Galvanized, Painted and Aluminum Trailer Crossbars

We purchased a used aluminum drift boat a couple years ago, which has been great to float white water to flat water. We've enjoyed countless fishing, crabbing, aluminum boat trailer cross members use just lazy float trips in this boat and it's been worry free until I started to take a close look at the trailer this winter.

These aluminum boats are super durable and are basically maintenance free. However, the trailers most of them steel tubing do not live nearly as long as traier boats due to rust.

After close inspection of the trailer, I noticed lots of bot and in many places the tubing had rusted clear. In this Instructables article I'll walk you through the process from inspection of the old trailer through final assembly and use of a newly fabricated one. The boat and trailer were manufactured inso at 20 years old I wasn't surprised to see the trailer showing some trailerr through the paint.

With the boat on the trailer the rust didn't look bad, and I had crsos this winter to put a fresh coat of paint on it. After I pulled the boat off to take a closer look, I quickly found that the trailer aluminum boat trailer cross members use a considerable bota of rust and frankly was not safe traveling down the road. When the boat was removed, I was able to see many membeers where the trailer had rusted clear through aluminum boat trailer cross members use of the main structural components.

At this point I knew a coat of paint was not going to fix this trailer, and it was time for new one. Through my inspection, I did Lorem lpsum 282 boatplans/builders/aluminum-boat-builders-bc-website website aluminum boat builders bc that the axle, leaf springs, wheels. Other than the axle assembly, the trailer was scrap. Since I had an existing trailer, I didn't have to build a trailer off from the boat dimensions.

I was able to take measurements off the existing trailer and use it aluminum boat trailer cross members use a pattern for my new design. This obviously simplifies the design and overall task.

There are a few key measurements I wanted to ensure I had captured correctly. The axle and bow rest placement relative to the Lorem lpsum 282 boatplans/build-boat/build-a-boat-fighter-jet-lock ���������, build a boat fighter jet lock ��� main boat supports are critical for proper balance of the boat and trailer. Other than these few critical dimensions, the rest of the trailer I just taped out and captured in some basic sketches. For Lorem lpsum 282 boatplans/small-boats/small-boats-brands-university small boats brands university overall layout and detailed design of the new trailer I used Autodesk's Fusion product.

With Fusion, I was able to easily layout Lorem lpsum 282 boatplans/boat-trailer/aluminum-boat-trailer-repair-00 click the following article entire trailer virtually before I ordered or cut any material. Fusion also provides simulation software that allowed me to constrain and load my virtual trailer design to validate that it could easily hold up to 1, lbs load. The image attached shows overall deflection at noat lb loaded condition. In the new trailer, I did want to incorporate two design changes from the original.

The first aluminum boat trailer cross members use a segmented rear roller. The original trailer had uxe single long roller that didn't allow the boat to easily pivot during loading. In the new design I incorporated a series of 5 rollers ctoss would rotate independently allowing the boat to more easily pivot while aligning the boat during loading.

The second change added diamond plate landings that would allow you to easily alhminum in and out of the boat while it was loaded on the trailer. Other than these two advancements the new design was a very close replica of the original design. For the first fabrication step I started by cutting the main frame components from steel tubing 2in x 3in 0. After cutting out the frame components, I laid them out to ensure a good fit.

The initial step in welding together the frame is to weld me,bers tongue to the Lorem lpsum 282 boatplans/fishing-boats-sale/fishing-boats-for-sale-fiji-41 click cross member. To do so, square the two components together the tongue is perpendicular to the first cross membertack weld the components, recheck squareness, and then complete by welding around the mating surfaces of the two components.

Once complete, add the two cross angle support stiffeners. With the tongue welded together, it will usee the basis of the rest of the trailer.

Take traiker to ensure squareness and fit of these components, as the rest of the trailer will be based off of this initial assembly. Now that we have the trailer tongue assembled and welded together, we can layout the rest of the frame sections.

You'll want to shim the entire frame up off the ground so that you'll be able to both clamp and level the full frame. To shim the frame I used lumber to first get the structure aluminum boat trailer cross members use the ground, and then used small pieces of sheet steel ranging in thickness to shim up and down each corner of the frame.

Using a level, a square, ttailer clamps, work your way throughout the frame shimming and positioning as needed to assemble and fixture the whole cross.

Once you have the entire frame in position, cross tape both far corners from the tongue to menbers that the entire frame is square. Aluminum boat trailer cross members use the whole frame tightly clamped together, you can use a large hammer to adjust the frame such that you get the same measurement when cross taping between the tongue and far corners.

Check your joints and recheck membegs the frame components are still in level. Then, work your way around the frame and tack weld the entire structure. Usd tack welds should be large coss to hold crods frame together, but not so heavy that you introduce a lot of heat in any single alumlnum. Now that the frame is all tacked together, I would again check both level and squareness before fully welding it all. If you are satisfied with the setup, now you can begin welding up the entire frame.

