Use

In most workshops, uses for the bender will be limited, but having it available will make projects possible which would otherwise be impossible. Typically, a machine guard can be made from transparent plastic and a plain flat sheet may suffice but placing bends in the material could make a guard that gives superior protection and will in any event make the it more ridged .

 

For examples see this page. However, the shroud in photograph 31 has one bend, that on the front edge, having small bubbles on the surface due to overheating. This is best seen on the enlarged view. Whilst this can be the result it in no way affects the final bend other than visually and in any case has to be greatly overheated for this to take place.

 

As the bender can be made so cheaply and rapidly it could no doubt warrant its manufacture just for a one off application, so keep the idea in the memory bank and make one when the need arises.

 

Materials

The material that I bent using the device was acrylic sheet, as sold by DIY outlets as an alternative to glass. I do know though that other plastic materials can be bent in a similar manner but am reluctant to be specific as my memory cannot be relied on.
