I used Xerox and HP lasers with glossy photo paper and a hot domestic iron
(not all at once - do keep up at the back there)  ;D

I'm sure I've mentioned this in the past.   I have basically used GOOTEE's method for years now.   It's the only way I do it... including NOT using ferric chloride.

That's one of the online tutorials I read when I was 'investigating' the TT method. True to say it was the most influential for me  :) Here's to GOOTEE!

The trick is to go for semi-glossy photo paper and avoid those expensive glossy papers. Any iron would do and use adequate design clearance in PCB design.

Fenrisulfr, I have the same laminator(from asda, £7).  What did the mod consist of?

Hi there.

Inside the laminator there are 2 sealed thermostats. These need removing. They are in series BTW.

The replacement thermostat is from an old clothes iron. It was fixed to the iron by a machine screw so was easy to remove.

I then used the same screw to fix the irons thermostat to the laminator. I gut a groove in the bolt up it's length for a 1/4" so it would cut and clear it's own thread in the aluminium channel. The bolt needed cutting slightly shorter so it would hod the thermostat securely.

There is also a thermal fuse strapped to the aluminium channel. Remove and join the wires together. The wires from the original thermostats connect to where the irons wires were on it's thermostat.

Do ensure that there is no possibility of making the laminator aluminium extrusions MAINS LIVE!

The plastic case needed a hole cut in it as the thermostat is quite tall. I built a shroud round it to prevent any issues with touching mains live parts. The dial is fixed with silicon sealant.

THIS IS MESSING WITH MAINS POWER PLEASE BE CAREFUL!

A thermometer would be handy as well as the scale on the irons dial isn't exactly accurate and it is easy to get the rollers smoking!

The largest PCB I have done with it was 5 x 4 inches. My unit is getting a little tired and the gears in the AC motor gearbox start slipping if the unit starts getting to warm. But it has done a lot of boards.

If you do not absolutely know exactly what you're doing, DO NOT RISK IT...

Fenrisulfr

Absolutely. If in doubt just use the clothes iron as is. It is a knack and practice will pay off.

Yet another PCB making tutorial. But this includes a UV LED light box.
