Meatloaf 137

[@jezelkins]

RIP Jim! I worked on a few projects with Jim over the past 33 years. We shared many interests. I loved seeing Jim's yearly photos of the special tree in Death Valley, that he would photograph each winter. I miss him a lot. He actually talked about you, and how you helped him with his many microscope parts. I remember he built a couple of them for young scientists, at "work." It has been a couple months since I heard of him passing. I am very sad. I learned the ins and outs of Ebay from Jim. He had the most precise electronic instruments in the lab. They were his own; and he would use them to calibrate users equipment. I truly enjoy your channel.

[@danielyoder3358]

Tom, I took two years of Tool & Die Technology from David Murkens, he was a great teacher. I did make two of his Indictor Bases. They were experimental, slightly longer and slighty wider then standard, to see if they were more stable. They turned out not enough more stable to make the added material cost worth it. We are talking in the millionth's scale. Meadville's tool & die businesses are still going strong, throw a rock snd you are liable to hit a toolmaker. Channellock is still here and still owned by the family. The zipper was developed here by Talon, McCroskey tool was on South Main Street. Talon trained a lot of the first tool shop owners here. Have a good day. Dan

My dad was a pathologist. He used those blades in a microtome that relied on freon to freeze a sample prior to slicing for making slides. Those machines had an open top because the cold freon would stay down in the chamber where the blade and sample were. Many a pathologist was killed because they would be so focused on the work that their nose would come too close to the freon and, without realizing it, they would breath enough freon to pass out. Unless anyone knew what was going on and quickly got oxygen back into their systems, they wouldn't make it. Sorry for the dark post, but it triggered memories of that machine & my dad.

[@matzbol4812]

This microtome blade brought up memories. I used such knives for many years. We handled them like precious jewels. After each use they were taken out of the machine, cleaned, oiled and put back into the case. Once I was spreading oil onto the knive with my fingers when a guy dropped in and asked me something. I turned my head to answer him and when I turned back, my pants and shoes were red from blood. What happened was, I turned the knife to wipe oil on the back. But I had turned it in the wrong direction. That damn thind was so sharp that I did not feel it slicing up my thump. My boss asked me, if I had cut into the bone. He was worried I might have damaged the blade... P. S., Wilhelmshaven is a town at the coast in Northern Germany.

I guess your boss had other issues too... I'm glad you survived ;-)

LOVE THE TRAILOR HITCH MOD

[@EverettsWorkshop]

Man, you get to play with some cool stuff. That is some awesome gift from Jim to you in the microscope kit, as well as the new microscopy tools that were given posthumously. As for the "trailer hitch," I like that idea and will be incorporating it into my hobby size lathe - Gary Brown linked his with a tie rod but yours is simpler.

[@user990077]

My cat's ears perked up when you mentioned tuna can openers at the start of this video.

[@LaneyMachineTech]

So good to see Jim’s stuff! He often talked about how sharp those microtome blades were and he was constantly worried about slicing his fingers off 😆 Jim was a kind and fascinating person. I learned tons from him about all kinds of optical devices - not just microscopes, but telescopes and cameras too.

[@fna-wrightengineering]

Hey Tom, awesome meatloaf as always. That "trailer hitch" is really clever. Being able to keep track of the tailstock position can be a very useful thing. Combined with a scale on the quill, it makes drilling to a precision depth super easy. It's especially useful when drilling high-aspect-ratio holes, where it's faster to pull the whole tailstock back to clear chips, rather than cranking the quill out and back in. I figured that since DRO scales are simply encoder strips, and that read head is where the magic happens, I could add an additional read head to my existing Z-axis scale. This way I didn't have to add another Z-axis scale to accomplish what I wanted. My DRO has a"W" axis, which can sum itself with any one of the other 3 axes, and this is where I connected the additional read head. It adds to the Y axis scale, which is on the tailstock quill. This way, I can move the quill, or the whole tailstock, and not lose position. (I've actually got a video series on this on my channel) Combine this with something like that Morse-taper quick-change unit you showed earlier in this vid, and you could build a precise, repeatable, quick-change tool library for tailstock tooling, to complement your QCTP library!

