Introduction: Foldable Ax

Picture of Foldable Ax

For our school we had to make a flat pack product. I had this crazy idea to make an ax more flat pack and portable.

here you can see the final result:

Step 1: Needs

Picture of Needs

Materials you're going to need:

  • access to a welding machine
  • old axe head
  • square tubing 16 x 16 mm
  • hardened shaft diameter 8 mm
  • flat iron stock 5 x 25 mm
  • flat iron stock 2 x 20 mm
  • 2 bolts M8
  • some wood

Tools needed:

  • welder
  • angle grinder
  • assortment of files
  • sanding paper

Step 2: Grinding the Ax Head

I found this big old axehead that was perfect to grind up into a perfect blank for this project. the axe head must have minimal the dimentions shown in the diagram.

Step 3: Cutting the Handle

Cut the square tubing into two pieces one 26 cm long and one 16.5cm long. now cut eight pieces of 6 cm out of the flat iron stock 2 x 20 mm. and weld them onto the end of te square tubing.

Step 4: Hinge

cut four pieces of the flat iron stock 5 x 25 mm with following lengths. weld them together folowing the drawing.

Step 5: Drilling Holes

Drill the holes trough the pieces according to the diagram. Al the holes need to be diameter 8 mm

Step 6: Ax Head

Weld the two smaler pieces together to get the right thickness and then weld them to the ax head

Step 7: Welding

Folow the drawing and weld the pieces together Into a U shape.

Slide this over the end of the shorter tube section and weld it in place.

Step 8: Sanding

Cleaning up the welds and grind al of the pieces to size.

Step 9: Finishing Touches

Weld two little pieces on to the bolts.

Cut two small strips of iron stock and weld them to the ax head. use the correct angle.

Screw the bolts in the tubing and use a dab of epoxy so it can't fall out. Make sure it can still rotate.

Step 10: Making the Handle

Cut a slot into your piece of wood 16 mm wide and 8 mm deep. Make the slot so it is aproximatly 6 mm from the long edge.

Saw this into four pieces two need to be 26 cm long and two 4.5cm long

Glue the short one onto the shorter peice and the longer onto the long piece using some epoxy

Now sand the handle to a more confortable shape

I'm curious about this one. Was it ever put into use? How did it work "in the field"?

The idea has merit but, like everyone else, I fail to see how well it would work when hitting something hard. Maybe a better idea would be to half a piece of pipe and fit it out so that it can screw together to make a handle, then screw that handle to the axe head. Even having 2 rods that could slide down a hole in the handle shaft, with the ends only meeting in between 2 pivots, would greatly improve the handle strength.

Neat idea, but your going to have structural issues. The truth is steel bolts will eventually do one of two things, it will either rend through the steel or the bolts will break. The problem is that a lot of force is going into the handle when you chop wood and such, and why a cool concept it probably won't work as a tool.

Thanks for your comment,

You are right, The structural issues are definitely a problem in this design and those need to be addressed to make a more usable ax. This is something I will keep in mind for a future redesign.

A remark on your bolt theory . The design is made so that the bolts do not take up force during chopping. They are only there to hold the ax in the unfolded position. Nevertheless it is probably the hardened shaft who will break or the holes that will deform.

Hi mate, I like your idea. However I have to agree with previous posts that whilst being a cool project it probably won't work as intended. Have you tried it out yet?

Cheers Alex

could have the handle pulled apart, using a pin to hold in place, I would imagine that would solve the prior mentioned issue.. however the head needs to be properly balanced, or you will have difficulty chopping
