JB Weld

I've heard of this stuff a few times but I've never really used it....
What I want to do is Assure, 1000% that the modifications I just made to my TB will never come un-done.
Take a look at the picture. I had to rotate part 90 degrees so I had to cut out a new notch. I obviously cut a little too much. When its in the position I want, the modified part won't move left or right, but I want to be 100% sure. If I were to run a line of JBWeld where I have the white lines, would that bond it together well enough to trust on a TB? I've never used the stuff before so I want to make sure....
As to what I'm doing... no questions now, I'm going to do a full writeup so everyone else can do it as well
I'm just copying someone else's design.

JB Weld holds well enough in many applications... personally, though, I'd just tack it in place with a couple welds. You could probably get someone at an exhaust shop to do it for the cost of a tube of JB Weld and it'll definitely hold.
That cable set-up looks familiar. Just like mine!
When I did what you are doing, I made the same mistake when cutting that slot. Mine was still able to just grab the shaft though. I locked it down with a locking washer and tightened it up. No problems so far.
Before I put it on the car I manually opened and closed it a ton of times to check it's strength, and it didn't budge.
As for your original question, if you are worried I would tack a weld on there. My experience with JB weld is that it will break under any real load.

HAH! I've been copying DeanMarcums. Its a pretty neat setup.
I guess I'll take it down to an exhaust shop, I already bought some JB weld but whatever. I'll feel more comfortable having it actually welded.
Do you have any pictures of your setup?
Yeah I saw Dean's set-up way back, and wanted to try it out. I could never find a write up from him, so I just figured it out.
I posted my set-up here in my build thread and had tons of PM's asking for a writeup and step by step pics. I didn't take pics along the way though so if you do it will be a popular write-up:biglaugh:
I did it to clear the crap off the top of the engine, here's mine.

Yeah I'm going to take picture by picture writeup.
Yours looks pretty damn close to what I'm gonna be doing.
I used one of the brackets off an automatic tb. I guess we'll see how it turns out
Is the throttle response increase noticeable?

Cool, I am glad you are doing a write-up.
The throttle response is better, not a huge difference but noticeable. The pedal feels more solid, less slack etc. Plus the top of the engine looks good. I also relocated the coil pack to top it off.
I used a cable pulley from an auto as well, works good.

JB weld is some neat stuff, and if you get a true 50/50 mix, it should be pretty strong. But whether or not it hold is more dependant on the forces it's going withstanding. Specifically, it's pretty great under compression, and good under tension, but it's not very good at resisting shear. I used some to try to fix a simple crack in my driver-side door handle, and it didn't last 3 days. Hope this helps.
Eh, I just got back from the muffler shop. The guy there has done all the work on both supras, so he just tacked it a few times and sent me on my way.
It won't be much force at all, but I defiantly don't want something breaking while i"m under full throttle!
Do it right once.

JB Weld works very well for many applications. If your are really worried about strength, then pick up some Devcon Titanium puddy. Most bearing houses carry it. We use the Devcon Ti puddy on almost a daily bases at work to repair all sorts of thing like hydraulic cylinders to bearing races on machines and equipment shafts.