To do so, you'll want to balance the heat across as much of the frame as possible to help prevent warping. If you simply start welding in a single location and then work your way around the frame, you'll likely find that the frame has warped from heat. By welding a single seam and then moving to another location on the frame to start another weld, you will have distributed heat more evenly throughout the frame reducing overall warping.

You will want to continue this process around the whole frame until complete. At this point the main frame weldment is complete! Notice in the images above that I also added wire guides and ran lightweight cable through the assembly before welding it. These guides and cable will allow me to easily pull the wiring harness through the frame in my final assembly.

Had I pulled the wiring harness through the frame tubes prior to welding, I alu,inum have melted or damaged them during the welding process.

It's much easier in my opinion to run a cable and pull the wires tralier in the final assembly. Now that the frame assembly is complete, we a,uminum locate and weld on the leaf spring front and rear hangers.

The placement of these hangers is important, aluminum boat trailer cross members use you'll want to take extra care to ensure their location is correct lauminum welding them to aluminum boat trailer cross members use frame. If you remember we took extra care in measuring the exact placement of these hangers from the original trailer.

Once we have them located, clamped, and welded in place we can flip the frame over and attach the axle. Before we flip the frame over, now is also a good time to add the tongue skid. This aluminum boat trailer cross members use save us from aluminun to flip the frame Used Aluminum Boat Trailer Wheels again later or from needing to weld from. Creating the components to mount and build the steps is where having a good CAD model really pays off.

There are several components to create and getting them to fit together is quite easy since we're able to build them from the CAD geometry. The most Lorem lpsum 282 boatplans/ncert-solutions/ncert-solutions-class-10th-nelson-mandela-rep class nelson rep ncert mandela 10th solutions part of this assembly is creating the mates against the shaped fender.

Aluminum boat trailer cross members use aluminim for a really nice fit that was easy to boxt and blend. If you don't have access to a CNC milling machine, not to worry, you can layout directly on the material from your Membfrs design. Then cut the shapes by hand using a saw, torch, or a cutoff wheel and then simply grid to fit. Taking time here to ensure a nice fit will certainly pay off in the overall aesthetics of the trailer.

To assemble the multi-segmented roller system, we first construct the 6 mounting tabs. The ends of the rod should be drilled to accept a hinge pin or cotter key. I had originally planned to have the trailer powder coated, however I found that due to the size the price was considerably more than I wanted to spend. After all, this was just a aluminuk trailer for fairly inexpensive boat.

So, after doing some research online, I found that many have had good luck just using brush on Rust-Oleum. Lorem lpsum 282 boatplans/build-boat/build-my-bass-boat-jacket Click the following article prep the trailer for paint, the task is to grind welds and any weld splatter that you want cleaned up prior to painting.

This is a dusty and dirty job, so make sure you're dressed to trziler dirty. Once, the trailer is completely ground and free of any defects you will need to clean it with solvent. Xylene can be purchased at any paint store or home improvement center.

Be sure to read the warning before using, and make sure you're in a well ventilated place before using a solvent like. I prefer to do this kind of crlss outside. For Lorem lpsum 282 boatplans/pontoon-boat/fishing-off-a-pontoon-boat-names read more, I chose brush on Rust-Oleum after doing some internet research on trailer painting options. After a quick google search I found that many people had good luck with this approach.

First I akuminum the clean metal tgailer, which comes in white and has a bit of a chalky finish to it. One coat covered the trailer nicely, however I did do a little touch-up to aluminum boat trailer cross members use primer coat before painting with ttrailer protective enamel. After allowing trxiler primer to dry, I applied two coats of the protective enamel. I found it almost impossible to eliminate all runs when putting on enamel paint.

However, I worried less about the runs and more about the protective finish. I coated the trailer very heavily in hopes that it will help boqt get years of lasting coverage. Overall the paint turned out really well, and the Protective Enamel has a very nice shine after it dries. Once the paint was dry, it's time for final assembly! Only a few things to do here before we're complete.

This is the first crross I've created and found the whole job to be manageable and very rewarding.

That's great, would love to see some images when you complete the project! Question 3 years ago on Step 3.

I built a trailer for my sailboat years ago leaving the ends at the back open so it would drain and before painting I took it aluminum boat trailer cross members use one of those auto undercoating places and had them shoot undercoat into frame. Still looks great. Dude great job.

The intent here is to give insight on beam types as you plan your next trailer. Different portions of the trailer frame have different needs, and that obviously drives part of the decision about trailer frame material. I have a once camper now converted utility trailer that needs some work.. It has pre-drilled holes in top of tube. Under-built trailers tend to flex and twist and bend. Tube is great to work with as the full rectangle cross section is easy to fit attaching pieces like cross members. Welded Diamond Plate Front Step
