Shoot'n The Poop #3 - Variety Show

A little mash-up this time around: I share my thoughts on tungsten electrodes for TIG welding at home (we even get to measuring the radioactivity of Thoriated tungsten!), my thoughts on Insert Tooling in the home shop, and my first try at dressing a resin bonded diamond wheel (mixed results).

I'm currently a nuclear engineering student and I think that it is pretty cool that there are electrodes that use Thorium. Honestly the dosage you're gonna get isn't bad. If you're a weekend welder, I'd estimate that your average dose from doing a project with thoriated electrodes won't even approach half an mrem. You get more radiation dose than that from something silly like trace radioisotopes in your spouse's body if you sleep together every night (well, maybe not, depends on how recently you got married). Average yearly dose for someone in the U.S. is around 360 mrem, for context. The main issue, of course, is the possibility of inhaling thorium or thorium oxides. Simple ventilation and a breathing mask should be pretty sufficient, and you want to be especially careful when you're grinding the electrodes that you've got some ventilation going. Overall it's just a little bit of Thorium, nothing to get your pants in a bunch over. If it was super dangerous California would probably make it illegal or something. Heck, secondhand smoking is MUCH worse than thoriated electrodes could ever be for your health.

[@OtterFlash]

I caught this video while I was washing dishes and heard the radioactive talk out of the corner of my ear so I dropped the dishes and rewound to hear it again. I can only tell you that working at a nuclear power plant for 31 years as a Radiation Protection Tech we never concerned ourselves with the tungsten welding tips in regards to occupational radiation exposure and believe me we track many many things in that regard. The tungsten tips were only a concern for us in that they would cause our monitoring devices to alarm when workers forgot they had them in their pockets and tried to exit the site. We would have to head over and confiscate the tungsten and make sure the worker cleared the monitors after that. Love the videos and can't wait to check out some more.

I was watching just waiting for him to point the geiger counter at an open primary power line or the fluorescent lights in his shop and get a reading higher than the tungsten lol. Seeing a home inspection done on a house near the really big power lines with the metal towers holding them up and seeing the inspector get higher radiation readings from the old light tubes in the basement than he got standing right under the power lines was mind blowing

[@garybaris139]

I know this video is pretty old already but several years ago I worked in a manufacturing plant that made crankshafts for earth moving equipment and we had a lot of CNC machines and lathes. The lathes sometimes plunged straight into a 5mm cut (not sure what that is in inches) which used to scare the crap out of me. Some of the other insert based machines took even heavier cuts than that. I still regret not taking videos of the machining. The swarf in the lathes used to hit the window in the safety door like a handful of gravel being thrown against the glass. The lathes used to have about a half inch stream of coolant on the inserts but the other machines cut dry. Only once I experienced this, did I realize that we were only toying with the inserts in all the other machine shops I've worked in. The thing that surprised me even more was how long the inserts lasted taking such aggressive cuts through the hard outer layers of the forgings.

[@bytheseaaspirinshop801]

Lanthanum and thorium are both weakly radioactive, lanthanum being just slightly more so. Neither is is probably as dangerous as a chest x-ray. Just don't ingest or breath the dust and you'll be OK. Pencil lead is worse than either.

Granted .09% of that La in the electrode is superficially radioactive, background radiation is likely 3 or 4 times higher than the electrode unless they use a 138 enriched lanthanum in the electrode.

[@AdamEarl2]

Love the video! I'm a manufacturing engineer at an automotive company- you're talking my language here. For dressing CBN wheels we use a diamond - usually a rotary blade (it's a 4" wheel mounted on a high speed motor). The blades are around $3000 USD. You can use a single point or cluster diamond. I think you may be loading up the wheel with aluminum oxide from the grinding wheel which will not help with making a clean cut. A loaded wheel generates a lot of heat and you can burn the carbide when resharpening (this causes microfractures on the carbide surface which lead to premature failure). You are spot on with the carbide inserts- need the right machine. 500-800SFM is needed, there's even more exotic inserts (cermets, silicia nitride, CBN) for cutting faster (+1200SFM) or hard material around 60HRc. High pressure coolant around 600-1000psi helps to break the chip. For your finishing: a smaller nose radius (0.4mm), D or V style insert, and positive rake (not double sided

[@ThisOldTony]

+Adam Kraehling You know I should've tried with the single point diamond. Thanks for tuning in Adam.

