Found out where my SB 600 is spoiled. But no idea of fixing it.

Had started a thread much earlier on my SB-600 not measuring distance. Thx to Fatigue Bro, I manage to op on my SB-600 and had a look. Found out the problem. Looks like one of the plastic has snapped (It's on the motor thing, silver in color. Will super glue help to solve this problem or is it a lost cause....
Thanks alot for any help.

Pictures are provided below.

Well done Mammothboot.
Now we know why 3rd party repair shops hate me :bsmilie:

You need to dismantle the mechanism to fix the problem.
Super glue can be used but may not last long.
One way to reinforce plastic is to embed wire inside the plastic part, just like steel bars inside concrete.
To do that, you need to heat up a wire using a soldering iron and slowly push it inside the plastic parts to be reattached.

To remove the mechanism, you need to remove 6 screws.
Some screws are under the flash tube assembly so you need to manually turn the motor to reveal the screw. Be careful not to damage the metal brush of the distance encoder

Bro Mammoth,
Next time if my flash is spoilt, I would send to you for repair

Superglue may work, but no point melting these plastics.

they are most likely thermoset plastics which will not melt upon heating

did the plastic break from the base ? or attached to the base?

if attached separately, u can machine an aluminum replica and replace it

haha. Jeff: I dunno how fix ah...I only know how see. Think Bro Fatigue is the only one who can fix. Darn....why didnt I work hard for DnT.

It's just plastic and hot wire will do the trick.
And yes, no need to melt the plastic. just bend the wires in the shape of stapler then heat up both ends then slowly push it in until the wires does not protrude the plastic

i feel this is more on skills we learn in engineering courses from poly onwards. DnT doesnt cover soldering :bsmilie:

you can do it!

after all you already consider it a gonner... might as well give it a shot.
