Machinist's Minutes: Threading heads and the LANDIS Threading System

[@Hazmatt4700]

This is the kind of content that makes YT worth watching.

[@isaacandruthruss90]

Really really appreciate your videos. I had no choice except to be a diesel mechanic since I left school. I've been desperately trying to get my foot in the door as a machinest since I left school but no luck as nobody wants an apprentice. I've been in the trade 15 years now, and now I've started my own little businesses after hours grinding flywheels. I've saved everything I earned and now I own a beautiful old Finnish turret lathe and a tos fk25 milling machine as well as a couple of welders. Your videos give me hope that someday I might be able to leave mechanicing and be self employed doing what I've always wanted. Thank you for the hope you share, there is still room for being a manual Machinist.

[@Formerpoledancer]

I'm not a machinist but I appreciate that one day this level experience could be gone from all of the trades if it isn't documented.

[@jonadams6846]

Exactly,it has got to be passed on,CNC work is all well and good but for 1 offs or just one part thats needs machining,the good old fashioned small manual machine shops is vital to the working man who wants reasonable priced parts for his projects

[@DaveyBlue32]

Just a absolutely mind reading type comment about old of those guy’s who you just pray has had a couple younger guys who are just trying to absorb everything he drops into the universe!!! A local college or high school should have a couple real interested young guys who can spend a couple hours with him just watching a getting the education of an absolute lifetime!!!!

[@chuckthebull]

That is why I love his channel and a lot other manual machinists on KZbin

[@robertwest3093]

This is unfortunately true. With everything CNC these days the guys who understand manual machining are dwindling.

[@jeremiahthomas2669]

I'm not a machinist nor will I ever be but I love all the knowledge, and stories

[@allalphazerobeta8643]

When I go into a shop with your level of semi-organization. I think this is a shop that cares more about getting the work done to the best of their abilities than anything else.

[@CameronMcCreary]

I had a machine shop in the 1970s, 1980s and into the 1990s and I learned from the "Operation Paperclip" Germans and they taught me methods utilizing fast thread cutting starting at the finished end of the thread and cutting in the opposite direction and thread form grinding, which was very precise and highly polished.

[@TobeWilsonNetwork]

Interesting coworkers.

[@everettplummer9725]

We had triangles, as well as thread wires. We had done Acme and Square too.

[@jonschick]

All we had in the shop was geometric style threaders, several flavors. Sharpened them by hand. On small diameter, less than 1/2”, we had a tough time getting decent looking threads, even with new cutters. For one customer, they wanted Whitworth, 55* with a radius root and crown. Had to single point them and polish the crown. Grinding the cutter was tricky enough, had to go gently when making passes on the lathe with that radius on the cutting tool, the chip wanted to pile up.

[@higgs923]

Retied prototype machinist. Back in the Seventies I worked with Landis die heads on New Britain double-enders. Once you learned how to properly use - and sharpen them - they'd cut a lot of good threads. Much easier anytime than teaching someone how to single point.

[@derekgreen7319]

Great channel ! Alaska has to be a tough market for this industry. But it seems like you guys do okay

[@DaveyBlue32]

Your video are a lovely little escape into a little world of common sense and wonderful information about my new interest on a very small scale for the chainsaw cylinder engine building hobby !!!

[@jonwatte4293]

Your organization system is very similar to mine!

[@loosemouthcowboy4790]

The shop looks great. You can never have enough tools. Looks organized to me. It's an expensive endeavor with tools that you can hand down to your kids or your apprentice. Isn't it great? I'm an HD mechanic who uses these skills and tools. I learn something every day. Thanks for the information.

[@KikoValleyMan]

I’ve used the die heads on manual turret lathes such as Warner & Swasey and Herbert and also automatic screw machines. The toughest job was a 13 TPI high chromium stainless drain plug for tank engines. Ahhh the nutty smell of molybdenum disulfide filled the air.

[@donmathias1705]

I had a customer drop off 800 ss 316 tubes about 3 1/2 long. Needed a 1" pipe thread put on one end. Couldn't hold in rigid pipe threader. Would have been.a piece of cake if they had cut them.after thread put on. So set up lathe and used one die in toolpost and used travelling steady. Two swipes and thread cut. I did change cutting fluid to oil stuff. So one blage of a set of four. Ist cut got ris of a lot of material and second cut sized it.

[@shaunybonny688]

Sag mill lifter bolts, I don’t miss doing liner changes on those things 😬

[@jonadams6846]

Machined all types of threads,its a minefield unless you get the correct training in the very beginning,the strangest place I worked for threading was at Fisher Controls Rochester England,we had to roll threads and the drawing stated,length of thread to the last scratch +or- to •015,interesting

[@donniev8181]

Question, how do you insure the threading will start in the same place on each pass? Ive watched threading a bunch but that one question has always bugged me? Thanks

[@rustbeltmachine]

The machine and the operator ensures the threads start at the same place usually. @@donniev8181

[@chuckthebull]

Would love to see a video on what's the advantages and disadvantages of different types of threading methods

[@jeremyperala839]

Interesting. Thanks for taking the time to make these vidjas. You guys ever cook in the shop for lunch or does Howee make you pack musk ox sandwiches for lunch break?