[@sweetpeaz61]

Hi Tony, another great video, thanks! About inserts, I was taught a rule of thumb when I was an apprentice, feed rate for good general finish is 1/2 insert tip radius...it works out pretty good as a starting point. Also from experience, on manual lathes if you got stringy rats nests going on with insert tooling a combination of coolant and reducing rpm will help. the heat in the chip makes it maleable so it flows rather than chip breaks.

[@agate_jcg]

Physics note: the main decay product of thorium is an alpha particle, which can't penetrate through the housing of your geiger counter, but can still give you a lovely lung cancer if you breathe some thoriated electrode dust. I don't have the expertise to say whether thoriated electrodes are actually harmful, but I can tell you your geiger counter isn't measuring the dangerous stuff.

[@l.p.5259]

Jason Goodman I think all the cigs boilermakers smoke, has contaminated the evidence of this argument! Lol

[@woutmoerman711]

Jason, this is only partly correct. The alpha particles can't be measured, true. But there are photons too and those can be measured. It shows these rods are slightly radioactive. But they also contain heavy metals.which probably causes a higher risk than the radiation. So don't inhale the dust if you grind this stuff.

Those inserts in the orange/bronze package (Iscar WNMG432 TF IC806) are incredible! My team and I use those almost exclusively for roughing Inconel 718. Also, you may already know this, but the CNMG style inserts may only have 4 cutting edges in the 80deg geometry, but they also have 4 cutting edges in 100deg geometry. You can use the 100deg for rough facing and rough boring if you have the correct tool holders. You can really get your money's worth if use all 8 edges!

Yep, carbide demands horsepower. I used to have a couple of machines and it’s amazing how much material you can remove with 62 kilowatts at the spindle, also how much damage can happen really fast if things go wrong.

Hi Tony, years ago I had a job sharpening carbide cut off tools for production machinery, the flat surface would wear into a dip throwing off my angles, I remembered you never sharpen steel on a diamond wheel because it would pull the diamonds out of the bonding material so I used it to my advantage, I dressed the wheel with a block of steel to wear the wheel flat again and it worked good. remember "If it sounds stupid but it works, it's not stupid".

I had a Miller Diversion and the Thoriated (red) worked well for steel and the pure (green) worked well for aluminum.

The zirconiated were not easy to get here (they had to come from across town and took a half day) so I may try the lanthinated next time.

[@thomaswhitten1612]

I was a machinist for 20+ years and now a FabLab manager. My opinion would feed more I like about .03 inch per rev for roughing it will break the chip better. I think the key to turning is chip breaking roughing passes, leaving .010 then finish.

[@MorganOliff]

On the insert cutters: I'd love to see your results with a little water based coolant just on the heavy cuts. We do this at work with a squeeze bottle . Your lathe might bog a little less. I think it contaminates the micro-welding that happens and frees up some spindle torque. Thanks for the good videos, you're on my "watch at home with the kids" list. :) they love it. Haha.

+Morgan Oliff Thanks Morgan and thanks for watching!

[@erichumann8058]

I had the same question. Would the coolant also work as a lubricant to help the lathe handle the load. When I did that for a paycheck, the only time coolant got used was on chromed shafting. I was unaware that I should have been putting the screws to it more.

[@thatguyontheright1]

Thorium is relatively stable and only emits alpha particles when it decays. Some isotopes of thorium are beta emitters and those are the ones you need to look out for. Doubt they use those in welding rods due to a relatively short half-life. It's likely Thorium 232 and more toxic as a heavy metal than as a radioactive material, like Uranium.

