Has anyone experience with mending/repairing broken plastic parts?
The steering knuckle on my MT is broken and was thinking of ways to fix without ordering a new pair because I cant find sold individually.

Does anyone know what type of plastic the steering knuckle is made out of? I was reading all plastic is not the same and requires either a glue or solvent.
 
I've seen guys try to use shoegoo to mend pieces back together as a very temp fix but it almost never lasts very long or accurately.

That part is under too much stress to last long with glue. best just spring for several sets of those broken parts when you can afford. As for gluing parts under less stress--- buy this- its for real and works.-- 99% of the other plastic glues are garbage.--- LOKTITE Plastics Bonding System. fuses hard to bond plastics. www.loktiteproducts.com. Its a 2 step system. Activator & bonder.

I think you're wasting time. The plastic cement that plumbers use is used to hold pipes together not support a huge monster truck while is goes bashing across someones backyard.

But give it a go - looking forward to hearing how well it works out for ya. ;)

agree. zero chance. best just buy several new sets- thing is about the super glue i mentioned- it requires a clean break- where its just snapped apart and not tore apart- a flush fitment. there are a million types of plastic, the glue i mentioned will fuse more clean break parts back together than most. Plastic. there are 5 places in the worlds oceans where plastics-collect-- the largest one is between hawaii & califorina. about 2 times the size of texas. off topic i fully understand- just wanted to toss that out to folks.
 
They have a new plastic bond by JB weld at walmart , two parts epoxy that lists 3300 lb break strength and various types of plastics it works on is listed on the back, but even still, its a 5.00 risk I could apply to the new parts instead. I looked at the loctite plastic bond and listed only 2500 break strength. What I did think of doing to add strength if I did decide to do the JB weld experiment, was to drill two small holes in both pieces, put screws in, cut off the heads of the screws, then bond the two pieces together (like pins supporting a broken bone).
 
well its bonded, Ill let dry 24 hours then take it out for some serious bashing, flying off cliffs and other fun stuff... I still bought the new ones though because I'm just not sure about this glue/bond stuff anymore. They make it sound impressive on the package. One example is...its 3800 lbs "tensile" strength. Heck, for all I know that could be those shiny things that hang from a Christmas tree.... :0
