Topic tags/keywords: delta quill lathe 46-715

I have a bad Quill in the tailstock, I need to remove it and order a new one.
It will come out to the 3” mark and move in to the 1” mark. It takes 2 people to get it to move this much.
I think it should keep on coming out to be removed?

Have any of you done this? How do you remove the quill?
Thanks

I have had the morse taper stick once, but the quill should move the entire distance if there is nothing in the taper. Locking screws on the quill? The crank unscrews from the lead screw in order to remove the quill. Left hand threads? Don’t forget the set screw.

Got pictures?

Thanks. Yeah I got all that done. No problem with any thing in the MT#2, locking screw, set screw.

I can remove every part off the tailstock but the Quill and the key.

Basically I’m asking does the quill come out the front or back when fully removing it? I need to know what way to hit it the a %#^ BIGGER HAMMER!

Just a WAG, but I would say it comes out the front (toward the headstock).

Here’s a parts breakdown. Looks like it should come out the front. If it takes two people to move it sounds like it already got hit too much with a hammer.

Thanks but I guess no one has done this.
I should say I know how to work a lathe and how a quill works. But like a car I can repair a lot of things, I can work the transmission but I have never removed it. YET.

I have looked over the parts Diagram and the worthless manual for hours, no real help, Yes the dotted line shows from the front.

“If it takes two people to move it sounds like it already got hit too much with a hammer.” You never know! I just got it used and abused from a High School.

Still, it just might be worth taking it to a contracted Delta Service Center, even if it cost you a few $$$. Mine was under warranty, but well worth the trip regardless. That is unless you are prepared to purchase an entirely new tail stock.

FWIW, and I had already beat it up with a hammer.

Don’t have that lathe, but when that happened to me on my old Delta. Took it apart from the rear starting with hand wheel, sprayed WD-40 with little twisting & turning everything came apart. Cleaned everything & put it back together. Not sure what caused things to jam up, once cleaned and put back together never happen again.

Sometimes the teeniest little tad of swarf or dust chippings wedged into the quill housing can cause the whole sheebang to sieze up.Taking it all apart and checking for roughness or dust and cleaning, if it is just dust or chipping.Then oiling and putting it all back together can very often work miracles.

There should be a groove on the bottom side of the quill. The groove might accomodates a roll pin, or some other protrusion located in the tailstock to keep the qiill from turning. If the groove is boogered, or the roll pin, the quill might have turned a little and is binding on said pin. Check the groove and see if it’s vertical with the center of the quill hole. If not, get it vertical, and remove the quill, and replace the pin….... Jerry (in Tucson)

I got it out. With the tailstock in a vise, turning the wheel clockwise with both hands (taking a lot of work a real lot) for about 10 mins I got the Quill back to 3” out. Then disassembled the wheel, plate and Spindle Screw (just the tailstock and quill remaining) knocked out the Quill out the front with a wood dowel and a 2lb dead blow hammer.

Since no one was done this or was had a quill so damaged and stuck so hard in the tailstock, I will do a photo blog posting. Btw I repaired it and it’s working fine.

P.S. Jerry good info, but that isn’t the description of a 46-715. The groove is at 9 o’clock not 6, no roll pin but a key (Delta term “Quill Scale”)

Ok, so I was off a little, and I couldn’t come up with the clock positions. Getting old sucks. Hehe So, what was the problem???
I mentioned the roll pin because of my old Delta. It has a roll pin and groove that finally wore the edges of the groove, and the roll pin pushed down a little causing the quill to turn and locked up similar to your description. ........... Jerry (in Tucson)
