Hammer Felder Adjustment Hand Wheel Adapter with 1/4 bit (Non-Destructive Add-On) for dial A3-31 A3-41 A2-26 A3-26 C3-31 C3-41

This is a 3D-printable drill adapter for Hammer / Felder machine adjustment hand wheels. It fits over the adjustment handwheel (also called the table lift wheel, hand crank or dial) and allows you to quickly adjust the machine using a (non -impact) power drill with a 1/4" hex bit.

I use it for my Hammer A3-31 jointer-plainer, but this dial is used in multiple models.

 

🔧 Features:

• Fits snugly over the original aluminium adjustment wheel
• Adds a 1/4" hex drive socket (just epoxy in an old 1/4" bit)
• Original hand wheel remains fully functional for fine tuning
• Non-destructive
• Dial remains visible for fine-tuning (if you use the optional internal dial gauge)
• Saves a lot of time when adjusting your machine
  
  Most pictures show an older version using a socket bit. New version uses a ¼ bit hole:

I printed in PETG

• Supports needed
• Infill 100% (at least for central spokes and crank handle hole)
• 0.4mm Nozzle
• 0.2mm Layer height

🛠 Assembly:

Simply epoxy in an old ¼ bit with 5 minute epoxy.
The model has a small exces drainage hole, so just put a liberal amount of epoxy in, and place a towel under the adapter to catch the exces epoxy dripping out when inserting the ¼ bit.

Perfect for anyone who loves their Hammer Felder machine but hates cranking the adjustment wheel all day!

Going to fast while adjusting might not be a good idea. Use a drill that has a slip-clutch system to ensure you don't damage your machine.
