Hi All, This is my first post. After reading hours of posts on core77, I think this place if full of creative geniuses.
I am looking for a permanent way to hold together a leg between 2 plastic pieces. I want the shaft that goes in the hole to be hollow, cause i plan to pass something through it. I have attached an image with the dimensions.
The leg (center) is aluminum and the plastic parts on either side are delrin. I want the fastner that holds the leg and the plastic together to also help in restrictive rotation (a little bit of torque) so that alittle force is required to rotated the leg about the hollow pivot point (the shaft).
Here are the options i was thinking so far:
- Custom aluminum eyelets (contacted manufacturers and seems like the tooling for this will be expensive, and don’t know if they have enough space to install these, see the image)
- Plastic shaft with one flanged end and the other side with clips or something like a grommet and maybe use O-rings to offer the torque rotation (will the O-rings wear out after a while?)
- Get a thin aluminum tube and flange both ends (not sure what kind of tool we will use or if there is enough space)
Guys please share your thoughts and any ideas? I am open to modify the dimensions if needed and am trying to get a cost effective method thats cheap for mass production.
PS: sorry for the enlarged images
Thanks for all your help in advance.
