You are correct about the use of smoking or what ever , when I was metal detecting years ago at a foot ball field, a teacher came up to me and asked me to hunt for trumpet mouth pieces , and if in could please return any that I might find ! after about hour of running that one through my brain, told teacher kids are pos lying to you, they are making pot pipes out of the bowl part, then telling you they lost it marching on grassy field ! He looked dazed ! but mad also !!!!!
Speaking of gaskets, my dad would occasionally make a gasket for a steel surface by placing a roughly sized piece of gasket material directly on the intended surface, and cutting it by tapping upon the material against the edges using a brass hammer. Oh and the fellow with the file has the blade 90 degrees wrong in the vise. It will flip out of there on no excuse at all. Not to mention, he's working it so far from the point where it's (badly) secured that it will certainly flex, making accurate filing next to impossible.
Didn't know the shock tool because I always went for the hot wrench and a coke bottle of water to put the bushings out. If you were good with a torch you could drop a set of fronts out of a 73 Nova in 5 minutes. The KD tool doesn't look like it was successful very often, especially here in the rust belt. Surprising, most KD stuff was (is) well made and effective. Looks like the price of cork borers will be going up on ebay, what a great gasket punch! Thanks for another fun whatzit!
I have a set of 4 aluminum cork borers and the center ramrod as the 5th piece but I use them as cheese borer/sampling tool for sampling cheese in varied sizes and especially large wheels of Swiss Appenzeller, Raclette, Italian Parmigiano-Reggiano. I thought they were based on pineapple corers or apple corers, I never would have guessed they were originally cork borers for lab use, or even cork-bark borer. Thanks for your information.
Thank You for documenting so many of your machining talents for the all of us to have access to forever. I am a 53 y.o. semi retired bus. unit manager for a corp. and aspire to work with my hands and learn the craft of machining over time and a retired hobby. love your videos.
I reload brass shot shells for my Remington Rolling Block in 20 gauge. That cork boring tool would work outstandingly for powder wads and over shot wads. Thank you . Now I need to find me a set.
You know, we had a cork borer just like that at school - and I always wondered what it was for so I was really curious on the "Answer" part of this one! We always used to hold the thing horizontally, extend each of the inserts as far out as possible (like a radio antenna) and then turn it vertical. All the inserts sliding down into the largest barrel and hitting each other made for a machine-gun-alike sound. Thats what we used it for, anyway :D Thanks for making this series - so many people throw valuable tools away because they just do not know what they are and what they're good for! Best Wishes Adrian
At a fuel depot lab in the Navy we had various "cork borer" sets, the one in this video actually was used in a vise and spindle type of contraption, the t handles fit into a kind of fork which had a crank handle, the cork (rubber) of different sizes fit into the tapered vice jaws (for lack of better term) and the handle was turned and the threads pushed the bore through the corks and out the end. It all came in an elaborate wooden box with pieces and parts stowed in various niches and trays. They even had an engraved nameplate with the federal stock number etc. Fond memories.
lol, love the way the pro-filer has that blade held in the vise. I guess an amateur would hold his cheap file against the spinning blade on a running lawnmower.
Never seen a cork borer like that similar to a set of leather punches I used to make holes in gaskets sometimes I made many gaskets using a 4oz ball peen hammer or brass hammer tap the ball end of the hammer over the holes to make them always had gasket material to make them I still use the fuse puller a handy tool in my trade of commercial refrigeration Love those special tools keep them coming
OMG! At 4:07 you show a page from the Welch catalog with a cork-borer sharpener. I have had one of those on my desk for several years. I had no idea what it was, I was just waiting to send it in to you so you could figure out what it was. Thanks!
When I took chemistry classes (in the 1970s), I don’t remember any real corks in the lab. Instead, we had rubber stoppers, gaskets, and O-rings. I think most were natural rubber, but some may have been silicone or some other synthetic rubber substitute.
The numbers on the cork borers are for the number of the glass tube they are to fit. The number is the number of 1/16" increments. So a number 5 would be for 5/16" glass tube.
Had one of the borer/gasket tools when I was growing up, was wonderful for making rings, you punch the inner then the outer. Several sealing "washers" for carburetors that I never had to buy. You could use it and the press knife all day and make a paltry living but not having to wait a week for a city trip to *order* a gasket rocked. Got pretty good at it.
THANK YOU THANK YOU THANK YOU!!! I have a cork borer set and sharpener. I never knew what they were for. Used them for gaskets like you demonstrated. Awesome video Mr Pete!
The brass tree, is a Hand Gasket Cutter , a cork bore has a flatten top as your catalog showed so it fit in to a small Press or could be tapped down easier with a lab mallet
For the last clip cutting gaskets ... to make Bell Punches ... I take old hole saws that are dull and grind them to a sharp edge so you can cut gaskets just like that.
loved seeing the cork borer, the technical (secondary) school i attended from 1980 to 84 had one, but the students rarely needed to use them. in 1983/84 i was also a part time lab tech, so i'd do all the prep work to save teachers and students time. it was great being a student and having the keys to 1/2 the school lol
That shock tool might have been useful out west where they don't have or use much salt on the roads...here in Ohio like many other eastern states, they throw tons of salt on the roads that eat away at those flats on the tops of shocks and so even vice grips will often fail to grip them or the flats are so weakened from the salt that they just twist off leaving you nothing to try and grip on again. When I have the room I use a die grinder to slice the nut part way and then take a chisel to split the nut. Worse comes to worse, get out the liquid wrench and burn it off but gotta be done outside and have a 2liter pop bottle pull of water to put out the rubber that catches on fire and quickly puts off noxious smoke!
