How does a train pantograph work?

How does a train pantograph work?

The pantograph is spring-loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train. As the train moves, the contact shoe slides along the wire and can set up standing waves in the wires which break the contact and degrade current collection.

What is a 3d pantograph?

This instructable is to build a 3d pantograph. A pantograph is a device that is used to copy pictures by tracing the original picture and the device draws a copy. This pantograph will let you carve or engrave a picture into a medium such as glass, metal, or wood. You can also trace a carving and reproduce it.

What does a pantograph do?

Pantograph, instrument for duplicating a motion or copying a geometric shape to a reduced or enlarged scale.

What is the best wood for routing?

As a rule pine will be the cheapest, but the best choice would be cedar. Fewer knots, a soft wood that routs easily, still low in cost.

What kind of carving machine does Matthias Wandel make?

I can get stuck there for hours, so be careful when you click through. This time it’s Matthias’s homemade 3D pantograph carving machine / pattern duplicator that I’m fixated on. Mechanical pattern-copying machines like this, of course, are not new.

How does a 3 D router pantograph work?

3-D router pantograph This is my 3-D router pantograph. Unlike other router pantographs, this pantograph also controls the router’s depth of cut. This is is achieved by tilting the whole pantograph back and forth as the follower moves up and down. The pantograph supports the router’s weight and thus precisely controls its height.

What’s the best way to make a pantograph?

I cut a rabbet 3/4″ wide and about 1/4″ deep down the middle of the 4″ piece. Then I rounded one edge of the 1 1/2″ piece, drilled a 3/16″ hole, and glued and screwed it into the rabbet. I left a 3/4″ space at the bottom because this will allow the pantograph to slide a top and bottom over this piece and a pin to go through.

Who is the inventor of the pantograph jig?

His name is Matthias Wandel and he approaches his work with a great deal of mathematical analysis. He made a jig for cutting “finger joints” that is very impressive. Then I found his video on making a pantograph. It looked like something that I might find a use for and enjoy, so I started my search for making my own.
