This week we'll share some viewer mail, a really good flea market score, then jump right into some machine work on the Monarch lathe, showing some 4 jaw indicating, and drilling.
Hope you enjoy! Thanks everyone!
Adam
Hi Adam, thanks as always for the video. You never have to apologise for late content etc. You put this out for free and I'm just grateful to be able to watch it.
+caahacky Your right man. We enjoy them when they come. And we will be there for as long as you need an audience. This the best reality TV.
+Martin Goudreau Thanks Martin!
That was Awesome to see and hear that big 2 1/2 in. drill bit !!!
Adam that tool box was a great find. Using a lathe dog to hold a drill is a great idea. I like that view with the camera behind the lathe.
Outstanding video Adam! Thanks for posting this. You are in my thoughts and prayers son.
I love the box. My grandfather had one like that. I never knew what it was, but I remember after his passing we went through his things and that box looked just like that one
Two of the guys I worked with bought boxes like your score at the same time maybe 50+ years ago. One of the fellows kept his covered with a heavy vinyl-wool cover. It looks like the inside of your box, inside and out. The other guys box was almost black from the shop air. I bought all the tools and boxes of the guy with the covered box so I would have a work of craftsmanship of my own. Congrats with the find... Thanks for the videos.
That tool box is a thing of beauty for sure! Great find. I'd keep that little dahlin' in the house. LOL
Beside the obvious machining and mechanical skills your really well spoken Adam, that's a pretty rare gift in itself. If you ever find yourself in western Canada in need of a beer let me know, I'll set you up🙂
I just love that middle drawer sized perfectly for the book every workshop should have.
Now you've got an excuse to buy a new box too.
+Adam Harrington ever heard of irrelevance?
Oliver Smith Seriously? You looked through my page to find other things I've commented on? Piss off .
hi adam,
worked in a shop for years, never saw a dog used that way.
even us old guys never stop learning.
thanks for all you show us, keep up the good work.
jeff
Thanks for the tip on the lathe dog on the drill bit. Nice score on the Tool Box.
Look line you need to take a few thou off the end of the tale stock so the bits will seat, or rebuild the sleeve. Just a thought.
The alternative would be to relieve the shoulder at the base of the drill bit so that the taper can go deeper into the tailstock. It wouldn't take much on those few bits where the shoulder hits before the taper seats firmly. Morse tapers have specifications, but you find quite a bit of variation on things like maximum diameter, minimum diameter, and length. As long as the taper angle is correct and the taper seats before the shoulder hits (in the factory/shop test taper) it is considered good. A slightly large taper in the user's machine can let the shoulder hit first, so turning the shoulder back is sometimes needed. No need to continue the taper angle - a simple cylinder is OK as long as it is less than the largest diameter on the drill bit taper.
Look at those chips Adam...! Great chips.... Very cool... Also, I never thought about the dog on the drill. Excellent. Thanks and cheers, Daniel
I have grown up in Toledo, oh. What a small world to here your home town on Aboms channel.
That is a gorgeous tool box. Awesome find!
Woo Hoo nothing like a bit grunt in a lathe, lovely chips :)
Thanks for the video as always Adam, love that tool box that thing is awesome, making me want one! Also that drill bit.. oh my
Adam, that Gerstner is pristine! I agree that it's probably not been used in a machine shop. You won't find another like that in the next 20 years. Awesome score.
+Richard Freeze Thanks Richard, I couldn't believe it when I found it. To think all the other regulars passed it by. LOL
Adam, thanks for the video and congratulations on that toolbox score. The dog on the bit is an awesome trick. Thanks for sharing. I have a similar issue on my tailstock (worn out I believe). I might take it apart and drill and tap an area for a setscrew like your monarch. Awesome video again. Thanks!
Wow, the cutting action on that bid drill producing those huge spirals were amazing even if the faces were not exactly equal! The tool box is in amazing condition internally but has clearly been stood somewhere pretty grubby for a long time!
