G-Spot Captain. Last edited: Jul 30, One thing I would change on future builds is galvanized wheels not chrome Had chrome in the past and it was amazing how fast the chrome fails. It is amazing how much different the cost of these trailers is from one coat to the other I bought my trailer built basically as you spec yours with galvanized wheels, and a complete spare including hub with bearings in case of need. Rocket Trailers actually anodizes the aluminum which adds an extra element of protection.
I paid about what it cost you to build. Of course I bought mine in Florida and needed to in order to transport my boat across country, but similar trailers on the west coast are much more Supply and demand I guess. A few factors on my costs: 1 My figure includes sale tax.
I did pretty well, but I know there is a bit to save. I assume trailer builders habe their own forming equipment. I am willing to walk anyone who wants to attempt this through the process. If you need a trailer and have a weekend or two to spare, this is the way to go. Reactions: Kamehameha , Matthew WA and starbright Chtucker said:. Reactions: Gooch Larue , Hannibal and Chtucker.

Apr 19, Kitsap www. Nice project Howard. I've been wishin' I had something like that to bring boats from the local marinas to my bottom painting shop.
Most owners of 28'' boats don't have trailers so they are forced to haul-out at yards that have travel-lifts. If I want that business I'm gonna have to come up with something along the lines of your build.
Tower Todd Number 2. Boat ' Long Range. Nicely done! Omakase said:. Gooch Larue Member. Stair Guy said:. View attachment Definitely on the tongue scale.. First I need the truck. I would rather walk than drive a Ford Bad personal experience I won't be buying a diesel.
It turned out pretty sweet, could use a bit of polish around the edges to make it look more finished, but there is no doubt that it has the right parts. I did get a lot of help Planning took much more time than the actual build. I have had a few requests to start building them as a business. If you want some help, loading it on the trailer and adjusting it before your new truck showes up I can help.
I'm just down the road from you,as long as you don't mind a Ford pulling it out of the water. Remember Me? Advanced Search. Page 1 of 2 1 2 Last Jump to page: Results 1 to 20 of How to Stop Aluminum Trailer from Floating. I have an aluminum I-beam dual axle trailer, and it floats. This is a PITA when loading the boat, what's the best way to stop?
I was backing a friends trailer in the water for him last year and I thought that something was submerged under water on the ramp whne the trailer went up on one side only. I got out to look and nothing.
So acked back in and it did the same thing. Then I pulled out and went to the next ramp over and it did it again. My buddy laughed and told me it was floating. I had heard of that but never experienced it before so I know exactly what you are dealing with. After doing some research I found this to be very common and there only seems to be two fixes.
Some add lead and some steel. I like option 2 best. Good luck. This floating would make getting a stepped boat off the trailer a PITA. My aluminum had dual storage boxes. It would be nice on some of our South Jersey ramps that drop of all of a sudden. I've seen many axles lost trying to pull the trailer out. You have to pick the back of the trailer up while someone pulls it out. Be easy if the trailer floated. Also, choices of Aluminum versus Steel. So, which trailer frame material geometry is best?
The needs of your circumstances should drive the material picks. Hopefully we can also point out something new along the way. Aluminum vs Steel Part 1 , then the following Comparison Part 2 , are both good reading with a lot of detail.
Also, the Article on Beam Shape is great background for selecting trailer frame material. Honestly, the beam shape article and this one began as one article that got too long. You can think of this article as the application of beam shapes � with an eye toward trailers. In general, there are three types of beam loading: Bending, Sheer and Torque. To understand them, here are some quick illustrations. Bending is the big one we think about for main beams Cost Of Aluminum Boat Trailer Jack running front to back on the trailer frame.
Also for cross members going side to side under the cargo. Examples of Shear Forces include areas where the suspension attaches, or where the tongue intersects the front cross member. While Torque loads are not as prevalent in most trailer frames, the effect is still there in some degree.
Twisting often is the result of something attached to a frame member and hanging off to the side. A side mount tongue jack for instance. Or when the loading is bias to one corner of the bed.
Interestingly, it is rare that the above loading conditions exist in just one pure form. Usually there are degrees of 2 or all 3 in a beam.
Take for example the main beams. There is the obvious bending load, then sheer present in part from the bending, and in part from the cross members that attach to it.
Also the suspension loading, tongue attachment, etc.. Then, there is Torque load on the trailer frame material because of the cross members and outriggers if it has them. True, the primary loading is bending, and normally Torque loading is small, but just know that all is not as simple as it first seems. To do the calculations, there are free resources online. One is at engineeringtoolbox.
Start with general calculations, then hone in on the areas that need more attention. Different portions of the trailer frame have different needs, and that obviously drives part of the decision about trailer frame material.
This illustration will work for the discussion, though keep in mind that every frame is a little different. We will refer back to the beam shapes described in the previous article for most of the below discussion. They are usually the longest beams on the trailer and hold effectively all the weight.
Their need for strength is high, then depending on length and trailer type, stiffness also comes into play. Look in the beam shapes chart for those with good vertical strength per weight. Incidentally, these are 28 Aluminum Boat Trailer New often the heaviest pieces in the trailer frame material, but they are not usually the biggest contributor to weight.
Another common requirement of main beams is the connection with other systems. They usually connect the other load carrying elements � like the cross members, the tongue, and the axle s. Technically the springs. The prevalent load for main beams is bending, which is illustrated in this colorful analysis image.
The distribution of color shows the highest stress is on the very top and bottom of the beam. See the arrows. In this colorful image you can also the the little zigs in the stress which indicate changes in the shear forces.
For shorter-ish trailers, C-Channel and Rectangular Tube are common. Some considerations are ease of connection with other beams, interface with the deck, and painting to avoid corrosion. Tube is great to work with as the full rectangle cross section is easy to fit attaching pieces like cross members. Some people like Channel because you can bolt directly through it without squishing it � unlike tube.
Either can be a good choice, and much depends on how and where the trailer will operate. For longer trailers, I-Beam becomes the shape of choice � particularly tall, narrow flange beams.
Cross members are not as long as main beams, nor do they each carry the full cargo load. Typically, cross members span the width of the trailer to support the decking and share the load carrying duties. Wider trailers generally require stronger cross members. Open section beams like L-Angle or C-Channel work well for cross members because they are easier to bolt through.
Simply drill a hole through one wall, then use a nut and bolt. When attaching the decking with bolts, these shapes work well. The open sections are also easy to protect from corrosion paint completely. When choosing material, consider the loads it will carry. For something like a tractor hauler, the load is applied to the deck in just a few locations, so each cross member must be stronger.
However, when hauling rocks or boxes the load spreads much more, and each cross member shares the load. Your choice of trailer frame material for cross members depends a lot on the intended loading, and the width of the trailer. The special case of the first and last cross members is unique � bed front, or the back one called the bumper depending. Anyway, the cross members connecting the perimeter of the bed usually carry greater load, and therefore, have significance. The front member transfers a lot of the bed load to the tongue.
The back member often acts as a bumper, but also carries the load of nearly everything that comes onto the trailer. Ramps and other loading rely on the back cross member.
