QUESTION #5:

Can I make the eccentric shaft MK.98/M15 completely out of stainless steel and if so what grade do you prefer?

Can I make lock plate 99/M15 and keeper plate 100/M15 by laser cutting out of steel plate and if so do I still need to machine both faces?

Do you happen to have a picture of this completed product

ANSWER #5

The shaft can be made from stainless steel using ASTM A 564 as indicated in section 05 50 15, paragraph 2.1.2.2.
