well i got a few questions (hope you can answer)
first do you plan to sell these looks like a great idea
2nd do you have a plate or something designed yet to make it a 23 foot instead (extend the deck over the toung)

I値l try!

Not on your life, too much work! Not enough money in it.

Still thinking on that one, kind of a design as I go! Not sure if I want to box in that area with C-channel and use plywood, 2 x6, or expanded metal. I will use C-channel as a brace from the inside padeye, (front of trailer) to right beside the 2 5/16-inch ball right beside the tongue. Most likely I値l weld some angle iron to the web of the 8-inch x 15-pound wide flange beam used for the base. Somewhat of a triangle.
The uprights are 12-inch x 15-pound wide flange.

are you doing anything to compensate for the addtional stress appplied to the hitch and frame that is caused by the longer moment arm of the gooseneck?
I have seen several trailers with this type of conversion and all had far to much deflection to be a safe design. I would imagine that the structure of the trailer would need to be beefed up for this conversion to work safely. Or that the gooseneck adapter would have to be tied back in to the frame farther

I believe a lot of the weight is taken away from the tongue! I believe the weak link will be the 20-inches of unsupported, (span between gussets and the 1-inch bolts) 8-inch x 15-pound W-shape used for the base. The shortest span my book gives is 3-feet, which point loaded is good for 28,000-pounds times two, which = 56,000-pounds. The next weakest link is the four 1-inch grade 8 bolts, two on each side. Now remember the shear for one grade 8 bolt is 71,500-pounds.
Rest assured I致e had numerous civil engineering friends look at the one in the first picture; none of them would even take the time to run the numbers. In fact just last summer a mutual engineer friend borrowed that trailer in the 1st picture to haul 7-tons of hay, he was quite impressed with how well it towed, again he would not take the time to run the numbers!
The 1st adapter was made with 6-inch x 12.5-pound S-shapes. The one I知 building now has 8-inch x 15-pound W-shapes for the base, and the verticals, and horizontals, (not pictured) are 12-inch x 15-pound W-shapes! The gussets are 1/4-inch plate 24-inches horizontal, and 30-inches vertically, with 4-inch x 1/4-inch flatbar welded to them.
The trailer in the 1st picture has been on the road for 3 or 4-years, if I remember correctly.

I just asked my buddy the other day what his weighed, he was going to try and find the weight slip, but seem to remember 1,100-pounds. I値l weigh mine when it痴 all said and done. He well be here tomorrow to help set the horizontals. I値l post more pictures in the next couple days.

well could you have your friends do us up some plans

I would be very careful about selling those..... if something happens, someone gets hurt then you're going to get sued. I'm not saying that it's a bad idea or design, just protect yourself, set up a LLC or something like that.

When I first got talked into building his I bought a set of trailer plans from Northern Tool for building a 12,000-pound gooseneck trailer. Total waste of money! All you need is to right click each pictures, save as! When doing your material list take your own measurements from your trailer. The horizontal beams that extend over the truck bed are 8-feet long, cut them at 5-feet, put a 15ｰ angle cut on the 5-foot section and the 3-foot section for a combined angle of 30ｰ. Once that is complete turn the two beams upside down place side by side, end to end, and level horizontal to the world. Take a 48-inch level and plumb a vertical line at the end of the 3-foot section where your gooseneck receiver will weld.
Now you know all the important measurements to building these, any 4th grader can do it!

Here is a progress report:
Didn稚 get a whole lot done this afternoon, got the horizontal beams set, and tacked. Tacked the Bull Dog receiver in place.
The reason for the section of staging off to the right; used it as a batter board. Used a string line from the back of the trailer over the top of centerline of the bumper pull receiver. Tomorrow I値l have to place some welds in the proper place to pull the A-frame 3/16 of an inch back in line with the center of the trailer. If that doesn稚 work I値l break out the O/A torch and do a little heat shrinking http://img.photobucket.com/albums/v512/Chyrel/H1.jpg http://img.photobucket.com/albums/v512/Chyrel/H2.jpg http://img.photobucket.com/albums/v512/Chyrel/H3.jpg

Thats quite heavy! it looks well (over)built. Nice work.
In the picture of your friends trailer it sure looks like the frame has bent up just like most I have seen. I am sure most of your engineer friends will not do the calcs becuase your component is well more than you need, but at the same time it DOES increase the stress and leaverage on original ball mount A-frame. But again many trailers are far overbuilt, and this may not cause any issues so long as you stay within the original design weight and loads of the trailer.
Think about attaching another board to a teeter-toter, would there not be more stress across pivot point? Same as adding a cheater bar to wratchet, it adds more toque to the socket, while also creating additonal stresses in the original wratchet handle.
As usual, outstanding work! Wish I were there to lend a hand and pick up some tips.
Thanks, come on over, I知 always willing to pass on what little knowledge I have!

Thank you!
I built bridges for a living. I知 a fanatic about welding gussets, bracing, strong backs, or what ever it takes to produce a solid / safe product. For about 10-years I was a supervior over weldors, me not having an education, (but knowing the work) I was always assigned an engineer to work for me. Now I知 not talking a licensed engineer just a kid right out of engineering school, (cheaper). I learned a lot from these kids! But not a one of them would teach me how to calculate stresses / loads of beams. They would calc anything I asked, but would not pass on that tid bit of information!
