Metal thickness for Kayak Rack

admin

Hi everyone, new to the forum here.  I am trying to DIY a similar kayak rack to the attached picture.  I just have questions on how thick of steel should be used for the project?  Any opinions would be welcome.

Reply:Start it a purchased rack.  Then add your kayak accessories.  You will have a variety of steel gauges in you fabrication.  Design will dictate steel.
Reply:You'll need the specific Drawbar stock which is a set thickness and shape---rounded edges so it slides in the receiver correctly.11 gauge (1/8") for  the rack upright. You could use 16g for the  rack frame base where the kayaks sit on.Last edited by Broccoli1; 07-22-2021 at 12:02 PM.Ed Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge

Reply:You could also purchase a cargo carrier and then add the upright attachment to hold the kayaks.https://www.etrailer.com/Hitch-Cargo...ks/HR1485.htmlEd Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
Reply:To OP,  I am sure you thought of this already but just in case I’ll mention it.  I don’t kayak so not aware of typical length.  Remember to keep the total height under 14’ as well as watching where you drive with low over hangs while transporting kayaks in vertical position.  Know your total height by measuring and always Pay close attention to over pass height restriction signs as well as low hanging tree branches.  Ok carry on.Last edited by N2 Welding; 07-22-2021 at 01:48 PM.Lincoln, ESAB, Thermal Dynamics, Victor, Miller, Dewalt, Makita, Kalamzoo.  Hand tools, power tools, welding and cutting tools.

Reply:Thanks for all the quick responses guys, I appreciate it.  The tallest kayak is 12'6", so I think it will be ok.
Reply:Tallest is 12' 6" and most receivers are around 17" off the ground and you think you will be OK? You may want to rethink that.
Reply:If you are not going to be carrying bikes at the same time like in the reference pics then perhaps you can make the rack hold the kayaks in a angled position to make them stand on it from the bottom right corner to the top left corner to reduce the total over all height vs standing them straight up in a vertical position.  That should reduce the total height by about a foot or two. This might also reduce your wind drag.  Don’t forget to keep the total stickout three feet or less from the furthest tail light or what ever the regulations will be in the states you plan on traveling through.  All is good, keep it safe.Last edited by N2 Welding; 07-23-2021 at 01:50 AM.Lincoln, ESAB, Thermal Dynamics, Victor, Miller, Dewalt, Makita, Kalamzoo.  Hand tools, power tools, welding and cutting tools.

Reply:It's going to rest a good 6-8" below the receiver in that cradle, so I think I will be ok.  I will do a mock up to make sure it measures out before I get into it.
Reply:Ok so I'm an idiot, the kayak is a Trophy 126, so I wrongly assumed it was 12'6".  I just checked the Google machine and it's only 10'6".

Reply:Unless you're just doing this for fun I would go with a modified cargo rack as well.Harbor freight has the best prices. I would use this and weld it up instead of using their often questionable hardware:HAUL-MASTER500 lb. Steel Cargo Carriercurrently $63.00https://www.harborfreight.com/500-lb...ier-66983.htmlThey have different models and different metals, but their prices usually can't be beat on cargo carriers.
Reply:Kind of a novel idea, BUT,, you will have to be concerned about overhead clearance, AND, when the rear tires drop into a road divot or when you turn and go up hill,,, all of the tolerances are going to change on the bottom of your rack.  Just saying.  Good luck
Reply:That looks like a fun project and it'll be so useful and worth the effort.  Good luck and I hope you feel like posting pics of the progress.Yeswelder MIG-205DS(3) Angle Grinders at the ReadyJust a hobbyist trying to improve
Reply:I have seen others post pics of the cargo rack setup with milk crates on them to hold the nose and it's just not my style.  I plan on using this setup a long time, and I like the look of the one above.

Reply:a mercedes ?  u shoulda told me u were rich.    i like being around the rich, escpecially when at the  beach/vacation.         i've done  work a couple times for  an old carny, he's got  a big nice motorhome same color as ur's, w/ a cat motor in it.     i dont know what kind it is, but its fancy/pretty/tinted windows, looks like something a rock band would tour in.  he's got a hitch that isnt even extended out as much as  ur's, and the slow/right lanes on calif freeways are rough and beat the hell outa it.      i had to beef his up, before he went over the grapevine  towing his cashiers cage or whatever .   he's got a big gouge almost all the way down the side of his pretty motor home, and he's has bad decision maker  when it comes to driving/etc.    hes fat/big nose, dresses in all black like johnny cash, but is a nice guy, and knows how to do biz.   he took all three  inspectors that magnaflux the welds,  out for a long lunch while i fixed the rides, and he pays in cash (all $20 bills), and is nice to his dumb son-inlaw, and rest of his family.      all in all, he's a great guy.Last edited by 123weld; 4 Weeks Ago at 03:25 PM.
