For the manner in which men live is so different from the way in which they ought to live, that he who leaves the common course for that which he ought to follow will find that it leads him to ruin rather than safety.

Die Filer (part 3)

Where do we start today....

Let's work on the main body of the filer, shall we?

Having a conference with my good friend, Sammy Smith, to discuss clamping. This was a part that I had to think about. How best to hold this casting for machining the first surfaces that would then determine the placement of everything else?

Die Filer (part 2)

So...onward and upward. Or something.

For Part 2 we're going to focus on the Scotch Yoke. Like many cast parts, this has no reference surface to start with. We have to figure that out for ourselves.

Die Filer (part 1)

This is a project that I started some time ago. I've done a lot of hemming and hawing over how to do it, and I'm now knee deep in getting it done. Here goes...

Oh, first things first. I s'pose I should answer the question, "What is a die filer?" Simple, it's a small, motor driven, benchtop machine that drives a file. The rotary motion of the motor is converted to reciprocating motion by way of a crank shaft/pully combination. You rest your work on the table and move it around the file. Trust me, it will make sense.

 Here is the basic casting kit as it came from Martin Models. There is a base, table, pulley, and scotch yolk.