The rubber stoppers can be bought with holes molded in. The cork borer can be made to work in rubber, but it won't work well, and is most likely to bore a hole in your hand. The cork borer is really intended to be used in actual cork.
Rubber stoppers were preferred until one had to generate or store chlorine gas. In a few hours the rubber would be destroyed by the chlorine. Cork stoppers had to be used for chlorine.
The DePuy tool is a surgical instrument that I am pretty sure is used in hip replacements. I am a retired surgeon and it looks familiar. Often when they were putting my instruments in the autoclave, they were pulling some other surgeons instruments out.
The cork borers work terribly in rubber, but you can freeze rubber with liquid nitrogen and use a regular drill. However I was stunned to learn that this other tool, we have lying around in the lab is actually used for sharpening these borers. I always thought is is some tool to widen tubes for glass blowing.
I am a Scientific Glassblower. The cork hole drills are only for cork. The rubber are made that way. You should hold the cork against a plastic or wood surface and turn the drill to cut. Do not just push.
@@mrpete222 🎉🎉🎉 A cork borer, makes sense now. Thanks for identifying it Mr Pete 👍 I got one with my dad's stuff when he died the other year. Drove me nuts trying to figure out it's use. Dad ran a brass and woodwind instrument repair shop for years, I thort it might be measuring device for brass tube sizes but now I believe it would have been used to cut felt or cork seating pads/washers for flutes and saxophones etc. Mystery solved ☺️ Cheers from Tasmania 🍺
I used to work in a chemistry lab so recognised the cork borers, although we had the type illustrated in that book. I'm not sure I ever used them though (nearly 40 years ago now).
I hope that add is a spoof , he's doing everything wrong. So the use of a Nicholson file obviously doesn't make him a professional. Blade is held too high, clamped in vise on edge and 90* to the way that would be the most appropriate.
I remember a couple occasions in chem lab when a less dexterous student would try to bore a cork while cupping it in his hand. The borer would come through the cork and into the palm of his hand. Not a pretty picture, but maybe it was some form of natural selection to get those klutzes out of the lab before they created a major disaster.
THANK YOU!!!!! I have a cork borer exactly like the one you showed in the catalog. I inherited it from my Dad who was a scientist. Later, he had Alzheimer's and could not tell me what it was. And now I know!
That's an...interesting way to sharpen a stone flinger blade. Also no safety squints, just stare down that blade like your about to murder it in a Kubrick film. That'll do it.
3:05 If that's a lawnmower blade he is sharpening in the ad, I would say the blade doesn't look it is clamped in the vice on it's flats but on its edges, and he is filing it from the wrong direction.... I was taught to start the file from the direction of the leading/sharpened edge to help prevent roll-over of the sharpened edged
I retire this week. I used the cork borers almost daily for cork and tubing. Real cork needs to be supported by a rubber backing. We hid ours at university as well making gaskets has never been difficult with a cutting mat backer.
I recently had to cut some holes in some rubber stoppers, that device would have been handy. I ending up using an arbor press, the freezer, and a hollow punch.
No doubt about the students... I had a small cottage industry of making bongs out of lab glassware that my brother would pinch from his high school... Now I regret cutting holes in all of that very high quality glass :- /
Finally figured out what Tubalcain meant. Last night in bible study we were in Genisis chapter 4:22. And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah. Very nice.
i was touring portugal on a motorcycle a couple of years ago and i could not for life of me work out why they were cutting the bark of the trees, it wasn't till i got spain when saw a truck load of it by some traffic lights that the penny dropped
I was sold one of those from the snap on truck and was told it was a spark plug wire puller. I told my wife it was for going to the toilet when you have greasy hands
Warning!!! You NEVER pull fuse while electric circuit is LIVE / HOT.. even with designed fuse pullers.. if you have no choice and have to pull fuse HOT make sure you wear proper PPE that is rated for that... to many folks lost their life due the shortcuts or lack of knowledge... Please be safe!!!!
The file add, that now you place a lawn mower blade in a vise, nor do you file furthest away from anchor point as you can get, and also looks like he's filing back edge of blade not cutting edge
guy filing the mower blade, you got to mount it in the vice close to the jaws otherwise its just gonna bounce off the file. also, i hope sarah keeps sending weird tools and personalized letters.
I've seen many mechanics use the fuse puller as a spark boot puller. they will rip the boot if not careful. Allen Diagnostic Machines came with a boot puller just like the black one in the video. They will rip the boot also if not careful.
I was going to loan you my cork borer sharpener (just like the one pictured in the catalog) for a future Mystery Tool episode, but that now won't be useful. They are available from Amazon in various designs, qualities, and prices.
