- I wanted and rotary table and decided to build one out of salvaged, scavanged, and scrap metal. In this part of the video, I make the table and base and hand scrape them.
Part 2 can be found here: • Scrap Built Rotary Tab...

I promise I'll still mostly make stuff out of rusty junk and not just buy shiny things with your money.

“2 tpi - because I can” is the biggest machinist flex ever.
I really like the way you did the time lapse of scraping. About a zillion hours compressed into 10 sec.
It was a really interesting way to watch the patterns evolve.
@@JeremyMakesThings You also have the wildest rusty scrap metal collection. It is great what you are making out of this stuff.
Wow my friend I did not realize just how big those iron things are. Incredible. You definitely have a new subscription. Duly impressed my friend.
With porosity like that, who needs oil grooves?! ;)
Your projects are great to watch.
That is coming together nicely. Onto part 2!
Love the scraper you built
How the hell have you not got more subs! Found this the other day, have been binging my way through all your videos. Keep up the good work!
I'm glad I've just discovered your Channel, the Scrap parts you found-they look big & bloody heavy lol but you have done a good job 👍👍👍👍👍👍👍
This was great! Going to watch the other videos right now
Wow, that is one ambitious project, well done, and the filming & editing on top.
I'm tired just thinking about it 🥺
Good looking video and channel! We’ll be checking out more of your videos, especially Parts II and III.
I love the way you handled the index marks on the lathe, I'll have to remember that trick (for my own slightly smaller Logan)
Good job brother 👌👌👌
Excellent job man, keep'um coming..
Seems like a future project for you may be to find a way to add a depth stop to the quill on your mill so you don't need to use the knee at max extension like you do. Your solution works, but if you ever need that extra bit of rigidity it would be nice to be working without the quill extended
Holy cow ….. 👍👍😎👍👍
LIKE IT👍✔
"The high speed steel wasn't cutting it..." Nice pun.. intended or otherwise.
Make brilliant thing from nothing,,,i like it
Longer handle helps.
Can ask why you don't welder on the deep holes in the metal .?
I can see why future you has a surface grinder
1 question, wouldn’t it have been easier to surface grind all of the surfaces, to true and square everything up before drilling and tapping, then bolting it all together?
Oh, absolutely. But at the time I didn’t have a surface grinder, and the one I have now is still too small to do it.
@@JeremyMakesThings looks like you’ve got an idea for a future project to post on here. I’m wanting to fabricate my own shop equipment for projects that I want to build, but I’m trying to figure out which one to start with, a lathe or a surface grinder. I’m thinking surface grinder first, that way, everything starts out true and square. Then a lathe, and then a mill. I’m contemplating on if I want to integrate the mill with my lathe. See my dilemma? The gears in my head, just keep turning, and never stop.
T&m looks like an18,000$ rotary table. Lol
Why is hand scraping better than surface grinding or even a fly cutter?
If done properly, it’s more precise than surface grinding, and much more precise than fly cutting. It’s also only limited in size to the available reference surface (ie, surface plate). I would have needed a surface grinder capable of doing 8x12 to do this- which isn’t a huge grinder, but bigger than most you would find in a home shop. Also, on t he bearing surfaces, it gives pockets for the oil, whereas two ground surfaces don’t leave space for the oil.
@@JeremyMakesThings Makes sense and I appreciate your reply. Somehow this is the first time i've seen this technique. New subscriber here.
NYC CNC did a pretty good video on it: th-cam.com/video/Aq3tHyRVNys/w-d-xo.html
Keith Rucker also has a lot of good scraping videos. I’m very much a hack at it and have learned I have a lot to learn about it.
@@JeremyMakesThings Thank you. Interesting. And Abom :) also sadly I think I never have a patience for that, but it's definitely a good trick to know because i don't have a surface grinder at all, but i do have a small surface plate. Gonna test that definitely.
Consider it this way... How was a surface grinder made, or many a machine that can use a flycutter? By grinding stone on stone, by developing flat surfaces by hand, and so it evolved since the caveman making his axes to modern man hand scraping in machine ways and surfaces, as no machine will cut straight without being straight first, and when there were no machines precise enough, we used bloody hands and plates of stone we made flat through more hand work... Its one of those times where moving your hand up and down until you are done is not considered inappropriate and sexual, but is encouraged by metrologists all over the world...
Jeremy said surface grinding does result in flat surface with no places for oil to seep in and continue lubricating after the initial deposit is displaced by movement, that is true, but also consider that a car engine with its shafts doesnt have any groves, but polished surfaces against polished bearings, also remember that it has a powerful oil pump... Its not that surface grinding cant produce as flat a surface as scraping, but it can only be produced by a surface grinder that is scraped in that well in the first place... Also, as Jeremy said, you need a grinder large enough or a mill with the same axis movement for a flycut... Such a flat surface would be a marvelous machine way, but such a machine would require constant lubrication, via something like a Vogel mf5 oil pump or similar, just like a car engine does... I hope you will learn a lot here, as i am not officially a machinist, but after over a decade of watching machining and my own schooling being somewhat compatible, i now own 2 lathes, 2 mills, a tool and cutter grinder by deckel, the s11 and more, only on account of what i learned from people like Jer... Jeremy, i wish you all the best, deeiks, dear buddy, you aswell! Also, Jeremy, is Jezza acceptable?
What is the center how was it made bought ??? Watching this made me really annoyed
