Joe, at 78 this was the best quickie I’ve had in a long time 😉 !
I would say the majority of your success on what you achieve is planning the task first
Absolutely.
Absolutely! In building, a contractor once said. There are plans with pretty pictures and no details. There are plans with details lacking pictures. But the cheapest way to inspection are plans with both. Get a good architect! It will save you tons of cash in the end. That is so true.
Quick, concise, and informative. No surprise, just admiration.
Nothing wrong with changing plans. I do it all the time :)
Usually after making the part... :)
I never miss your videos. I was in the hospital for three weeks after shattering my leg and knee. I looked forward to your videos while longing to get back in my shop. I finally talked my wife into allowing me to go back in the shop to make a couple of extensions for the outside legs for a shower seat.The way it was set up was sketchy at best. It felt great to finally cut some metal again.At age 69, I know I will have to give it up in another thirty years 😂
@@joepie221 Spot on!
Interesting info,Joe..Keep safe.Thank you.
Short and sweet! Just as good as long and laborious! Woody
Lol... always stay for the end... it's unpredictable.
very good job Mr Joe Pie..thanks for your time
A piece of Pie is never a disappointment, no matter when.
Nothing wrong with a 'quickie' Joe :) Love the step pulley - and as usual, attention to bearing surfaces etc.
Great to see a refresher on these parts, with additional aspects added. I frequently rewatch your videos prior to actually machining - they help get me on the right path.
I go back and watch previous videos just for fun
Man, you're good. Love to see your work and how you think. I learn alot and even if I don't do what you do I still use what I see in other situations. Thanks for all this great videos.
I appreciate that! Thank you. The concepts and approaches I show are very applicable to other setups. Glad you get that as a take away.
Nice Joe thanks for the preview
Howdee Joe, I had forgotten the file treatment I sent is to stop the chips welding themself a files teeth. Yes it does make a physical difference in using them. But no more unwanted scraches on the worked piece and rotation tools stay cutting longer. I do love your style my friend Friction is the killer of tooling and you do your best to make it as little as possible. See you Saturday my Texan friend.
Love your work - totally inspired
The level of precision and art you are putting into each and every one of these machines is a wonder Joe! Inquiring minds are wanting to know when the build series machining 1:100 scale models on these machines will commence. The level of accuracy and precision would suggest these are fully capable production machines once you have completed the micro workshop… possibly even steam powered?
Everyone says 1/100 scale models would be tough. That would depend on the size of the 1/1 model being reduced, right? If in time I do build a diorama and run these, it would most likely be air. Steam would be period correct, but I don't want the moisture associated with it around the cast iron.
@@joepie221 maybe a 1:10 scale panto-router would be needed? is there a PMResearch model of a Deckel FP1 I wonder ?
Beautiful. I didn't see a set screw hole. Is it still to be done? Or maybe there's a different system for this one. 😊
Yet to be done. Good eyes.
I’m waiting and watching for the day all this little machines are all running under steam power.
Joe even HAS a steam engine in approximately the same scale! I've been waiting years for Joe to rig up a shop mock-up, complete with an overhead donkey shaft!
Short but sweet! Did you make the Celcon washers or did you source them from an industrial supplier??
Thanks again
Looks nice , Will you add oil holes to the casting for the drive shaft ?
I plan to add oil cups at each journal. Yes.
That axial gap... Maybe it's there so pullies can self align with the pullies on the line shaft (I beleve this was the name for system of pullies/shafts/belts... on the ceiling, with one central power source, before electric motors came to play)? Flat belt on the crowned pulley tend to self align itself. And the force that move the belt to the center of the pulley, can also move pulley to the center of the belt if pulley is free to move. So if the machine and line shaft pulley are not perfectly aligned, it will self ajust.
The pulley is locked to the shaft, and the shaft is pinched on both ends. Maybe its for a physical hard alignment??
How are you going to find a steer small enough to make leather drive belts from?
Miniature cattle are a thing.
@@danharold3087 1/24th scale? I’ve seen the ones you are talking about, though - cute little buggers.
@@Reach41 Really can't say on the scale. They are cute. Cows can be quite friendly. Bond if you spend the quality time with them.
Very good video Joe. As i have said in the past you should have been a teacher.
Hey Joe, ever think about making simple thrust bearings for something like this? It would be simple, but would it be more effective? Just out of bronze. I know they use them in turbine generators and they last for years, just thinking...😊
How would you workhold a steel ball on a surface grinder to create a flat safely? A drill vise with soft jaws with cup recesses with vise on its side? That is my best guess.
Balls can be held in many ways. I cut a fair amount of aluminum balls for my dive platforms and a collet works just fine. A square collet block in a vise is one method for milling or grinding, but that depends on the diameter of the ball of course. 2 thick washers with large countersinks makes holding spherical objects easy when sandwiched, and when all else fails, drill a hole in a thin plate and clamp the ball into the hole. Flip the plate over and hold it in a vise to expose the part of the ball that passed through the plate. Just keep the hole in the plate smaller than the diameter of the ball and it will seat nicely. Just thoughts.
Thanks just thinking of all the catastrophic ways surface grinding a one inch stainless steel ball for a large flat may go. Obviously light passes but hard spots, grippy spots and heat expansion are things I am concerned with. My drill vise on it's side is chinesium so my fears start there. If I use too much grunt it may shatter, not enough and I create a stripe. Thanks for your time.
love your Mid Week Quickie, better than a Nooner....
Behave yourself Paul.
MERCI
Hey Joe, I have a question on the ridges that the belt would run on. It's looks like they're concave(or rounded off). Is this an optical illusion or is that true? Also, wouldn't it be better to have an opposite curve in them so the belt wouldn't "run off"? Just wondering.
Belts run to the high spot, so two crowned pulleys will ride the belt in the middle.
Each region of the cone pulley is a domed profile at 1" radius. I believe thats called convex.
@joepie221 ok...I get mixed up on concave/convex, I just know when u try to put a new saw blade on a bandsaw(I know this isn't a bandsaw, but same principle) the wheels that the blade runs on have to be perfectly aligned for it to track. I couldn't picture a belt tracking like it should without a v groove in it...thanks for the vid...
@@timothypowell5687 concave... think a cave goes inwards - simple? Of course you could do it the other way around if you wish, just think... convex... I am vexed at that speed hump, slows me down.
Yes, the pulleys are crowned. You often see crowned run surfaces when flat belts are used. It allows them to track correctly. I have a few machine tools that are full size. They all have crowned pulleys.
Machinists: turning dull metal into shiny metal. Because, nice and SHINY! 😄
Shiny is always more fun. Especially when you start with a turd.
In doing three phase work on my old shop, an electrician taught me that, when working hot box, NEVER touch anything shinny. 🫨🫨🫨
Second time you've mentioned "silicon" washers recently, you sure those are silicon?
Celcon, not silicon. 2 completely different things.
@@joepie221 my ears aren't what they were🤔
@@2lefThumbs You should remove the silicone ear plugs🤣
👍😎👍
Lol , already had a mid week quickie ! 👍
🤣🤣🤣
✋🏼🇦🇺👍🏼
... that's what she said! 😂😂😂😂
Yeah that’s the joke.
mid week Quickie.........OH! were talking about machining
Once again youtube has unsubscribed me, they must think I want to learn about machining small parts for ? pew pew fools