[@fristlsat4663]

An optical cleaver doesn't actually cut the fiber, it makes a very small nick in the fiber, which is then flexed in a very controlled manner away from the nick, and the fiber breaks. A properly calibrated fiber cleaver will create a very flat, very perpendicular end face, appropriate for fusion splicing or other termination methods, or sometimes for situations where a naked fiber end is required. When I was playing fiber jockey back in the early 90s our Fujikura cleavers were tested to produce a flat end cleave with

Tom, I enjoyed it all the way as usual. Thank you for doing this. I'm quite able, as a machinist and a designer, but I still learn, and enjoy, from you. There's so much out there; live is just too short to know, understand and use it all. Internet has it's known downsides but your channel is an example of how it should work. Teaching a wonderful trade for the rest of the world. Everyone with an internet connection can learn the trade, rich or poor, close by or abroad, in their own pace. One small tip from my side if math isn't your strong side; the compound angle is: arctan (D-d)/L where D is the big diameter and d is the small one and L is the length of the cone along it's axis. Furthermore, no nagging, I wouldn't have picked brass for the extensions in connection with the zinc aluminium alloy used in moist conditions. But on the other hand I guess the car only comes out in the sun the following 300 years... Studebaker, Raymond Loewy; check him out! If you're a Lucky Strike smoker; he designed the iconic logo. And a superb high speed steam locomotive and, and. If you don't know him; go check him out. He's a legend for designers. Thank you Tom, best regards, Job

I'm thinking that my dovetail bed on the HLV-H won't work as well as the setup you have as gravity is (presumably) pulling your tailstock down onto the vertical v-way.

Regarding the artillery clinometer: Not a Swiss company, but indeed a German one. Kuhlmann KG started in 1873 as a clockmaker's shop and soon began to focus on producing instrumentation for naval plotting, navigation and targeting. They are still in business today, making cnc mills, grinders and tooling. There IS a city called Friedrichshafen on the shores of Bodensee lake, quite close to the Swiss border. Maybe that tripped you up. Does that to me all the time and I'm German ;) Thanks for the meatloaf and your awesome and inspiring dedication to knowledge and your craft!!

All can openers were originally meant to cut on that axis. Most still can be used that way, though some cans aren't up to spec for a normal can opener anymore.

"Here we have a diamond knife blade, sharpened to a few nanometers." -- runs finger along the blade --- "Yes it feels sharp." Under the microscope, we see that the edge has some defects, with cleavage features only a few atoms wide. So a super sharp blade, with serrations that are even sharper. It was fun to see the interference bands on the bevel of the edge.

[@royreynolds108]

Tom, if you make a short bar(2 to 3 inches + or-) with a spread opening on each end that will just fit over the bar on the carriage and the tailstock on the other end and then drill the holes through the prongs to match the holes in the carriage and tailstock, you will be able to take out most of the wiggle of the pin you are using for the coupling. I have made similar bars to couple rail cars together, only much much larger and heavier. The ends of the coupling bar do not need to be at the same height but should be parallel to be effective.

Hi Tom, the W.M.35 on the clinometer case and the clinometer stands for "Winkelmesser 35" ...winkelmesser is a german word for clinometer but literally translates to "angle measurer" ;-) the one you showcased was made in Wilhelmshaven which is a city in northern germany on the coast not far from Hamburg

[@Mishn0]

I thought "messer" meant "knife". Would it be "angle knife"?

[@youtubeonly7541]

​@@Mishn0 Messe(r/n) is one of those false friends that sound very similar but have different and unrelated meaning. Messer = knife comes from s(e)ax, which today refers to a specific anglo-saxon knife type. Messen (to measure, lower case) comes from Maß or measurement, a device that measures something is a Messer, usually prefixed by the unit. Messe can mean church service from latin? missa, but also trade fair. Messe is also a nautical term for dining room, you may know it as mess hall. Once you add plural to this mess it becomes impossible to tell without context, even for a native speaker.

