Correct if this is not in the right place.

Since I ran out of abrasive chop saw wheels, I moved on to another project.

I hope to try some steelhead fishing in the Snake next week and don't really want to pull my homemade camping trailer or put on my camper I thought that I'd upgraded my camping in the back of my pickup canopy.

I have some bent PVC conduit lying around from an abandoned other project that didn't work out to my liking. The admiral was sore about that but that's behind us now.

I've moved on. I plan to modify 6 of the pieces to make an extension off the back of my pickup. It has to be free standing so I can move the pickup around without making any changes but I don't intend to drive any long distances with it in place. A few miles maybe but not back and forth to home.

Here is what I have. I built a propane furnace a couple of years ago that I plan to use and have a false wall and door that sit behind the tailgate that I can leave in place when driving down the road. The furnace's exhaust will be disconnected in order to close the tailgate so the furnace will also be turned off. The propane bottle can sit on the tailgate and be fastened to the pickup with a bungee cord or two. I'll cook off the tailgate and leave the tailgate open when camping. The canopy door will be closed when I want it and while I sleep inside. I have a thermostat opposite the furnace on the canopy and hang a smoke/CO detector in the canopy. I need an extension to keep out the wind and rain/snow. When the canopy door is open it funnels water into the back of the pickup. That is unacceptable to me.

I plan to make up a poly tarp for a cover. I've sewn these before with good success. I've even sewn in sippers, velcro and loops that hold well. I prefer a white tarp but a green or silver will do. I'm depending upon the admiral to get one for me. The tarp will be held up over some PVC hoops fastened to EMT conduit and supported on my home built hitch carrier. I'll provide pictures as it progresses. Many of the parts are already built. I'm hoping some of the techniques I use will spark some further ideas you may use in you projects.

I made this framework to bend the PVC for the original project.


Here is one of the old PVC pieces placed over the framework to show how it was used.

The side pieces still need to be cut off and the center connecters will be modified with longer connectors because they are too short on that end.
This shows the PVC cut to length on a temporary jig to bend the end around the 3/4" EMT conduit stub fastened to the side of the 2 X 12. Next is to heat the PVC end to bend it around the EMT.
Here is my heating method. I can't overstress the issue that in order to heat the PVC it needs to be at least 4" above the flame and kept moving. Since these pieces are already bent it is more difficult to rotate them but that must be done. Failure to do so makes them look like marshmallows.
The end is bent around the EMT in this picture. Note, I didn't burn it.
All the ends are bent. Now to use the same piece of EMT to bend the new center sections. That picture did not upload to Photobucket. I'll get that later.
This picture shows the new center section temporarily in place on one hoop. There will be 3 such hoops.

The outside PVC conduit is 1 1/4" and the inside is 1". Those sizes fit together well so I choose them. The two side EMT conduits are held from separating by the rack fastening at the pickup and one at the other end. These EMT spreaders will keep the PVC from spreading out under load. At the pickup they will rotate up and down while the other end will be solid. The EMT is 3/4" and it slips into 1" schedule 40 iron pipe (non galvenized), There is some welding here. I make my own wing bolts using 1/4 - 20 X 1/2" bolts with 1/4" or so rod welded across the not.

I use a piece of copper tubing flattened on one end to hold the bolt. There is less arcing this way because it makes a good connection and protects the threads.



This shows a bolt in the copper tubing with a rod on top.



My homemade holder in place to hold the rod for welding

These wing bolts have been sprayed with cold galvanizing from Rustoleum.

Now I need to get back to work. The paint has been drying next to the stove.

I added a lot of pictures and pushed the wrong button loosing all the input. I'll try again this time adding more posts so I won't loose so much.

Here is the center PVC piece in the form where I cooled it to keep it's new shape.



To heat it I simply held the center over the flame 4" to 6" and rotated it back and forth about 3/4 of a turn.

Here are the wing bolts sprayed with cold galvanized paint (Rustoleum)



Painted and watching it dry (actually went in to eat lunch).

After lunch I brought out the pickup and attached the home made hitch carrier.



Then the steps.



Note that the steps have a rise of 7" each.



The steps folded up ready for travel.

Now the canopy rack. I only made the attachment points for one bar, in the back to attach tarps etc.



Note there is a hole in the half piece of conduit. It is used to index the matching conduit to keep it from moving when I fasten it with a modified hose clamp.



