Auto Spira-Tel YS 105mm F2.5 Test

Got this with a-mount adapter glued on it's original mount.
After a few test shots, its adapter comes off. Wonder if I can weld it... Anyone have experience welding adapter to lens mount before?

I'll take out the mount from the lens first and ask a friend, Gatot, the best welder I ever know to work with it then. :)

Gatot is one of those crazy guys. You see, one time, my motorbike's exhaust system's hex bolt to the engine's combustion chamber broken. The bolt's head fell off somewhere, leaving its body deep inside the hole where no tools can reach, so there is no way to unscrew it and replace it with a new one. Normally, we must take the engine apart, melt the broken bolt inside, then make a new helical ridge.
But he just weld a tiny metals into the part INSIDE that tiny hole then use pliers to unscrew it.

Hope he can do something somehow. :D

Yessire, you are right. He said he can't do that since it isn't made with the same material. Plus, if it is, then it is to thin to weld. :(

But he said that a threebond super-glue mixed with iron dust will work just fine. He'll do it tomorrow. :D

Here is the result. Before the mix applied, he makes three small cuts using grinder on the adapter for screwing the glued mounts back to the body later.

He run out threebond superglue but nothing to worry he said, because using another super-glue, Proton cyanoacynclate adhesive (we call it Lem Cap Badak here) will work just fine.

Here is how he do it. First, he glued the two piece together using only super glue, then, he spread the iron dust on it's side surface where the two piece met. Next, he drop a few drips of glue, then heated the mix using burning cigarette.

We did a few test later, fall test from second floor, pulling it apart, even boiling it, and it is still intact. He call the technique "Poor Man's Welding."

Well, of course yes.
If not, this post will be full of me, crying.
