Clausing 4914

AR
I HAVE A CLAUSING 2914 MYSELF. I CHANGED MY LATHE TO VARIABLE SPEED USING A HUNANG VFD. IT TOOK ME A LONG TIME TO GET THE 1 HP MOTOR RUNNING WITH THE VFD BUT I DID. I MOUNTED A 4 BUTTON REMOTE CONTROL ON THE LATHE. I RAN CAT 6 FROM THE VFD TO THE REMOTE. I COVERED THE WIRE WITH COPPER TAPE I GOT OFF EBAY FOR SHIELDING. I RAN # A WIRE, I HAD, THROUGH SEAL TEIGHT CONDUIT AND WIRED THE MOTOR TO THE VFD. THE CONTROL WIRING WAS ALSON RUN THROUGH SEAL TIGHT CONDUIT, 1/2 INCH. I DROVE A GROUND ROD IN THE GROUND THROUGH A HOLE IN THE GARAGE FLOOR AND GROUNDED MY LATHE. THE HARD PART WAS THE PROGRAMMING. SO FAR I HAVE IT RUNNING IN FOWARD AND REVERSE AND CONTROLLING THE SPEED WITH A SPEED POD.
I DID NOT READ HOW YOU WERE RUNNING YOUR CLAUSING LATHE BUT IF YOU WANT ALL THE DIRECTIONS AND EQUIPMENT REQUIRED FOR CHANGING YOUR LATHE TO VARIABLE SPEED, LET ME KNOW. I HAVE THE PROGRAM WROTE DOWN FOR THE HUNANG VFD TO RUN YOUR LATHE. I CAN EMAIL YOU WITH IF YOU HAVE NOT GIVE UP ON YOUR LATHE.

MY CLAUSING LATHE COST 2200.00 DOLLARS. IT HAD ALL THE TOOLING ON IT. IT HAD A THREE JAW CHUCK AND A STANDARD SQUARE TOOL HOLDER. I CHANGED IT TO A QUICK CHANGE TOOL POST AND HOLDERS.
I AM NOT AS GOOD AT WELDING AND WORKING ON REBUILDING A LATHE AS YOU ARE SO I WENT FOR THE HIGHER COST MACHINE. IT CAN BE SEEN ON YOUTUBE UNDER CLAUSING 4914 VIDEO.

DO YOU STILL HAVE YOUR CLAUSING 4913 LATHE AND HAVE YOU MADE ANY THING ON IT YET? I AM A MACHINIST BUT ONLY MAKE THINGS IN MY SHOP AS A HOBBY. I LIKE TO HEAR FROM THOSE WHO HAVE THE SAME EQUIPMENT AS I DO. IF YOU KNOW OF ANY SITES THAT HAVE GOOD REBUILD OR PROJECTS LET ME KNOW.

THANKS AND GOOD LUCK WITH YOUR LATHE

Thanks Ken. The bull gear pin was stuck. I had been spraying it with PB blaster thinking it was stuck. After I read your post, I went out and levered it gently with a screwdriver and it popped right out. I was then able to engage the back gear and get the spindle to move.

It doesn't say it in the manual, but I'd imagine that actually comes in handy when you want to lock the spindle if you need to get off a stuck chuck?
I have read that is a no-no because you can break a gear tooth. But I have used that method in general practice (Not a "stuck" chuch however)

I've got the motor out now and hooked up to the VFD in my workshop. Using what you told me about the drum switch I was able to hook it up as the forward neutral reverse controlling the VFD and motor. You were right, once I had everything in front of me it was a piece of cake. Thanks again! And go ahead and call me a dork for saying this but this VFD is pretty freakin cool.
Yes, they are pretty freakin' cool!

I have a huge Delta abrasive metal chop saw I picked up on eBay ages ago. It's still in my mom's basement. It has a massive 3 phase motor. I had thought I'd get rid of the thing because it would be too much trouble to run. Now I'm thinking a VFD hooked up to it would be great, you could even slow it down enough to run it as a cold saw. Too bad I don't have any room for it. hmmm...

Anyway, the tool post slide and the compound slide are pretty buggered up. As I was aware the tool post slide is welded on both sides indicating it had been broken at some time. In addition to that, the compound slide has a pin inserted into the end of it limiting it's travel. As far as I can tell it's also limiting me from taking the whole thing apart. I can't imagine why someone would put the pin there. The slide end, where it is inserted, is pretty chewy. Do you think it would be ok to carefully cut this pin off with a cut off disk? Then file it down flush the way it should be?
Yeah, I don't see why that is there. maybe a little heat on it and you could pull it out? The proper "limit" is a screw in the end of the dovetail with a washer on it.

Also I can't tell from the exploded diagram but is the compound screw supposed to be two pieces? It looks to me like it was also broken at some point. The acme screw was held onto the rest of the shaft with a flat head brass screw and nut that do not look original at all. Also where the shaft attaches to the acme screw looks like it was welded on.
I can't remember exactly. In this picture-the screw on the left-just in front of the gear looks like a pin. I did not take this apart.

Another thing I noticed is that the tail stock handle was broken, and re-welded as well. I'm starting to wonder how bad this thing is. I think the main thing is, the ways are in good shape and the spindles in great shape too. Everything else I can fix.

To answer your question, this thing is so nasty I think it's going to take a complete tear down just to get it clean, and if I have it completely apart I might as well do a full on restore. I'm actually surprised how much I've got done in just one day. Of course it's always much easier taking it apart than putting back together.

By the way, how much paint did it take to do your machine? Is the TSC light ford gray almost white? It looks that way in your photos. Did you use the catalyst hardener with that paint? Did you brush it on, spray or both?
I think I used 1 quart, possibly 2. I would not say almost white, I think the flash makes it look whiter than it is. I did use the hardener on the big parts. I used mostly a small foam roller since it was winter and I could not spray outside.

Very nice looking 4914 I also have the same lathe and tore down, repaired and painted mine white. I didn't use hardener and am getting oil stains on the white painted surfaces. Oh well, it is a lathe that i use almost daily so what can I expect.
The 4914 is sure a sweet machine in my book.
 
I'm also the proud owner of a 4914. Great gear head lathe and is very accurate. I rented a trailer from u-haul and used 3 straps to secure it during an hours drive home. It rode well and like you used a 2 ton engine hoist to unload it and move it into the shop. Not a big deal, but it would have been much easier with a 2nd person to help. Mine came with a 1hp 220 motor that I replaced with a harbor freight 2hp motor for 120 or240 volt. Works great and no issues. I don't have 240 in my garage so this works just fine and much cheaper than having to buy a vfd or anything else.
Look on e-bay or amazon for chucks and backing plates. I have bought everything for tooling as well as backing plates from those sights, and it's the same quality for much less than many of the machinery websites. I just purchased a shars 6 inch 3 jaw chuck made by shars for less than 120.00 and it's a great chuck. I've got 0 run-out when measured at the chuck and at the tail stock after turning. Can't beat that. Yes our backing plates are hard to find because of the thread count and diameter, about 70.00 dollars, but what can you do?
l Hope you get your lathe home and enjoy yours as much as I do mine.
