Posted by Flyin6:
OK, I have some totally inflamatory stuff to post up. Wierd how my brain works, but you all know I am now writing my second book which spans the innerspace between biography, musings, philosophy, and who knows what. Anywho, for some wierd reason (I hope there aren't any psychologists reading this!) I actually wake up early in the morning with something swimming around in my head, which I immediately write down to capture. Well, not immediately, first I put on that pot of Java, then start writing. I don't know what is going to pop up, or why, I just write it down. Normally I can have up to 5-7 pages of stuff that just comes pouring out and I write until the hunger pains begin, or lack of coffee wain until the need for sweet tea later on. Does all that make sense? For your sake, I sincerely hope not!
Well, anyway my CIEMR this morning is as follows:
I woke up with this definition of what I believe a Liberal to be all clumped together in the gray matter...Lord help me!

Liberal: A person who is committed to an idea or concept despite logic, common sense, history, evidence, or proof to the contrary. A person who is so convinced of the correctness of their position that they demand others change their views, beliefs, convictions, and way of life to comply. Finds accommodation with all beliefs and ways of life despite how farfetched they may be, and demands the 99% change their views to accept this skewed position through the constant creation of laws, regulation, policy or procedure. One who is not satisfied with the natural order of things and believes more control is inevitably necessary for happiness, although a true liberal is never happy, cannot achieve happiness, and has become embittered and hate filled because of their constant failure to change the natural order of things. People who mostly believe there is no God, that somehow randomness and human intellect has produced the world as we know it and willingly accepts utterly fantastic explanations for how things came to be. Someone who does not love freedom and through their zeal to control things in a manner consistent with their beliefs, actually destroys it and becomes its enemy. Lacking of real courage but totally convinced that because of their zeal and ability to argue their point that somehow they display courageous characteristics. A person whose beliefs are generally only found to be acceptable to like minded people and fringe elements of society. Seldom seen on a battlefield or other places where real courage and self sacrifice are required. Willing to benefit and prosper from the labors of others without having a negative effect on their own conscience. Believing that despite how successful some people have become through their personal labor, sacrifice, and brilliance, that the fruits of all that effort should be shared by everyone. A fan of the grasshopper, and truly believes the ant was treated fairly and perhaps even shown leniency
......BTW...No offense to any liberals who might read this, I have to admit to actually knowing some of you, and fondly looking forward to our bantering back and forth!

Thanks!

I just picked up the fiberglass, tight weave which I will soon use.
Here's how that top will come to completion:
1. Next I will build the hinge system
2. Then run the wiring and mount interior and exterior LED lights.
3. Do some sanding, countouring, shaping and body filler work.
4. Cover the exterior with the heavy and tight weave fiberglass mat and resin
5. Fill interior spaces with structural and fire retardant foam
6. Install interior panel, switches, and assundry items such as a inside roof cargo net
7. Build interior ribbing for lower half of the enclosure
8. Finish the wiring and connect
9. apply foam insulation
10. apply aircraft flame retardant carpet
11. Paint upper extending lid assembly
12. Apply vinyl digital camo to lower half and upper edges, vehicle roof and hood
13. Mount topper to vehicle
14. Attach the fabric material to the two upper sections and work out the bugs on that
15. Invade Iran...oops, I meant persuade uncle stan to let me check it out on the farm!

Day 8 of project chop top.
I wanted to be able to erect the top to it's full upright position by COB today, but the construction of the hinge mechanism is a bit more involved than I first estimated.
I decided to wrap the strongest part of the new roof frame with steel which was bonded, screwed and through bolted in place. THe creation of the hinge brackets took me the whole afternoon. but I'm ready to go on the lifting mechanism tomorrow.
To build the aft hinge attachment point, I started with a 3/16" thick 1.5 square tube. I cut it to length, then using a plasma torch, cut one side off forming a U-channel

First I got some news from Road Armor. They experienced some difficulties building our new rear bumper. They moved locations and there was a loss of information on the hard drive, specifically this new bumper design. That is apparently cleared up and the gentleman at Road Armor has the design completed. He said he will do prints over the weekend and send that to the shop for actual construction. shouldn't be too long.
Here's two sketches of it he just sent me showing the back up sensor holes

Posted by Flyin6: (all previous posts by myself or Overwatch are from Flyin6, other than quoted posts)

I have been researching pneumatic cylinders, which is my first go to idea to raise the top. Apparently very easy to construct, and even can be made out of 2" PVC! The working pressures of those things are low enough for them to be very safe, but durable???
I think I am looking at a redesign of the project since I don't have room for full length cylinders.
I have 21" of debth in the bed. I have another 21" of topper height, so 42" total to work with. I need 8" length inside the cylinder for piston, stop and things like that, so I have 34" of stroke available. The top extends 42" so that does not compute.

