This video has been uploaded with kind permission of Sika Tooling & Composites. Its runs through the process for producing a low cost and effective metal sheet forming tool using a combination of SikaBlock board and Sika Biresin. The SikaBlock M950 tooling board has now been upgraded with the SikaBlock M940. You can also use SikaBlock M960 & SikaBlock M970 to achieve similar results.
The video also shows how sheet wax is used to as well as the face casting process, excellent for casting large tooling.

@bullseye911 it is always difficult to put an exact number on a process such as this because a lot will depend on the thickness, complexity and type of metal that you are pressing. This type of set up is normally good for prototype and short series batches.
