just have this old tony karate chop it flat... seriously though, that is an impressive cast, can't wait to see you surface it.

I’m all caught up to recent videos, I’m excited to see your plans and I pray you get the dream workshop you want, most high God bless you

This is the content i love!!!!

cement and motor oil sand is used for many years for silversmith sand casting traditionally here in Iran. the perfect ratio (in volume) is 1 oil to 5 cement, don't forget the sieve two or three times the cement before mixing. mix them slowly and gently just by hand for couple of minutes. you can use it over and over again without any problem.

Also I'm interested to know how the CO2 can react with buried substance. How is it not blocked by the sand and solid that's formed on first contact and manages to propagate the reaction deeper? I know I could look it up but I'm lazy 😊 If anyone feels like explaining, feel free!

What are the consequences of pouring aluminium that is too hot? Shrinkage? But if you have excess fluid (risers) won't the part solidify from the outside in and draw more fluid in to replace any volume lost due to heat shrinkage resulting in the same result?

I used to work in the casting industry. Overall, great job! However, I want to warn you against machining into any of the surfaces too deeply - I didn't see you bubble nitrogen through your liquid aluminum to drive entrained hydrogen out of solution. While not bad on its own, you'll find that the casting will have waaay more porosity than you'd think in those thicker areas, and is probably the reason for the porosity defects you noticed.

That's a cool part. And absolutely amazing to do that as a DIYer. But aren't these normally cast iron? Cheaper, heavier, all that

The casting was pretty impressive, but forget about aluminium for a lathe base this size. Cast iron is the choice of material for this purpose not because it's cheap, but because it needs weight, wear resistance and rigidity. Aluminium doesn't fit any of the criteria.

Tragic spelling mistake. For English in all non US territories such as the entire current and former EU including Latvia it's spelled Aluminium ;-)

Did you prepare those aluminum ingots yourself? What is Grade # 1? One heck of an endeavor! It came out great!

How about a video, even if a really short one, on your new bigger furnace? Commercial? Or DIY? In either case details would be great to know.

Really educational how much absolute tradh came out of the absolute tradh that you put in (re grade 2). :-D re grade 1, I think you could have done a little better in 2 or maybe 3 ways: 1. Clean the materials of organic substances and other crap eg light sand blasting or degreaser depending on the contamination. 2. Don't mix diecasting alloy with casting alloy, not the same AFAIK and the mixture is undefined. 3. Feed nitrogen or argon into the crucible through a ceramic tube while hot, without oxygen no oxides can form - this is very much the maybe since turbulence would minimise the effectiveness if it would even help at all. Neat process though. Big gear for a home shop, inspiring. <3

Why did it keep breaking up

Nice job. Consider lapping the lid and top of main part together or with a concrete stone or something to make them flatter.that way they'll seal better and keep you and your things nearby off to the side cooler.

This video did exactly what I needed. :-) nice way of telling your fans <3

Nice job. Those look strangely familiar ;-) that's not a bad thing. <3

Awesome job, man. I wonder if you could have preheated the entire thing to assist in the travel problem. Doesn't matter, it's out of sight and of minimal structural significance. Impressive home setup, Impressive furnace, subscribed liked and will be reviewing the back catalogue.

Aren't Taig lathes aluminium b9x section filled with concrete

I can hear the screams of a thousand reloaders crying out all at once 😂

Amazing job, congratulations. Not a beginner are you?

MyFordboy would be proud - epic casting

Mudied the aluminium surface to film better? Wow that's a first I ever heard or seen such a thing. I don't think there's a need for that :D

it would be easier to make of wood

So i have to ask with a pour this big why wouldnt you try and preheat the mold ahead of time in some form?

for surfacing, you just have to make two more of these and then rub them together according to the three plates method. easy peasy! (seriously though, this is amazing)

I just found and subscribed. While Aluminum is not my first choice, I think you will get some good use out of this lathe. Looking forward to seeing this lathe come to life.

Aluminum is soft and lacks rigidity. I like it though looks nice.

Amazing!

It's a fantastic result, but that doesn't change that it is the wrong material. You will find out when you are machining why people are saying this. All the encouragement is appropriate and well deserved, but none of them have actually used a lathe to the extent that they understand the materials used and why they are necessary. It is still a great job and great experience with such a large casting. Well done.

Dude, results speak for themselves. ANYONE saying ANYTHING negative about this project has NEVER tried to do something this awesome. Keep going.

Light weight lathe, for when speed matters

That's one spoon that you don't want to lick.

Are you worried about the ways being too soft??

Dude, f*k the haters. That’s the largest home casting I’ve ever seen, and it came out much better than I expected. Me personally, I would probably weld steel than pour aluminum; but, I’ll definitely follow your journey and see where it takes you.

oh this is going to be good, subbed

Of all metals, why aluminum?

Requires argon gas bubbling to remove hydrogen gas. Hydrogen gas precipitates as bubbles as the aluminum solidifies. It causes a porosity.

OMG

Really great work!

No way man I used to watch your videos 7yrs ago as an 11yr old and now I was planning on building my own lathe and I come across you again

Wow! 👍👍

Great awesome job, what a size !! Thanks for sharing

Nice size !

I think you should do the opposite first pour the oil and then pour into its slowly the cement. that way you will not have that much dust and you will not have that much problem because it will be absorbed into the oil and I think the system is good maybe you should try to improve it but it does look to me like a very good way

Man, just lifting 70kgs of molten aluminium is nuts. Epic job!

Of course lathes are not made from aluminum because of it's poor thermal stability and damping properties. Best of luck.

Impressively done. Make sure the ways are leveled and machined to the best tolerances you can get before using it or you’ll end up with inaccuracies in the spindle bores of the machines you’re making.
