motorcycle trailer build

Assemble the frame day.  (Before Easter) I carried the frame rails, the tongue, axle and cross members out of the basement, stacked them on the recycle bin while I dug out the saw horses and enhanced their stability and size.  They're the fold up bracket type that have lived outside much of their life, and they must be 10-12 years old.  I used scrap wood/plywood to make stringers to keep them from wobbling, and some of those have rotted away, it's clearly time to remake them.

But not today.  I got down a couple of barn boards that I had used to build 2 different entertainment centers, one in 1989 and one in 1993.  I used some screws to fasten the boards to the 2x4 that is the top of the saw horse so they would be long enough and wide enough to put all the parts on for assembly.

I laid out the frame rails and cross members and began bolting them together.  One thing I hate about metric bolts is that the bolt head and nut are often different sizes.  In this case, the bolt heads are 16mm and the nuts are 17mm.  This is good if you only have one set of wrenches, I guess.

I then bolted on the spring brackets and then addressed the springs.  The trailer is rated for 1070#, but I don't expect to ever load it past 400#, so I removed 2 of the 3 leaf springs, hoping to minimize bounce and it should also lower the trailer a little bit.  It's not too hard to remove those leafs, simply clamp the the springs in the vice, bend the clip that holds the 2 small leaves to the large leaf so they will separate and then unbolt the middle bolt that holds all 3 together.  They don't paint the leaves separately, so the long one is already a little rusty, it's now in the basement with a coat of primer on it.  I'll squirt some black on them before bed.  The spring brackets come silver and not painted at all.  I don't know why.  The spring mounting bolts come with a regular nut and are drilled for a cotter key.  Why not just send nyloc nuts?  

Another way to make the trailer lower is to mount the axle on top of the spring instead of under the spring. It took a while for me to visualize that, and I'll post a pic when I've got that done.  Yeah, never mind all that...because when the axle is on top of the spring there isn't room for the fender.

Had some fun when I was ready to put the wheel on the axle...it wouldn't.  The bearing wouldn't slide on the spindle.  And then when I gave up putting it on, it wouldn't come off.  Wound up ruining the seal, returning/exchanging the axle, and starting over.  4/6  Sadly I did not realize that I had ruined the seal until today, when no replacements were available, so the frame has one wheel on, and one wheel off.

I started on the electrical tonight, first mounting the front marker lights, which ground via the mounting screw.  I may take them back off and add a ground wire for each light.  The wiring harness has just a short wire to ground to the tongue, and I think I want to ground each light.  So I spliced on a wire as long as the other wires before sliding on the wire loom stuff, woven nylon sheath, it's magical stuff.

I will post some pics, I promise.

Motorcycle Trailer build

Since we desire to haul a lot of crap when we go on a vacation, we decided to get a trailer to pull behind my motorcycle.  

A nicer way of phrasing it might be:  since I'm a fat bastard, my clothes take up a lot of space, more than my saddle bags can handle.  Therefore, I need a wagon.

There are lots of them, ready made, ready to go.  They are also very expensive and that's just too easy for me.  Sometimes it sucks being a diy sort of guy, enjoying building stuff is nice, but also exhausting.  

Here's what I'm doing.  I bought a trailer frame from Harbor Freight, got it on sale with a 20% coupon, $177.  It's red except for the rims, which are white.  Our bikes are blue and black, so I've decided to paint the exposed parts of the frame black.  Why not paint all of the frame black?  Lazy.  No, actually I figger if a passing motorist sees a flash of red in the all the black, it maybe the saving aspect.  I've got a can of black paint that was new in the 90's, I used some of it on our repurposed pipe hand rail last summer.


Isn't it cute?  40" wide, 48" long.  You can see that the fenders are black already, too.  I wonder if I'll want a longer tongue, sort of like that guy from Kiss.  No, no not that kind of tongue.

I sanded the red paint with 150 grit aluminum oxide sandpaper.  2/3 of a sheet folded into thirds, only took one side to sand 2 sides of the front and back pieces, 2 sides of the side pieces and 3 sides of the tongue piece.  The axle comes black, but that paint is already scuffed, so I'll sand it and paint it too.  I clean the sanding dust off with a rag soaked with alcohol and will brush  the paint on with a cheap disposable bristley brush.  The paint has been in the garage since 1995, so it'll take a few minutes to warm up, I don't know if I'll get the paint applied tonight or not.  




I plan to tape some paper on top of the table saw and will use some small bits of wood to hold the steel above the paper.  I'll probably apply 2 coats and between coats will put the brush in a plastic sack, wrap it up good, and put it in the freezer.  This keeps the brush usable for both coats without cleaning. 


Sanded and tags taped.  It might have been easier and faster to unrivet them, but we'll never know now, will we?

Why not use a spray can?  Several reasons.  

  1. It's winter, and I don't want to do that much spraying in the house...it goes all over and the furnace would suck some in.
  2. I'd have to buy a couple cans while I already possess this 3/4th gallon of gloss black.  I'll lose more paint to the skin on top of the paint than I'll use on the steel.
  3. I think brushing puts a better coat on the item.  If it were round or intricate, I'd be spraying it
Why wipe the steel with alcohol?  It cleans off the dust, it cleans off any other dirt, oil, grease, wax, other goobers or snot.  Alcohol is cheaper than xylol or lacquer thinner, doesn't leave a film like paint thinner would, and is safer to use in the house than those first couple.  MEK and acetone would also work, but they also stink and are dangerous to use.  Also more expensive.




yep, another coat is in order.  This pic was taken when the paint was very fresh, it'll level out some, but not that much, of course.  It'll be a couple days before I assemble the pieces, but stay tuned for bearings.
