My '64 Overlander Adventure

[GreatPumpkin]

Sorry, I guess I should have read the question better

Definitely unscientific in my measurements (I used a bathroom scale), but the upright arms weigh about 15lbs each. It takes one bracket at the top and one bracket at the bottom of each upright/arm. The cross piece the arms attach to is almost 30lbs.

I'm sure there is some mathematical equation that says when the awning is extended that the weight each bracket supports changes, but I wouldn't even know where to begin on figuring that out

Picture to help explain?

Great Pumpkin, Sounds like Till has the resources and knowledge to remake the part you need. I have a suggestion after seeing where your parts broke. If the screws will still fit with the modification I'm making, They won't look too different. Just a thought.

That is just what I need to know and see. Thanks!

I have searched my garage, and don't have any extras of the parts you need. Hopefully Tedd's solution will work.

OK, sorry about the delay. I should have a PDF to post for approval this evening. Modeling shows a 12X safety factor with 100 lbs load.

OK so it didn't take as long as I thought...

Let me know what you think.

Almost - I guess I should have used a less ambiguous term than “shaft”. I was referring to a shaft in the male sense, as in a driveshaft, vs your rendering shows a shaft in the female sense, as in a mineshaft. The shaft slides into the upright arm of the awning at the top and bottom.

Looking at your rendering, and referring to the 4 drawings, I’ll call the top left #1, top right #2, bottom left #3, and bottom right #4.

Drawing #1
o The first hole from the left should be centered at .50 from the edge instead of .55 (the .875 between the holes is correct)
o The overall width is currently 1.125 instead of 1.5 (although wider width will work)
o If changing the overall width to 1.125, then the .75 measurement would be .5625 instead

Drawing #3
o The 2.5 measurement should be 2.75. The remainder of the overall length of 4.25 should be the male shaft. It is 1.5 in length, with a thickness of .781

To make, making the part easier, I am going to press a pin in the hole that you pointed out.

I tried (working with the pictures and engineer) to come up with a compromise that would work out best.
Drawing #1 I can move the holes down the .050 if you need.
Drawing #2 The length differeance is due to the angle. To make a angle that is easier to machine the length changed. The over all should still be the same. i.e. from the bottom mounting hole to the top where the pin will be inserted.

Also, the material will be 6061 aluminum with the machined surfaces left as machined. The pin I am not sure about just yet. I am thinking brass or maybe just some aluminum rod turned to the right diameter.

Does this help clear up your findings??

I think that clears it up, except the overall length? Currently the 4.25 length includes the shaft (or pin). If you machine it as pictured, then insert a pin that would increase the overall length by 1.5? Which would then require mounting the brackets further away on the airstream. That would put the top bracket further up the curve of the airstream body, changing the angle at which it sits. Or am I missing something?

I see the error now. My bad, I should have cross checked the picture to the print. I will get it revised drawing with the over all length (minus pin) set to 2.750 inches. Should be interesting to see what comes of this little mistake.

OK lets try this again. The pin will be aluminum. Press fit then welded at the bottom (by where you will rivet it in place)

[GreatPumpkin]

Till, that looks great.

The drawing is in the shop and scheduled for a production run of four pieces. I will get a e.t.a. in a couple of days and then I'll PM you about the shipping side of things.
