I recently purchased an old motorized kickwheel second hand (originally from pottery supply house). I took it home and put it together but every time I press down on the pedal to get the wheel spinning...there's a lot of burning rubber....Have I done something wrong? Has anyone else had this problem? I saw it in use before I bought it and there was no burning rubber... When you press down on the pedal, the rubber disk makes contact with the large stone wheel and spins. It does this...but it is really destroying the rubber disk. Thanks,
Hi there, this is my first post on this very helpful site. I can't seem to find much information anywhere about using rubber to make mold masters for recreating slipcast molds. I have been experimenting with making rubber masters of my molds (mostly 2 to 3 piece molds). But I find that whenever I pour a new mold from the master, they don't quite fit together as well as the original. I have experimented with a few different types of rubber, but am limited to products that don't need degassing. Is there any one particular product that is recommended for use in this situation? I've attached a couple of photos to show how I am constructing my masters. The blue handle mold was made using Smooth-on Oomoo 25 (which is very soft), and the light colored one was made using Polytek Polygel 35. Any little tips or tricks would be greatly appreciated. Thanks