[@HolzMichel]

@@Mishn0 a "messer" can be a knife in german too. although in this case it doesn't mean that. there are many words in the german vernacular that have dual meaning.

[@MrShobar]

Arctan (.030)=1.713 degrees. The end of the optical fiber must be lapped after it is severed. Otherwise, an impedance bump will occur due to optical reflections from the splice.

[@fristlsat4663]

For the purposes of fusion splicing or gel matched field terminations cleaving is the last operation before termination, in fact the fiber is cleaned the final time before it is cleaved, and never touched again. For terminations that are lapped (either dry or wet (epoxied) terminations) the fiber is lapped to matched the end of the ferrule in the termination, and actually, for those terminations the cleave is not as critical as it is for fusion splicing, since the lapping both sets the end of the fiber flat with the end of the connector, and will polish out any submicron irregularities. Generally fusion splicing will yield extremely low forward loss, and very low backscatter numbers, at least with properly matches fibers. Things get a little less reliable when splicing unknown fibers, and becomes a real art when doing stuff like splicing a single mode fiber to shoot into a multimode fiber. Obviously you can't go the other way, that could very well have more backscatter than forward transmission.

Interesting set of tools. Thanks Tom. W.r.t the inclinometer, Franz Kuhlmann is a famous German mechanical engineer and entrepreneur from the early 20th century. He developed a company that was famous around Europe for its drawing instruments/machines and its drawing tables. I guess that the company still exists and is in the CNC business. Nothing to do with France or Switzerland.

[@jobkneppers]

I owned a Kuhlman parallel drawing board. It was a joy to use as long you kept the guiding wheels clean. The grease on the bars collected dirt which caused a bumpy ride moving your scales along the table. Isis made a superior 4 bar solution with only rotating bearings; no cleaning, no maintenance. I liked to buy one back in the day with no real money at hand but then I learned to use Autocad and all these lovely mechanical pieces went obsolete. I enjoyed drawing with pencil and ink. Correcting and changing drawings with a razor blade was a pain in the ass. If you didn't scrub the corrected surface with a hard "Rotring"or "Shaefer" eraser long enough the ink would bleed into the surface of your drawing. And then things got difficult....After learning this I went to a shop "lichtdrukker" in Dutch (no idea what the right translation in English is for now) where they could make a polyester "acute" copy which was really durable and you could scrape it several times without ruining your drawing. Those where the days where I learned to plan my drawing with minimal views for a complete overview of the part or parts to be defined. This knowledge still helps me using CAD. Like Bauhaus learned; less is more :-) Best, Job

I would think the clinometer was used to set the angle of the cannon barrel. Using a map from two known points gives you the distance from cannon to target. Your firing tables tells you with this shell, with this much powder, you need the barrel at this precise angle to make the hit. Mil radian was simply a precise angle change in this case. The key to adjust the bubble may be just for calibration, or for your known height above sea level, not sure.

[@vitesseguy]

A little research on Meadville PA revealed that it was the home of the Talon company who patented and produced the zipper. Making the zipper required an assortment of high precision machine tool companies to produce the tooling etc. The zipper had enormous demand.. By 1900 Meadeville was called "tool city" and claimed the highest number of tools/machines per capita in the US.

[@russkepler]

I believe you reversed the use of the mil scale in a scope - it's more often used to estimate distance from a known height. Since you're generally targeting opponents you can consider them a bit less than 2m tall, so 2 mils at 1km, 4 mils at 500m, etc. Makes it easy to estimate distance by directly comparing them to the mil dots in the scope.

