SuiteSuccess Posted February 13, 2018 Report Share Posted February 13, 2018 Below is a picture of my “Big Boy” ramps. I store them under the smart when traveling. I would like to put some HDPE strips on the supports in between the “fluted” bars to keep the metal from rubbing on my deck. I need to drill some 3/16” holes in the box supports to rivet the strips on. My question is am I going to induce a stress point that is prone to crack in the future? To my thinking the side walls of the box frame carry the stress and my holes would be in the floor, but I’m not an engineer. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

Darryl&Rita Posted February 13, 2018 Report Share Posted February 13, 2018 Epoxy won't stick to HDPE. I don't know of anything on the market that will be a permanent fix, but some epoxies will last for a while. In a case like this, I'd get the HDPE heat formed to a "U" shape, and epoxy on all 3 sides. I have been wrong before, I'll probably be wrong again. 2000 Kenworth T 2000 w/N-14 and 10 speed Gen1 Autoshift, deck built by Star Fabrication 2006 smart fourtwo cdi cabriolet 2007 32.5' Fleetwood QuantumPlease e-mail us here.

Moresmoke Posted February 13, 2018 Report Share Posted February 13, 2018 The top and bottom of the box have the most stress on them. The stress on the sides is minimal. If you think of how an I beam is made, the center webs purpose is to keep the top and bottom flange the right distance apart. I would avoid drilling holes in the ramps if possible.

Jack Mayer Posted February 14, 2018 Report Share Posted February 14, 2018 My experience with HDPE is that nothing will chemically bond it other than to itself with heat welding. You have to mechanically attach it. I've used various epoxies and none have held for long. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

hone eagle Posted February 14, 2018 Report Share Posted February 14, 2018 West systems makes a epoxy that will glue a poly kayak ,that was cut in two. After bonding they ran down a gravel pile with it. Back to full strength. might work bet it fixes coolant tanks too, least long enough to get home. 2005 volvo 670 freedomline singledNewmar Torrey Pine 34rskswoot woot Link to comment Share on other sites More sharing options...

ALLOY Posted February 14, 2018 Report Share Posted February 14, 2018 VHB (very high bond) tape may stick to the HDPE. Shorter strips of HDPE is better as it needs room to expand and contract Can a strip of (black) HDPE be bolted to the side of the steel deck and another block to the end of the ramp that would slide across the deck? Gluing is HDPE is possible but it needs to be flame treated. Finding a glue that will bond alum to HDPE maybe an issue. 2011 Cameo 34SB3 Link to comment Share on other sites More sharing options...
crazybanshee Posted February 14, 2018 Report Share Posted February 14, 2018 I mounted some 1 1/2" aluminum angle on the bed surface from side to side and slide the ramps on them. Saves the bed and gives a secure mounting for the ramps 2007 Volvo 780 Ultrashift Trailersaver Hitch 2017 Momentum 397th 3 Yamaha Banshees 2 Honda 400EX's Polaris Outlaw 50 Polaris Outlaw 110 EFi 2018 Polaris RZR S 1000 Stealth Black 2019 Polaris RZR S 1000 Titanium Matte Metal 2015 Polaris RZR S 900 VooDoo Blue https://i.imgur.com/e0ajU8Pl.jpg Link to comment Share on other sites More sharing options...
rickeieio Posted February 14, 2018 Report Share Posted February 14, 2018 Carl, use heavy duty zip ties. If the hdpe is thick enough, whittle a recess so the tie doesn't rub the bed.
