securely onto the cleat.

@David Fox  Thanks for the suggestion, I might go that route in a near future. I put two screws on both French cleats for now. I am focusing on a few storage cabinets. I have all my clamps set on a wall and I'm frankly tired to move the hardware boxes. I hope to be done in a few weeks with some pictures  [big grin]

I do something similar.  There are no less than two french cleats separated by 18" supporting any cabinet or other structure/bracket.  The bracket with its movable cleat has a screw, usually a self-tapping flathead screw, placed such that it's just below the fixed cleat on the wall.  The screw is long enough to prevent the movable cleat from being accidentally lifted off the fixed cleat, but short enough to not contact the wall surface.  This leaves no marks on the wall or the fixed cleat, and all cabinets can be placed on appropriate cleats easily by backing out the screw.  Cabinets can be relocated horizontally (slid right and left) without removing the screw.  YMMV...

I don't have any pictures, per se, @Mario Turcot, but I do have a drawing somewhere in the files.  I'll see if I can find it later today. 

From my notes on the computer:
If using the Imperial system, space cleats at 12", 30", 48", 66" and 84" AFF, measured to the bottom of the beveled surface on the stationary cleat.  The delta is 18".  Use a minimum of two cleats per cabinet so any cabinet is supported by no less than two cleats.  Base cabinets are supported by two+ cleats plus two Ikea Capita (http://www.ikea.com/us/en/catalog/products/60263574/) legs at the front for strength and to make under-cabinet cleaning easier.  Leg height is set to 115mm AFF (level floor).  Leg adjustment range is from 110mm (4-3/8") to 120mm (4-3/4") . 

Four standard cabinet heights (Imperial):
31-1/2", 2 cleats
49-1/2", 3 cleats
67-1/2", 4 cleats
85-1/2", 5 cleats

Point of bottom cleat bevel spaced 7-1/2" above cabinet bottom, then every 18".

Mario, here is what I use for tool-less, movable french cleats. Note that the cleat uses a screwed-on base (not glued) so you can get it on and off the wall. You place the cleat on the wall, screw on the base and then tighten the socket head cap screw, which is mounted in a threaded insert, to hold it in the position you desire. I can tighten the cap screw enough by hand that it will bite into the bottom of the wall mount strip to hold the cleat in position. For heavier or longer cleats I sometimes use two cap screws.
Enjoying your post.

@mccrich Richard, many thanks for the picts. This is close from what I was thinking but a picture worth thousand words  [big grin]
This is how prototype II looks like. You can see the French cleat where the t-square is fixed with 2 screws. There is another French cleat behind the UDD at 30" apart.



Have been using it for a few weeks and so far so good. The 36mm hose is pretty heavier then 27mm hose but the 1" EMT pipe is holding very good.

Only few minor changes will come into the final version. The 12awg cable will be shortened to get rid of that loop and a good attachment system like you just showed me  [big grin]
