Step 9 : Iron on prep
|
| | The next step is to iron the Press-N-Peel onto the board. Here's where you gotta do a little bit of experimental work ahead of time. Techniks recommends an iron temp of 275-375. That puts an iron setting between "acrylic" and "polyester" (NO STEAM!!!). My tests have showed my iron to be a little wimpy so I had to go a notch above that. The best way to figure this out is to use a meat thermometer.
Off to the left of this picture you can see the thermometer (you can also see the spaghetti container I used as a tank this time). I place the iron on the edge of my workbench. You could do this on your ironing board, or any other temperature insensitive surface. I placed a piece of paper between my iron and the thermometer (to prevent scratching). Crank up the iron and check your temp. Most iron thermostats will have a temperature range they try to keep. I was noticing a 15-20 degree swing from where the thermostat would kick in to where it would shut off. Once I had found a good setting, it was off to the presses.