We used to shim Model A axles with a a conical shim to get the wheel to fit. Since you are using a dog there wouldn't be much twisting on it, but it would be centered and tight. Just another view.
Love your stuff....
I use the dog on the drill against the compound whenever the drill is larger than the taper or if I expect the drilling to be tough. It works well, and protects the drill and tailstock tapers. I also use that idea on Silver and Deming drills. What I have heard about, but never tried, is driving the tailstock with the carriage to power feed the drill. As I understand it, you make a connector bar (or whatever) that will hold the tailstock and carriage together, and gently snug but not tighten the tailstock to the ways, then engage the lead screw. Ever tried it?
Great mail calls man ,And that was some bit boring on the lathe , Loved it !! Thanks Adam .. Thumbs up !!
Hi mate.What an excellent find on that Gerstner box, this must be one of the cleanest around. That box is nice enough to put in the house. What a shame that you are unable to use that drill bit yourself. By now you must have some shares in that company, the amount of tools that you have brought to work is astounding, I hope they realise that. It looks like you might have to give the tailstock a bit of a birthday very soon.Marcel.
+Marcel Timmers Alana's new jewelry box!
Yan Wo Sorry mate, but you might not have seen that they have split up. So the box would be for Stella's jewellery. Elena announced it on her site.
+Marcel Timmers Bummer! Sorry, Adam. Yeah, for your mom. Wonder how I missed the bad news.
+Marcel Timmers I don't mind using my own tools at work. They are good about getting us what we need, but when you have a full machine shop at home sometimes it's just easier to grab what you have, and use it. They all know of my tools though and the bosses have an inventory list of all of my personal tools.
Hey Adam, I don't know if anyone has mentioned this yet but regarding the tailstock, check under the quill for an opposite set screw thread as I think I saw a flat there too and it makes sense that there would be two or you're bending the tang and it won't actually tighten well.
giant drill bits are badazz, great footage of that.......
Great video Adam. I love that Gerstner tool chest. Nice score! Douglas
That Gerstner chest is awesome. Nice score Adam.
That tool box is a nice score!!
hey Adam! i have watched your following video to this one, can only remember that you mashined this setscrew for the tailstock.
i ran into the same problem, my livecenters doesn't lock on that worn out or reamed morse3 taper in the tailstock. solution was to face the the tailstock-bar about a few millimeters, so that the livecenters could go deeper in that taper. worked well! keep up your nice work an videos, thanks. greetings from germany
Save those beautiful big drill chips for Christmas ornaments! :)
+Yan Wo Or packing for Tom Lipton. :P
Wow, the stuff you are draggin out of that flea market is getting pretty amazing. There probably was lots of industry around Pensacola to retire from. Most is LONG GONE from upatate NY, so machine shop stuff is scarce. Nice box...Dave
David, we still have some industry around, but we used to have much more, the places people worked there whole life and then retired from. I get lucky sometimes at the flea market. Gotta get the deals when you see em!
+Abom79 nice video, I'm a retired carpenter, and really admire those old wood toolboxes. I don't think they are really that hard to make or duplicate, but nobody wants to take the time. you can tell they are built by craftsmen. When I bought my first lathe, the seller gave me a similar box, (9 drawers) with a brass label on it that says "RAYMOND HALL". I don't know if that was a brand or a duplicate with the builders name made for it. If any one knows please let me know. Any how thanks for the video and the lathe dog tip. JB.
Thats very fascinating to watch. Love the vids man. Keep them coming.
Wow,what a fond on that tool chest Adam, score!
That's a badass toolbox!
Thanks for sharing, Adam. You just made me wanna go back and view the entire Roller Assembly series, problem is it's 1:30 AM now! ;) Have a great week man, I always enjoy watching the content you provide us with.
+aryesegal1988 Always a good watch!
Great video and nice work as always Adam!
