  1. Instead of a hand truck consider using the T-slot extruded aluminum systems that many carts are made of. This is a very versatile system that can be used to make up almost any configuration and can easily be modified as your needs change. Go to Youtube and search for sound carts to see some examples. You can also go to this site's gallery (upper left corner of main page - click browse and then gallery) to see many different examples. The t-slot systems are a great way to go. There are many t-slot vendors. One of my favorites is https://www.tnutz.com/ On youtube and also in the gallery, you will see examples of road cases and other systems mounted to the t-slot frame so that equipment can be attached and removed as required. Here is an example of a road case on a shelf. I don't know what is holding it in place.
  2. Yes, it could be used for cooking exactly that way and still is. It's pretty much a cultural difference here as well. Wax paper hasn't been a common commodity in most kitchens for a couple of decades. It was the sandwich wrapping paper back in the day, but was replaced long ago by plastic wrap and sandwich bags. We have it in the drawer and find the odd use for it. But I would guess most younger adults never heard of it.
  3. Does the collar tighten up and stop twisting or does it keep turning? If it keeps turning, the threads are stripped. You'd have to take it apart to see if one or both parts are stripped. If it stops twisting, then the threads are ok, but the bushing is worn out or broken. Either way, un-thread it and take a look to see what part is bad. See if they will sell you parts. It could be the bushing is just out of place and needs to be set back correctly. [edit] I don't have that pole, but in the pole I have, there is are two plastic bearings at the bottom end of the tube. These bearings slide between two ridges on the inside of the tube. They prevent the tube from rotating. If those bearings broke then the tube can rotate. It would be my guess that this is the most likely reason it is rotating.
  4. Well done. No, I didn't make it. I wanted feedback from you first.
  5. That's unfortunate. So close, yet so far.
  6. I made a .5 mm walled tube out of copper and one out of aluminum (I don't have brass). I struck a flat putty knife edge with a hammer on the tube. It required quite a whack to get it to dent the same amount. It also distorted the tube into something of a oval shape. I'm thinking your tube is also distorted. The sketch is what I propose. The internal mandrel will be made of steel. The outer mandrel will be made of aluminum and lined with moleskin (is moleskin understood in the UK? It's a soft, thick fabric with adhesive on one side to be used on foot sores). The internal mandrel will have a slightly smaller radius than the I.D.. It will be ground down on the sides (dotted line) to make it easier to fit in the tube and get past any distortion of the tube. The end will be filed and sanded down (not shown) to provide a soft radius to prevent a sharp edge from being made inside the tube. To keep the mandrel flat, there are two support mandrels. One is under the tube. The other is on the far end of the internal mandrel. I have them drawn backwards. The longer outer mandrel should be under the tube. The shorter mandrel will .5 mm taller to compensate for not having a tube under the far end of the mandrel. Once set up, you strike the flat surface of the mandrel with a hammer. Do you see any issues with this? I will test it to see if it does any good. Having seen how much force it took to make that dent, I'm hesitant about success.
  7. I'm curious about this. I measured an Octava and it has a 2mm wall thickness. I tried a test on an aluminum and a copper tube that both have the same wall thickness. I placed a needle nose pliers on the tube and struck it with a hammer pretty hard, I can only scratch the aluminum. I can make a small dent in the copper (nothing like shown in Matt's picture). Even with the small dent, the tube is already out of round. It now has a slight oval shape.
  8. Very good. Also, please tell me the tube wall thickness. I want to try to duplicate the problem and test the mandrel.
  9. Yes. It's like buying a mixer. You now have 5% of your kit.
  10. Matt, please go cautiously. You can dent it in the other direction and make things worse. Normally, dent work like this is done with a backup on the opposite side of the mandrel to prevent mis-shaping. As said, ideally, the mandrel has a slightly smaller radius than the inside diameter. On the outside, there should be a backup mandrel with a soft protective layer (leather) to help keep the shape. I like to fabricate. I have a mill and a lathe. I would be more than entertained to make the mandrel and backing mandrel for you at no charge. Hey, I have time on my hands and I need to stay busy. So don't hesitate. If interested, I need a fairly precise measurement of the inside diameter and outside diameter.
  11. Agreed. Iwantoknow, I'd ignore the popping issues for your evaluation. What you can take as a lesson is how important it is to have a production mixer person on set to avoid these issues. That video is really unfair to a couple of the mics because no one was monitoring the session and allowing them to perform at their best.
  12. Here's a video that provides a great comparison of how these microphones perform in a noisy environment. Check the performance in the laundry room and in the living room with kids playing. The E6 is quite disappointing because of breath popping issues. I'm surprised it is performing that poorly. I think he has it too close to his mouth. Perhaps a foam overlay as the DPA has would correct that. The DPA does very well. Skip to 2:27.
  13. I understand you won't be using the lav experiment, but for the record, I'm retracting my statement about side fire vs end fire. I've had side fire work better than end fire in this application. It just depends on the microphone.
