"Old" Boom arm height and radius

[Sean7a]

Does anyone have an old boom arm setup in their shop?  I currently only have CT 26's on the sales floor with boom arms, no 22's or 33's.

I'm looking for the top height of the boom arm form floor to the tippity top of the arm when attached to a CT22.  Also, curious on the "radius" or the distance measured forward of the boom arm from when it starts to arc in from the middle of the arm.  In other words, from where the arm begins it's bend inward to where it stops.  What is that length?  About 2 ft?

Thanks in advance gents.

Hey Sean,
I get approximately 83" from floor to top of pipe section plus around 2 1/2" more for the hose holder. The arc of the arm is approx. 44" from upright pipe to the tip, and the last bent section is approx 2 ft.
Mine is on a CT 22

Sean, my CT22 has a boom arm whose original height was 86".  I had to cut 5" out of the lower stanchion to drop the maximum height to 81" to clear the central beam in my shop which happens to be over my MFT/3s.  That necessitated re-drilling the stanchion for the through-bolt.

Mine is more like 81" -- 83-1/2" to top of hose holder if/when mounted vertically.

You guys rock.  Thank you

This is a great topic - I've been wondering about this myself, as the headroom in my basement is limited (people must have been shorter in 1927).

As long as we're talking about the boom arm, I'd like to ask those who have it a bit more: what sort of practical working distance from the base of the boom arm is there, across an MFT/3?

Here is the set-up that I'm working towards: a Kapex table with Kapex on top and CT22 under it; boom arm coming up and over; and a MFT/3 on either side of the Kapex table (that is: 2 X MFT/3).  

This gets much inspiration from the set up of Rey Johnson:

except that I won't be mounting the MFT top sections onto custom bases.

I'm imaging that the CT22 with boom arm will live under and behind the Kapex table, and that the boom arm will serve work performed on either MFT/3 table on either side of the central MFT/Kapex table.  My question is: Is the reach of the hose coming off the boom arm adequate for all operations with any tool, on any part of any of those 3 (2.5?) tables?

Thanks.

Keep in mind that the CT22 is on wheels, and as such can roll wherever you need it.  The boom arm is limited in its swing arc to keep it from flipping over to either side.  I have two MFT/3s, with my CT22 located to the left side of the right MFT/3, and from there it can reach pretty much anywhere on the two MFT/3s, even when I'm using the TS55 on the guide rail on the right-most MFT/3.  If I were to add in a Kapex MFT between the two MFT/3s, I rather think I'd have a challenge getting the arm to swing sufficiently to hit everything from one location.  Again, that's why the CT22 has wheels.  (Then again, you could spring for a CT36 to add to the collection...)