I will need to:

1. Redesign the hinges to raise the top to a lower height
2. Build a compound cylinder with dual/triple rams that telescope from inside each other
3. Redesign the topper into a hard shell camper unit
4. Abandon this project and purchase some sturdy slide in camper unit like an Alaskan or similiar.

I don't make big moves quickly or without lots of good information (One of Sun Tsu's principles) so I am thinking this thing through at the moment.
Meanwhile, I think I'll press forward with other projects, focusing initially on the suspension and trying to get some movement out of the guy who is supposed to be designing a custom digi-camo vinyl wrap for the truck

Thinking about that top, I think I could get away with two lift cylinders considering the top won't go anywhere with the linkage holding it more or less in place. If you think about it, about half of the cabin area will be taken up by a flat sheet which will be used to sleep on, so having the cylinder/pole there just might not matter all that much or interfere with movement.
Anyway, that's the direction I am thinking at the moment. Next step would be to build a telescoping cylinder with two rams, one inside the other...

I decided to fab up those telecsoping air cylinders just to see if it could be done and to have something to work with to see if I can integrate it into the top.
For those of you who are waiting for "Normal" kinds of modifications, those are all coming, some are even in the mail as I write this, but I need to press on with the project chop top just to see if this thing is going to materialize or get chucked.
Reading about how some folks make cheap air cylinders out of PVC, I decided to see what I could do. THe max pressure on that stuff is 280psi which is a bunch and a lot more than I will ever need so I moved ahead.
Needing a more compact size because the interior is already cramped, I went with a 3" cylinder that telescopes with a 2" ram, then another 1.5" ram telescopes out of that. The purpose is to keep it compact, but get the long reach I want.
Here's the three cylinders/rams

I read about some guys building haloween props. That gave me the idea. The double ram is new, or at least I haven't found an example of it, although I'm sure someone out there has tried it
I'll know tomorrow if that is going to even be a possibility.

I've been playing with the lift scissors design.
I'm going to scrap my first design and start fresh with a simpler mechanism. No matter what I come up with it will probably never be easy to just lift the top to the full up position. There just isn't room for bulky lift mechanisms and a bunch of cylinders.
I may use the cylinder I created because the darned thing works great! Maybe (and I'm not sure about it at the moment) I will use that cylinder to raise just one end. That will make it easier to manually press the other end to the open position.
The top is getting heavier all the time. Ashley was kind enough to send me yet another solar panel, a larger one. Now I will be competing with the Hover Dam as far as power output! I will mount that sucker up there, the gel coat the outside, fill the inside up with foam, install lights and an interior finish panel. I'll easily have the whole top section minus the tent fabric up to around 150 pounds. I guess it will provide incentive to keep lifting weights!
That's it for now. I am also carefully considering option #2 which is to purchase something like a used Palmino Bronco collapsing camper and just mod that thing into my mobile survival habitat.
We'll see...

N2BRK gave me an idea...And you thought the only thing that came from Jersey was great pizza!
I have now constructed two seperate lift systems and by themselves, I don't like either one...
So my apologies for all the build pics of engineering experiments that were just, well, experiments
Maybe I'll go back and have John clean up the thread, or maybe just leave the stuff there to show the evolution.
Anyway the New Jersey connection gave me the idea to go back and review the gear options, which led me to review the cable lift systems and that's when the light bulb came on.
By using a simple hand crank winch some cable and pulleys and two steel lift jacks, one piece of square tube inside a piece of C-Channel, mounted to a pivot on the lower frame, and to a swivel or pivot hard point on the top will allow me to keep the scissors linkage and allow me to crank the top up.
I thought I could mount the winch inside of the top and allow the hand crank axle to poke through to the outside, say at one of the back corners. Then, all I would have to do would be to walk up to the back of the topper, attach the hand crank or even a powerful drill/driver and raise the top while standing on the outside. Then climb up inside and extend the scissors linkage to their over center/locked upright position and voila' (that's french) I'd be living in shangri-la (no idea what language that is!)
So, I'm off on a buying frenzy...gotta get a winch, cable, pulleys, turn buckles, steel, and kitchen sink parts...
CYA soon!

Note from Big Don:  Ken and Overwatch09 have posted all this up so far. Had I done it, I would have left this part out, but I guess it shows some design and progression toward the current end state of that truck...

I'll take that as a your blessing.....so here we go:


Brother Ash...
Here's a couple pics of both of those solar panels you sent me.
The first was a 55 watt unit and the second unit is a 65 watt panel. THat means I will be able to generate up to 120 watts on a sunny day to help recharge/feed batteries which in turn will operate the coffee or sweet tea maker!
Yippee!
