So, I am new the world of Reo's. About two weeks ago I received my Reo Grand. Since I was busy doing micro coil wizardry with super_x, pdib, statistic and whole bunch of other guys (gals?) over in the other Micro-coil thread, the transition was easy. I really enjoy all the features that the Reo has and I wont re-cap, you guys know what they are.... So why am I posting?
The one issue I have with the Reo is a periodic misfire. It only happened to me recently. I mainly vape sub-ohm coils so this may add to the effect. My understanding is that this occurs because of oxidation. The only solution I could find is to file down the firing pin and reapply Noalox, The fix worked to correct issue, but it return a couple of days later. The issue happens more often with flat tops than with a button top. So I took a closer look at the firing pin connection to the positive terminal of a flat top. Apparently, there is an arc'ing effect which I believe is due to the small surface area that makes contact. At the end of the firing pin is a slight curl and contact is not optimize for lower ohm coils IMO. Here is what I saw:
So to address the surface area contact, I placed a thin strip of copper (.2mm thickness) around the end of the firing pin. The copper was thick enough to be able to conform and "lock" onto the end of the firing pin with a slight pinch from a needle nose pliers.
The contact point is formed to increase the potential contact area and is adjusted so that inadvertent firing on the atty can not occur. I have tweak it to also work with button tops as well. There is enough play in the switch throw to accommodate this.
The result is very apparent, no misfires, instant on connection and full power delivery. When the device is lock it will not fire.
The usual disclaimer applies here. Mod at your own risk. This mod can result in a very bad situation, if you dont know what that can be, then dont do it.
BTW, this is my new addition and current favorite device.
