To begin with, a couple of other ways a point can be made 'off baseboard'
The method can be seen quite clearly in the photo and can be used two ways.
Glue the drawing in place on the card, or wood if you are handy with a saw.
Cover that with something transparent, put the CC strips on top and hold them down with masking tape.
The second is to print or copy the drawing onto thin card and stick the strips down with PVA.
If you haven't got a printer there are still lots of places to get photo copies, it's what I used before I got my first PC. I do understand that lots of you reading this will be using phones and tablets.
Soldering the top straight rail into place.
Firstly how to solder.
This is the same length of rail used in the filing post.
I've held the rail down with blue tack.
The blue stuff in the white pot is Plumbers Flux which makes the solder run better.
The solder below it is called 60/40, 60% Tin 40% Lead, it is possible to obtain Lead free solder and I have used it, it doesn't run very well at all, better though with the Flux.
I use the red screwdriver to put a small amount of Flux on the joint.
I hold the soldering iron on the joint but do not press down on it.
I swivel the iron slightly and introduce the solder under the iron tip, let a small amount melt under the iron tip.
The solder will flow under the rail
Leaving the iron in contact with the joint I push the rail down with the blue screwdriver to make sure it is in good contact with the copper strip.
Remove the iron, leave the screwdriver in place while the joint hardens.
A close up of the joint you can see that there is not much solder present.
Now onto making the point itself, you will need a roller gauge for the gauge of track you are going to make.
Hold the straight rail A/B down with some blue tack.
Then solder at point 1, make sure its straight afterwards.
Solder at point 2 and then point 3
Then solder the two strips to the left of 2
The reason for this is that the blades will also be soldered to these three strips and the strips could move unless they are soldered to A/B. At this stage do not do any more soldering to the straight rail
Once the straight rail is in place, rail C/D should be soldered in place but only at D.
File an angle to the end of C/D and make a flat so that the other short rail will butt up to it
and use the Roller Gauge to position and solder it.
(I found this pic later on today, I think it explains it far better than my words)
Looking through my pic I found this a bit clearer I think.
