After the shops stopped selling planks in a short length, thought how to make a wheel with spokes, with enough sides that it's almost round. Almost round, calculus tells us, a circle can be constructed of many straight lines, so sixteen will be enough, Could make it with 32, cuts, but 16 is enough.
Barrow wheel maths.
Could make it with six, but eight looks better.
Can have square or round spokes.
No difficult hub to make or buy ahead of time.
Simular triangles means the saw cut is 22.5- on my mitre saw, this is marked, must be a common angle.
Another way of working out the setting for the mitre. Will add a diagram later.
180-45= 135 degrees.
135/2= 67.5.
90-67.5=22.5degrees.
Rather than resetting the mitre saw for each cut, leave it, and flip the wood over each time.
After they are cut, adjust the saw to 90, and using the angle just cut, can knock off the edge.
Another view, intending some wheels for this plant stand as well.
Six sided, no hubs.
The first pic, without the lines. This wheel barrow was made directly from the pallet, the pallets support slates have been incorporated into the structure.
Will add a picture, but for now, see the bottom of the wheelbarrow maths pic above.
Here are the eight sections on the flat surface. I find a flat surface is good for getting the segments flat. Notice in the pic, holes for the round spokes.
With the corner knocked off. I'll post a pic how to do this accurately with a mitre saw.
All in a row, with holes drilled to accommodate the screw head.
In Australia, for some reason it's cheaper to buy a rake for the spoke wood at $2.99/rake/1.80m rather than 25mm diameter dowel at $18 a 1.80m length.
The first spoke goes in, from one side all the way to the other. This makes it all so much easier. Like solving simultaneous equations, one solution is already found.
This avoids having an array of spokes going all over the place in the centre later on.
A booklet helps to get things level. Holes are drilled in on the outside, and long screws used.
Holes were drilled with screws used to hold the outer segments together.
With no hobs, drill though the first spoke. Add the hub to one side, and drill again, this picture is of the final, spoke. A drill press is here, but a hole could be drilled with just a hand held drill. Wouldn't be as accurate as this. Note the bearers under the wheel, to keep it square. I could upload a video to show how true the wheel spins. (I didn't bother about a wheel balance. Not being used for high speeds.)
Here is the first hole.
Spoked wheel in the sunset, with an axle.
Could file, or sand down the corners, but doesn't matter.
Picture of square spokes.
Close up.
Can make them with tree branches as well.
