Fabrication 3 (platform and ramp)

To make the ramp/platform of the venue I've chosen to use 3mm acrylic. I made an MDF former box to heat bend the acrylic clotted curve on and which, I will also use to baed the angle of the platform.

I heat bent the slotted curve of the platform over the former box and then, using the interior line of that curve as a template, drew around it onto 120gsm white card. I attached the card to a sheet of 3mm acrylic and cut around the template on the bandsaw. After achieving the basic shape as close to the lines as possible, I used the bobbin sander to smooth the interior curves and get a more accurate shape. I then hand sanded the edges top make them smooth enough to adhere to the slotted curve.

Once I had the platform and acrylic curve bent to shape, I found I needed to put a chamfer on the underside of the base of the ramp to insure it will sit flush on the baseboard. I found the angle that the ramp will sit at, drew a line across the width of it on the underside and, quite simply, sanded away the excess that lay above the line until the new surface met with both the end of the ramp and the drawn line.
