Your work is amazing!

Very impressive. Optics to thermal imaging to Kodak to UBC. Great stories i read about you. Got me confused, spending time if you can afford around basic instruments and machines. if you can express your thoughts in advanced math with videos in RUclips so we can enjoy more from you

are you saying you cast an LP using a silicone mold and it worked? I'm not saying it's impossible but i feel you would need such low viscocity silicone to flow into the grooves that the silicone would not be able to withstand the heat of thermoplastics. Thermoset resins maybe but the low viscocity silicone is so weak it wouldn't be very repeatable and something like polyurethane resin would probably shrink to much to be reliable. (i love your videos by the way you're my hero) i was lucky enough to work with some vintage vinyl presses, the EMI 1400 incase anyone is interested, EMI headquarters would use a special lathe to cut the grooves into either aluminum covered in acetate laquer, or copper. I believe the lathe cuts with sapphire. From this, industrial magic, not really sure but after some process negatives were created in Nickel using electroplating. These thin Nickel negatives were sent to us, protected in peelable plastic then a spray with compressed air (dust) and put onto the top and bottom stampers which were giant harderned steel flat surfaces (record shaped). The nickel would get bolted in the center and tightened around the circumference with a large threaded ring. PVC pellets would get vacuum sucked into a auger and extruded into a handful-sized plastic puck. The machine then pushed the oven dried paper labels into the top and bottom of the puck whilst also picking it up and placing it in the center between the two stampers. The stampers had low pressure steam running through internal pipes very hot, they would close together (i think also using steam power), and pause to allow the PVC to re-melt at this hotter temp, i think then the stampers closed together slowly to the final position and paused to allow the pvc to flow into the grooves. The steam in the stampers was replaced with cold water, they would open and the solidified record would be stuck to the bottom stamper, where a hot knife would slide in to the edge and the stamper would rotate, cutting the trim. It would pop up and a linear axis would transport it to a rotational axis that gave it a guided drop into the inner sleeve then another guided fall onto the stack. All the axes were pneumatics with compressed air, the 'end stop' was to smash into the end of the axis and remain smashed And before anyone corrects me, I know the nickel negatives were actually called stampers and the giant heavy flat surfaces they bolted to were called moulds but i hate that terminology

I want one

+++ never operate a drill press with gloves (close to the drill) +++

@dgelbart Is that the bed of your air bearing lathe in the background, it looks like the granite T blocks you made for yours with those white bolts (would love to know what those are or where to find them. Id like to try my hand at making one myself. It would be awesome if you would do a more thorough breakdown and overview of your beautiful lathe.

Excellent presentation. Working at micron precision is probably the envy of tool makers. However, this is far from the finest precision in commercial use. The likes of ASML - Zeiss make components at the nanometer or better levels of precision on a routine basis.

Will you share the mechanism used to achieve this accuracy in X direction , the encoders implemented, and the servo/stepper drivers ?

I wish I could have worked for one of your companies Dan. Fantastic to have you as a master at least like this at a distance. Nothing can replace experience in the learning process, and I can only thank you for sharing this experience with all of us !

I so love listening to this guy

Out of curiosity,what is the square foot of your shop?

We would love to use this footage for our feature film! Do you have an email address we could refer to for a collaboration?

Actually tape worms works well for loosing weight. A lot of side effects might put You of slightly.

The scientific community is not always nice. Ask Lize Meitner.

Hello, I just came across this channel and am amazed with your precision workshop and your knowledge. You remind me of Q from Q Branch in James Bond 007 Amazing!!! I will definately be checking out all your other videos. Best Regards Sir

There are now two much better (and much cheaper) ways to 3d print metal than sintering. You can cast, or print metal directly

I think a rotary deburring tool might work great for press tooling.

Thank you Mr. Gelbart. You are the best teacher one could wish for!

WOULD IT WORK TO CALIBRATE WAYS ON A LATHE TO USE A LASER AND A FOLLOWER THAT RIDES THE WAYS AND GRINDS THEM TO FOLLOW THE LASER. OR WOULD IT WORK TO GRIND A REFERENCE SURFACE ON THE WAYS TO USE THROUGHOUT THE MACHINE'S LIFE FOR A FOLLOWER TO REGRIND THE WAYS?

This is the best series of videos anywhere on building anything!!!

I wish you explained the aluminium-alloy casting a little more in depth. Obviously you can't suck the molten metal in using the vacuum. At least it seems dangerous to me. So would you pour it in and then degas the package afterwards? I really wonder if there are any benefits to the vacuum suction method anyways. I don't really want to drill a hole into my chamber to test it though.