[@davidlampe4153]

I’ve used geometric die heads in the past single point threads were done with CnC lathe’s or on manual machines but only for fixtures Manual W&S Production turret lathe’s were going out of fashion being replaced by CnC lathe’s Most of the shops that had Warner Swasey 3 or larger turret lathe’s were closed or a step away from being closed since they hadn’t updated their technology in 40 years.

[@rexmundi8154]

I added a geometric head and a box tool to a cnc lathe at work some years ago and people looked at me like I was crazy until the productivity went up

[@tilliesinabottle]

Thanks for the video. There is really not a lot of thorough information on die heads, just guys demonstrating their use. Even Warner& Swasey's Turret Lathe Operator's Manual is pretty brief on the subject. I don't know of any other books either. A comprehensive book or even a video out here on the various makes and models of die heads- like the difference between Geometric brand heads and those by Eastern Screw/H&G. Even just an explanation of the difference between Geometric DS, DSA, 00 and so on.

[@donniev8181]

Honest question, what determines the hardness of steel? What process is used to make a super hard steel as opposed to regular steel?

[@williambell7763]

Without getting too deep into the weeds of metallurgy, main decider is alloy (elements besides iron in the mixture). Elemental iron is relatively soft, you add carbon it becomes steel and is tougher, then other elements can increase or decrease characteristics you want. Some alloys can go through a hardening process and become significantly harder

[@williambell7763]

I guess a more succinct answer is the alloys can go through a heat treat (and temper) process that greatly increases the hardness

[@everettplummer9725]

Have you ever used a hardness tester? They come with a "Standard". You check your machine with it. A diamond, is pushed into the hardened steel, to calibrate. Minerals like diamonds, have a hardness of 10, sapphires 9. Glass is around Rockwell C of 65. Metal that hard, can be brittle enough to shatter. Drawing back after hardening, is often recommended. This rubber recycling company, had SS plates made, kinda like the slotted plates, on a meat grinder. We sent them out to heat treatment, ground them, and sent them out. But they shattered, heat treatment, didn't do any annealing.

[@everettplummer9725]

You would think, the new guy, would install them in numerical order, wouldn't you, and not use high rpm? Remember to tell them everything, twice.

[@robertwatkins364]

I hate 1018 steel. I just use 60 degree carbide diamonds to cut threads. I was showing the F.N.G one day how to get it done. He says ok, and he went to another lathe. He set up just like I showed him. After an hour or two I checked on him. He found a 55 degree diamond, and was cutting threads! Great! You just cut a pile of British Standard Whitworth threads! He thought I was joking . . . .I wasn't.

[@jonadams6846]

When i worked on capstans we always used floating heads for tapping now on youtube i never see them used,on mills or lathes its always fixed heads that worries me 😂😂

[@tonyjones9715]

Thanks

[@DaveyBlue32]

Hey there buddy!!!’ I’m gonna find a good old American Drill press and I’m just gonna drill a couple holes on the milling head and weld it on the shaft!!! I’m just trying to cut some aluminum off and base and squish band on the cylinder for a power increase! I can just grab a 2-D slide drill press base adjustment base.,, and I could even move the base plate if I’m not perfect square…. I am thinking about using a little pipe to go over the shaft and use a couple pins or bolt on…. Then I can use the hot-cold clamp and adjustment then tack it together so she can’t get knocked loose from the little milling action?? Also thought about just making several 2” thick metal blocks and a shaft to chunk and add some carbide to do my cutting?!!

[@jonadams6846]

Worst threading i done was on Cam autos and just brass brass and brass,i hated it whatever your wore,brass chips got EVERYWHERE, boots socks shirts 😢😢😢

[@everettplummer9725]

If you need more space, send me a Bridgeport and a South Bend.

[@maxzunker4100]

You know Howee! Some day in the future, when your peacefully resting in your grave, someone, probably one of your descendants will go through you old workshop and throw all that stuff that is so filled with technical history, into a skip bin that is headed for a landfill site! I know this because I work at one of these landfill sites and almost every day I see amazing old toolsequipment and machinery just going to scrap or landfill! So what was once a valuable and treasured tool or piece of equipment like you have casually laying around your workshop that old guys like me go all Ga Ga about, will be just an old piece of junk! Sorry 😢

[@HOWEES]

Have had several treasures turn to trash already in my lifetime. I have seen several grand-kids cleaning grandparents house' for sale & throw away even cash, and gold because they did not look close. : kzbin.infoKugpMaaGQ9w
