Camera backpack cart.
Sep 2, 2018 15:14:40 #
I put this together out of stuff laying around the garage (except for the wheels).
Nothing fancy, an old milk crate that I cut about 1/3 off of, mounted wheels and handle to the 2/3 part.
I will probably paint it all black if it proves to be useful.
I wanted to be able to take two systems, macro & birding, without carrying all on my back.

This side opens to the camera compartment with various deviders.
I use the waist belt to hold the pack in the crate.
Hard to see but there are three elastic cords with balls that attach the pack at each corner of the crate and attach the pack handle to the crate handle.

Rick, Clever construction. Sense is that plastic handle will snap. I would consider using metal conduit pipe sending it and put foam insulation on the top part.I put this together out of stuff laying around the garage (except for the wheels).

The handle is 3/4 schedule 40 PVC (thicker wall than the usual schedule 20), pretty tough stuff.
I have not tested the rig with any weight in the backpack yet, just finished it this morning.
I will find out if the plastic holds up when I load it up.
Conduit would add a lot of weight.

I loaded the backpack with 15 pounds & rolled around in various conditions and the
PVC handle barely flexed at all so I think it is good to go for a real field test.

Great invention, now if the handle was collapsible that would make it Really great!!

PVC — especially the schedule 40 stuff — is quite tough.

If it snaps, skip the big box store and find an industrial piping distributor. Ask for sch. 80 or if they have it sch. 160 if available.
Since you are not using for piping system your good to go. Or go to 1”. more torsional strength. Tidbit, on piping products the outside diameter remains the same while the inside diameter is reduced to provide the required wall thickness.

The handle is removable by pulling one pin at the bottom and sliding it up through the bracket at top.
I wanted to make it easy to get in my car.

Having passed the first test, I will paint the PVC black so it isn't so gaudy

Clever! Are you going to use it as travel driving or on a plane.
I mainly plan to use it for extended (1/2 day or more) visits to the larger parks around Houston.
I wanted to get the weigh of caring systems (macro and birding) off my back.

One thing that would concern me:
Other than on absolutely smooth surfaces, rolling along the backpack will cause an enormous amount vibration to the contents. All that constant vibration to camera and lenses cannot be good, as these contain many delicate mechanical parts which are easily knocked out of alignment. As you are planning to use this setup for birding, I assume you will want to take it outdoors where the surface is surely to be rougher than the smooth kitchen floor you have at home.
I suggest attaching larger wheels to the backpack, as this should at least reduce the amount of vibration.

I expect to replace the small wheels but didn't want to spend the money until I found out if the concept would work.
I also plan to isolate the pack from the crate with a layer of closed cell foam.
