@@miked9736 I'm going to hinge the top so it can also be used as a shade/rain cover for a small seating area I'm attaching to the front. Food truck style. Good luck with your project.
Oscar: I contacted Dunn & Watson in Au. They sell struts in Au. The video they put out had all the math . Before I placed an order I asked them them to check my math. They refused, { lost a sale}, Your explanation is far easier to grasp. I would however ask that you include the following. To convert Newtons to pounds, 1 N= 0.224809 My door weight is 75 kgs. 43" High. 30 % is 28.66" 20% is 21 1/2 ". I need a strut that will lift. 0.224809 X 750= 168.06, or 169 pounds. Your video will make Life Easier for many people. Thanks.
Thank you for your positive feedback, I am glad you like it. If your used to pounds it makes sense if you convert it that way, but for my understanding is it easier from kg to N ( your door is 75kg = 750 N ) Cheers
@@oscaroverlander_MB1222AF Hopefully we can do coffee this spring. I need your advice- to many questions ,this is not the place. I will email in about 6 weeks. Yes, my door is that weight. The rear taper of my truck will be a storage area. The back pivots up. Al plate is 176 kgs.

Great video. The original strut on my kitchen cabinet was too long and overpowered. I just got a properly-sized and properly-loaded pair for $5 on Amazon. The larger ones were 2x-3x the price!
now now thank you very much for such a Genius video, after saying this video, I have resolved so many issues that I had faced during the production. Still, I have one request, Will you please upload a video where we can use a gas strut from inside the object it will help me a lot thank you.
Glad to hear that, thanks for commenting. Yes I will show my skylight and Panorama hatch from the inside if fully installed in my habitat of my Expedition truck. Watch out for the upcoming videos !
Absolutely Brilliant Oscar. Thank you very much for your tuition This was doing my head in trying to work out how to install it Grateful for your help Cheers Stevo Australia ? Is it possible to fit the struts on the external frame of the door & wall of cabinet. Thanks Damm, well that didn't work, only closes 1/2 way 🤦♂ 🤷♂
@@oscaroverlander_MB1222AF What have I done wrong , the door will only close halfway. The maths is right. 100 n strut, door weighs 3.3kg 600 w door = strut length 325 Position fitted to door 120mm Fitted to external frame work in opened position on door & cabinet because there is nothing to attach to internally. It will only close half way. Got me stuffed
Well you just have to set back the Gas strut brackets on the corpus, deeper in to the cabinet. If your cabinet is not deep enough than use shorter struts. Thank you !
Super helpfull. Question I have is that I have a door 48" x 48" but only weighs 15lbs. How would I determine what to use as it is really hard to find a Gas Strut that is long but low lbs.
excellent video, question though, let's say I would install it for a vertical lid, imagine a chest box.. would all the same rules apply? 1/5 to 1/3 from hinge etc?
Thank you. I’m replacing existing struts that no longer work on my RV storage doors. Hoping to utilize existing measurements. Do the struts need to be “gassed up” to work or should they work right out of the shipping box?
I'm trying to put this on a bed to lift the mattress up so it's basically what you have built here but just flips the other direction. All of the instructions I'm seeing online the lower part is to go closer to the hinge, so would the 20-30% still apply just on the base instead of on the mattress part that's opening? If that makes sense.. I'm wondering do I just do it backwards because it's lifting the other direction, Maybe the rollover that you mentioned at the end..? I'm having the hardest time trying to figure out how to get this on
Well I have never installed an actuator but I could imaging, that weight and lift height the most important parameter are to select the right actuator.
That was excellent! I want to install a swing-up laundry table. When determining the force of the strut, how do you account for any objects that may place on the table?
You can do it! Well now you know how to calculate the force of your gas strut to bring and hold up your table top. But any object on top of the table can be calculated by adding the weight to the table top weight. But !!! This could be dangerous because when you add a basket with wet cloth for example. That would make the gas strut so powerful that the table top flips up with a extreme speed and force ! So someone could get hurt. I would not recommend doing such thing ! Cheers
Great video Oscar, thank you very much. I just wanted to ask, if the weight of the cabinet door is say, 10Kg which would be 100 newtons... would you buy 2 gas struts at 50 newtons each because the weight is divided in 2 OR does it not work like that?
