A conscientious QC inspector like Ginger is vital to shop operations.

[@LouJustlou]

My shop cat Echo provides "cat scans" of my work on a regular basis. Nice to have the pro feline opinion. 😊

[@phlodel]

I haven't seen Mary Ann in a while. I hope she's OK.

[@jamesdavis8021]

I have a permanent shop cat and,a occasional shop dog

[@Bob_Adkins]

Did you see her reaction to the sharp, non-Monarch corners on the riser plate? She didn't like it!

[@plakor6133]

Especially the ubiquitous kitty backside.

[@Farm_fab]

Ginger is absolutely confident in Keith's work, with only a passing glance.

[@truckguy6666]

You slip these inspectors a chicken or catnip Temptation's every once in a while and you'll be amazed at what they'll turn a blind eye to.

[@don4364]

Keith, I am so glad to see the 1" carbide end mill being used. I paid a whopping price of $1.00 for it. I knew you would have a holder to put it to use. I see you used a rag to hold it being as it is razor sharp, and does a great job milling your tail stock base. As always, great content. Thank you. Don

A good episode with lots of useful info and content. Best wishes for 2024.

[@DolezalPetr]

Also under heavy load the tailstock center bends down a bit so it is better to have the tailstock center a bit high.

[@siggyincr7447]

Actually under a heavy cut the work piece will push up on the center as the work piece tries to ride up on the cutting tool.

[@wrstew1272]

Absolutely love the “no measure “ method of aligning! TLBR system- that looks about right. No prints, center finder, digital map, just do it 😂. Only critique is that a round over on the outboard edges will prevent blood stains on your machine in the future 😮…. Enjoyed the process as usual, looking forward to seeing chips flying, the colors are amazing!

[@edwinfriedl2446]

Now a storage place for the crank when not in use. Always something else I can find for someone else's to do list LOL

[@DumahBrazorf]

Ginger (safety inspector) is always worried when there's some modifications to machinery.

[@haydenc2742]

Before you paint it...take a needle scaler to that block and dimple the snot out of the surface to make it "matchish" the cast look, maybe even do some round chamfering on the edges Very cool addon/modification! Keep em coming!!!!

[@MartsGarage]

Nice job, Keith. The big Monarch will be a great asset to the workshop.

[@JohnBysinger]

Keith, im always impressed with just how much you get done on each episode. You take on these very large projects (like the Diresta bandsaw), and im never disappointed with the progress we get to watch and the results we see. This tailstock i think has been a great example for people to see that restoration isnt always a game of exacts, but rather one of creative solutions. Plus we get to see real challenges solved with real machine tools. Whether its the upcoming castings for under the ways, or machining your 1" spacer and its land on the bottom of the tailstock, you always put together great demonstrations of machinist solutions to shop challenges. I really meant it when i said never disappointed!

[@gregwitkamp5583]

Nice job there Keith retro fitting that tail stock

[@aserta]

I was about to do the same to my biggest lathe, but i saw a video from the guys at Festo and had the idea to put an air feed to the thing and it worked. I can push the tailstock with a finger when the line's activated. It's a bit of a hassle cause i have it shoot some oil as well every time, but it's worth it on account on that ease of use. Before hand, i even strained my back once trying to push that behemoth. That said, Keith here's to a fruitful 2024 and good tidings to you and yours!!!

[@rexmyers991]

So impressed how you can visualized the end product (result) and then do the steps to create it. Very nice result. It looks like what the Monarch people would have done. 36:08 36:08

[@infoanorexic]

That is a feature I wish I had on mine, it is right at the breakover point of "nice to have" and "must have." Ginger must have had his turn with the orange cat brain cell that day 🙂. They really are smarter than most would give them credit for, and they can be real sweethearts ... or really conniving, like the one that is currently giving me the gargoyle treatment because I haven't filled the feed dish yet ... Dad would say "He isn't stupid, he's just smart enough to make you think he is." Looking forward to finally seeing this lathe in action.

[@Daniel_cheems]

Very nice mod and Happy New Year! Please don't forget to make a new pinion gear for the rapid traverse attachment!

[@Hoaxer51]

It would be a good time to do it while it’s fresh in your mind, it would also finish everything up on his rapid traverse attachment. Besides, everyone likes a gear making video. Lol

[@TheUncleRuckus]

Awe... Ginger The Safety Officer had to come inspect that you were following safety protocol. 😂

[@tropifiori]

A nice restoration

[@jensschroder8214]

Happy New Year!

[@mathewritchie]

Anyone want odds on the correct tailstock turning up once this one is complete?

[@peterhobson3262]

Of course that'll happen. I misplaced my favorite tap wrench, tore the shop apart looking for it, bought a replacement, and when I was putting the new one away in a drawer I opened the wrong drawer by mistake and you all know what I found.

[@mikewatson4644]

@@peterhobson3262 Best way to find a lost tool is to buy a replacement. Voice of experience

[@carlbyington5185]

Great job Brother !!

[@nrml76]

It would have been nice if you had rounded the edges of the adapter block on the belt sander and textured it with a quick sand blasting to make it blend in more aesthetically with the rest of the machine.

[@JohnBysinger]

Good suggestion, he does plan to replace that center bolt with a socket head cap screw, would be a good time to do that.

[@Bob_Adkins]

The cat noticed it, and tried to bring it to Keith's attention. It can still be fixed on a rainy day.

[@richtes]

Looks like the spacer just fit inside the milled flat. Thought he was going to match it to the cutout. Cat didn’t seem to approve either

[@mechanicalTurk0]

And if he ever wants to make a replacement he'll have to pick up his eyeballed hole pattern instead of having some regular numbers to hit.

[@StevenHess]

Happy New Year to Vintage Machinery and Keitrh.

[@danielcobbins8861]

Happy New Year, Keith!

[@warrenjones744]

The M and CM series lathes from the 40's used that same style tail stock as what you have there from what little I know of them. (I have a CM 20 with a factory cast 30" swing). From 1200 miles away it looks damn near identical. I suspect they used many common parts over the years on newer different models. Anyway looks like you will have a nice functioning tail stock no matter what flavor of lathe it came from. Cheers

[@Hoaxer51]

Everything looks good from 1200 miles away! Lol. Happy New Years!🎉

[@JohnBysinger]

They probably got several decades out of the casting molds for them, likely just machining more or less to match the swing of the particular model?

[@paulsilva3346]

23:00, Keith, I see a need for a 5/8" Shoulder Cap Machine Screw, through the block. TAPPED INTO THE TAILSTOCK FOR maximum strength..? Lookin good, so far, Happy 2024 to you, and yours 😊 23:43

[@tsmartin]

That bolt isn't carrying that much of a load so "maximum strength" isn't required.

[@guypehaim1080]

Hand drill guides are available which allow you to drill perfectly perpendicular holes.

[@bcbloc02]

Looking great! It will be a treat to here that beast coming up to speed and munching some chips.

[@F1DesignUS]

That is impressive. I am doing similar on a much smaller lathe and this really inspires!

Wow, full send. I like it,New parts from old parts that don’t fit together. Thanks for sharing, very useful information and technique.

[@oldfister7460]

I think you might want to use a reamer on the end mill, it looked a little rough on my large screen tv. I really appreciate your video's.

[@edsmachine93]

Another outstanding job Keith. Everything came out very nice. Happy New Year to you and your family. Have a great day. Happy New Year Everyone. May all of your days Blessed in the New Year.

[@truckguy6666]

Hypothesis: if he goes to scrape in the turcite, the inital bluing print will show heavy contact on the innermost length of the flat ways. This due to the Vee way being sloped where the turcite is applied and the turcite lifting that side of the tailstock slightly less.. then again the epoxy may have negated all of that, in fact potentially automatically fixing any deviation in flatness... things that make you go hmmm.

Great adaption Keith; however, I think the spacer block would look a lot better if you'd "ease" the corners and outside edges. Everything else on the lathe has rounded edges.

[@Hoaxer51]

He’ll have to charge extra for that, I think he’s trying to keep this a low cost addition. Lol

23:00 Going back a couple of centuries to the 'good ol' days when no-one cared about interchangeable parts. Not a criticism, btw, I have done the same thing myself! 33:50 Well done, Keith! For all my previous nervousness about using Turcite, you've proven me wrong. I wouldn't accept this amount of misalignment on a watchmaker's lathe, but on a big boy it will do just fine. Happy New Year to Keith & all his loyal followers/subscribers.

[@oleran4569]

Looks good Mr. Keith! That must be part # KRM 010124 (Keith Rucker Mod +date) 🙂 Happy New Year to you!

[@jeraldware1518]

Did you consider maching your clamp base rather than having new cast? Is there a brass bushing(?) on the front of the tailstock at the spindle? Is itnused for alignment? Thank you

[@mrcamelpmw]

12:27 The eye of the tiger

[@TheJohndeere466]

Those brackets are usually mounted clear at the right side of the tailstock. The way you are mounting it, the carriage will hit that bracket when trying machine a shaft.

Looks like the supervisor approves.