[@dizzolve]

53:00 I splice fiber. Nowadays the cleaver blades are circular so you can rotate them every so many cleaves. ...... They're about 3/4 inch diameter but the thickness is about 1/8"......... talk about sharp..... you must be careful when changing these puppies. To answer your question tho Tom, yes once cleaved the fiber is ready for fusion .... or even mechanical splice

meadville is, or was anyway, an interesting place. when i was a kid, erie was heavy industry, foundrys and heavy stuff like that. some of the plants made real big crankshafts for ships, boilers the size of a small 2 story house etc. it had a port that received tankers of iron ore, etc. the schools were geared up for it too, 7th grade shop you had to make a cored pattern, and by the end of the year you had learned enough sand crabbin technique to name all the procedures and tools, mix sand, and at least bust molds on the shop floor. meadville was the first (and only) bigger town on the rail line south to pittsburgh, (it was like 6 tracks wide like when it went thru meadville) and had a fair share of industry as well. channel lock (pliers) had a huge plant there, it still has a bunch of buildings infact but i always get the impression there are more corporate offices there now. it always breaks my heart when i go thru there these days and see those big presses, punches and the like sitting out in the weather next to the tracks and long (n old) empty brick buildings. anyway it is about 1/3 the way heading south from erie to pittsburgh, and of course you enter a different watershed on the way. the old major highway (i think it was rt219, i just call it edinburro rd) that went out of erie, went thru meadville as well. now they have an interstate going from erie south and thru pittsburgh and it grazes meadvilles west side. pittsburgh and erie were the core of industry in pa when i was a kid, and betwix the 2 are still,.... but in the past there was alot more pattern shops and tool n die shops all thru there. a lot of that dried up since i left the area (late 60's) but i noticed something sometime say in the late 70's. i knew a guy who was a "job shop" pattern maker for mostly bethleham and other foundry's in buffalo, he lived in what they call the southern tier and did it all from his shop on his property. which is in the hills south of buffalo before you hit the pa line. he told me yeah all the shops that can make small stuff remotely are all thru here since all the mills have been having hard times. you don't have to be in buffalo anymore. i started noticing that after he said that and yup, tool n die shops, and mold shops are typically on the fringe or in the boonies around here now adays. i sometimes think the fax machine had a little to do with that. but they cluster around the periphery of where the old industry was...like meadville. between there and erie are scads of small high quality shops imho anyway. injection mold shops are what you see a lot of these days in the off the wall places. if i remember right tupperware had their 1st shop down towards endinburro (north of meadville, south of erie) my brother was friends of the owners 2 sons and they had the 1st snow mobile we had ever seen. it was a gas to drive, and it was the only one i ever saw till 20 years later i bet. and now that you got me rantin, just east of meadville on rt 6 which was a major east/west road before the interstates) was where the oil industry started. so all the blacksmiths who were busy there ended up getting into other iron manufacturing as that industry got creaky. meadville probably had a good labor pool at the turn of the century. if you ever get the chance to enter meadville on the main road where the state highway barns are they have taken all manner of signs and cut them up and made flowers, buildings, anything you could imagine as art and hung them collage style all along the fence line, plus a signage flower garden in the grass space infront of the office parking lot. it is beautuful and a true tin knockers dream. i'll climb off the soapbox now. :0}

I think the unit employed is the angular mil rather than a milliradian. A milliradian is 1/1000 of a radian, or 1/(1000 x 2pi) of a full circle, so about 1/6283 as opposed to 1/6400.

Us without machines or out in the boonies would simply fill those grill pieces with JB Weld, drill, and tap. Or if in a hurry, put a couple strands of copper wire in the hole and put the screw back in. Then maybe 29 years later when the lens needed replaced the next guy could bring it to you for the ultimate fix.

Hello Tom, it appears that the artillery protractor was made of nickel silver (in german: Neusilber) material. Other names for nickel silver are Alpaca/Alpacca, Argentan, Minargent (source: german Wikipedia).

I've never saw a tool like that to cut fiber before but all freshly cut fibers must be polished/lapped after cutting.

The modern fiber optic splicing tools use a Cleaver to cut the Glass Fiber , then can be heat spliced back together or use the 3M splicing connectors . The days of lapping Fiber Optic are long gone since late 90's early 2000 since 3M and others have developed the easy connectors and splicing kits

Isn't the can opener bladeless? it doesn't cut into the can, it just bends out the lip and the connection on the lid can be undone with the pliers (on the side of the opener)
