Lathe Taper Attachment Disassembly: Monarch Lathe Restoration - Part 33

[@machintelligence]

Uh Oh! You said the four words that blow the restoration budget: "While we're at it."

[@Uncleroger1225]

Good Job as always Keith, Simple, entertaining, informative. I can't begin to tell you and the other U-Tubers how much I have learned from you-all, Thanks!!

[@bcbloc02]

Getting closer all the time!

Keith, this is my first time visiting your channel and you hooked me. Liked & Subscribed!

Hi Keith - Happiness is having a Monarch to play with.

[@richb313]

That Taper Attachment did come apart pretty easily which only means that the Assembly and Alignment will be a challenge. Look forward to that part.

[@unclebobsbees4899]

Richb313, brother isn't that always the way. Easy apart, grizzly bear to put together.

[@richb313]

@@unclebobsbees4899 You seem to speak as one who has practical experience in this area.

Oh yeah, aircraft mechanic who does a lot of car rebuilds. The aircraft usually go back together easily so no worries there! Lol.

Another fascinating entry Keith! I am a little sorry that I am up to date with the series--I want to click 'next' and get down to the reassembly stage right away!!! One area I would appreciate a little more detail on is the clearing of the oil lines. That is a real task and every tip or trick you can give there is very welcome indeed. My father struggled a great deal with the internal oil lines on the injection machines he was employed to maintain--along with a hundred other tasks that were his responsibility in the factory. Admittedly the owner had bought them for scrap and then expected him to get them running like new again... Not an easy task at all--not least because for some reason the prior factory had cut away small sections from every pipe. I recall it took him months to get them all unblocked, replumbed and running half way smoothly. What made it worse; he was never given the time to strip them down. They had to be running at full output all through the day and then any work my father needed to do to them had to be carried out after knocking off time. Definitely hard grind.

Nice to be back for the Monarch Keith. The build thus far has been great to follow along with and we are sure this taper attachment will be equally as well a joy to watch to learn and to share some thoughts about s well. WOW the whole thing is a bearing ride mechanism we think looks neat. We always replace bearings in all rebuilds, it is our method no mater what you see with the eye. Nice you are replacing all of these bearings we have never seen the inside of a taper attachment for a lathe. BOY the Internet sure has a lot on this currently still used taper attachment for the lathe. No rust where we live in the desert, thank you for the share, Lance & Patrick.

[@ROBRENZ]

Enjoyed Keith! ATB, Robin

[@joescarborough1]

I saw that look on your face early in the video suggesting, "I am not looking forward to this." Alas, it turned out easier than you expected. What a relief. All the best, -- Joe

[@chrismate2805]

This looks like good engineering, and your green lathe looks really good in your shop.

[@kevinbyrne4538]

14:30 -- The effects of the Evaporust are miraculous. I gotta get me some of that stuff.

[@ElmerJFudd-oi9kj]

Keith, you're the best teatcher ever. I have learned so much of you, thanks a lot for these video's, I love them! Take care. Chris.

[@MrLukealbanese]

I feel that you are founding a new Monarch-y Keith!!!

[@RRINTHESHOP]

Quite the complex taper attachment. Looks great after clean up.

[@josephmagedanz4070]

That entire lathe seems really well built, but the quality and detail of this taper attachment really shows the care they put into building the machine. Thanks for taking the time and effort to make it right and for taking us along on the journey.

[@sandrammer]

What with McMaster-Carr being up in Georgia you should get the bearing in a day. I get my orders down here in Jacksonville in two days on average from the time I order. Paint quickly!

[@ericpaul4575]

I get my orders the same day if I get them in early enough.

[@deweys]

what an interesting casting.

[@VincentParisien]

Thanks for your videos Keith!

[@isbcornbinder]

I use EVAPORUST. This is one product that always works better than promised. Try Evaporust in an ultrasonic cleaner.

[@talltimberswoodshop7552]

The bearing setup has some similarity to a Radial Arm Saw. In a RAS, the bearings are mounted on the yoke on eccentric bolts. The bearings travel in the ways machined into the arm. The stiffness of the travel is determined by the eccentric bolts pressing the bearings into the semi-circular ways.

[@carver3419]

Using pliers: "The wrong tool ..." A friend saw a sign in a Navy machine shop - "If the tool ain't right, the guy ain't bright".

[@JapanPop]

That Evaporust, though! Wow!

[@raincoast2396]

Looking forward to what you do to the oil galleries on the sliding casting. Looks intricate.

thumbs up, love the new no rust look.

[@2listening1]

Good afternoon, Keith and the Keiths! : ) (You have a lot of viewers named Keith, sir!)

[@Pnrc-b2u]

As always very instructive and enjoyable. Long may it continue

[@unclebobsbees4899]

Keith, I have a cast iron joiner bed that is fairly rusted. Evaporust or the electrolysis treatment you did on a table saw table? I can do either easily enough. Thank you, Bob

[@JB-gs8xf]

Keith I don't know if you noticed but the bearings have a very small shim spacer on each one. They are easy to lose if not carefull.

[@elsdp-4560]

THANK YOU...for sharing.

[@acidchristo]

Evaporust is best by far.

[@MadDawg91108]

Won't be long and that machine will be making money...and chips. It's been a fun journey.

[@neiltyson2408]

I crossed the bearings and this is what I ended up with: Vertical load taper attachment bearings (8ea), old number 77500, new number 6200 Horizontal load taper attachment bearings (8ea), old number 555000, new number 5200

[@MaturePatriot]

As Active Atom say, always replace the bearings. Did you mark everything so it went back into the same place? I got fussed at for using the "Hand Hammer"! At least it was well lubed. LOL 150psi should blow the gunk out of those those oil chases. That is one heavy duty taper attachment. Love your videos Keith, great work.

[@jacke.6634]

no scraping ?

[@davesalanzo6513]

How do i get it off the machine…

[@Smallathe]

V E R Y nice restoration Keith!!!

[@garrettmay6537]

Does any know where a person might find a taper attachment for a 17" south bend turnnado?

[@jacilynns6330]

why do i have a feeling that keith will be surface grinding a bow out of the taper attachment.

[@paulbarton397]

I did not get a good look at the part that clamps to the ways -- the one with the spanner nuts on each side. It should have a U-shaped channel underneath that corresponds to the raised section of the way. Often the end of the piece that is nearest the operator in use is broken off so the grip on the lathe is just L-shaped and just torques off when you try to cut a taper. This is probably how it gets busted. If I haven't made myself clear here and I probably have not, let me know and I'll send you a photo.

[@SciPunk215]

Sooo close !

[@richardcurtis556]

Everything engineered and manufactured with the same attention to detail as the rest of the machine. No making the taper attachment as an afterthought. That main casting is a doozy.

[@aserta]

Considering how gunky this was and how gunky these usually get (nobody cleans them, nobody) i think this one was lucky. Certainly dodged a bullet because once they get rusty and inoperable, someone usually wants to use them and they end up being abused.

[@franksalterego]

I will be thoroughly disappointed if you don't scrape and flake the parts of the taper attachment to match all the rest of the lathe.

You do no how to use something besides end wrench 😁😁😁😁😁
