$20 power slotter for my lathe!
John Hill:
$20 slotter and maybe gear cutter!
Hmmm... 20 NZ bux must be about 7 quid! :scratch:
This little chinese drill press was too cheap to ignore at about $20 and it has been resting it its box while I decided what it might be useful for.
First step, mount it on the cross slide of my 12x36 lathe.
The orginal base has been replaced by a turned plate and a support fashioned to hold a ball bearing in line with the spindle of the drill.
A spindle is mounted in the chuck with the other end in the bearing. A simple cross drilling and a set screw form a simple tool holder for 6mm tool steel. As you can see it cuts a nice slot in the end of this piece.
The next step is to make an indexer for the lathe spindle and fortunately I have a set of Hercus lathe change gears on hand that can be pressed into service. The change gears are not Chinese but they do appear to be of adequate quality.
Dean W:
That's an interesting setup, John. It looks like it has a number of possibilities. Along with maybe gear cutting, long keyways should be workable too.
"The change gears are not Chinese but they do appear to be of adequate quality."
Now, that's funny! Save your money, and one day, you too can have a set of plastic lathe gears!

{A couple of days later!}
I have made an indexer to go with the vertical spindle:-
I made a pile of bits...
...which put together look like this..
...the aluminium bit screws into the end of the spindle and the small hole goes over the stud that secures the gear case cover..
One detail which you cannot see is that I added a nut on the gear cover stud inside so that the knurled knob has something secure to screw down on to, not just the springy fibreglass cover.
Now I should be able to cut a few gears!
Bernd:
Boy, talk about a simple solution. Nice design John. :thumbup:
