I want reverse on my drill press

[Fluxion]

Like the title says, I want reverse on my drill press. I have wanted to use left hand drill bits several times now and reverse might be handy other times. The motor data plate doesn't say it can be reversed but I wonder if it can be? I have other motors that can be reversed by switching the T5 and T8 wires, can anybody confirm this?



Any help would be greatly appreciated!

That motor does not have the leads for reversing it. You would need to access the start winding and solder in your own leads if you want to reverse it. I've done it, but it is time consuming. Likely easier for you to replace the motor.

0r go to a DC motor and controller.

I'm trying to understand this. I have wired up a few motors, most have instructions on the plate for reversing. I have two pics below, both of motors that can be reversed. I don't see reversing leads listed on either of them, so what's the difference? I'm not trying to argue here, I just want to understand why the motor I have cannot be reversed. If all else fails I do have a couple other motors that would fit.

You need a reversible motor like the one that came on my Dayton/Grainger drill press (and was NOT wired for reverse when I got it). The switch was smashed and had to be replaced, so I wired in a drum switch and I think it took seven wires between the drum switch and the motor to make it happen. Also took me an afternoon of pondering and looking at motor and switch wiring diagrams to come up with the wiring diagram to use.

I won't repost all of the pics I posted, but here is a thread on this.

Or you can do like my old Gilson rototiller does for reverse, and do a figure 8 with the belt.

I'd try switching the T5 and T8 and see what happens. More likely the motor can be reversed, but since it was made for that specific app, there was no need to show how to reverse it, versus the other motors you show, where depending on where they were used, might need to be reversed.

Reverse is handy for tapping as well. Try the 5 and 8 interchange.
I did mine with relays, I have a double foot pedal where one pedal is forward and one is reverse.

but since I'm cautious with electricity, I'd check t5 and t8 with a ohm meter to verify it is the start winding. It will have a higher resistance than the motor windings. Before applying power.

Post a pic of the connection plate.

I agree that the manufacturer probably skipped the jumper lugs since this motor was intended for a DP. Can you post an image of the internal connectors?

There's very little you can do to damage an electric motor if you jumper it wrong for just a few seconds. Just make sure the case is grounded and you're using a GFI outlet with a circuit breaker.

I've had to figure out wiring on lots of motors where the diagram was illegible or unavailable.

I thought I would update this thread just in case someone else has a similar question.

A couple weeks ago I finally got around to wiring my drill press for reverse. Just as I suspected, swapping the T5 and T8 wires reversed the motor. I changed out the front switch plate and installed a SPST toggle switch for the power and a DPDT toggle switch for forward and reverse. My vinyl cut labels are already damaged so I might redo that someday, maybe not.

Works great! I had a few holes to drill and tap 1/4"-20 in some Mic6 Aluminum and the reverse made the tapping easy.

How fast were you rigid power tapping in that thing?

The slowest speed, 450rpm I think. The Mic6 was only a half inch thick, a through hole and I used a spiral point tap. I tried it on some 1/4 steel and worked good there too.

Well done, nice job.

Consider a foot switch for on off, it allows both hands to control the tapping.

Just put the belt on backwards. :tard:

Are you sure you can't just buy an Australian belt and put it on the same way?

Ah, the Simpsons...convincing Americans for years that Australia is opposite of America (late 90s episode of Bart going to Australia due to a prank phone call and flushing the toilet only to find that it runs the opposite way due to the Coriolis effect which btw only affects air currents not water).

For tapping you can also use a tapmatic. It reverses when you push the handle up. The spindle never stops and no need to rewire.

A foot switch is a good idea.

My wife is Australian, maybe it would run in reverse if she used it?

I would love to have a tapmatic, someday I'll get one.

Yes you could do this BUT you lose warranty time due to the belt crossing the date line.

tapping head is the ONLY way to go.......

read the instructions for setting the torque clutch set it and go
