Cracked plastic. Best way to repair?

[KEITH KRAUSE]

A pic' as promised, to those who want to see it. I decided to cut the ducktail off the end of the chainguard. I never liked it much. The crack was right where I would have cut it anyway. There's still a small amount of crack left but I PVC cemented the backside and I think it will be fine.
So the crack gave me the excuse to modify the look. With less material "after" the crack, I don't think the crack will re-open from vibration. I'll be ordering an NOS guard just in case. Need to get myself something for my birthday coming up. Sorry the pic's arent that good. I should've used the better camera.

as always.... bravo :-D

Wow Keith, that's one clean ride. Oh, and the mod looks fine.

WOW!!! That's one clean GS. Mine with 1/10 the mileage you have on yours ain't that nice. Maybe if I retire I'll have the time to put into it.

Thanks! Actually, the bike's a little dirty right now, at least to me.
It's almost time for its 5-6 month polishing ritual. It does take time. I'll be taking a vacation day in a couple of weeks to polish her up. I gotta get her ready for the big annual ride around here. I have 350 vacation hours saved so I can afford it.:-D

one day i was at lowes and ran across the step by step polishing compounds you recommended. they were in the tool department.
great job on the duck-tail!!!!!!

cracked plastic,best way to repair

cracked plastic,best way to repair

get some abs plastic pipe cut some slivers,then with a soldering iron apply the iron to the slivers and the part you want to repair and fill the crack taking care to melt it all together.i repaired my tail piece this way and it has not cracked again.

 

[KEITH KRAUSE]

What!? This is a tech question?
Sorry Frank. I kind of thought it fit into the general section. More or less how do you fix plastic.

I am SO glad I have a chrome chain guard on my bike......

Nice work on the mod!

Thanks Sandy. I'll ask about the true condition. I'll probably just order a new one unless this one is perfect, which I doubt by the description.
I need to get myself something for my upcoming birthday(from the wife). If I don't, she'll get me something I probably can't use anyway. I'm at that point where I'm really hard to buy for I guess. So in a way, an NOS one won't cost me anything. It's still not about the $, it's about keeping the bike as nice as I can. I actually prefer the modified version I cut. The NOS would just be used if the crack came back.
Thanks again for taking the time.

Keith, that ducktail wasn't put there just for looks. It added considerable rigidity to the chain guard.

I haven't noticed any difference as far as rigidity. There's a metal plate at the rear that seems to take care of that. I don't see how the ducktail makes it any stronger. Maybe it does but I still have no issues. I think the mass of the ducktail being "after" the crack would eventually open the crack again from vibration. It can't now and I like the look much better now. Thanks for the reply.
