Topic tags/keywords: tack trunk lid support question

Good morning all. I recently completed a tack trunk for my daughter’s equestrian supplies but I need to add a support to keep the lid from accidentally falling on her fingers. I installed a soft-down lid support from Rockler after these pictures were taken but I guess the lid (which holds storage) is too heavy, as it accomplished nothing. I’m now considering using a hydraulic strut from an auto trunk, but have no idea how to determine the mounting position. I need the lid to be able to open more than 90*, and due to the design I can only use one strut on the left side. I would greatly appreciate it if anyone can give me specific information or resources to accomplish this.

The lid measures 24” x 40” and is 3-1/2” deep, mounted on a piano hinge. I’m guessing it weighs about 20 lbs(?).

-- I've yet to find a nice piece of wood I couldn't mess up.

To determine the appropriate strength for the lid support, there are calculators that can calculate that.
Just google it and I am sure that you will have something show up.
Using the correct strength holder will make the lid operate properly and worth the effort.

Maybe a tiny person with a flashlight can mount it inside. Ever try those hinges that are spring loaded. I see you have a latch so any tension it has wouldn’t matter that much. You just want to keep it from falling.

Have your say...
