Builds Troopie build (1 Viewer)

[crushers]

hummm, there is 16" of support on each side and another 12" at the back.
are you suggesting full length support each side?

 

[crushers]

so 44" of foot print (full gutter depth)
20 lbs per square inch is 880 lbs of weight.
i wouldn't want more than 1000 lbs on my roof especially with the COG being so high already.
but
this being said, if i have a concern to consider i want to hear it.

cheers and thanks for the comment and i look forward to discussing this further with you.

Hmmm, is this right? If you have 44" of contact that is 3/8 wide then that is 16.5 sq inches of contact - at 20" per sq in that would be 330 lbs.
Perhaps another way to look at it would be to decide what the gutters can support per linear inch - since all the load is levered off the edge of the roof, the width of the support isn't that important?
Just thinking out loud.

 

[crushers]

yes, you are right. squ inch ...
i have an old 70 series sitting out back, i will start doing some testing next week. i will make up a 1" wide "hook" and start hanging weights off it till it bends. i suspect 300 lbs will not bend the gutter but it will be fun to try.

Wayne,
If you want the roof rack to be stronger you need to place a section that joins the legs together and sits down in the gutter.(basically full length gutter weight distribution). This will help prevent the rust, gutter bending and the turret stress fractures that 75/78 series troopies are renowned for.

From what tourboy said I'm wondering if the gutters on the troopies bend / fracture easier than on the other 70s?

 

[crushers]

if the fractures are from stress then this rack should actually cure that issue as it will also reinforce the structural integrity of the roof line at 11 places...

Yep,
The troopie rack made by ARB here in Oz has this. It helps to keep the very flexible body under control stopping horizontal cracking along the top and bottom of the windscreen and also where the door catches are on the main pillers. This is also where rain water leaks and body squeaks come from.

The 78 series have aditional strenthening plates on the pillars to help with this from the factory, but on mine it just made it crack elsewhere like behind the doors at about the bottom of the window height where the pillar has the kick in it they crack horizontally right thru.

I think that part of the problem with gutter cracking is that people often do the mounts up too tight. If you tension them until you see the gutter start to flex it isn't usually enough to stop them working loose on corrogated roads so must be cranked tighter causing cracking of the drip check sealer, allowing water in rusting etc. The longer mounts actually prevent the rack from moving the poofteenth that works the mounts loose. Does that make sense?

 

[Awl_TEQ]

Just want to interrupt the structural integrity discussion to throw in a "well done" on the aluminum work there


Sooooo -

Well done ​

 

[crushers]

yes, it makes complete sense. i had planned on a rubber foot that goes under the support to prevent rubbing and chaffing. this would allow some flex, after all the weight is down, not up.
snug is good, tight isn't ... at least that was my thinking on the matter.
got pics of the rack in OZ?

thanks Awl, appreciated.

 

[tourboy]

I haven't got any pics of the racks but there should be some in cyberspace somewhere.
I tried to PM you but for some reason it said it was unavailable at this time.

Here is the link for my truck if you haven't already seen it.

If you want anything more specific let me know. Now has a 145 litre propane tank on the
tray as well that the camping box will fit over. That gives me about 2000km between
drinks with the dual petrol tanks.
Cheers

Here is the way ARB puts a bar between the towers
Deluxe steel 1100mm x 1250mm | Products | ARB 4x4 Accessories

Hope this link works!

 

[crushers]

link worked, pic didn't, did a search and i see the bar. that would be easy enough to install. 3/8ths round or flat bar welded to the bottom of the supports to spread out the load more.
i will investigate more next week.

thanks for the link.

 

[crushers]

the frame is back and looking better than new.
the color is growing on me the more i see it.

 

[crushers]

the rear of the side box storage coming along.

there are certain that make me nervous, cutting holes in a perfectly good body is one of them. these are access holes to the rear PTO winch required should anything go ... sideways.

sometimes you have to just stop and look around.

[crushers]

yah, there is quite a bit of storage room being salvaged.
i am now trying to decide which latching to use, i have 9 different latches being delivered on tuesday. i want them to be simple, (inexpensive would be nice since there is 12 lids needing them)((some of them are $55 each, DAMN)), close to flush mount and reliable.
the floor winch access will have removable aluminum panels made with rubber seals between the aluminum and the steel floor.
i am hoping the body will be complete next week so i can move it outside and bring the frame in for reassembly but 2 days are shot so we will see.

i am getting excited to start reassembly.

 

[Phil in BC]

All I can say is Wow. What a nice job Wayne. I wish I had half the skills you do. Two thumbs up on this build!!!!!!

 

[crushers]

thanks for the compliment Phil, appreciate it.

i have met many people over the decades that had skills they never knew they had till they actually tried something. some are worried about failing, the only real failing is to never have tried.

i am fortunate to have the passion, the obsesion, that i have and the people that trust me to do a good job.

Mud is a great location to hang out on, i learn (and share) a lot of information here. i appreciate the brotherhood that has developed because of the site. A huge thanks to Woody is in order (from each one of us) for providing and keeping the site alive.