Nice video, Adam. I met a couple of the guys from Gerstner at an event last year. Seem to be nice folk. Good tip with the dog on the drill bit to help it keep from spinning.Get out and enjoy some of that BBQ butt this evening.
nice tool box Adam I have the exact same one but mine has been used quite a bit more I bought it for $400 on eBay but it did come with a few tools also
Great Gerstener tool chest Adam. I hope you can find a home for it. As said below "no need to apologise for being late or even not posting at a set time" We take it as and when it comes and are very grateful for it. regards from the UK
Super nice box!
Great video
Adam, Thanks for another great video! Harvey
Hi, Adam, After watching your videos, I think I'm much better at indicating my 4-jaw. The last .005 is the hard part for me. Thanks for clarifying how you pre-measure for the part.
+Pops on 2 wheels The last few thousandths can usually be done by tightening alone. It's trying to back off the opposing jaw just the right amount that makes it seem as though you are chasing that last thousandth back and forth forever.
G Day Adam, Would machining the front of your tail stock to allow the drill to go deeper and have better contact with the taper be an option? Im not sure if it is a done thing but it came to mind while watching.
Those old oilers are nice. There is a company called Starbolt in the USA that sells glasses if you break one. I import them to Australia from there if I need one for my old engines. Thanks for the videos, I do enjoy them.
+Bundy Bears Shed I have been thinking about doing just that as a quick and easy fix.
Big Chips! Thanks, CJ
HEY , Adam HowRU ?? I really appreciate the effort you do to get these videos out there , but don't over exert the brain thinking about how late it will be . Thanks for great videos , take care .
Lukenhiemer is the Rolls Royce of all drip oilers, the gas engine guys would almost kill for them.
+john walker Interesting. Thanks John.
Thanks so much Sir....
Detailed explanation of mounting and setting up of the work piece has answered a lot of the questions that I had.
As regards the tailstock/quill/taper issue with the Monarch, would it be too difficult or uneconomical to make a new quill from suitable stock?
Thanks again,
John Greenwood
+Aristakas Making a new quill is possible, maybe it can be a future shop project.
Hi Adam, that oiler would be a nice build project for home shop or apprentice, any chance a drawing or blueprint could be made?
Thanks for the intro to the Gerstner, that is a beauty.
As all say your the master on a four jaw Chuck.
great videothanks
Save those beautiful chips from the big drill for Christmas tree ornaments! :)
+Yan Wo - I've wanted to take a collection of colorful chips and encase then in some kind of clear epoxy for paper weight gifts...
+DSCKy I'll buy one. I'd also like a box of blue chips to scatter under my lathe (if I ever finish refurbishing it) to make it look like I know what I'm doing (which I don't). :)
My lathe is kind of small so I don't get a lot of the blue chips either. :)
Really enjoy your vids man!
I'm going to have to come out there and go to the Flea Market. The Flea Markets here have nothing but junk.
I have always found it odd that the tailstock on my Monarch has no provision for tang drive of the MT tools. I don't have a knock out hole either. I have to do full retraction of the ram and then it self pushes the bits out. I don't really have any problems with bits spinning though even on sizes to 3in. On the big boys I take a board and crank into it to seat the bit and then I do my cutting. That box looked really nice shape. Maybe some seamstress kept her sewing supplies in there instead.
+bcbloc02 Brian, look inside your tailstock and see if its got the built in tang drive. I bet if you dont't have a screw like mine it's made into the quill. If the big drills don't spin this may be the case.
That box is super clean.
I am sure it doesn't as I never have to clock a bit to get it in. I just slam them home when I put them in and they usually drive fine. On the big bits I just crank them into a block of wood and they seem to always sit tight enough for drilling. sometimes I can't hardly get the tail to turn back hard enough to knock the bits back out when I really get them stuck in good.
