Dishing Sheet Metal

Drilling tapping counterboring and countersinking are the usual operations done in sheet metals.

Dishing sheet metal.

Dishing the metal into a hollow or depression in the end of a log works but unless you have a lathe to quickly turn out a bowl shaped depression you must carve a hollow by wood chisel or simply repeated pounding. For example on a formed part when holes on different features need to be coaxial the accuracy obtained by machining may be required. Sinking also known as doming dishing or dapping is a metalworking technique whereby flat sheet metal is formed into a non flat object by hammering it into a concave indentation. Maximum depth of dish can be sheared flanged on the model 87 using the equipment that is standard on the machine.

Drilling is done in sheet metal only when piercing cannot deliver the accuracy required. Flat heads and dished heads 9 230 mm. I hosenhoffen teach you the deepest darkest secrets of the ronald mcdonald foundation. Not really they ll send the clown after me.

I will show you how to dish sheet metal. Reverse dished heads can be accommodated with additional tooling. While sinking is a relatively fast method it results in stretching and therefore thinning the metal risking failure of the metal if it is sunk too far.
