Keith, if you are interested in it, I have a 21" 4-jaw steel body chuck here that has a D1-8" back I'll be more than glad to donate to VM. I don't believe the chuck has ever been used. Let me know, Ken

[@Hoaxer51]

Very generous, hopefully something works out. Merry Christmas!

[@VintageMachinery]

Please send me an email and we can discuss. I show my email address at the beginning of each video when my name pops up on the screen. Thank you!

[@4GSR]

Email sent. Thanks, Ken@@VintageMachinery

[@glennanderson4440]

Very generous, but a 612 is a D1-6, at least mine is.

[@4GSR]

That's what Keth said. I'm very surprised that large Monarch only has a D1-6 mount. I tried. Ken@@glennanderson4440

I suspect after this video is aired. Someone will have the exact tail stock you need.😅 I’d know that. It will be Marry Christmas to you.

[@ifitsrusteditsmine]

Thank you Keith for so many hours of entertainment. Merry Xmas to you.

[@michaelscott8226]

Happy to see the 612 getting towards completion. Honestly, I half expected it to leave the shop, as it wasn't being used at all. Keith's Home for Wayward Cast Iron Machine Tools is the place where manual machines go to live again! Can't wait to see your ultimate solution to the height and base clamp issues. Merry Christmas to you and your family as well as to all of your subscribers and Patrons!

Been away from the channel for a while...imagine my surprise to come back and find 2/3 of a Keith Rucker left! Seriously, happy to see you looking healthy and breathing normally. Good job! Have a great holiday, and stay well...

[@MrClickbang357]

Good to see you got the tapered shaft out and it fit the other tailstock like a glove! Can't wait for pt 3!!!

[@CameronMcCreary]

Nice find Keith. When working with older machines, sometimes one has to be prepared to re-build certain parts. Merry Christmas to you and your family.

[@philipmackin1025]

If it's worth it I wonder if Keith will refurbish the live centre quill? Too bad the large end-stock doesn't split between the base and top like the small one does. That would be much easier to add a shim between the base and top. Come to think of it, in my mind, refurbish both end-stocks.

[@elsdp-4560]

Thank you for sharing.👍

[@WeTrudgeOn]

I've found that a needle scaler does a great job of cleaning castings. It leaves a sandblast like finish.

[@mikeycoop66]

I am very happy to the large Monarch getting some love. It was the first lathe in the shop and had definitely gotten lost amongst everything else. It will be even better to see that thing making chips and working as intended again.

[@MrChevelle83]

i sent keith those 4 plates for the press. its great seeing them get put to use!!

[@Hoaxer51]

I remember when you sent those, you said something about them being drops maybe from where you work. It’s been awhile ago so I’m probably off base a ways son the back story but what you donated sure seems to be very helpful. Thanks for sharing!

@@Hoaxer51 yes you are correct!

[@dalebennett5227]

Merry Christmas

[@bcbloc02]

Great to have parts on hand!

[@russkepler]

Like others i would suggest shimming between the top casting and bottom casting for height (after scraping the base to the bed and to level). Turcite will just make the tailstock too slippery on the bed. There are materials similar to Turcite used to fill gouges in the bed if you want to use a fill material but I am unsure of using it to cover the entire base bottom.

[@billbryant7194]

Yes, that is where I would have expected the shimming to go. Putting in the ways would expose it to wear and the need to replace it at some point in the future.

[@user3141592635]

I think that as well.

[@Bob_Adkins]

@@billbryant7194 I thought of the same way to shim it, but either way is good because Turcite lasts a very long time.

[@johnspathonis1078]

Agreed. Also this would allow shims to correct any out-of-parallel between the quill axis and the headstock axis in the vertical plane. Correction is also required in the horizontal plane.

[@russkepler]

@@johnspathonis1078 what is usually suggested is to scrape the tailstock base level with the lathe bed both ways. That let's you simply shim across the top of the base to get the quill on the spindle axis height. You don't want any gaps in the shim due as the clamping forces holding the top down would distort the top when you clamped the tailstock to the lathe ways. When I scraped in the tailstock on my Monarch it took a .006" shim to get the quill back up to the spindle height.

[@jacilynns6330]

I’d split the tailstock from base and make a shim between base and tailstock on surface grinder. I’d also take a reamer to that quill as it is probably abused and rusted.

[@johnlee8231]

Was afraid when you picked up that tailstock without the clamping bolts in there that the base was going to come apart from the top casting. On my smaller tailstock thats what holds them together except for the side to side adjustment bolts that just push on the casting. So glad that wasn't the case.

[@user-di7ky2mk6s]

The reason most goals are not achieved is that we spend our time doing second things first.

[@componenx]

If I had been interchanging the two quills, the diameter, thread pitch, or something else would have been wrong! I'm glad that wasn't the case here.

[@whalley6044]

Merry Christmas! I was wondering about the purpose of the shims on the plug in the back. I'd check if the key was trapezoidal rather than square & the shims were to set the clearance to control rotational slop in the quill. I.e may need different shims for different quill. Don't know why they'd do this but don't see another reason for the shims. Rather than shimming the tailstock height you could get Clark to cast you one & machine it to fit - be a neat project for us to watch.😊

Don't scrap the castings, send them back to monarch so they can refurb them and keep them in circulation and keep the company going for machine support. Although they're expensive it's good to keep the company around for support

The tailstock lead screw with the morse taper quill had an ejector rod on the end. Pretty sure the permanent center one doesn't have one and you are probably going to want that.Bet the original screw won't fit the right hand drive.

