As a mechanical engineer who loves the water. This is a ********* for me. (get the pun? ;) ) Awesome project.

We test competitors products all the time. It keeps them honest and they do the same with us. Industry says 150% load, then it better hold 150 % load. Arms were setup to worst possible loading setup with highest load. The lift should have held.

In some cases undersizing can mean overspending too.

Just make sure your garage doesnt get really hot, I have seen fire suppression systems go off at gas islands in the summer before on really hot days. Made one hell of a mess for no reason.

You deffinitly need to have an opening for the compressor to draw air in. You would be amazed at just how much air a compressor draws in(scfm). Vent to cool the room would be good to, but just the opening at the top ducted outside with the louvers in the bottom of the door will casue the air to...

Any Updates? Place is looking amazing!

Sure the idea works for the mechanics of it. Its a simple force-moment diagram. But is the hill sturdy enough to hold the load? Or does a retaining wall need to be placed? how much load are you looking to place on the entire storage area; how much of it will be on the overhang? is there erosion...

he added to much....that was the problem....he used a larger re-bar size then called for bc he thought it needed the extra strength....this increased the load on the beam causing it to fail.....not my explanation....that was my roommate again...who is the civil engineer

you quoted me but forgot to quote this part "my basic understanding of engineering says this is bad.....my roommate who is an engineer says this is even worse" notice the last part? AN ENGINEER....said this was a bad idea to attempt as a DIY

any type of cantilever design like this needs serious design work by a professional engineer........think about it this way....ur storage container falls into creek....city or town shows up and wants to know why this happened....u end up in a small boat with a hole in it up ur creek without a...

my roommate who is a civil engineer says get one lol...yes a cantilever is a nice idea...in fact its been done out over the grand canyon concrete will be used to provide the foundation but the design of it with respect to footers and such will need to be done by an engineer

http://xflexsystem.com/default.aspx Blast proof the lower sections, goes on like wallpaper, can stop a mortor round, "wallpaper" then rhino line, then challenge ur buddy to put his fist through the wall

The answer to your question is.....AMPS.....two batteries provide more CCA(cold cranking amps) to give more juice to your starter. this is unless your truck happens to be an old military truck in which case it runs a 24V electric system complete with two alternators and two 12V or one 24V...

Now I am partial to ford....dont mean to stir up a nest here but a Ranger will do just about anything you want it to..my little four cylinder(with 8 spark plugs) has hauled a 1000lb irrigation pump down the road at 70 mph(i didn't know it was 1000lbs at the time until i got to the dump and...

I am still in college and I can already tell I am going for the wrong thing....
