This is the new style arm and bracket which can be an upgrade to the old machine. The new style arm has a flat upper arm which is longer than the old style making it easier to sharpen longer shears. It is also milled flat for checking the alignment.
Installation is somewhat complicated and the machine must be taken apart to install correctly.
This set includes the 3 pieces of the arm plus the bracket and bearing discs. (Bracket and bearing discs are not pictured.)
The discounted price is only for Scimech owners.
To install in an older Scimech please follow these instructions: https://drive.google.com/file/d/1m4U0gw9jNv3rV1rPToaosWlJ-gNoDLV2/view?usp=sharing
