| Making a Spider |
| Well, after searching the internet for spider designs that I could possably build, I came up with this spider. It can be adapted many ways and be made from just about any materials you can get easily. I had to buy a pipe cap, The rest of the parts came from scrap stuff I picked up or had laying around. I think the center hub could be made from hardwood such as a large piece of dowl rod. |
| The First step is to accurately divide and mark the Hub. I used a ruler to divide it into 3 equal sections. This was marked for 3 vanes. It was alot of trial and error but spend the time to get the lines straight |
| The first 3 cuts are at the 3 vane positions The cuts are made with a hacksaw and they are 1/4"deep |
| The second 3 cuts are 1/8" to the right of the first 3 cuts, for all 3 vanes and are 1/4" deep also |
 |
 |
| This is what the hub looks like after the second set of cuts. |
| This is the final set of cuts to the hub. if all goes well, it should look like this . |
 |
| This is how I lay out my vanes. I then cut them out with tinsnips. You will have to figure out what size vanes you need. |
| Here I am drilling the vane pin holes in the hub. I used cut off nails for pins. |
| I drill a 1/4" hole through the hub |
| The last 3 cuts are optional They lighten the spider and alow for easyer pinning of the vanes |
| The ends of the vane are brass 1/4x 1-1/4" bolts with the hex sawed off, then split 1/4"deep with a hacksaw. |
 |
| This is the finished hub with one vane pinned on. It is hard to see but there is a pin in the 1/4" brass bolt also, to hold it to the vane. |
