Why is it that everyone who owns a surface grinder refuses to help people out who don't? Ive been begging everyone to take on the simple job of thinning out 6 jointer blades. And its not like Im asking for free work, Im willing to pay for the service but it seems that surface grinder owners are unwilling to help.

Hi, By the looks of it that precision level does not have adjustment screws. How is the adjustment performed on this model? Thank you!

There is no scraping on this channel… In some rough machine shops in Russia we do this. By hand! 😅

Love my wife, but usually I go out to the shop to get away from her and everyone else lol 😆 But She would not be very enthusiastic about ANYTHING I made on any of my machines. However, she does come out and hangs out with me as I’m out there playing with my machines (big kid legos) 😊 We are very blessed to have such a supportive companion!

Do i look good? you look like you. That answer was brutal 😄

I watched the ad and appreciated the way you led into it with your ass being big. Keep having a happy butt, friend.

I know this is kinda late and I’ve been thinking about it for a while. I think they Used induction heating to heat up just the thread portion of the rod as it was being quenched kind of a rapid process. Thereby ensuring a Hardened acme thread With very Run out…. Just a thought it’s late and my head hurts👍😹

Digital readouts are neat and all but if internals are out those numbers are well out.

As a standard fabricator and not a machinist I'm appalled at how your drafts are all neat and have straight lines and aren't drawn on the side of a piece of random cardboard you found in the trash. Bravo. :D

I miss the Drafting 😢

Had one about 65 years ago - made from wood - for drawing. The Z axis is a tad disappointing. Wonder if it is practical to modify so that depth cutting does not cause incline on the cutter. Really nice video - thank you.

Hey there, great video! Would you be able to comment on the pros or cons of using metric vs imperial when it comes to machining? Thank you,

Just letting you know, you could have tempered the centre after quenching with the oxy torch. You polish the surface to be tempered and then locally heat with the oxy and you should see surface colours draw across the surface. The colour corresponda with a tempering temp. Straw at 200-210 degC then dark straw then purple at approx 280-degC to blue and then dull grey.

could you try to surface harden it?? i have forgotten the procedures but you can nitrite harden things (basically putting a hot object in hi nitrogen fertilizer) and some other forms of surface hardening . might make it last a little longer ?!? but is it worth the trouble ??? ONLY You can know . Have fun making great content for us

I can't believe you don't close your "4" being an engineer!! 😂

Noone gonna mention the chapter titles?

Oh how wonderful!! I just scrapped my fourth DIY tool post grinder spindle due to undersizing the press fit size for the high speed bearings. Thank you for being so human!!

Good stuff

I just realized that your last name is Sander. Honestly that is a very funny and fitting name for a family of machinists.

How do i get my hands to look like this

Your O2 can't harden corectly in vegetable oil. You need fast quench oil like Parks50 or water (but this one is risky !)

"Made in Western Germany" so that lead was made before 1989, which is pretty interesting

Cool, now make 500 more

"perrrfectc" "hngnnn 👄"

Watching you explaining stuff to your wife and your interaction just made me fall in love with both of you :D great video!

Personally I would have suggested using a better quality tool steel for the lead screw something like EN19/EN24/P20 etc and not flame hardened it to avoid it distorting,,,, but what do I know 😂😂

is cardboad safe for that capacitor housing?

This thing came out so bitchin! Made me feel like I should have been wearing a PAPR just watching you do the brick sanding though lol.

Very nice work man that thing is awesome!

1:01 It's the definition of "Madness" in us more intelligent beings.😉 Definitely need to make another video "WHEN" this one wears out, if only to demonstrate how much you have learned between now and then & how it's supposed to be done. I have faith in you.

Great job, brother. It 'turned' out amazing.

"Not the bad kind" 😂

Why didn't you hard turn it?

Couldnt you just mount yuour livecenter instead of the chuck?

Wait, he’s in Indiana. Hell, yeah.

.

0:13 bent shaft is normal for some

there are ways to remove the warping from that piece after heat treating almost fully. youll likely need a manual screw press tho (or be verry carefull with your hydraulic one and see if you can bend it the other way just enough to be more or less straight. might wanna heat that back up to 250°C afterwards to get the added tension out and you should have a mostly straight piece

If you're going to ruin lots of gear cutters, you best have a gear cutter maker. Such a funny way to see another video come into play.

try H13 (1.2344 - X40CrMoV5-1), my teacher will probably recomend that, he was making scrapper mashines in school and that steel is not only very stable dimensionaly in heat treatment, it can be cryo-trated after final cut, also if 16 year old was able to made good screw with that it means its idiot-proof steel

I am **impressed**!!! I couldn't tell you how many times I've wondered how the heck those socket heads are made, other than maybe forging them when the bolt is headed! I've NEVER seen anyone else even hint at the tooling! Thank you for finally lifting the veil on my ignorance! Also, just for the record, I'm absolutely jealous of the ease at which you guys on YT manage to make running a parting tool look so easy! In the couple of years I had my Logan, I never once figured out how to successfully set one up and get a cutoff! I always had to resort to a hacksaw or occasionally a Dremel to free my workpieces!

When it breaks next week can you show us how to make it better?

Your machining skills and creativity are insane! I'm glad you didn't go insane making something that looks so simple but is actually very complex.

I’m glad it worked out in the end. I probably would’ve went with A2 tool steel the air hardening properties would keep it more dimensionally stable. The reason you probably didn’t see the O1 harden is because of a thin layer of decarb. Also those Rockwell files are horribly inaccurate.

Bruh, I saw the title and im wondering what you mean? The minimalist wallet is already on your phone? Idk man.

Honestly, that finished product looks dang CLEAN! Especially for homemade!

I too, like kebab. You should definitely do a rotisserie for the shop and/or wife. Addendum: I think this is why lead screws are generally ground instead of machined to final spec.

@2:07 Guilloche. You had it right the first time you said it. It's pronounced ghee-yosh

Nice vid but, could you not rush too much the pace? It seems like everything is so rushed to fit into 20 minutes. Don't worry about video length, that's actually a good thing that they long and entertaining :)

Maybe try nitriding next time 😅