Hi Dan. When is your next video coming out? Every few months I check, but nothing for a while... But I see you are still active, replying to comments.

@dgelbart Hi Dan. I am very interested in the cylinder and piston self-starting air bearing you demonstrated at @1:00. I would like to purchase one if possible. Please let me know if you can help. I am located in Northern California! Thanks so much for your helpful videos! I realize this video was almost 10 yrs ago, hopefully you can still help!

I am indeed impressed by your workshop. Moreover, Im awestruck by your knowledge. We should all take adopt your commitment to excellence. Thank you. Please continue with the videos as they are educational and inspirational.

can i just use a big granite surface plate as bed?

I am speechless, this is possibly the best personal shop I've ever seen, just the sheer precision thoughtfully placed into every object in there speaks magnitudes of you as a person! You are like the final evolution of the little demon sitting on my shoulder during every project, pleading with me to make my part just that much more precise and hunt down a few more zeros, however... you actually got there, everything in there allows you to actually get to that level of precision reliably. Hats off to you sir, for you have built the home shop that every engineer and machinist around the world has wet dreams about! Thanks for this fantastic tour Dan! I am now going to go sit in my shop and ponder a few of my life choices... and potentially invest in a bit more granite.

You have a beautiful shop.

Hi Dan, greeting from Australia. I’m in the process of mounting my bench top mini mill in my small garage workshop. I’ve been overthinking bench tops as one does. Just wondering about your timber bench tops - what timber did you use? I’m assuming everything was thought about carefully, having the timber’s laminated running horizontally etc. Thanks in advance

I m interested what is price nd place

A bit too slow for me. That's why I didn't attend UBC

18:33 4' atek bantam air brake with the Apocalypse Now sound effects.

you are awesome Dan, you helped me learn with your videos. thank you

There seems to be a lot of Semitic backbiting in the sciences since time began! It's in their biblical propaganda. In their dna.

What I am missing in this video a bit is what this workshop was built for? Looks like a zoo to me.

This is very interesting Dan. Thanks for sharing it with us.

Wow, thank you

Thanks from another appreciative viewer of your videos. I hope you get the time to make more in the future. Apologies if this has been answered previously, but how did you establish trueness of the spindle axis with the ways? Did you bore the headstock using the ways, do some really finicky alignment or something else?

Did you build the capacitive sensor yourself?

Thank you Dan, I like the video a lot. Community, if someone could recommend me other video like this I'd really appreciate it.

I need this. Specifically, I need single point diamond lathe cutting of paraboloidal, hyperboloidal, or ellipsoidal shapes in 6061 Al. The parts are about 2mm at the large end, 1 mm at small end and about 70 mm long so they resemble very long thin cones. Because they are so long and thin, they must be held at the tail end while being cut so they are under a very small tension during cutting. After cutting we will coat them with 6um of electroless Ni and superpolish with diamond powder to a surface finish of 10 angstroms rms. These are molds for grazing incidence x-ray mirrors so accuracy is needed.

Hi Dan, would a jig borer work for milling or finishing of soft materials such as aluminum, graphite, or plastics? I'm thinking about how the amazing precision of these gantries might generalize to things besides hole drilling Thanks so much for the wealth of knowledge in all of your videos, I've re-watched them many times!

Please make more videos!

In the first shot, behind you on the left: is that assembly from your air-bearing lathe? The two granite parallels are glued to the white (stone, marble? ) cylinders? Or are those simply white plastic covers to protect the screws from water? I cannot see the orthogonal granite spacers clearly, but maybe these are inside the white cylinders? Thanks for the great series!!

We've all seen laser crosshairs, but this rotary laser center finder is amazing. And I thought 3d tasters were the thing ...

Dan, thank you so much for making these videos. I've been working in hardware prototyping for the past 10 years and I keep coming back to your videos finding new things that just blow my mind. Hope life is treating you well!

Hi Dan, if you even need an assistant, I'm more than willing to help and I would also like to learn from you. PS I'm in the same city as you.

Hey Mr. Gelbart. Glad to see you’re still commenting here. Want you to know just how much i’d Really appreciate seeing some new videos. Anything. We’re desperate here don’t make us beg

Would be absolutely great to hear more about how you started Mr. Gelbart! You are an inspiration!

I like how the Moore mill is this precision machine yet has a Jacobs chuck on it :D