In this case I would buy two struts with 100 Nm and if I like it open softer or stronger I play with the 20-30% spacing, but don't divide the force by two, you end up with two weak struts. Hope this helps Cheers
Should be the same principle if the struts are attached on the sites. If they are attached at the head center point you need a lot shorter but stronger strut. But the weight of the for steps stair is an important factor to find the right struts.
Fantastic video! Be question: if I do install 2 struts will I need 1/2 the Newton per strut? Given that two will add up to the same amount? Like if I need 60 Newton total, but install two struts, do I purchase 2 struts of 30 Newtons?
Great video easy to understand, however I need to put struts on a murphy bed hinged on edge but dropping down then folding up to close. How is this different?
Thank you and sorry I don't have the time to get in to your specific project but this will probably help you. www.gasspringsshop.com/gas-strut-for-murphy-bed/
My lid overhangs. So when calculating the length, do you want the total length of the lid (overhanging) or just the length of the chest itself (excluding the additional overhang of the lid)?
@@oscaroverlander_MB1222AF Thank you! I really appreciate the replies. I struggled for a while and wound up ordering like 15 different sets of struts. It was frustrating not being able to try these in my hands before ordering. The ones that seemed "long enough" online ultimately put too much pressure (like 60#), and would either hang or I couldn't close the lid. Wound up using 14" Vepagoo struts at 24# weight (ordered on Amazon). Here's my project, if you're interested: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6mGPstTkR-c.html
Hi. I want to have a flat screen tv flip down from ceiling. When not in use, stored in horizontal position up close to ceiling. When in use, down vertical. So thinking two struts, spanning from ceiling down to supports on each side of the TV. Any thoughts on which struts to use, and how to configure? Thanks
Well first of all don't mount struts directly to any type of electrical devices it would be extremely dangerous ! I trust that you are not thinking of doing so. If you mount the TV to a board as a substrate and attach the struts and hinge to that it will be fine. Same method here length of the board height and weight of the substrate plus TV . But honestly those ceiling mounts exist and don't cost much ready done and easy to install amzn.to/4cXkqDJ
Can you tell me anything about electric actuators? They dont come in the same length/weight as gas struts. So do i need to know the length requirement or the weight requirement?
Well I have never installed an actuator but I could imaging, that weight and lift height the most important parameter are to select the right actuator.
It matters the cylinder should be up at all times for two reasons. 1. In the cylinder is a little bit of oil which lubricates the seal around the piston, if the seal is not lubricated because the oil is on the other end of the cylinder ( if you mount them upside down ) than the wear and tear is higher and the life expectancy of the strut is degrading pretty quick. 2. If the strut piston extends all the way at the very end the little bit of oil need to be pushed away which has a dampening effect. Means the strut does not run hard against the cylinder bottom almost like a soft closer. Therefore the cylinder should always pointing up !
@@oscaroverlander_MB1222AF Perfect, thank you for replying. I have re-watched your video and ordered the part I need with confidence - thank you so much, my mum should be able to get into her baking cupboard now :)
Good question ! If the door is in horizontal position when closed, than you could place a scale between frame and door leaf to weigh it. Put the scale on the frame rest the door on the scale and it gives you a close idea about the weight, If the door is in vertical position when closed, in this case I would open the door 90 degree place a stool/box under it and the scale on top of the box and than rest the door on it. Just my two cents I do not know what is applicable in your case but there is always a way to find out the weight maybe not absolute but close. Cheers
Both need to be the same, do the math on the force and use two with the same force don't divide the force by two. You are ending up with struts they are too weak to push up the weight.
Well I didn't really skip it but the second attachment point should be with no compression close to the front edge of the object, if this makes sense to you. Cheers
