I intend to paint my bike and the rack at some point, however I wold like to leave the wood it's natural color. I'm looking for paint ideas that would go well with the natural cedar look. Give me some tips in the comments if you have any.
Pro Tip: Listen to jazz while you work!
Step 1: Design Goals, Materials, and Tools
-build it myself
-square bucket pannier compatible
-flat bar(many sizes will work)
-1"x2" wood of your choice(I used cedar)
-all thread or round bar around 1/4"
-4 or 6 nuts and bolts to mount the rack
-2 or four nuts and bolts to attach the supports and rack together
-6 nuts to mount the wood planks
-nuts, washers, or spacers to separate the wood planks and align them on the all
thread or rod(there are 12 spots that need something)
I've omitted some amounts here as they will change depending on your bike and personal design.
-angle grinder or file
-drill or drill press
-a die(to thread the round bar if you choose it over all thread)
Step 2: Design
This is basically just the outline of the rack's platform. You can see the two tabs on one end where it will mount to the bike.
This view shows the supports that will hold the platform over the tire and where these supports mount. near the bottom of the photo you can see two dots. These dots represent mounting holes that are intended for a disc brake caliper. I skipped the longer support when I found that the rack was really strong with just the vertical support.
Step 3: Bending the Platform Frame
1. Measure and mark where the first bend should be.
2. Clamp the material in the vise so that the longer portion of the material sticks straight up in the air.
3. Square the material to the vice so that it is perpendicular to the top of the jaws of the vice for a straight bend. This is important!
5. Repeat for the other bends.
How to bend.
1. Place your hand on the material about 10 inches above the vice. You did leave the long end on top right?
2. Push the material with your hand to the point that the steel feels like it is about to bend(don't actually bend it yet!)
3. Grab the hammer in your other hand and strike the steel where it goes into the vice.
Your bar should bend sharply when you've got it right. Simply pushing the steel over with your hands will yield a bend with a large radius. Simply hitting it with a hammer will probably take a long time. Using both works well because your hand will be putting most of the necessary bending force on the material and the hammer will put the additional necessary force right where you want the bend.
If you bend something too far(more than 90 degrees) simply leave it in the vice and gently pull the material back with your hands. It should bend back easily. The steel will "want" to bend back towards its original shape for a while.
You can see the rack ended up wider than planned. This happened because the jaws of the vice were taller than 1-3/8" so those bends ended up longer than planned. I simply made them as short as possible and adjusted on the other end to match.
Step 4: Mount the Rack Platform and Cut Supports
Step 5: Mount Supports and Attach Them to the Platform
By now you can definitely see what your rack is going to look like. It's a good time to make sure you're happy with all the work you've done so far as you're mostly done with the load bearing portion of the rack.
If everything is bolted on tight you can put some weight on the rack and see how it reacts. I was able to put enough weight on the very back that front end of the bike came off the ground. It took a lot of weight for this, and the rack felt sturdy under the weight. I would be comfortable with a person riding on this rack so long as they're not too big.
I should mention that my bike did not have gears when I mounted the supports. After I got the gears back on the mounting bolt interfered with gear changes. I now have to get bolts that will fit the thread in the holes. This so far has been a pain though I haven't made it to the bike shop yet. Please comment if you know what size bolt I need. I've found some that are the right size, but the thread seems wrong.
Step 6: Adding the Wooden Platform
Three boards are what fit best for me. You may have to trim yours down to get three in. Cut them to length(about 15" for me)
My idea here is simply to get three boards and drill three holes in each so a piece of all thread or rod can slide through to support them.
You can see how there will be a gap between the wood and frame. This will allow for pannier hooks later.
1.Cut the boards
2.Sand them smooth and round off the edges and corners
3.Line the boards up and mark them to be drilled
4.Drill the holes in the boards. Be sure to
4.Cut three pieces of all thread the width of the platform frame(I left mine a little long for now)
-Leave a nut on both sides of the cut. you can use them to fix the threads that will get messed up when you cut the all thread.
5.Slide the boards and spacers onto the all thread how ever you want them
-This is when spacers or washers are better than just nuts. It takes forever to thread the nuts all the way down.
6.If you've used nuts as spacers adjust them so that everything is straight and doesn't move
7.Set the platform on the platform frame and mark where holes should be drilled
8.Punch and drill the marked holes in the platform frame
9.Install the platform into the frame and secure it with lock nuts
10.Trim any excess all thread off so it looks nice and is no longer a hazard
Step 7: Finish It Up!
I think I've pretty much met all of the design goals. I'm pretty happy with everything except my mom promptly called it cute when she saw it :-/
I plan to add a milk crate and a small tool box soon. I'll post some pics when I get around to it.
