Question on 1/8" thickness for jet ski dolly

admin

Do you guys think 1/8" is adequate enough to hold a 1000lb ski?  I am looking to make my own jet ski dolly so I can save some space in the garage and was debating whether or not to use 1/8" or 3/16" thickness square tubing.  Was planning to use 2x2" square tubing.  I would think 1/8" thickness would be enough as long as I have provide some bracing.Last edited by krouchchocolate; 02-22-2015 at 04:52 AM.
Reply:Being new to welding, I am sorry i cannot help you answer that question. But I have the same concerns. I think I tend to way over build because I am not sure what size steel to use. Short of becoming an engineer, is there a guide or some way to determine what the right size is for a weight and span?
Reply:Does a jet ski really weigh 1000lbs?Even so, I suspect that 2x2 1/8" square tubing will support it fine.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:I would say 1/8 '' is fine. A picture or sketch of the design would help. Like these ?Attachment 1015771                      Attachment 1015781
Reply:I have two waverunners...about 850 lbs.  I use an overhead lift to offload from trailer to my two dollies.  I used 2x2" by 1/8" thick square tube.  I built them similar to the picture in the previous posters (left side) above.  I used 5" castors and made them using regular adjustable bunks just like on a regular boat trailer.  One thing to consider..is height. I made mine so they sit low so I can service the engines without having to climb up on them.  My oil filter is way under the engine...so low was better.You will love being able to service them, clean them ( I wash mine on the dolly)...and role out of the way. Don't use cheap casters..It is sort hard to see...but you can see my dolly in this photo