[@johanneslaxell6641]

I'm sorry but now we go metric! With my limited 25-year experience I use ~100-150 m/min surface speed. That gives ~350-400 rpm at 4" diameter. Mainly I use only one grade, one chipbreaker but different styles/sizes. Mostly CNMG or TNMG. Then turning hardened needs ceramics or good stuff. In my opinion the function of the chipbreaker correlates with the tip radius. If I would have the need/possibility to make a shop at home I would do some research: - How big is the lathe/mill? - What will I mainly work at? - What is good toolsize? - What type of insert is mostly usefull in different applications? Left/right and inside/outside. When all this is done I would start looking at toolpackages. My guess is that I would end up with three types of inserts: rhombic CCMT for inside turning, 35° VNMG fof the "fiddeling" and then WNMG for "roughing". If time isn't that important remember that 3*1mm is just as much as 1*3mm, but the stress on the machine is much greater with the deeper cut. Then the disclaimer: my thoughts are based on using machines standing on the floor. I have no idea on what works how on a benchtop machine. We only use shaft size 25*25mm on outside tools and up to 32mm on inside tools. Have fun, be well and keep safe 👍🏼💪🏼🤗!

Hi Tony, I agree, 2% lanthanated all the way. I still keep plenty of thoriated around. Thorium is an alpha particle emitter and is about as safe as radioactive particles get. It is absorbed (or blocked) by even thin clothing. The danger it poses is from ingestion when grinding.

Hi mate. Thanks for the explanation of some of the myths surrounding the carbide inserts. I have used them myself, with very varying results, and was not sure why. Perhaps erroneously, the carbide inserts would be the first choice for beginners, because one does not need to be able to grind a HSS blank, and therefore be able to start straight away.

[@shenyathewelder9695]

I’ve found that stick and tig are Basicly all you’ll ever need as a welder. 4mm and up, especially outside the shop or where structural ability is important, go for stick. 15mm and less, especially where you want looks, no spatter, or need to do things like brazing (my personal favorite), go for tig. Personaly I use stick on as little as 3mm (1/8 for imperial) and I’ve found it’s fairly easy. If you use a 1/8th 6011 on about 75 amps you can weld 1/8th material. I was trained on metric and imperial, so it lets me do silly shit like “you need three inches, and like four millimeters.”

I've heard (I also tend to depend on HSS for most of my turning) that you need to bury the corner radius (cut as deep or deeper than the corner radius) to make the chip breaker geometry work properly. Maybe looking for a smaller tip radius on the same Trigon inserts would let you use the same heavy insert holder for your finishing passes.

[@manofausagain]

Peter W. Meek spot on. Cut depth should be larger then nose radius.

[@Panzax1]

+Joe McIntyre my pleasure, thanks for watching Joe!

[@kevindakilla]

Dunno if someone else commented on this, but it's not very necessary to true the dressing wheel. It will true itself when you contact. Our wheel dressers wobble visually when you mount a new wheel but that lasts only about 0.1 seconds as the action of trueing consumes that material. Also, what will help is frequent dressing with a dressing stick or something. This would not change the geometry of the wheel, so if you start getting taper, out of round, and or radii it won't help you. But it will declog the wheel and lead to better cutting action and cooler part surfaces. And to avoid making a second comment in the other video, gashing is indeed usually done with an angled wheel, and a sort of common practice is to have your gash just barely kiss the very tip of the corner (dubbing) to increase corner strength. On a small to no radius tool, this will show up as a very very tiny shiny spot when looking at the face of the cutter, like a twinkling star.

I’d be awesome if you’d do a very beginner video. Like set up or your welder then what all you need to weld, then slowly work into welding tips v

Thanks for the insert knowledge. Your finish with them at 10 thou per rev, is greater than my HSS finishing tool at 1.7. And, I would have to run it at like 200 RPM max on that piece. I don't like my spindle that fast though. So HSS for finishing isn't good for me.

A brake style dresser is what you use for that wheel and it takes a hot minute to true one up. You'll likely take care to not clog the wheel up after you true one for the first time. 😁
