Title: Broken hinge on right switch cluster - resolved
Post by: VRODDAVE on April 03, 2021, 04:05:34 PM: Sorry if this is wrong location for this post

So, was installing some monkey bars and while reassembling right switch cluster broke the hinge where brake light switch is located. Does anyone know of any way to repair this instead of replacing at 200+ dollars. I'm sure I'm not the first to do this. Any help would be much appreciated

Dave

Sounds like you have some experience with this stuff I will give it a try in the morning.
Thanks
Dave

The PlasticWeld stuff is actually a bond. Like a chemical weld. If done right it makes the two pieces one again. It's like sex but with plastic pieces doing it chemically!

Post by: VRODDAVE on April 04, 2021, 04:12:16 PM: I thought I would post photos of the repair which show how I managed to get the alinement correct while holding everything in place with my third and forth hand. ::)

I used a small pair of hemostats holding the part that ratchets closed. This aligned the nub in the hole on one side while I epoxied the broken side. ( see photos )

I plan to give it 24h before checking and then applying another coat of epoxy for durability. I'm thinking it looks promising.

I will post follow up tomorrow , fingers crossed .

Post by: Twolanerider on April 04, 2021, 05:13:44 PM: Will keep finger crossed Dave. So far looks promising. If you got a good and clean coat in between the broken surfaces you stand a good chance of saving the part. JB Weld is good stuff for these kinds of problems. Good luck!

Now onto the next issues
