Flex shaft to prop shaft??? silver soldering

[dlewis0831]

Hey guys,

Thanks for all your help so far, all you guys are awesome. So I got all my parts yesterday for my apparition. I was not able to find an assembled 0.150 flex shaft with a 3/16th prop shaft. I have the tools and supplies to solder the prop shaft to the flex shaft. I ended up with Octura brand flex and prop shaft. I have searched for a basic how to, but only have found basic tips and tricks to do this job. I'm about to just loctite it using the instructions that OSE provides, but I thought I would give silver solder a try since I have the supplies and equipment to do it. The silver solder and flux I have is Oatey brand from home depot for plumbing. Thanks again for helping a newbie out.

I like to use stay brite solder with liquid flux, I just cut a piece of solder drop it in the prop shaft hold the flex over top of the shaft heat up the prop shaft and slowly press the flex down untill the solder bubbles and wicks all the way up then whipe it with a wet rag. Works great for me.

Edit: wear safety glasses if you press down to fast solder can shoot ot press slow and let it wick

638 or 609 loctite retaining compound is an easier option and just as strong.

Ditto, and for my money I'll say stronger. I have yet to have one let go. In the old days I soldered and had a few let go.

This is how I do mine too. .150 is easy but doing .187 is more of a challenge. I got it perfected tho.

Thanks for the input guys. I ended up ordering a "welded" .187 from Kintech. Not sure of the quality, but we'll see soon enough. I am still going to try myself to with the one I have. I was iffy about the loctite, but didnt realize how strong it was.

Loctite works great, just make sure you throughly clean and prep both joining pieces.
