Wow! I love this kind of stuff.

Strength testing might need to be destructive in order to find the maximum force the spider can handle.

Or non-destructively you could make a rig and load it with maximum conceivable force plus a safety factor. Then if it survives it survives and you know it's good.

Great work, I have been thinking about getting a spider made for my RS2 cranks which would take wolf tooth camo rings for some time. Unfortunately I know nothing about CNC machines.

That's super cool. Totally get the "I want to do it myself idea" over buying a spider. I guess spiders and chainrings are a very reasonable starting point to get into it. Would love to see more explorations in the future!

Are you saying what I think you’re saying...

Batman in reply to @Oddo

Chainrings are definitely a much more complex part, although I imagine there is far more documentation on how to make them. I run a narrow/wide ring which I imagine would be quite interesting. If it breaks I will fix it!

Confused, and a little aroused

This comment resonates with me. Awesome project!

just saw that SRAM have done some generatively designed crank arms - made me think of this thread.

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
