Prepare heat press machine and aluminum frame

Heat press machine...commercially available heat press machine for iron-on printing. The one I am using has a 350x350(mm) heat surface. Aluminum frame...I found a supplier online that sells and processes aluminum sheet metal and placed an order. 230x300x4(mm) rectangular frame with 5mm radius on the corners. This aluminum frame is sandwiched between two aluminum sheets (2 mm) and pressed.

Steps 1 and 2 are based on "Zero Plastic Australia's Sheet Machine" by Zero Plastic Australia. Please refer to this one too!
