2021/22 Rocnel Sailor Adjustable

On one of Murat’s Instagram posts I asked how one could take apart the Sailor and he said with a heat gun. I did not ask any futher details.

The head is indeed held to the handle by epoxy. Murat confirmed this awhile back.

Im not very good at these things but isn't epoxy what brush makers use to glue knots
into handles? And we still see cases where knots fall out of handles (it's happened to me
with a Thater)

Why would this be the best way of doing things, I wonder?

My initial thought was that dropping this razor could weaken any epoxy bond...but then I remember
GlazedBoker dropped his from a height of 14 ft (sorry to raise that again)...and there were
dents suffered but the bond between head and handle persevered.

The '19 and the '20 are both glued together.  I have heard the '21 is not but I have not confirmed.  My '20 came apart and Murat told me how to get it back together.  You want to use  Loctite 480.  It will cost you about $30.  After you clean the parts and dry, use only the amount shown in the toothpick picture below.  Apply it to the vertical surface on the head only.  If you use too much 480, you are going to brick the razor.  It will get into the mechanism and lock it up.  If you look at the first picture, the clear black ring is the Loctite.  This demonstrates the proper amount of adhesive.

My understanding is heat is what releases the adhesive although a thorough reading of the product literature may reveal more information.  

Heat the neck with a heater gun, and the razor comes apart.  Mine loosened form very, very hot water. You then pop the pin out of the base of the handle.  From that point, you are own your own with disassembly   My guess would be if you brick it, boil it for a little bit and it would likely free it up.

Claudio and I had some discussion a couple months back about it.  He may have taken his down by now.  Hopefully he will chime in if so.  

What is this?

Can someone confirm this....I would much rather the 2021 MC was not glued together. I'm just awful with
all these DIY things y'all are so good at.

Something else (thanks for the pictures and explanation Loot, might come in handy in the future although I hope not to encounter it).

On my Sailor 2021 when I insert a blade and tighten the razor up it's exactly at the dot on the minimum stand.

My Sailor 2020 however is then at just a tiny bit past 1. I asked Murat and he wrote back:

The product must be used in the 1st stage. Depending on the thickness of the blade, there may be a deviation towards the 1st level. The gap between the dot mark and the 1st stage is for calibrating.

So does anyone have the same thing happening with the 2020? Doesn't affect the shave in any way just seems a bit odd to me. The sailors are still as good as it get in my den.

Not sure about the original material used, but Loctite 480 is not an epoxy but a cyanoacrylate (in the "Superglue" category - short working time). It's technically a reinforced cyanoacrylate to improve flexibility and moisture resistance - and very good bond strength. That said, like all resin adhesives, it's subject to failure under high heat or exposure to chemical contaminants (like organic solvents) that affect the chemistry of the bond, and it's not completely impervious to moisture but just very resistant. The good news is, as above, it's easily replaced and repaired, unlike stripped threads or a broken weld. Resin chemistry has for years been used in the automotive and aerospace industry for bonding metal, but has limitations like any other joinery. Like others commented though, it wouldn't be my first choice for connecting stainless steel razor parts, easy disassembly being just one of the limiting factors. Rocnel has been around a few years (although I suspect a limited number in use) and I haven't seen a significant number of bond failures reported, although aging is also a factor in resin bond strength and a decade or so in the hands of shavers might be more revealing.

Ok, my bad, so it's the dried up ring of loctite that loosened and fell off.
I am now wondering how one applies this in a perfect circle without any spillover to the
sides that might harden and stay there...where is it applied: Point A or B?

My guess: B?

Ok....feedback received....I will presume this only applies to MC
No Loctite used....pieces are fitted together like Lego bricks (tight fit) with a proprietary
chemical formulation to prevent loosening over time. Hot water will not cause harm.

Also, no to chemicals that can dissolve the oil on the shaft or wear away the gold coating on the ring.
So... no using isopropyl alcohol.

Wow....there are times I actually soak a new razor in just boiled water, liberally mixed with isopropyl
alcohol for about 15 minutes....guess that's a no-no with this razor.

I remember reading similar advice regarding certain vintage Gillettes like the Diplomat which feature
a gold coating protected by a layer of lacquer. The advice given was not to use alcohol soaks and ultrasonic
cleaners on such razors.