Would have been interesting to watch you turn that built in center into a morris taper.

[@richb419]

Hi Keith, it maybe a good idea to protect the lathe bed when you are working over it. isn't Turcite material a light load material, doesn't seem the best stuff for the tail stock adjustment. Merry Christmas to you and yours

[@jeffanderson4979]

I bet with the weight loss your sleep apnea may be a thing of the past?? I grew out of mine after weight loss. Let’s hope! Love your videos

[@tomswindler64]

Cool 😎😎😎👍👍👍

[@kindablue1959]

Seems there should be an official designed-in way to adjust the tailstock height - that's something that would be part of routine maintenance to adjust over time for high precision work.

[@oldschool1993]

The clamshell lock is 2 pieces, the bottom half is threaded so when you tighten the handle it squeezes the 2 halves together. After removing the top part, all you had to do was tap the lower half downward to break it free of the quill.

[@ianpendlebury3704]

Exactly.... I was shouting at the screen. Anyhow he got it done.

[@oldschool1993]

@@ianpendlebury3704 We didn't get a clear view of the clamp side of the quill, but I suspect there was a pretty good scratch where the quill was pressed past that rusted in lock.

[@russkepler]

That lock is called a "split cotter", or it used to be called that anyway. It used to be a common way of locking a cylinder in a housing with minimal movement on locking.

[@chrissmith513]

[@alanglen5902]

I imagine you need a metal shim to raise the tailstock. Otherwise the clamping bolts will compress a non metallic shim, and the tailstock will drop with use. What do you think???

[@ml50486965]

marvelous work! But how are the shop cats doing?

[@JohnfromEngland]

Keith have you got two dead centres and a bar that you use to set the run out of the turning between centres You should be able to use that to precisely mean sure the difference in heights but clocking over the TOP

[@gus9675]

Keith, Ever consider glass beading instead of wire wheeling the more precision parts? Merry Christmas!

[@thunderstruck1078]

I can't figure out who would want a fixed center in their tailstock. Who would want a lathe without an ability to use a drill or a boring bar in his tailstock. There has got to be a way of exchanging the tooling. Maybe it just screws in. I guess that's not important any more. Great job combining the two tailstocks into one.

[@royreynolds108]

The fixed center was probably off of a lathe that was dedicated to making a part or a production process.

[@greeceuranusputin]

And on the next episode of This Old Lathe...

[@lecnac855]

I surface grind my shims then scrape them in.

[@donbyers1448]

When the tail stock adjusting quill screw was unthreaded from your morse taper quill, it had a lot of corrosion on the threads. Would it be beneficial to clean the internal threads on the morse taper quill?

[@kennyronful]

Did you check the existing tailstock paint for lead before using the wire wheel to remove it? I would suggest using a particle mast when doing this type of operation, just in case.

[@williammurfin6354]

Merry Christmas Keith, family. Just wondering if with the shaft you swapped out, as it has screw in end that looks to hold that purpose built end for it could you make a another insert that has the right Morse taper end in it??? I understand that's a lot of work but could it be done????

[@kindablue1959]

I noticed that, but it doesn't have the access hole on the side that is needed to wedge out tapered spindles.

[@ruben_balea]

It's relatively easy to Make a morse taper hole, you only need to make something closer and then finish it with a Morse taper reamer, but it's even easier to swap the quill if you already have the proper one 😉

[@kindablue1959]

@@ruben_balea Sure, you can make *anything* with enough work. But my main point was that it was obviously not designed to be swappable with a morse taper center.

[@ruben_balea]

@@kindablue1959 I didn't mean that it was designed to be swappable, only that the modifications are easy to make for someone who already has other lathes and milling machines.

[@JaapGrootveld]

A shimed up tailstock, Hmm...alignment problem comming up. No problem. Keith will tell us its alright when it's done, without a smile on his face and we act as if he done a good job.

[@jrb_sland]

I'd be concerned that an overly-casual shimming operation to lift the tailstock will fail - you'll have no easy way to adjust the centering up/down, which might[?] be troublesome in a similar fashion to the left-right centering necessary for correcting subtle taper cutting? Admittedly the usual cutting tool position up/down would take care of a small error, but... Perhaps this is just my tendency to OCD kicking in?

[@number2664]

Turcite on the tailstock I have heard bad things about. Being slippery it makes it hard to clamp the tailstock down and it may slip under thrust.

[@Ropetangler]

I have heard similar comments, perhaps brass would be more suitable.

[@number2664]

@@Ropetangler i recently pulled apart a DSG lathe that had brass/ bronze liners underneath the saddle. But they were not solid pieces but more like bronze lined steel liners.

[@bloodknottrevelian3396]

I noticed on the quill that you didn’t use that the centre was retained by a screwed ring. If you were to unscrew that ring would it then reveal a Morse taper behind the centre?

[@thunderstruck1078]

Is the tailstock casting all once piece or two pieces? Instead of shimming it at the bottom perhaps you could do it between the castings, assuming the casting is in two pieces.

[@thundergut6539]

Is there a playlist for this lathe restoration?
