Cheap(er) Plug in Cart for Hobie Outback

I made a similar one as Insayn, but it was the Saturday afternon before my departure for a trip where I needed a cart.  I did not have time to go get the Schedule 80 so I made mine out of leftover electrical conduit I had laying around from a kayak rack I had made and welded the parts together. The axle is 1" gas pipe that was part of a 6 foot bar clamp.  I had plenty of long clamps and was in a hurry so I cut about 3 feet off.  I made some washers out of HDPE (self lubricating plastic) on my CNC machine and collars were 3D printed to hold the wheels on and so they would not rub on the cart frame. It works great, but is a little heavy.  I will make a permanent one like Insayn's sometime in the future. I believe his design and choice of materials is the best way to go, especially for someone with limited access to tools. 

printed collars - outer collars are printed with a #10-24 thread for stainless machine screws.

Finished product has so far held up to nearly a mile of soft sugar sand (better than I have). 


Also, Wobbler makes carts from copper pipe.  He made me one several years ago and it is still going strong. It only had an axle long enough for Harbor Freight wheels though which is why I made mine out of the emt conduit.

Your cheating.... with the fancy 3D printer..... I’m telling!!!   

All,

Thanks so much for the feedback. INSAYN's idea of the SCH80 PVC is a great one. Both of my breaks in the SCH40 model have been at the tee. The idea of passing the pipes straight through is genius. This will reinforce the joint and distribute the bending moment throughout the vertical pipe instead of concentrating it all into the glued joint. Can you tell I'm an engineer?

I'll buy the parts and reuse what didn't get thrown away from the 1.0 SCH 40 version and post some photos... might be a week or two.

Thanks to all!

Engineers drive trains..... aren’t you the crazy train engineer?

You're wrong.  Engineers are the last ones up against the wall come the revolution.  They want us around to keep the lights on.

Your cheating.... with the fancy 3D printer..... I’m telling!!!   

My 3D printer is not that fancy, they are relatively cheap these days.  I am about to go print out new hinges for my Coleman cooler since all three failed on me this last camping trip.  Those thin plastic hinges they use are garbage.  I would say, every tool I have purchased has paid for itself with repairs it has made.  Well, except for my CNC mill I built, but that was a hobby that took about a year during which I learned a ton about electronics and CAD and CAM. It kept me out of trouble though. 

Also, without a 3D printer how can you print out a scale model of a face hugger and illustrate the progression of disease?
