Delrin and thread lock?
 

Just putting together a BWD whip and all of the delrin chassis parts that accept screws are pre tapped and I'm wondering if its safe to use any kind of thread lock or this just a bad idea?

if anything use some CA glue, loctite disintegrates plastic

Re: Delrin and thread lock?
 

As stated regular (as in Loctite) Thread Lock melts some plastics. Tamiya sells a thread lock that is safe for plastics. I've been using it for 25 years with no problems.

heres what the descriptions says.......

This is Thread Locking Compound from Tamiya. Must be used on metal or steel items, not plastic. FEATURES: Color is blue Apply thread lock to the threads before installing. Prevents the screws from working loose,which will happen if it is not used. It is very effective and easy to use. Screws can be loosened or removed for maintenance by using extra pressure.
INCLUDES: One Tube (10cc) of Thread lock
COMMENTS: Do Not use this on plastic, as it will melt the plastic!

Interesting, and I can't find this statement or anything else from Tamiya websites. I'll have to see what it says on my tube, but a Google search shows other people, like myself, have use the Tamiya stuff on plastic without problems.

Look you should have no issues with screws backing out. Delrin is nice in that way.

Delrin should hold well without any locker but if the threads are loose or damaged and you need a better hold, check your local auto parts store for this:

I checked my tube of Tamiya TL and it's all in Japanese :roll: I still swear it's safe, I've used it on many types of plastics and never had a problem.

use nothing, but if you have issues the smallest drop of CA on the threads is perfect in screw into plastic applications.
