Box bracing?

It was 7 cubes before the bracing and 6.96 after? I did some math and I don't think it will be a problem with the tuning.

There's no way you added MDF bracing and only took up .04 cubes...

Ohhhhh I read that wrong, I though you meant you calculated the new volume added to be 6.96cft.

I agree, re check your numbers because so far you're telling us you only added 9.6"x9.6" piece of MDF if the thickness is 3/4".

Do the math again, retake the class, or read more on adequate bracing.

Well you figure it out then! 25 x .75 x 3.5, is exactly how much mdf was used.

That little bit can hardly count.. specs/pics of the box?

liquid nails =/= bracing

I use wood glue. Works for me. And id recommend threaded rod if your worried about space.

Liquid nails sucks. I can break a liquid nails box apart so easily.

I built my whole new box out of Liquid Nails, and alot of it was used in my van too. Stuff is crazy strong. It will break the wood before the joint breaks.

The woodglue is ok, but doesnt seem as strong as the Liquid Nails, IMO. And the Titebond, and all other woodglue is so runny. Makes a total mess. The Liquid Nails is thick and comes out in a nice bead and doesnt run.

Well thee a different liquid nails there is just a wood a panneling a heavy duty I use the HD and many times tearing boxes apart broke wood before nail but they are also glued and other stuff on inside

On my boxes I use screws and tite bond 2 for the bond. Then liquid nail along the crevace just for that not goin anywhere feelin. I use to use l n only but i like the tite bond better yea it's runny but man strong as hell. Just do screws also get a counter sink bit and then if painting the box just cover the hole with bondo. Oh and bracing I use all thread looks mehh but man strong and does not affect internal space much at all.

The first one I built was 9.8 cu. ft. This one is 7 cu. ft. The first one was flexing like crazy and that's why I added braces to the second one. I used the triangular mdf braces. I might be able to knock a few of them out with a hammer, but that liquid nails is strong as hell?

Liquid nails has no use in anything related to actual wood working. Wood glue is all you should be using. There is actually chemistry behind the difference, so unless you want to hear a treatise on bond types, then just trust me that by saving money and going with wood glue, you're actually getting the strongest bonding substance for wood.

I dont care what science is behind it, if the Liquid Nails is as strong/stronger and 10000x easier to work with, Im using it.

i parked a 9600lb service truck on 2 small 3 cf boxes made with LN Projects tubes and it stayed that way for 3 months.

what do you think they use on houses for the subfloors and sheathing?
