X-Belt tensioner Change inserting process
Closed, DuplicatePublic


We have found that using the standard Weller solder iron tip is causing to much plastic to flow back into the insert making it impossible to get a screw in. Quincey has taken an old tip and cut it down so that the tip does not come into contact with the back of the hole which is increasing the amount of plastic to flow back into the threads. She is also following up with a 2 mm driver to make sure there is clearance in the backside of the insert by pushing back any warm plastic that may be preventing the bolt to rest. We would like to have this modified Weller tip and process added to the OHAI moving forward to prevent this problem.

@tomc Lets take a look at this together. With the right temperature and pressure I haven't seen this occur. Come find me when you have a moment

I modified 4 tips today after fixing a batch of x belt tensioner parts which had bloom in the threads.

NOTE: please use the Dremel when performing these modifications, the grind stone is too porous for the soft copper based material these tips are made out of.

I gave 3 to pre-sub and have the last on the soldering iron in MER. If these end up working well we can update the ohai to demonstrate proper use and manufacturing of these tips.
