Hey Charles.
On both the NarDa and the NarCa, I think it is Easier to Mount the Coil when it is Not On a Mandrel.
I just bend the Legs of a 3mm Coil so they are pointing in the direction of the Coil Axis. Like this...
View attachment 726097
In that view, all of the Coil is above the Legs. And the Legs are laying Flat on the Table.
Then I back Both Screws out enough for the Legs to fit under the Screw Heads. Then I mount the Coil not really worrying about the Height or angle it is sitting. Just Centered.
Once the Screws are Tight and the Legs are Snipped, I take my smallest Mandrel, a 2mm, and put it into the Coil resting it on the Top of one of the Screws. Then I pry the Coil Up until the 2mm Mandrel is level with the deck. Then I switch sides and do the same thing to the Coil resting the Mandrel on the Other Screw.
Now the 2mm Mandrel should be able to go All The Way thru the Coil. and I Rotate the Coil (away from the Leg leaving more room for the wick) so it has a Slight Angle like the pictures Asbestos posted.
Once it looks good, I hold the Deck up and Look across the Air Inlets. I like the Coil so that the Bottom of the Coil is lined up with the Bottom of the Air Inlets. Which, if you are using a 3mm Coil, is also the Highest point on the Deck.
Now Dry Burn if you Dry Burn your
coils. And Wick like Asbestos's picture. With a Single Tail on each side.
That's how I do it. And once you do it a few times, I find it to be Pretty Easy.
The Key (for me) is Not having the Coil on the Mandrel. And doing the Lifting/Rotating with a 2mm Mandrel.
