@all,
Here is what I have done today, I have made up my secondary Torrid coil, it has the selectable tap in contacts, as I mentioned yesterday.

The idea is to be able to select an HT output with out getting the pinkies zapped, fried, sizzled.

There is a multi tap switch, 0-12, I checked with the multimeter to make sure where the 1st position was, this I isolated as 0v or just didnt solder any wire to it, it becomes in effect the HT off switch also.

We will begin with the winding of the secondary, the tap points, the testing of continunity and the soldering of each tap to the selection switch.

Photo0252 = Torrid, finally I got ALL 410 turns on the torrid, the inner hole became smaller each time I went around.
                    I got sore fingers, frozen fingers, crampy fingers outa this exercise, phew.

Photo0253 = Cut the ends off each loop at the "tap" point, (leave them as long as you can when wiinding them)
                    I found I had not left enough "wire lead out" lucky there was just enough.

Photo0256 = Test secondary for open circuit, should do this before you cut the ends, just in case the wire got broken wilst winding.
                    I was lucky, I got continunity as seen on my mini multimeter.

Photo0240 = Secure all the wires coming out of the Torrid by sneeking into the wifes or daughters nail polish (use the clear stuff) and put
                    several dollops where the wires come out of the windings.
                    If you tell them what you are going to do with the nail polish, they will screem No No No, find something else.
                    But its the best stuff that works, ha ha.

Photo0245 = 12 position switch
Photo0254 = Pick up HT switch, plonk in top of solder (third hand), rotate the shaft "anti clockwise" to stop on the end of travel.
                    This will be the first position, but as it will not be used as it will be OC, and is your HT off position.

Photo0255 = Test the switch, its OK

Photo0257 = all the "tap" or lead outs from the Primary are now soldered onto their respective positions.

Photo0258 = Locate the low tension entry wires, (Beginning and Ends) of the primary that was wound first, and "tin" solder each end.
                    Locate the Hi tension secondary (Beginneng and Ends), and "tin" them also.

@electricme

Great work!!!!!

Nice rotary switch.

@Timmey
No timmey, its lack of sleep, I been up toll past midnight 3 or 4 nights in a row, I'm just silly now, need to find a bed and put some zzzzz in. Besides, I like to liven up the forum sometimes lol   

Still got to take a look at some utube videos then see if I can find out what some transisters are.

Hi @ all

i got this morning an idea. What if we combine the compact camera flash circuit with the JT? Yes i know it sounds crazy but what if the foto-flash capacitor becomes our battery for the JT? Ok to use a transistor is then may be not so good idea but as IS told us to use a relay for pulsing.
