Here a quick run through on setting up a magnetic switch for the Sigelei #19. The only parts I needed to source were two ring magnets.
I used these:
SuperMagnetMan and for the bonus they were actually gold plated (not that we needed that for this version of the mod)
Parts:
Small o-ring for spacing the brass post a bit higher in the delrin insulator
Braided copper wire (see my earlier post of Studiovap's mod;
http://www.e-cigarette-forum.com/fo...78-sigelei-mechnical-mods-42.html#post9614724)
Two ring magnets: 12mm OD/8mm ID - 3mm thick
Before you assemble, you will need to either bring the brass post down in diameter by ~.25mm or expand the center of the ring magnets by .25mm. They both spec out to 8mm and would not fit together. I didn't want to really touch the post so I opened up the magnets using
120/320/600 grit sandpaper wrapped around a 6mm bolt, then chucked in a drill. You need to go slow and
do not let the magnets heat-up. They will loose magnetism. They just need to slide onto the post, the less gap the better.
Step One:
Insert the post into the delrin spacer upside down. Take the preformed copper wire and secure in the small gap at the base of the delrin spacer. Bend the smaller top circle of the preformed copper wire up. This will give you room to place the magnets. This picture has magnet number one in place.
Step Two
Find the right polarity of the second magnet so that its opposing magnet one. These magnets are very strong and will flip easily. Place magnet number two over the post and wrap the copper wire over the magnet and twist tight to the base of the post thread. Try to keep the wire close to the last thread, there is not a lot to play with and you need the threads to secure the end-cap. Here is a picture of the result. Notice that magnet two is floating. The wire is preventing the magnet from popping off.
Step Three:
Replace the lock ring cap, making sure that the large loop of the wire is tucked nicely in the delrin spacer gap. The lock ring should be able to tighten all the way down. Then re-attach the button using pressure on the battery side of the brass post and on the outside of the button to tighten and lock down on the wire.
Here is my final result:
The button has about 2mm of play before firing. You can use another o-ring spacer next to the first one to bring the distance closer, but I did not have the right size, so I went with the single o-ring.
Vape performance is the same as the copper wire with the spring mod (the wire is the path of current), which is outstanding BTW. The feel of the button push is interesting. Its smooth, but the resistance increases as the magnets get closer. The push force is very light, has no grinding and the Mod stands without firing. After vaping with this for the day, I know by touch and the feel of the resistance when the mod is going to fire. I have not been able to get that with a spring yet. With the spring, it was more like push until it stops. This has a touch thing going on.
Cost of mod. - $1.50 (not including shipping...) Value = priceless.