+Abom79 The quill on your Monarch tailstock is pretty interesting. The slot might not be for ejecting with a drift, it might be for pulling tooling in and holding with a wedge. Really old machines, like my boring mill have no tang engagement either, they used MT bars with slots through the taper. A wedge driven through the quill pulled them in and drove them. Old, old school....Dave
David Richards
My G&L is MT6 and it has two holes, one for the pull in wedge and one to eject. The book says the pull in is only used for face mills and tooling that might pull out, things like drills it isn't necessary for because the feed forces the bit in tighter all the time. I am not sure if mine has tangs in it or not, I suspect not as G&L had their own design that used 2 big lugs on the nose of the spindle to drive high torque tooling with.
exactly right, my 2.5 G&L has the same set up: #4 MT, no tang locks, two slots and the crossways slots across the end of the spindle. Yours must be #6MT or bigger. I've never seen any tooling with a pull in slot, but I'm going to try to cut some in some arbors that I have for it.....Dave
great but on the Gerstner. gorgeous box, would love to get my hands on one, just need to get a few more tools to fill that many drawers, is there a good fix on having a worn out or reamed tail stock like that on the monarch. other than repetition, what are some good resources on sharpening drill bits?
The tailstock can be repaired in a few different way, easiest would be to face the end off. You can use a reamers to make sure there are no high spots in the tapered bore.
There's been quite a few videos released on drill bit sharpening, me including. Google search is your friend.
$800-$1000 box. NICE !!
Why not make a whole new ram/spindle?? I think the lathe is worth it.
Adam, how do you go about repairing a tailstock taper?
Hey Adam: Seeing you mentioned it in this video, have you ever had a piece fall out of a chuck while the machine was running? I'm always kind of paranoid about that happening!
+watcherjohnny Oh yea, been scared a few times. One was a huge piece of pipe. Lucky I was turning super slow.
You can do that, or use something like wood also. Yes having a slug in the center helps to keep the part uniform.
Hi Adam, Are you able to sharpen those larger drill bits by hand, can you hold them steady enough, or do you need a jig to hold them? Interesting video, Adam, thanks. Joe
+Joseph Magedanz Yes i grind them by hand. My bench grinder has 12"x2" grinding wheels.
I would sand the outside and put a thin coat clear polyurethane and if you have an office table at home that's where I would put it.
Thanks again for another good SNS. Great score on the Gerstner and the Lunkenheimer 1 1/2. With the drill not seating in the taper, can you relieve the area at the larger diameter to allow it to seat in father? ( a straight diameter at the large end to remove some of the main body length ). When you were setting the 8" diameter part in the four jaw, that would have a been use of standoffs in the T slots. That's what I do in the 32" four jaw chuck at work. Thanks again Jeff
+JRD77VET Yes I could machine the shank a bit to allow it to fit, but it may be tricky to hold. I have used standoffs before when we had our big Monarch. Id like to make a backing plate like Tom uses.
+Abom79 Here's an idea to hold the drill bit in one of your lathes if it has a center on the tang ( most MT drills do ). Either find a piece of tubing or pipe the drill body fits in. Drill and tap two holes 180 across from each other to hold the drill against the inner most part of the flutes. Weld a cap on the other end. Put the adapter in the four jaw and the live center in the tang end. Indicate and cut the relief. I wouldn't get too fancy with the adapter since it will probably be a one time use. Jeff
Is there anything to be done with the inside of the tailstock? is it repairable by you?
+jusb1066 I'd like to know the same things. I wonder if it could be brazed up around the outside and taper reamer run through it?
+jusb1066 I was thinking that maybe he could pull the tailstock apart and face it off which would reset the depth of the taper.
Bradley Weingartner I thought about that too but modifying the quill just didn't feel like the right thing to do. No offense intended, I can't see any reason why your idea wouldn't work.
+metalhead2508 The taper isn't off per se, it's too deep - likely due to wear or past reaming. By facing the quill you restore that depth. If the taper is also in rough shape a reaming will help restore it, but will make the depth problem worse not better.
