Seems to me awfully difficult.
("A crutch, a rubber crutch" if i may quote bob pease)

I mean it's ok to want to avoid a laminator or fuser, but come on!

Probably better than nothing, but as you see he still doesn't get perfect
transfers, which you will get with the real deal.

The last board I did I finished it off with a 6" rubber roller from my photo lab, came out perfect.

I placed paper and board inside a newspaper with about 6 sheets above the board and the iron on top. Move it about for some minutes without using very much pressure. When it's hot and good remove the top sheets and run the roller a few times pressing down hard. There did seem to be some spreading of the toner but I'm not sure how much because of the rather wide traces and spacings.

I'm still experimenting on papers and techniques, I'll make a write-up once I have more consistent results. Don't hold your breath.
