Teardrops n Tiny Travel Trailers

I was just wondering as to the weight of a full hatch such as myself and few others have..Mine I think could be 45 - 50 pounds ..

I just want to make sure I go out and get the correct 2 pumps for mine..

Im being careful ... or maybe overly careful as I construct this 2nd hatch..

Ive checked and double checked the squareness of it and Bingo it is.. as the ply sits so nicely to it when dry fitting...

Hey there, Heikki!

There's no easy answer to your question, I don't think! So much depends on how you mount your lid props. I'm only guessing, but most of my Galley Lids are in the 35-55# range, and I use gas props rated at between 45-85# each. If you are getting your props locally, then there shouldn't be any trouble exchanging them if they're not right for you needs. I know things are a little different there in Finland with regarde to parts availability ... do you have a reliable and well-stocked auto parts dealer over there like NAPA, or are you going to have to mail-order those props?

Good Luck, my friend, and as always ...

CHEERS!

my hatch is about 5'x4' made of 1"sq thin wall steel tube , 1/4"luan ,3 layers of fiberglass,and sheet plastic inner. it weighs 35lb and I used 2 100lb struts

Heikki,
Take the hatch off and weigh it with bathroom scales!!!!

Ohhhh - I tried to read the links in your message about struts but can't understand a thing that's written - is it Greek?

The weight of the hatch and the force needed to hold it open are two different things. The weight is a constant once it is built, and the force needed to open is dependent on the mounting point of the struts. The distance of that point from the hinge will "multiply" the force needed due to the leverage of the hatch. The closer you get to the hinge the more force needed but also the higher it will open for a given stroke strut. If you move the attachment point away from the hinge, it will require less force but the same stroke unit will open the hatch less. I used a scale and a stick to measure the force needed every inch for about a foot along the side of the hatch, then determined how much each of those points would open with the available stroke units.