+TheDisorderly1 It's a tossup for sure, could modify the tool(s) as well. If the taper is out of spec however you don't have many options without perhaps sleeving it.
good episode of sns adam keep up the good work
l just bought Monarch lathe similar yours but 30" between center
its not arrive yet and lm wondering about the size of Morse taper drill
What is the size that fits the tailstock spindle ?
Mine is a #4 Morse taper. If your machine is about the size of mine if expect it to be a #4.
Good Stuff. :)
nice vid....for future reference "Cache" is pronounced "Kash". But you probably know this by now. I'm not a machinist but really enjoy your videos!
+Shear Stress Cool...thanks! :)
26:06 holy shit!
adam great recover nice video
Enjoyed the SNS buddy. ;-)
On that 2 5/8" drill, couldn't you just chuck it up and turn the shoulder back? The but end of the drill is probably soft, carbide would cut it fine .Shouldn't take much . only problem would be holding it.
+tim trott I'm sure I could, may be tricky to hold it.
I think there must be a Adam algorithm that determines flea market prices that only applies when he shows up. I bet Adam paid 1940's retail price.
+Doug Hanchard I bet your not far off Doug!
Love the Video....
My question is this, That Lathe Dog you used, could that not have been used on the bigger bit? Sorry for the question, but I'm not a metal worker, but I do learn a lot watching your videos.
+bheagle65 Not with it loos in the hole it would just bang around unsupported. The dog is just to prevent twisting.
bcbloc02 Ahhh thanks.... now I get it.... I guess some kind of Sabo like they use in shotguns or cannons, around the end of the bit would also not work then to center the end inside the hole.
+bheagle65 OOps it spelled "Sabot"... sorry. sabot /ˈsæboʊ/ is a device used in a firearm or cannon to fire a projectile, such as a bullet, that is smaller than the bore diameter, or which must be held in a precise position.
I'll bet you could send that tail stock spindle off to a machinist and they could make you one better than new.
+Tyrod 01 Tough to find one you can trust. :)
Take the tailstock apart! Shave .050 off the end. Sure, the measurements might be a bit off, but you can seat better!
That was my idea as well. 👍
+Abom79 Nah, just face the end of the drill bit above the shank since they are usually not hard there. Done it many times to use drills in older drill presses. Use a sleeve and center to hold it in the 4 jaw.Mike(o\!/o)
Moholo 88 I think the issue is that many bits are slackly held, so facing off will work universally compared to doing it for each bit.
+Cody Smallwood If there are many bits, then yes. Sounds like this is an odd bit which might also not fit other machines. Although, from the looks of the quill someone may have buggered the tang slot, drilled and reamed the quill and added the setscrew to drive the drills. I would have to see it to be sure. Never saw a setscrew used like that and some machines don't drive the tang just use the taper.
Yeah, I have a smaller one at home, and the quill actually slides in. Indexes to a slot. The set screw causes another major problem: imbalanced force on one side throwing the bits of center. Unless you use two... But then it's too much work.
I remember Adam saying he believed it had been out thinks it was reamed, and that most of his bits are sloppy, not just these but ones.
Love the back and forth. These machining channels have very active members for sure!
GERSTNER and sons are still in business , still family owned ...
MAde In uSa
not cheap...lol
24:30 why do you do those 2 pre cuts? (the one in the center and the other).
Sorry i'm not an expert of manual lathes.
+Modelero Makes pushing that drill through easier, it relieves the center so that there isnt so much pressure on the chisel point of the drill, the machine, and the workpiece.
+Abom79 I mean the 2 pre cuts before facing the entire piece, i don't think they are related to the drilling.
if you do not know what to do with that toolbox, I habe an idea .....
TL had no chance to win the throwdown :)
+Steve Allen I think he was planning on the outcome. :P
What is the make of your lathe???
+Rolando Escobar Monarch I think.
It's a beast!! What is the swing and length?
Rolando Escobar Sorry but i don't know the length and swing but maybe someone else does ;-)
I'd like to know who the idiots are who vote down your videos.
+Yan Wo Just have a look at the dislikebar; Its about as big as their dicks...:))-
