Question about drill press/jig setup
« on: January 19, 2008, 02:49:40 PM »
I have a question about jigs in general as they relate to drills.

Do I need two things: Drill and jig, or...

Do I need three things: Drill, jig and table that can move left, right, forward and backward?

Reason I ask is that my brain can't understand how pitches are drilled if the jig is immovable, and the only inexpensive jigs I've seen for drill presses look like they hard-mount to the drill press plate. In that scenario, with the ball centered under the bit, you'd only be able to drill zero pitches, correct?

You need some sort of XY table to move the jig.  Most jigs, like Rudel, have built in XY capability.  Jigs that can't move are designed for mounting on a mill with a built in XY table.

Jess,

Both set ups are available.  Your better set ups are a jig that is not movable mounted to a milling table or milling machine.  The machine moves, not the jig.

The older style "Rodell" type set ups had a stationary machine.  The jig moved slightly along the X and Y axis.  If you are not doing this for a living, this is probably the way to go money wise.

If you are going to pro shop for a living, get a milling machine set up, it is waaayyy better.  It costs waaayyy more too, but worth the money IMO.

Hope this helps ya...

Thanks. This told me exactly what I needed to know.

There's a jig for sale on eBay that came off someone's milling machine and I thought I might bid on it. Then in the middle of practicing tonight, all of a sudden it popped in my head, "Waitaminute, how am I going to drill pitches?"

It bugged me all through practice and then dinner, too. (g)
