Help me figure out what these are used for?

[hanau]

Bought a lathe a few years ago and found a couple tools that not sure how they are used.
First are metal lathe bits that a hole was drilled in the end and a bolt was pin in it.

Next picture is a Dayton sped controller trying to find model number form to locate the manual.

That was hooked up to the dewalt trim router.

pic #1 = look like tooling forr a machine shop lathe

pic #2 = it is a control for a wood burning kit/set

#4 = looks like a dewalt plunge router

Speed controller was used to make the router variable speed. Small trimmers like that turn at 20,000+ rpm which is a little fast for anything other than trimming off thin material. Not sure why there are handles on the carbide cutters but they are used for turning metals.

The speed control is quite simply that -- plug it into the power, plug the trim router into the speed control.

You can choose whether you want clockwise rotation (by flicking the switch to the CW position) or counter-clockwise rotation (by flicking the switch to the CCW position.)

Adjust the speed using the knob on the right.

A cutting router bit will only work in one direction -- it must turn so the the cutting edge turns into the workpiece. A grinding bit (like a file or a grindstone) will work either direction.

Its also possible that he was using the speed controller for his lathe motor.With Reversible direction and variable speed controls. it will handle up tp 9amp load.

It looks like the trim router is mounted in some kind of jig that holds it at 45 degrees to horizontal.

Does it slide from side to side?

If so, this can be used to do a number of tasks.

For example, if you have an indexing head on your lathe (whether built-in or as an add-on) you can use it to make faceted barrels. Or cut grooves in a barrel that you can then fill with a contrasting material.

If you can offset the track so it moves at an angle, you can make spear-point inlays.

If the jig does not move side-to-side, I can't think of anything I'd want to use it for (which is a limitation of my imagination, doesn't mean the jig useless!)

The carbide tools look they have been adapted for boring deep holes.

The speed controller was hooked to the trim router, the lathe is a jet variable speed.

trying to find the model and manual on the speed controller.

Not sure why he had it that way. The router just sits up there and may slide 1".
May have to look into inlaying like Duncan mentioned.

Ill have to take a look at the handles and see about the deep boring.
