Bark-Scoring Tools to Repair Tree Grafts

MTDC Modifications

Early in the project the Woodzig bar with wire chain was adapted for mounting on the Makita saw (figure 8). The original bar and chain was more versatile, allowing the saw to be used on larger trees, so this approach was dropped. Modification of the chain bar on the Makita cordless chain saw (figure 9) includes:

• Removing the factory tip guard.
  
  
• Grinding the rivets flush with the bar and staking.
  
  
• Fabricating and installing the MTDC guard.

Figure 9—The MTDC modifications of the Makita cordless chain saw
for bark scoring included removing the factory tip guard.

The materials cost about $10 with 2 hours labor for all modifications.

Modification for the Wizard (figure 10) includes:

• Fabricating a circular Lexan guard.
  
  
• Purchasing a 2-inch-diameter Arbortech industrial saw blade.
  
  
• Fabricating an adapter to mount the Arbortech blade.
  
  
• Purchasing a ¼-inch arbor so the adapter can be mounted on the rotary tool.
  
  
• Fabricating a holster for the Wizard (figure 11).

The materials cost about $36 with about 2½ hours labor for all modifications.
