Alway fun to listen to smart people talk to other smart people 😁

Kertosis and Skew. 🎸

A bit late to the party, but Im having an issue with my bridgeport not fully locking.

Sorry, I’m late with the snide comment, but I wasn’t able to watch until now.

Looking forward to the pencil problem experiment 👍👍😎👍👍. Great idea.

Big shoutout to my buddy @Tom Zelickman!

Just liking and adding a comment so Spencer will get a notification will have to check his phone only to find out some Jack wagon from Southwest Missouri has commented just so that he will get a notification on his phone. Jack Wagon🎸

I would have gone with a honeycomb design on the grooving and adusted the pattern so you didn't have little sliver island mesas standing up at the circumference groove.

If the line spacing is not uniform, then this IS important: it means the surface is curved perpendicular to the lines. This can be observed by tilting the optical flat along a perpendicular line and thus rotating the interference pattern.

Great show, as always! If you are interested, there are a few chemical ways to remove the mill scale. The most common is using a solution of sodium bisulfate. It works quite well, especially on heavy forge scale. The section on peel grinding was excellent. I’m going to give it a try tomorrow. I did notice that Adam recommends a maximum of 1/2 grain diameter in both depth and crossfeed. Keeping the depth to less than 1/2 grain diameter might help improve the wheel wear characteristics. Thank you, and keep up the great work!

intention to inform: there are juwlers resin pads. You heat them up and place what ever inside the puddle then you work the piece. When you are done you take a blowtorch and melt the piece out. That resin clinches to almost anything like a visegrip. Maybe you give it a try. The mix is mostly made from pine resin a relative hard resin.

It doesn't surprise me that you are getting a high reading in the middle and low reading at the ends. When you slide the lap back and forth, you're spending more time at the ends than at the middle, hence taking off more material at the ends.

two guys and a ... kilos of white powder cut up and stepped on for distribution ...

Would really love to see you guys approach a new problem!

Hi guys! Great discussion, and I appreciated both of Adam's videos on his art projects! I'm sure it varies by state and city, but as far as I'm aware, there's no limit to the number of art pieces you can make per year. The liability and concern only happens when you sell or transfer them to someone else. Ergo, build and craft away, but only for your own enjoyment, or just get the paperwork and do it that way too. Loveed the discussion, and hope this helps!

How do people engineer entire CNC machines with microcontrollers motors mechanisms and more and then the battery circuit is so incredibly rudimentary that this product ends up being a game changer for 100$ that contains two diodes and two battery cell holders.

This was a great video. This video got me to thinking about Peter L. Stanton’s recent videos. He would be a great guest for the topic of problem solving.

AKA. Liptonite and Moment of Renzetti.

Great content ! Can't get enough of you guy's !

Thank you, I'm learning from the east coast of Australia. The sharing of knowledge is incredible 👍👌🇦🇺

Welcome to "Senior citizens struggling with zoom and hunting microns" :)

Great get together of the inspirational people... as always learned again.

Thanks for recording this, I missed it.

forbidden wisdom

Go ahead pull on that one more time.......

I am blown away by the interview questions. It totally changes my philosophy on interviewing candidates. Thank you Tom.

Slick 👍😎👍

Nicely done, sir.

Now you need to put a reminder in you phone to change the batteries next year or at least I do as I wouldn't look at that stick until there is a problem.

Great conversation 🙏

Sadly. Work says enyrhing with Bluetooth is not allowed as its causes distractions from us machining and dont allow us to hear the machines running. Yet hearing protection is required.

Why not use compressed air around grinders ? I do cylindrical grinding in the aerospace industry and I havent heard that before now. Am I missing something?

TL is the goat. Real mvp

What was the name of the book related to gun barrel precision?

Also, the elephants foot is caused by two different things: Expansion of the resin due to high over-exposure and build plate squish during exposure due to too fast a retraction speed that doesn't allow sufficient time for the resin to completely squeeze out from the 0.05mm (typical) initial gap between the LCD screen and the build plate. Long exposure delay after retraction finishes also is necessary to minimize elephants foot.

I almost exclusively print directly on my build plate with my Elegoo resin printers (Mars 3 Pro and Mars 4 Ultra 9K). I use a chamfer as well, but you have to change the angle and the height of your chamfer to match your base layer and transition layers. I typically only use 1 base layer and 10-ish transition layers and thus you chamfer height needs to match the height of your base + transition layer and the angle is calculated based on the base and normal exposure times. This helps the thickness issue, but to solve that completely you need to slow the retraction speed way down for all the layers, but mostly for the base + transition layers. The details are specific to the resin being used since the amount of elephants foot depends on the resin.

Sorry I missed the live stream - one thing I use all the time is vented screws. When designing anything that bolts together that has to live in vacuum, we use vented screws to prevent those little pockets of atmosphere in the bottom of blind holes from "wrecking" your vacuum. (think big cameras in astronomy)

I hate people with surface grinders and full size tools.

A great Father's Day episode chock full of nerdy details. Very interesting - Thank you

Could you try and get the guy from edge precision, it’d be great to see how he is getting on.

Nice episode 👍👍

do you have a mist collector on that? or feel like it would be necessary to have one?

I enjoy watching Tom. Always!

Thanks for stopping by Spencer! awesome to meet you after following your work for awhile.

After 30 years of milling I will never remember to reach around to activate quill lock lol

Congratulations Sam. Hopefully we will get to see the finished piece. 👍👍😎👍👍

Neato!

Care to post model to Thingiverse or Printables?
