Locktite on shafts

[Just for Fun]

I know that some use wire drives that are glued with locktite, but has anyone used locktite on 3/16" flexi cable?

Yes, you alway can use Loctite for either wire or flex shaft but i recomending you using Permatex sleeve retainer over Loctite, its much easier job and no due date, i seem alot of people their shaft get loose after years or even month if they did not do perfect job (sanding, cleaning), with Permatex, you dont have to sand it, just clean it with acetone, set them up and leave them over night, my shaft is still strong after years by using it.

I did it with loctite and lost a coupe of good props... lesson learned.

603 is for a slip fit only. There is better and stronger.

Out of hundreds and hundreds made with LT I have virtually none let go. Some have been running them for years.

I will look in to the permetex but loctite is what is used by 90% of the good machine shops.

You never want to do anything until it is cleaned good. Octuras has a ton of goo left in the bottom of the stub. I also dry drill mine...no lube.

Sorry but 603 is for a press fit with a maximum gap that is 0.005". Slip fit 638 may work but the maximum gap for this is 0.015".

My customers have been using 603 with great results for years. So have I. To each his own.

Boy this blows me away! I love the idea of not soldering as has been my only exp. for 30+years but boy I just get the jitters thinking something is bonded and not soldered with silver solder. My prop collection is very impt to me and the thought of loosing even 1 because I didnot solder vs bond would make me fell like it was my own fault.
Iwant to convert to this if it will really hold the tremendous rpms and torque combo of electric. Will this process work with larger props like say 447-455 and 3 blades too?? Also, wouldn't the oils inside the flexshafts effect the bonding process same as it does with soldering? Heating up the shaft to cook out all of that would seem to be necessary with bonding or soldering.

I've been using 603 for everything and never "cooked" the flex but instead soaked and cleaned the flex and shaft interior with acetone.Never had a failure.I twisted a .150 flex in 1/2 in my KB45 powered 41" mono (gone to 3/16" welded now) but the 603 held up fine

So is the 603 a red locktite name brand of locktite or a term you all are using?
Also, the permatex mentioned, is it a direct compet. to red locktite?

Ok, now could I use JBWeld? I have a good working knowledge of it and its holding strength. It will "weld" 2 metal surfaces for life. It can be drilled and rethreaded, and has no enemies with regard to corrosion either.

Locktite 603 is designed for use in an "oily" environment where clean surfaces can't be assured. It will cure with up to a 0.010" gap with reduced strength. It is designed for slip fit, shrink fit AND press fitting - RTFM.

I have used it on wire for many years with great success. Failures were either with the wire breaking, or one batch of drives I used an out-of-date bottle of 603(!). This product is significantly different from those Locktites designed for locking screws.

Do not use JB Weld. For cables, some have had good luck with the Permatex retaining compound.

Have you clicked on the tips/Info on the top of the home page, including how to use 603 for prop shafts.
Also the power transmission of electrics is much smother then with IC engines. IC engines are accelerating and slowing down every rpm.
