can someone tell me how to solder a flex shaft?

[dana]

just want some info please. thanks. im trying to solder flex shaft to prop shaft

[Fluid]

I strongly recommend that you do not solder the flex cable. Few people can do it successfully, and the result is usually a lost prop. Cheaper in the long run to buy them pre-assembled.

A better method for the average hobbyist is to use Permatex retaining compound instead of solder. Several top racers have used that product with good success.

FYI, there is a How-To page located in the Tips/Info page:

well ive already tried it. hopefully it works

[Gerwin Brommer]

The european way :

For steel/steel : loctite 648
For steel/stainless steel : loctite 2701

yea use the green stud locker loctite, I used it on my bj26 and it works great, never lost my prop.
anyway if you do choose to solder it should be silver soldered.

Yea i tried 3 types of solder on my current build and only one held. In the vid you can actually see the boat as the solder comes loose.
I had room for set screws so i put set screws in it and it is holding a lot better now. That is my least fave part of building a boat.

well guys my first attempt done with a soldering iron last nite "suprise suprise" didnt work. so i got a torch and tried again and works! i used plenty of flux, thinner to clean the bore on the prop shaft and a round file to marr it up.... now the boat doesnt want to stay in the water!!

[Ronbo]

what about loctite 609. have a bottle at work.

[z400]

We gave him the best solution and he still soldered.


The assembled drive lines from OSE dont even come soldered.

[forescott]

Yeah, but he was just asking for soldering advice. We all think our way is better!

LOL

Man, i hope i didnt sound like an azzhole up there.
I just read it for about the 5th time, im sorry man.

Next time you wont need to go through all the hassle.
Take some sand paper to the end of the flex cable.
Scar up the inside of prop shaft with a drill bit.
Apply the Loctiite and slide er in.

Its pretty simple.
Have fun boating!!

Staybrite solder will do it fine. It is the coating on the cable that makes it tough. Staybrite has an acid base flux...many will say NO do not use it as it will eat you cables. No it will not. Sand the cable well aqnd clean it with acetone. Also clean the stub out...any octura stub has a bunch of machine lube in it..

You cut several small pieces and drop it in the stub hole then slip it over the cable in a vise with the cable sticking up and torch it until the stub slide down all the way. Clean it up and you are good to go.

I silver braze them and that takes 1100 degrees and the cables do not get soft from heat....the best cables on the market are made that way from a man named Ed...more records than you can count.

I also use loctitie on mine and it works.

yes thank you all for replying to this add. i am familiar with the glue in method but i didnt really want to wait overnight. nevertheless i used some silver solder and a torch and it worked out fine. maybe next time i'll try the glue, but hey, i didnt really feel like the solder in method was that hard. plus it was ready to go 2 minutes later. woohoo!!!!
