Sawdust Spawn Thumb Press Log Inoculation Tool

The Sawdust Spawn Thumb Press Log Inoculation Tool fills drilled log holes with loose sawdust spawn. A spring-loaded thumb mechanism advances a measured plug while the other hand steadies the log, helping users maintain a consistent inoculation pattern. Handle colors may vary. This tool is intended for sawdust spawn and is not required for preformed plug spawn.

• Spring-loaded, one-hand operation
• Designed for drilled mushroom logs
• Works with loose sawdust spawn
• Reusable with cleaning and correct storage

Match the tool diameter to the drill bit and spawn instructions before preparing logs. Keep the barrel clean so spawn moves freely, and avoid compacting material so tightly that it damages the tool or inoculum. Work with stable logs, wear eye protection while drilling, and keep fingers away from sharp bit and bark edges. After inoculation, remove residual spawn, clean the tool as directed, dry all components, and store the spring mechanism uncompressed when possible. Seal filled holes using the wax specified by the supplier.
