Thank you for grinding the rails. Always found the lapping method to be less precise.

Even carbide can do this.

Great idea! Instead of teflon tape, using a nylon insert, similar to the insert used in locking setscrews, might work better long term. Plunge mill the male threads with an 1/8" endmill about .100" deep and press in a nylon slug.

If to take trepan cutter and shape its tooth as dovetail, and do a small wobble circle with a radius of undercut - it's possible to get dovetail groove fast. This should be the second operation after making usual threpan cut as a preparatory operation.

please machine a forming die for stamping stainless steel baffles from sheet

This was so educational for me. I know nothing about CAD / CAM. I've watched ToT do an intro, but this gave way deeper insight to the challenges and style of thinking that a pro has to become fluent in. It's why I love this channel.

I don't quite understand the indexer. Maybe I'm missing something, but you can't have 1°1' tooth pitch around a circle. That won't divide in 360°. How do they solve that?

Excellent content .. Edge Precision quality..

Dude, great information. great video. Can't believe this is free

More engineers need to watch this!

Nice

What inspection methods does your Quality department use to verify the dimensions of dovetail features? Those o-ring groves look like they would be very challenging for inspection to handle.

I've ground plenty of acute vees for sheet metal bending. If you dress the bottom of the wheel at a shallower angle than the vee angle you want. The corner will clear and the faces can be ground with the side of the wheel. Then to accurately center I grind the oversized block to the required dimension ensuring the vee is central using a pin & dti. If an acute vee does not need a sharp corner at the intersection then a flat at the intersection of the vee will also help clear the wheel when grinding the vertical faces and no angle needs to be dressed on thewheel perimeter. I see a few videos of large vee blocks, often they do not need a sharp corner at the base of the vee as they are not designed for small diameters. Having a flat allows the vee blocks to be far smaller whilst still holding the required larger diameters.

You can tell this guy doesn't know what he's talking about. He said Lego's instead of lego. ;) - Signed, someone who's only ever opened sketchup to see if he could make a better desk than the ones on Amazon... I can not.

This is not related to this video but curious about your oil setup. What oil do you use for flood cooling?

Very nice; i learned a lot…thank you, Adam 💪

Give this man a medal. Wish I figured this out a long a time ago. So useful that zeroing tip. Thank you

do you sell chips to recyclers ? Does that save some cost ?

what are you using for coolant if you dont mind? do you machine a lot of copper? 95 percent of jobs i do is brass castings and ive trying to find a coolant that doesnt turn blue and corrosive. ive used coolants with metal deactivators but the additive is used up very quickly and then i have 100 gallons of waste to get rid of which im sure you know is very expensive to get rid of. im trying to find a good solution but i havent found any and i have been through many many different brands and series in the last 4+ years do you have any of these issues?

counterpoint: the consumer has now seen so many machined or cast items that machining and casting procedures are now routine prosumer culture, you can literally increase list price simply by doing more visible machining because the prosumer does know what they're paying for. meanwhile rarity markets are splitting on many common items: for example you can now get a real D2 Benchmade knockoff for $10 but anyone who knows what D2 is absolutely knows which is the knockoff and it will get to them eventually. be fancy, there's buyers now for fancy.

Very interesting video. No wonder so many smiths just start from finished Caspian frames. Some of those cuts look very annoying/expensive and only make sense for producing at scale. Not a problem if you're designing something for government contract like it was initially of course.

didn't realize that other video got removed, but yeah, TH-cam hates anything in that category of video because of very stupid reasons. it's extremely frustrating because it's essentially the suppression of knowledge sharing.

chamfers are what separate us from the animals

thanks for the upload. i'm curious what the design envelope is for $40 worth of sheet metal

How have you seen this communicated on the drawing?

What software package is this?

“…letter 31 drill…”?

Based on the first 3 minutes. You can tell this is just w hobbyist who thinks he's all that.

Its because its fucking annoying to machine. No more no less lol

the best parts will always cost more, because more needs to be done to make it function as intention. plus mostly paying for the knowledge used than any intelligence or smarts. things aren't hard after all.

8:30 Fly !

Does anyone know where the contact info is for Demuth Tool & Design to reach Adam?

Im really interested in how the Erowa mounted cutter works. Does the cutter orientate itself based on the movement of the material like a plough?

Excellent video

Nicely done sir!

I admire your professionalism and talent. Thank you very much!

Its very interesting coming from 3D printing, very similar and slightly different concepts!

I mainly do 5 axis stuff with lots of organic geometries and whatnot, parts have lots of fillets on them, and at least for me it's easier to make those parts with fillets than if they didn't have them. All the smooth corners makes it lots easier to make good 5 axis paths with bullnose/ballnose type cutters, if those parts had sharp corners then it would need a lot more acceleration/breaking and other issues.

You keep saying radii when it sounds like you are referring to a single radius several times. Sorry, couldn't get past mentioning it. Five years of Latin crying out.

Literally "cutting corners"

Professor Adam!

very informative

It's interesting, fillets are not just the most expensive part of the hardware, but of the software too. Geometry kernels have entire teams dedicated to just developing the filleting tools.

Here's a tip for designers considering a dovetailed O-ring groove: Assembly mechanics have lots of tricks. I worked on.. er... a fuel system, for brevity's sake. When there was something like an O-ring to keep in place long enough to bolt together, a smear of petroleum jelly was great for just making it stick. Whatever your fluid medium, there's likely a bulk lubricant that's compatible. So just get the trepanned groove. ;-)

Im used to expensive tooling, but man 2k for such a tiny vise is still a lot.

"It's not getting done, the mental math" 🤣 Sounds like the ME I work with.

Wonderful video!

The don't make my parts anymore expensive when sent out? Also they are a must for safety.
