|Threading [message #31099] Mon, 18 July 2011 17:57 UTC
I have an assembly with four holes that need to be threaded in order for me to assemble it properly.
- 3/8-16" Hole for a shoulder bolt
- NPT 1/8" or 1/4" hole at the end of a peg for a pneumatic tubing insert
- 10-24 through hole for a pneumatic cylinder rod
- 7/16-20 through hole for a pneumatic cylinder mounting nut
After having a suction cup printed out of WSF i'm reasonably certain I can can make threads fine enough for the 3/8-16 hole with the model directly.
How would you suggest i make these threads? Another thread suggested that i should take a look at threading inserts. McMaster-Carr carries a wide range of options and Im having a hard time selecting the correct option and accounting for material flex and stress.
It would be significantly easier if I could directly tap the material, does any one have experience doing this? Im planing on making all of these pieces out of WSF or ALUMIDE.
