  1. Shut down until all can be tested
  2. Yes, that’s what I anticipated from having moved refrigerator sized furniture up/down stairs with too short a dolly vs with tall dolly. I plan on having best of both worlds.
  3. Thx David for the closeups. I think I know what’s happening. Looks like rectangular or square bar in the t-slot for drawer glide. I am doing something kinda similar in places. Steel drawer glides are heavy, for sure, so using very few of them. What did he charge, roughly, for carts like this and how many could he make in a year?
  4. Good to know since I may not be able to get larger ones. I think the ones I have are Arri and they can’t be much more than an inch in diameter. Funny, the OCD in me is designing this cart to be single handedly amenable to going up a flight of stairs fully loaded. Maybe even multiple flights, depending on your stamina. Wasn’t sure if there was a need but apparently there is.
  5. Thx David. I am learning things overall from the discourse with everyone, often in ways nobody would guess, but grateful nonetheless. As I wrote before, I wish I could see one of these carts in person as the thing I would be most like to benefit from would be close-up details not clear from photos or the video that might actually spur use in a different way. Disadvantage to this type of monitor mounting solution seems to me to be you can’t easily change the height location. Also, I am bucking the current manufacturing trend here, but it looks like it requires a lot of machining. Necessity is the mother of invention. I don’t plan on getting my own CNC machine and besides, for cost and environmental reasons, I am trying to avoid turning 40-50% of the 6061 aluminum I just purchased for 5-10$ US per pound into shavings worth 10-30 cents per pound that require energy to be consumed/pollution to recycle them into a useable form of aluminum again. looks like he also did what possibly every other aluminum cart maker is doing today by bending flat sheet to make the shelves. Not to pick on this amazing, over the top cart, but since it is no longer s available for purchase hopefully everyone will forgive me for using it as the example. With its yield strength of 40,000 psi, 6061 alloy aluminum is much harder to permanently deform than 5052 with its yield strength of only 28000 psi. But 6061 is too brittle to bend, so they have to resort to using the weaker 5052 aluminum sheet for making bent shelves/work surfaces. 5052 is fine in some situations. No need and wasteful to reinvent the wheel, or the nuts and bolts, when and if I can find an existing though obscure part that can be creatively used. It’s not easy and is harder than ever to get a patent, must be “non-obvious to a (fictitious) person skilled in the art” but if anyone thinks a design using little or no custom parts is not patentable, think again. Somewhere on this forum I saw someone belittling carts using “off the shelf parts”. The most valuable company in the world today started out using a bunch of off the shelf parts. It requires more creativity to come up with a great design without milling machines, hence why so many resort to CNC these days, often with questionable results. Steve Wozniak refered to chips as “the lumber of the computer industry”. Architects design amazing, one of a kind buildings from homes to skyscrapers using off-the-shelf lumber, steel studs, joists, beams and columns. CNC has its uses. I will have some custom machined parts but hopefully few, and patentable. There may be exceptions but I am trying to make the designs as environmentally sustainable as possible while not cost prohibitive. Luckily the two often are not mutually exclusive.
  6. Sure, I have plenty lying around I got from China when the FS7 first came out to fix the too short arm situation. But Those are only about 1” diameter which doesn’t give them much leverage/increases the stress on them. I am hoping to get some rosettes at least 1-1/2” - 2” in diameter. Anybody know of any that size?
  7. The reason for the thicker frame was to provide a better/easier means for protecting the screen and or the rear connection. I had misspoke and written 3RU but it was really 3”/less than 2RU. I’ll work on a 1RU solution that protects the screen. Jeff, from my research so far, as you all probably already knew if I am correct, at least some of the other brands like the Lilliput have the same mounting and overall dimensions. Please correct me if I am wrong. I am still researching brands. Someone had mentioned one that is tiltable already, I believe, that I need to find the mention of research.
  8. Thx Ollie. I’ll see what I can do to accommodate these ideas. As for detachable sections, there are several on the market that basically split horizontally/vertically into two sections. Is that what you had in mind or were you thinking of something more specific or different?
  9. Thx Nate. Yes, Rosettes are great for that. Did they come with cart? If not can I ask where you got them and the name/model number?
  10. So I am curious why you didn’t just tilt your cart back on the large, rear wheels when moving outside on a cracked footpath. Was it that the handle(s) on the cart was(were) not at a comfort table height/angle to do so?
  11. That won’t be a problem with my carts or accessories. Designed not to break but if they do, parts are replaceable at the smallest of levels and obsolescence of the carts overall is out because of the extreme customizability of the designs... Obsolescence Made Obsolete™
  12. literally slide into just 1 rack space? or would more be ok, like 3 or 4RU (if including room for say the Speakeasy speaker RU or a patch bay? It presume it could course slide into the back rackmount behind other, short-depth rack mount gear. Reason for deeper frame include better protection for from and or back of monitor and or attaching accessories.
  13. Nate, Thx for feedback. Forgive me if I ask a stupid question as I am more a videocamera guy than a location audio guy. Would it be best if I provide the option of a small patch panel, possibly quick releasable, directly on my proposed tiltable frame for the Blackmagic Smartview Duo rackmount monitor? The Rastorder type cart design you mention requires everything be removed from the shelves to fold it up, so you are right, my carts design type is not leaning that way at this point. That seems to me to be an unnecessary requirement for a vertical cart, and though thinner when folded, it also becomes much longer and their small casters don’t quick release, do they? Is having to remove all the gear something That bothers you? It also is a very fragile design sure to get bent when folded if you ever check it as baggage, even if stored in their expensive soft bag. BTW, i have read other comments on this forum where people say they want very large front casters on the front of their cart, like 5-8”. I don’t understand why since if using the cart outside on unlevel and bumpy ground, where I presume they feel the need for the larger caster wheels, they would have plenty of room to tilt back the vertical cart to its huge rear wheels and move it like a two wheeled hand truck. Have you regretted that your Rastorder cart does not have bulkier, heavier 5 or 8” front casters?
  14. That listing is no longer available.
  15. Any suggestions for Similar popular support monitors? I am designing vertical Location Sound Mixer carts for resale and want to make it easy to attach the most common monitors. I thought this was a popular model but if there are others I would love to know the model/brand names so I can get the dimensions
