So, a weird one.

I would like to suspend a tube at right angles, from a roof beam which is canted over about about 20 degrees.

It’s so I can attach some overhead drum microphones for a semi-permanent installation.

It’s in a low roofed room which runs across the space so there’s no room to mount it to the walls either side. The beam runs from front to back and is supporting the roof joists, so I don’t want to go drilling large holes in it to run the tube into it.

To make things worse, there’s not much headroom so mounting to the beam underside might be difficult in terms of bonce clearance.

Any ideas? I was thinking of getting a bit of tube and mounting it to a handrail base mount such as this:

Or fitting to an angled ‘shim’ and then using something like this:

Can anyone think of any ‘off the shelf’ suggestions?

How big is the tube, are we talking toothpaste or trains? How big is the beam, what sort of angle etc?

A photo of where its going might help. If it is scaffold pole or similar as appears from your images above, there are fixings for that.

Used the above for cables in the past. CEF do some other styles for fixing things to beams / girders. They are usually called beam or girder clips or clamps which should help you Google a type to suit.
Hope this helps 🙂

Edit: I think there are also beam clips available for unistrut systems that I’m sure I’ve either used or someone has installed for us in the past.

Thanks – will take a pic later. Well, I was thinking either scaff tube, or I have 1.5″ OD tubing from drum racks, or 1″ tubing from cymbal stands – either would work. Beam is at about 20deg.

Hmm, can’t picture it – needs to be perpendicular at 90 deg to beam.

I did look at things like that – there are theatre rigging clamps too, but I think they’re meant for steel beams, rather than wooden ones. I’ll have a look on the site though – bound to be something.

Basically it won’t need to support masses of weight once it’s all in, but getting it in appears to be the problem at present!

Ah, a timber beam. Just trying to make sure I understand he question: you want to fix a tube to the side of the beam, and the tube should be horizontal, but the side of the beam isn’t vertical?

How far will the tube stick out, and how much weight will go on it?

How deep is the beam, ie, how high is the face of the beam you’re fixing to?

Does it have to be a tube? Could you screw a short length of 2×2 timber onto the side of the bean, and a piece of plywood onto the side of the 2×2?

Correctamundo. Sorry if that wasn’t clear from my initial post!

So here’s a quick pic showing the setup:

A close up of the beam:

And what I’m sort of trying to achieve:

I’d suspect no more than 3ft or so, and in terms of weight, a couple of overhead mics, and their clamps and whatever I can find that allows me to clamp to the tube (hence the slightly limited choice of tube diameters).

How deep is the beam, ie, how high is the face of the beam you’re fixing to?

Probably 8 inches or so.

Hmm, no, but it would make like more complicated as I’d then need to find something else to attach the mic clips to.

Loop of brake cable and a solderless nipple?

I’ve just put a shelf up in the garage above a window. One end is on a wall where I could stick a bracket, the other end has an eye into the ceiling holding the shelf up with the brake cable through a couple of drilled holes. Barrel end at one end, solderless nipple at the other.

You might need/want some protrusions on the beam to stop slippage, might be screw at the top, or a dob of sugru or hot glue.

Edit, started typing before the photos. Never mind

Ahhhh ha.

You want the pole for the mic horizontal not vertical from that beam yeah?

You could also just not overengineer it, and do something like this: https://imgur.com/tSRYgGh

You’d only need a couple of pieces of timber drilled slightly larger than the diameter of the tube and screwed to the beam to act as braces. And you could control the angle of the tube with the position of the hole drilled in one of the braces.

Ok, it’s eating into headroom… but you could keep this pretty minimal.

But then without the scaffold poles, beam clamps, brake cables and solderless nipples, it wouldn’t be an STW solution. :oD

Ooh, sir! Sorry, I can’t envisage this and the link isn’t working. Probably entirely down to my lack of practical ability though!

Yup.

I think this might the the answer, thanks! It might even improve matters as being slightly lower than the beam would give greater clearance for the ‘tube’/pole.

🤣

Drill 2 holes in the tube towards one end, align holes either side of the beam’s low point, insert coach screw through hole out the other side and screw to the beam, adjust angle by tightening or loosening one screw or other…

No spoons, though. Yet…

I’d just use a piece of plumbing pipework (whatever material takes your fancy). Use pipe clamps to fix it to one face of the beam, then bend it to horizontal.

Sorry misunderstood as I’d assumed steel beam.

Solution as sketched by ambient coast looks good. Brackets from whatever wood of thin metal you have handy. Just fix with wood screws.

Other very quick and dirty solution is to strap the tube to the beam using flexible metal strapping and woodscrews (2⁰ to 30 mm long is fine). Plumbers and electricians use the stuff for supporting pipes and conduit. Could use a bit of old webbing instead or pipe clips with one on a small block to make it level(ish)

Metal strapping example:
https://www.screwfix.com/p/ced-galvanised-all-round-band-12mm-x-10m/18298

Something similar to ambientcoast but not losing headroom. Say the tube is 2″ diameter, screw a piece of 2×2 to the beam, running vertically up the face. On each side face of the 2×2, screw a plywood triangle. Then put the tube between the triangles and bolt it through. It can be horizontal or slightly down,

Or I like stevomcd’s idea, bend the pipe in an L shape and clamp one leg along the beam.

I’d use two of these

I’d want more ability to move the mics that a rigid bar would allow because mic placement is key for good drum sounds.
