DIY PCB production - No heat transfer

I have already tried KiCad and was vastly disappointed with its great bias towards favouring SMT over THT. Don't tell me SMT is the future, other technologies that are more accessible to DIY users without the need of having sophisticated equipment can coexist with SMD. SMD also requires one to have very good near vision, something people lose after reaching 45 years of age.
 
Searching for the nearest footprint match, TO126W.fp is what I found. The contents of the file are quoted below:
##from:pcb
##for:transistor
##for:linear
##for:stabilizer
##geo:standing
Element(0x00 "Transistor" "" "TO126W" 60 170 0 100 0x00)
(
Pin(110 100 80 52 "1" 0x101)

Getting a footprint for 2SA1943 and 2SC5200 power transistors should be a matter of changing the file name and the numbers in the quote.
 
I edited the above footprint to be used as a TO3PL footprint for 2SA1943 and 2SC5200 power transistor. If someone understands the syntax, please check whether it is correct. To the eye, the footprint looks right, but that is not enough. There is a small slightly rotated square inside the first pad: I have no idea what is its purpose.


The footprint's definition text is:
##fromcb
##for:transistor
##for:linear
##for:stabilizer
##geo:standing

Interesting discussion on home PCB fabrication. I use DIPTRACE on Windows 10. I use a HP 1215 Color LaserJet. Found that colour prints work better than monochrome. I use the printer dialogue box, choose paper type as HP glossy 130gsm, set Color to Vivid and print.

I do the layout using manual mode in DIPTRACE, meaning I set X and Y axis grid to 0.1 inch, lay out Pads and Trace Lines as per size specified by me. I do use Pads from the Library for SMT. Use differ colors for Top and Bottom Assembly. I have done Double sided PCBs too.

The iron should not be too hot. Next time I am making a PCBs, I will measure and post temperature.

I am attaching pictures of PCBs recently done. I use NC thinner to remove the toner from PCB after etching.

Use a scrub and shampoo to prepare the copper surface. Do not allow time for oxidation. Use a paper napkin to wipe the surface clean before placing your printed artwork. Using the tip of the Hot Iron to ensure pressure and transfer of toner is important.

Here are pictures. Toner is not yet removed. After removing toner and wiping the PCB dry, I apply two layers of wood Polish to prevent oxidation before drilling.
 
Had to resize images.
