The ones I use are black. Chocks are raised two inches. Roller for ramps (end that I’m pushing under car. One for each ramp and I leave them on while traveling. Height of wheels only about half inch above ramp end). Walmart cutting boards that I set other end of ramp on to keep from rubbing bed. However going to change to rubber “feet” that I will attach to one end. I “X” the straps front and back to center the ramps under the car. Like I said not elegant but it works. Howdy Carl, THANK YOU for the photos. True "elegance" is something SIMPLE that works and your setup is both simple and elegant. I see you use the same "channel" as I do to locate and hold the ramps into position. I am sure that this tread is going to be of great assistance to anyone who is thinking about building a Smart Car deck, I really wish there was a way of having all these build threads placed in an easy to FIND and ACCESS place here in the HDT forum. I doubt I am the only one who has trouble with and is frustrated trying to find information especially photos when using or in my case failing to find such information by way of the search function. That's the main reason I try to give my threads a very descriptive title so I can find them again should I ever need to. Again thanks for your post it is a gold mine of information which I will put to use.

noteven Posted February 9, 2018 Report Share Posted February 9, 2018 Another method is “tape measure engineering”. That’s where when you’re out for a bike ride and see a commercial flatbed hauling something big and ugly with weight outboard and you stop and tape measure the materials in the deck "Are we there yet?" asked no motorcycle rider, ever.

However with the kind advise and support of members of this forum, I will prevail in this endeavor. Once the weather allows me to make sparks I'll return the favor with a detailed photo enhanced build report.

I found a couple that used formulas that are WAY BEYOND my mathematical ability to understand. I "assumed" that in this day of computers there would be a web site where one could for example plug in a description of the steel being used, the span it would cross, or the lenght of span if only supported on one end, input the load and get some kind of table or graph showing if what you wanted to do was safe or give you guidance on what type of steel you would need to do the job safely, I could find nothing like that.

NoDirectionHome Posted February 9, 2018 Report Share Posted February 9, 2018 Quote Is there a web site where one can plug in the type and size of structural iron that would calculate this type of information? I'm sure there must be. Try Engineer's Edge. For tubing some manufacturer's may have a calculator. The difficult part is calculating the moment of inertia of a particular cross section if you want to do it long hand. For instance I had to estimate the corner radii and tensile strength of the steel so all numbers are approximate as indicated.

TXiceman Posted February 12, 2018 Report Share Posted February 12, 2018 Dave, I am a retired mechanical engineer and used the site some. My career was spent in applied heat transfer and thermodynamics, so I did not get into the mechanical side often.

My career was spent in applied heat transfer and thermodynamics, so I did not get into the mechanical side often. Ken Howdy Ken, I have no formal engineering education but spent my life as a machinist, welder, fabricator and was always one to push the envelope in building high performance engines and off road Jeeps. Just kinda did what I felt was right and it always seemed to work sometimes pretty well and to the surprise of others who would later copy what I tried first. When it comes to building the Smart Car, deck I am not trying to reinvent the wheel, I'll be incorporating the ideas of MANY into my build with some touches of my own. I am grateful to ALL who have shared their knowledge in this and all my other threads concerning the transformation of the Peterbilt, into my next RV Hauler.

Howdy Brian, So based on your post and that of others, I will as usual be over engineering this bed and should have no problems carrying the Smart Car as I have in mind to build the rear deck.

mr. cob Posted February 17, 2018 Author Report Share Posted February 17, 2018 Howdy All, Got the commercial hitch taken off today, little steps but I am getting to where I'll be able to start building the bed when the weather improves. I finalized my plan on how to build it, have a quote for the steel, now its just a matter of when I'll be able to start making sparks.
