WANTED: Instructable on Acrylic Answered

I've only seen the end result of a project.  My college woodworking teaher had an acrylic cube that had curved holes drilled in it.  I know how it's done but would like to see an instructable on it.  I've searched and searched.  I only found a very broad article on the steps to do this but not detailed enough for me to attempt it.

If someone knows how this is done OR has experience with acrylic, please let me know if you write an instructable on this process.  If you have worked with acrylic before but do not know the process, I can explain it.

Thanks, Toga_Dan. That's pretty much the information I've been able to find. Now, to find the details and photos of the process!

the temp is probably the most crucial detail. I suggest starting at a low temp to see if it's hot enough. You're less likely to burn the plastic. If it's in an oven, protect plastic from direct radiant heat. this might burn it even if air temp is low enough.

for a large block it'll take a while for the entire thing to heat up.

Have adequate ventilation.

1) heat cube. Oven will work. I don't know what temp.

2) Squash in vice. Use blocks of wood to make vice jaws bigger.

3) allow to cool. go do somethin else for a few.

4) drill holes thru what is currently the narrowest dimension.

5) Reheat. cube returns to cube form.

6) colored dye can be squirted into holes.

The directions I've seen involve a plastics oven which I'm pretty sure a normal kitchen oven could work. I've looked up a lot of terms but memory cube is a new one. I might try searching for that. I couldn't find anything on here.

I would also like to see instructables using ABS plastic. I learned that it is used for hobby projects.

Way back in middle school woodshop I made one of those, we called them memory cubes. Clear acrylic cubes with a pattern of dyed, curved holes drilled into them. They're pretty easy to make, if I remember correctly, and end up looking really cool. The process involves flattening the cube, which later "remembers" its previous shape and reforms into a cube when heated. Hence "memory cube." I agree, an Instructable on these would be fantastic.
