The back story -

A couple of weeks ago our church bought a new camera system for our live Facebook feed and it includes a control panel system for live streaming and 3 new cameras. The cameras mount on rigid steel brackets and two were mounted on columns on the side walls with one on the back wall above the media booth. So the first Sunday morning when these were set up and ready our associate pastor had the pulpit so our pastor could babysit his new 'toy'.

After the first service with choir and piano/organ I asked our pastor how the cameras worked and he was pretty pleased. Then, we had the second service... the one where we have the live band and far more lively music (I play acoustic guitar in the band). Music like bass guitar that can rattle the ceiling tiles. So I asked the pastor how he liked the second service and he was dejected because the two cameras mounted on the side wall columns were vibrating too much to even switch to them. We like our music loud, I guess!!

They added screws into the column mounts, locked everything down, added screws to the cameras, and nothing worked. I told them we need isolation mounts but nobody knew what I was talking about so I didn't push it. I recognized that the problem wasn't the mounts, rather the problem was that the sheetrock around the columns was vibrating and resonating with the music. That meant no matter how hard you locked the cameras and their mounts down they're still going to vibrate. So Monday morning I sent Bro Terry a link to some isolation mounts and asked if he wanted me to make some to which he quickly replied, "Yessssssssssssssssssss!!!" The ones in the link I sent were $500 each, btw.

This will take two posts to get the photos in but basically I drew this in Fusion 360 and cut them out of Baltic Birch since I have tons on hand as cutoffs from all the Longworth chucks I've cut.

Drawing in Fusion 360 -

Plates cut on the CNC. This can easily be done on tablesaw and bandsaw, or with a template and router, etc., but I have the CNC so that's what I used. I also used the CNC to mark where to drill holes for the cable clamps.

Plates and cable clamps. I drilled the holes on the drill press and split the pieces on the bandsaw. I could have done this with the CNC but chose to use the other tools instead. I did use the CNC to mark where to drill the holes and cut each piece, though.

Cable clamps cut -

Gluing the cable clamps in place and using a drill bit for alignment. I had predrilled the plates so this made it easy getting the clamps in the right location.

Clamps finished and fixed on the plates -

Knobs cut on the CNC. Again, this could be done with a bandsaw but more consistent and much easier on the CNC.

Ok, I'll do another post shortly with the rest of the photos.

I used vinyl covered 3/16" wire rope cables and cut them to about 6" each piece. I cut a spacer to place between the plates for consistency between each camera mount. One side note - I couldn't cut the cable with anything I had so I had to buy a bolt cutter. Even that didn't want to cut this stuff until I realized that when I first cut the vinyl with a razor then the bolt cutter had no problem cutting the wire. In every case it cut all but about two strands and cut those with a cold chisel on my vise anvil. Any project that requires the purchase of a new tool is a good project!! :grin:

Here you can see the camera mount threaded lock, just like on a tripod -

The top plate where the camera mounts has a floating nut to hold the threaded lock and allow for secure mounting of the camera -

Camera with isolation mount. After our first test we realized that 8 cables were too stiff so I took one out of each quadrant.

Comparison grabbed from monitor shows how still the view is on the left and how the right one is moving. It was actually worse than this but this is the best I could grab in a video. Also, this was just a CD playing and not the live band which I understand shook the columns much more than the CD.

I'd have to say this is a successful project in that a simple, low cost solution, to which I could provide a solution in a couple of days, solved a problem that would have been an ongoing issue. And it was a fun project, too! I had the opportunity to design, engineer, and build something I've never tried and it worked. Hmmmmmm, I wonder if there's a market for these! LOL!

Pretty innovative Dave . Did you come up with the idea of using cables ?

I wish, Rick. But no sir, I had seen mounts like this before to take the shock out of mounts and found this one online for $500, which is the link I sent our pastor.

I actually took one back and replaced the 3/16" cables with 3/32" cables to see how that worked and they turned out to be too lightweight. So I am taking one back tomorrow with two 3/16" cables and four 3/32" cables to see if that's a good balance. When the cameras are zoomed all the way in, like if they were trying to get in on the hands of the electric guitar player during a hot lead, then there is still some very slight vibration. But our pastor is pleased with them as they are and said we'll rarely zoom in that close anyway. But I still see room for improvement so it's just a matter of his patience and my time as to whether I can keep tweaking these. Right now he's happy so they're probably going to remain in this configuration for a while.

However, I now have ideas on an iPhone mount for my CNC! I want to be able to clip my iPhone onto the spindle mount and have it video up close and personal as the CNC goes through its paces so I may be doing another one of these soon. I don't have a GoPro or I would make a mount for one of those.

Well you did one heck of a job . I never really thought of cables bent over like that to provide isolation.
I can’t get over how much they charged, ouch

Thanks, Rick!

Yes, pricey, indeed. I spent about $30 to build these although I already had the BB and I used scraps that were too small for Longworth chucks. The wire rope was $20 of that, too, so the rest of it was just hardware and paint.

Isolation Mount? I had never heard of but boy was that a clever solution and deduction to the problem!
Thanks for sharing it, now I know what an Isolation mount is LOL

That's what I call a brilliantly made device and so well illustrated. Oh for more threads like that.

Very interesting. Hope it keeps working just as well as now. Sounds like you could make some change making and selling them.

I'm saving this string for the future. I'm converting an old elementary school lunch room into a small theater, and one possible use would be to handle the overflow as the church keeps growing. They will have the same problem in the sanctuary with very loud music. I don't go there because I can't stand the volume level. Every musician I know is pretty hard of hearing and should NEVER be allowed to set the volume level. Give the band amplified earphones and let the women members vote on the volume level. Above 85 db, hearing damage occurs and most deaf musicians (most are), like to play at double that level. Which explains why they went deaf in the first place.

Very nice solution to a problem. Well done. I also like that the Church is live streaming the service for members stuck at home. I'd also like to know what they're doing to promote the livecast to potential new members. I'd suggest they have someone do an introduction to the service, an extra camera and microphone would be needed. I think that would facilitate "tuning in" to the service online. I'd also think about providing a live feed through the website as well as on facebook.

I'd also like to know how it's going finding a crew to operate the system, call the shots, operate the switcher, manage audio. Wireless mics are definitely called for, and a good audio mixer.

Not long ago, I bought three Audio-Technica PRO 44 Cardioid Condenser Boundary Microphones for our local theater. These mics attach to wall or ceiling, have some isolation qualities and are amazing for picking up things like the sounds of the members singing along. The audio guy there was amazed at how well they worked, and didn't install them until he spoke with the company tech rep at a trade show. They are really ribbon mics, require a bias supply from the mixer. They feature a gold ribbon to which the bias voltage is applied, which is why they perform so well. I loved the little theater (a converted WWII USO building), but couldn't ever hear very well. But the three mics ($99 each) make it really easy to hear. Just a heads up on the audio, which is a huge issue for older parisioners.
