Clausing 20 Drill Press #2276 - Need some help

[thinkracing]

I bought a really sweet Clausing 20 Drill Press Model 2276. It is overkill, but I was tired of cheap Chinese stuff and wanted a nice heavy American piece that would be the last drill press I ever buy and probably end up in my sons shop.

It came out of a machine shop in NY after they upgraded equipment. It is very clean.

I'm struggling with an issue related to getting it running. I did not get a manual with it, so I'm going off limited information I've gathered from the Internet.

My electrician came by today and installed the phase converter and wired it for 220V - it has a 220V plug. When I put it in low and turn it on, the drill does not turn, but oscillates right, left, right, left as if it is hung up.

I'm not sure if it is a belt issue, or a wiring issue.

Here are some pictures. All suggestions are welcome.

i cant help with your phase issue, but thats a bad *** drill press...

X2 on the nice drill, no expert here but I wouldn't use a static phase converter. What did the electrician say about it? The static converter will derate the DP by 2/3 I'm told.

How many hp is the DP? Any thought on a vfd?

Here's some good reading on static converters;

Not sure what you mean by this ?? Most 3 phase is 208 not 220. Or do you mean the phase converter is 220 ? If you turn the drill press on and give it a spin by hand will it keep running ? Are you certain that it is a 3 phase motor ? Do you have the means to check the voltage coming out of the pahse converter. It should be 208 volts across any pair of two wires. Can you show us how he wired it or is it all "hidden" ? How about a picture of the outlet without the plug in it ?

Sounds like a wiring issue?

 

[thinkracing]

I won't be able to answer all of the questions, because I simply don't know. The guy who helped me can do electrical work, but isnt a specialist. I'm going to call a guy tomorrow to measure the voltage coming out.

Here are some more photos based on the questions already asked. I appreciate the help. I'm certain I'll get it sorted with your help.

Here is a YouTube video of what it is doing also ...

From what I've read the static converter only starts the motor, it then runs on single phase power, the DP might not like that. I'd look for a 2 hp vfd and be done with it.

usually those converters will only start the low HP rating then the high rating is for additional motors, you are trying to start a 1-1/2 motor with a 1-3 phase converter. My suggestion would be to get a 1/2HP idler motor and start that first, then the phase converter can run up to 2-1/2HP along with the idler which should be OK for your drill. Since its a drill its not a heavy duty load otherwise you would have had to step up to a higher rated converter. I have a 10HP converter with a 5HP idler to run a 2HP mill.

nice drill though, wish I had a nice clausing...

That motor acts like it's single phasing. that means that it does not have power to all three motor windings, look for a wiring problem or a blown fuse or circuit beaker. Make sure that the control circuits are connected to the non manufactured leg of the input power.

tr,
First of all, even though a lot of guys dont like them and they are not as efficient as the rotary type, the static type of phase converter like you have should work just fine as long as it is properly sized, especially for a home type shop. I know of several complete machine shops that run every piece of thier equipment on those types of phase converters.

That being said, make sure that you call an electrician that is familiar with 3 phase and industrial type of work. Most residential electricians just dont see the stuff at all and might not be able to help you figure out what is wrong.

 

[thinkracing]

Thanks guys. I'll connect with an industrial electrician and keep the thread updated with progress.

I have the pretty close to the same drill press...When i got it, it was 3 phase, i took out the motor and took it to an electric motor shop, and he replaced it with a Baldor 1HP single phase, and it has ran great for the last 20 years...By the way, if you need parts, Clausing is still around...

I have to concur with Gorilla. Most likely you have the control relay connected to the manufactured leg. Trace out the wiring and make sure that the relay coil is powered all the times as it sounds like it is dropping out. If you don't want to trace take the three wires from the phase converter and move them one terminal to the right where they land on the drill press. The end wire moves to the far left.

The solution to date is to either go the route like what weaponizer suggested, or install a rotary phase converter. I ordered this product - http://www.temcoindustrialpower.com/products/Phase_Converters/PC0003.html - and once it arrives will have an industrial electrician install it and get me up and running.

It may be a few weeks before I know for certain, but I'll be sure to come back and post an update. Thanks for all of the help. I sent the electrician to this thread to help diagnose.

+1, Beautiful drill press.

Industrial electrian is key- it has to be a wiring problem, the motor is not energized on all 3 windings.

So I take it you did not try what I suggested?

On Edit, Look at item 6 in the install notes of the rotary you have linked to. You may have the same problem with it if you connect the generated leg to the control contactor. Been there done that.

Second edit http://www.phase-a-matic.com/PDF/SIS.pdf Item 6 here also says the same thing.

tr,
There is absolutely no reason the converter you have should not run that tool properly. If it is wired incorrectly, it will do the same thing no matter which phase converter you get You really should solve the problem first.

By the way, the one you ordered looks way too inexpensive. You definitely get what you pay for in this type of equipment.

Larry, Yes when I get home, I planned on looking at the wires as suggested.

Bill, I'm not disagreeing with you. I'm leaning on some advice that came to me from a source that came highly recommended. Admittedly I know very little about this topic.

I was told that this rotary converter will prolong the life of my drill, as well as make it run smoother and eliminate any risk of burning up the motor.
