Here I let you see how we make this machine.

\n"; echo "

We think that the machine can be made simple.

\n"; echo "

We use square pipe of steel 25mm X 25mm X 2mm.

\n"; echo "

First : we don’t have a drawing. We think and we build.

\n"; echo "

The basic of the machine is an old steel table frame.

\n"; echo "

We took the wooden plate off.

\n"; echo "

We starting with the Y ax.

\n"; echo "

All the axis are the same , only the length will be different.

\n"; echo "

The bearings are from roller skates. These are the cheapest. ( we are dutchmen ;-)

\n"; echo "

We took a piece of metal like this and we drill 4 holes in it. The distance to the edge must be all the same.

\n"; echo "

Make screw-thread in the holes and mount the ball-bearing with a bold. If the bold is to long, please grind it away.

\n"; echo "

\n"; echo "

Put the leading and the 2 blocks with the ball-bearings together and place a steel plate to it and weld them together. With a hammer you can force the a little bit together.

\n"; echo "

At the back you can make something like this to clamp it together.
\n"; echo " \n"; echo " \"homebrew_plasma_cutter31\"(This is the z ax and is only for a clamping example.)

\n"; echo "

\n"; echo " \n"; echo " \"homebrew_plasma_cutter05\"

\n"; echo "

Weld the axis together and make shore that the guides A and B are parallel. When this is not ok you get later some serious problems to calibrate the machine.

\n"; echo "

\n"; echo " \n"; echo " \"homebrew_plasma_cutter07\"

\n"; echo "

Weld the guides to the table like this

\n"; echo "

\n"; echo " \n"; echo " \"homebrew_plasma_cutter08\"

\n"; echo "

Mount the plate with the bearing block.
( this is made from an old stepper)
This must be exactly 90 degrees to the guide.

\n"; echo "

\n"; echo " \n"; echo " \"homebrew_plasma_cutter10\"

\n"; echo "

Do the same to the X ax.

\n"; echo "

\n"; echo " \n"; echo " \"homebrew_plasma_cutter11\"

\n"; echo "

Put a plate to it and weld it to the weagon on the x ax.
Do the bearing in the bearing block and drill the hole through the plate.
