Having a jar of extra flux is really nice. I really love using hemostats for doing fine work. Suggest layout and building instructions. You will need some kind of front panel for mounting the tuning capacitor and the throttle capacitor.
Perhaps the simplest construction would be to make up an 'L' shaped bracket with the components on the bottom board and the capacitors mounted above them.
In that case, I suggest that you drive the brass plated nails in from the underside so that nothing protrudes through to the underside. However, the way I made my radio was how I made the original tube model back in I mounted the coil and most of the parts on the top deck and the tuning capacitors inside the box and on the front panel.
As you can guess, the exact measurements of the wooden pieces are not important. You can figure out for yourself how large to make it based on the wood you use. Top deck layout of my radio. I mounted a phone jack, the tuning capacitor and throttle capacitor on the front panel below this deck.
The battery is mounted in a holder on the inside of the bottom deck. The large black dots are brass plated nails. Detailed building instructions Begin the project with the coil form.
Just as I had done 55 years ago when I built my "Boy Electrician" radio, I used a toilet roll for the coil form. Toilet rolls are still made of the same flimsy paper that must be soaked in a dope of some kind to make them stiff and so they won't fall apart.
It seems that toilet rolls are larger in diameter 1. The next paragraph tells you the length of my main and tickler windings, but you should know that for small diameter paper rolls, you will have to use slightly more wire and thus more turns to get the same inductance. I threaded the No. It is always a good idea to make the tuning coil too long at first so that you will later have to to take some turns off.
When I was done winding I had a coil that was 0. No, I didn't bother to count windings, but there was something like 85 altogether. If you use a smaller diameter paper roll, I suggest you wind 90 or more turns. Don't worry about making it a little too long because you will take some turns off later when you make your final adjustments.
To make the tickler coil, I drilled similar small holes side by side, threaded No. Try to keep both the coils tight and regular with all the turns close together. After you have the coils wound, it might be a good idea to paint some varnish or dope over them because you will be adjusting the number of turns later and you don't want the coil to come apart.
I'll be saying more about this "cut and try" method of adjusting coils very shortly. When your coils are complete, go ahead and smear on some glue around the bottom edge and glue it to the wooden circuit board as shown in the pictures.
Just let the coil wires dangle for now. Partly drive in the nails from the top of the circuit board if mounting everything on top or drive in the nails from the bottom all the way in if mounting everything inside the box. Use the photo and diagram as a guide to where and how to place the nails.
With tiny drops of glue at the edges of the variable capacitors, glue them to their panel with the shafts sticking out. The capacitors used in this project have two sections, a pF and a 60 pF section.
For the tuning capacitor, the two sections will be bused together with a piece of bare wire for a total of a 0 - pF. For the throttle capacitor, you will use only the 60 pF section.
With the Dremmel tool and a grind stone, countersink a hole in the panel and make the wood thin enough to enable the phone jack to go through the panel and be screwed down with its nut. You may locate the phone jack anywhere you wish, but I found the lower left corner of the front panel an ideal place.
You will need some way to connect to the antenna and ground. It is up to you to decide what kind of connector to use, but I found that simple Farnstock clips are both inexpensive and very useful for this kind of thing.
At any rate, you will have to mount them on your board so you can wire to them later. Once you have the nails driven in, the antenna and ground connectors, the tuning capacitors, the phone jack and the coil all mounted, you can begin to mount the small components and wire everything up as follows: Wrap it around the nail and solder in.Aether is the personification of the upper air.