Notice that the hose clamp has a washer welded into the screw slot to make it easier to attach without any tools.



This picture of the other side shows it better.



My old (new to me) $100 canopy on my new pickup. I had to raise it a little in order to get it to clear the tailgate. The new pickups have a rounded on the outside tailgate so I had to raise it. I used 1 X 4 boards and thinned them down a little leaving a small lip all the way around to let water drip off keeping the water from running in. The top got the normal sealer and the bottom, nothing since I take it off often to use the camper. So far no leaks.

Tomorrow I have to figure out how to attach a couple of 1" conduit pieces to the sides of the carrier that will accept a length of 3/4" conduit that will support 2 vertical pieces of 3/4" conduit. I have the 1" conduits already built from a previous work with 2 set bolts in each. I have also made the end for the 3/4" conduit that will accept the vertical one. The issue is how to attach the 1" pieces to the carrier without getting in the way of existing tie down loops.

I usually come up with something over night. Goodnight!

More progress today although kind of slow. I came up with a way to attach the conduit to the rack.



Driver's side



Passenger side



Framework is attached to the pickup. Now for fitting and sewing the poly tarp.

Today I spent the day fitting the tarp and sewing it. I cut it shorter and sewed in a loop that I slid in the rope. 4 grommets were installed to bring the rope out and back through. A couple of 1/2" PVC pieces of conduit were cut and ripped, heated and bent into hooks to clip under the rear fenders. These were attached to the rope on each side. I also sewed some velcro to the tarp in places to attach to the EMT conduit. There are also some loops of rope I sewed to the tarp to use for tying to existing grommets.

At the end of the day I put the pickup back into the garage and put on the tarp cover. I believe it'll work OK. My trial will be Monday afternoon when I go down to the Snake for some steelhead fishing.

I'll take some pictures tomorrow when I put the false wall in the back and install the furnace. The furnace I made is a heat exchanger type that draws less than 1/2 amp when running. That's why I get away using the vehicle batteries to power it. The muffin fan that blows the heated air inside draws 1/4 amp and there is no combustion fan. You can see the pipe on back of the canopy where I attach the metal dryer duct between the furnace and it. It is open at both the top and bottom to reduce the affects of wind. A pilot light in the furnace shuts off the propane if it goes out. So far, no CO or propane detected by the detector.

That's it for today.

Do you plan on leaving the extension on when driving down the road or will you take some parts off and strap it to the roof?

I plan to take it off and stuff the pieces in back for now. Usually I sew up a bag to put them in but some of these are a little big for that as they are bent. That'll be a future process as this is my second attempt. I've always said that I liked my 3rd build the best because by that time I've worked out the kinks. It takes some use to see little enhancements to build in that are not easily added.

Today I'll post pictures of the cover on the framework and my sleeping bed inside along with the false door and heater.

If there is interest in another topic, I am considering showing some propane heaters and stoves I've built and how I built them. I also have some additional information about working with electrical PVC for non electrical projects. I use the same heating techniques for electrical work. Let me know if you are interested in such other projects not directly boat related.

I'll pass on other projects. I don't have much use for alternative heaters in southern Louisiana. Just hit 73 degrees here and have all the windows open. :D

I've finished the project so now it is just for the field test. The forecast is 100% rain tomorrow and 90% on Tuesday along with windy conditions so I guess it should be a good test. If I have problems I can always bail.

These pictures are of the poly cover on the extension. I'll remove the cover and framework for the drive down and reassemble when I get to the river. There's no sense in adding additional wear and tear to the poly material driving 50 - 60 mph on the back roads that I travel.







I'll close by giving a report when I return.

Here's the report from my test. The weather was warmer (in the 40's and 50's with lots of rain and strong winds. Today the winds were expected to be in the 50's or more so I took the hint and left with the gusts.

The framework held up without problem. The poly tarp took a beating and tore loose at the bottom right. I guess it needed better reinforcement than the 9 mil HF tarp material provided. Leaving the bottom extended below the framework allowed it to flap too much so that should probably have been folded back up inside and fastened to make that area thicker. It did stay relatively dry inside and provided a good cover to cook under during a downpour.

The strong wind caused my furnace pilot light to blow out several times so that'll take some more thought.

The fishing was a bust. Even the boaters that braved the weather and whitecaps reported poor fishing. The fishing calendar forecast excellent fishing.

It's always good to get out so I'll say the trip was overall positive. ++++++
