You got it. Hydraulic door...... I have an antec1200 v3 and have been working on it. Im working on the door plan and that is about the only major part still needing the details worked out before continuing. Heres my issue. I am making the door open via triple hinges on the top of the door. The panel will be held down by a spring latch and i want it on a hydraulic push bar but i cant find any on the inter weeb that are small enough. It would likely need to be a 5-8 lb bar and approximately 1.5 ft long(length can be planned around and as narrow as possible). (that is pressure needed to close). Any links to sites that i could find this sort of item would be awesome. Alternatives to hydraulic are acceptable (such as spring pushed) Any other ideas are welcome to ofcourse.
Try searching for gas springs This was the top result for "gas springs cananda" Canadaian Gas springs
Wicked, i suppose that's a prime e.g. of "asking the right question" from Google. I however had someone point out off forums that anything with oil/hydraulic any other liquid may cause a problem as it will eventually break and possibly leak said liquids on my p.c. ...... I gotta say that, for some dumb reason, I hadn't already considered this. For that reason I'll be going gas spring..... Hmm i need an old broken cruddy office chair
ok so i found a crud chair with a gas spring in it.... i nearly put my full weight on it to push it down...... quickly realised that wont do. it would take atleast 100lb of pressure to close the case. Does anyone know if its easy to change the pressure of such things or another common place item that would take considerably less pressure to compress the gas spring from so i can salvage parts. I'm big on salvaging if the parts are just right or have very minimal mods to make them so. For this one I'm starting to think i will need to specially buy the item online somewhere.
Probably better off just buying a new set of gas springs I don't think that they are "to expensive" Plus in doing that you would be able to send the company dimensions and weight, this way you can get a perfect match for your application and have someone to fall back on for replacements if it doesn't work
I havent read your thread, and I am new here. But I am a hydraulic Engineer, and i just wanted to say that hydraulics are useless for your project. You need pneumatics. That is why you cant find small enough hydraulics. Hydraulics are for when high force is needed. The bad point about hydraulics is the use of oil. inevitably you get leaks over time and Hyd oil is horrible stuff. This is why air is used for low force applications. Easier to install, maintain and no oil leaks. Also air is free xD
editor 22 : ya i think ill be doing just that. guth : i am aware of the hydraulic issue and have already stated I opted out of hydraulics for both of those reasons. Thanks for the info thought. on another note ill be posting a physical mod of the HDD bays of my antec 1200v3 by the end of the day. Hope it goes well.
Have a look at my build "Al-13 Duplicity" I have used a gas/spring strut rated at 50 Newtons to open a panel door, I tried another strut rated at 30 Newtons but it was just too weak to open the door cleanly, you can see from the video how the 50N unit works. I was initially a bit disappointed because I wanted the door to open slowly all the way but it opens quite quickly at first (the spring pushing) and the damping comes in near the end of the stroke but now I am glad it does this because if it damped over the whole stroke of the strut you would be waiting a while for the door to open fully I bought it on ebay UK from a company that sells stuff for caravans and camper vans, apparently these units are often fitted to cupboard doors in these vehicles, I also bought a strut from Strutsdirect.co.uk they have a big selection and you can mix and match the end fixings.
Yeah sorry, I just posted quickly and didn't have time to read the whole thread. I'm glad you have opted out of using hydraulics. Good luck with the project. Pneumatics are the same principles as hydraulics so if you need any help then I'd be glad to help. I have been a hydraulic engineer since I left school. (6 years now)
well snapPP That is exactly the application method i intend. Nice rig btw. Now how hard do u find it to close? is it stiff ? does it almost go down by itself when you push it down?
It's easy to close the leverage of the door acting on the strut means just one finger is needed and if you play around with the positioning of the strut you can get it to go over centre as it closes so it's then pushing the door shut which is how mine works, as it gets near to closed it snaps shut. I hope your not disappointed and think that someone has stolen your idea as I know for sure that I am not the first person to do it either but the way I look at it is that it will be unique to my build as it will be unique to your build
"I hope your not disappointed " Not dissapointed at all. If someone else came up with a round object that makes dragging stones across the ground at the same time as another person that just confirms how awesome an idea it is
what about nipping to the scrap yard and grabbing a car electric window motor/setup? cheap as chips and easy to work with?
