This is such a great video - it's a really fascinating process, and you did such a great job with the voiceover! Thanks for helpin' Crafsman bring the Pocketnaut to life! xoxo - Volt
I came from Craftsman's video, and this was super interesting! I really appreciate how you covered multiple approaches in how you handled the undercut in the mould.
A top notch video and a perfect example of a manufacturing collaboration done right. We need more of this within the small scale manufacturering ecosystem. Desktop manufacturering can be a truly frustrating endeavour due to having so many potentially great project ideas,yet no way to actually get them manufactured. Very much looking forward to the follow up in part 2. Stroke of genius with the undercut mould insert,It just go to show that with a little ingenuity most manufacturing obstacles can be overcome.
Thank you. I have used inserts before, but I think this is the first time I used a press-fit that required this level of precision. It was very satisfying and gives me the confidence to do this more often.
It was definitely very satisfying because I didn't know how it was going to turn out. The theory told me it should work well, but you never know, right?
Super cool project, my one question is why not start with a piece of round stock when machining the insert, it would save a lot of CAM labor and you wouldn’t have to deal with the tabs
This is amazing. I bought one of these. The cost of making a mold like this is a question I see a lot and would also like to see answered. I’ve seen a lot of various pricing online and it’s a little confusing.
Well Done John! Impressive surface finish. I always wonder how you manage to mold without venting. I find it very hard to mold without including a substantial vent on my manual desktop IM
I go back and forth on adding vents. In this case, both the TPE and PP flow easily, so vents are not critical. For ABS, it would probably be much more important.
While making the instert, why didnt you use stock from aluminum rod? We generally mount lathe chuck on mill table and use it to hold cylindrical parts.
Nice colab... We get all the process from different content creators... This was a very nice job, john. ... Also nice timing from both of you... For info. It would be nice to go in to detail, regarding controlling (hold time)speed and pressure..also the limitation of your pneumatic compressor and so on.
There isn't much to it. For pressure, if you have too much, you'll get flash or a blow out. If you don't have enough, it will be a short shot. As to holding time, It's usually not that long as the gate will often freeze after a few seconds. But clamping time might need to be longer to let the part cool enough. In other words, trial and error... As to the compressor, I'm using a 5 gallon, 225 psi Dewalt compressor. Works great for these small machines, and allows me to go up to 140psi to the ram. Most compressors kick in to refill the tank at pressures below 140psi. I rarely go that high, but some molds with thin parts require that.
How much did this specific mold cost the customer? I ask because it is impressive how they treat this type of information as a state secret! For enthusiasts like me, having no idea of costs makes everything quite frustrating when analyzing entry into this type of activity. Thanks!
Great video! Have you been using the Morgan press? If you don't have "Brave or stupid" moments you are not growing your skillset. Still made me lol though. Think we have all said that a time or two.
I haven't used the Morgan recently. I have a project on the backlog that requires it, but I'm trying to work through my backlog before I start on any more projects.
Hello John! Do you think it would be feasible to make a mold of about this size and quality, without the complications due to the overhang etc, using a hobby-tier CNC machine? I live in a very remote place where logistics about double the price of many niche hobby products for us and I'm seriously considering learning milling to produce some simple things for the community locally.
Hello sir good morning Actually recently i design a product with ABS material everthing is okk but in chemical test (acetic acid) it crack so is there any solution of this issue except adding forming agent. If you know any solution than please give me
How do you handle the crazy stickout of your endmill at 7:28? Looks to be greater then 4x the diameter, aren't you worried about tool deflection at that point?
Yea, especially the super-long reach 1/32" end mill. It's about 1/2" long, which means over 16X. The trick is that I use G-Wizard to calculate feeds and speeds, and it has a deflection calculator I use to ensure deflection isn't an issue.
While it's called a coolant, it's primary purpose is to act as a lubricant. Aluminum is a "sticky" material and tends to lead to chip welding. In other words, the chips tend to stick to the end mill. The coolant both washes the chips away and reduces this tendency. It's actually a lot more important for aluminum than steel for that reason.
I like the Crafsman. You helped him keep steady craftin, so I like you too.
YES!💜👏👏👏👍👍👍
It’s nice to see two of my favorite TH-cam channels collaborate.
Thank you for putting me in the same category as him!
Sent from Craftsman's video. Great job on the mold!
Edit: I would never have thought of using a push-fit insert to do the undercut. Again, great work!
Thanks.

Cool to see this collaboration! Great detail on the mold making process. It will be fun to see how the final parts turn out.
Thanks for sharing valuable knowledge. It's satisfying to watch your projects

This was super cool, to see how you aproached the problem and that press-in solution was so satisfying when it went in without any issues. Great work!

Can you say, Genius Level? This was fascinating and man do you know your stuff!
another great video
i hope you, crafsman and lns technologies collaborate more in the future
Thanks. That would be fun!
Sir i request you to please make a video on different techniques for making undercut features in a mould. Your videos are superb.
The Crafsman sent me. And now I've subbed. :) Nice work! Aloha
Thanks for the sub!
Super cool project, my one question is why not start with a piece of round stock when machining the insert, it would save a lot of CAM labor and you wouldn’t have to deal with the tabs
Thanks for partnering with the Crafsman! Great colab project.
amazing
Love the Craftsman channel,! Now I love this channel tooooo!💜💜👏👏👏👍👍👍👍👍
Great video. Man, have you moved to a whole new level since I first started watching you. It’s been a pleasure.
Thank you. I sometimes think back to those times and am amazed at what I did with how little I knew then.
this is so cool
Excellent job
This is amazing. I bought one of these. The cost of making a mold like this is a question I see a lot and would also like to see answered. I’ve seen a lot of various pricing online and it’s a little confusing.
Beautiful, wonderful and very interesting. I appreciate the amount of effort you put in
man is a genius, i wish i had a shop at home.
Great video John! I have a question - I didn't see exhaust air channels - where compressed air from mold goes?
the face should be an airtag
Would it be a good idea to provide a way for the trapped air to escape when you press in the insert?
That's a good point. It probably would have been a good idea to drill a hole through to the back. Thanks for the suggestion.
TheCrafsMan SteadyCraftin!!!!!! Yay!
Great work 👍👍
Great job John. Awesome work!
Thank you!
Great vid John.
Several problems and ways to overcome them.
A sneak peek at a new product, I hope sells well.
Be well.
In his video he said he made 500 and his on-line shop says out of stock--more coming soon. So sounds like it's doing well.
another great vid, keep up the great work
Inspirational to see your process, thank you sir!
My pleasure!
Great vidéo ! Thank you !
Great work as usual, John. Bonus that you got to work with Crafsman!
Very interesting, thank you

@@JohnSL thank you. I will try some different things.. to see where each parameter lands.. i guess experience. 😀.

I wonder how much would this machining cost tho.

@@JohnSL thanks for sharing
👍👍👍
now I understand why lego molds can be so expensive
How can I get in contact with you about making a mold for me if possible please?🙏
How close can the speed of your spindle come to the theoretical speed required for micro tools? At what RPM do you work in micro tools?
Crafsman!
Is the water cooling really necessary for aluminum milling, even if I go super slow?
While it's called a coolant, it's primary purpose is to act as a lubricant. Aluminum is a "sticky" material and tends to lead to chip welding. In other words, the chips tend to stick to the end mill. The coolant both washes the chips away and reduces this tendency. It's actually a lot more important for aluminum than steel for that reason.
is it possible to use a bigger mold then your machine can inject however preheat the mold with plastic pellets then finish with an injection?
Also what is the expected shrink rate?
А почему бы вставку на болт не посадить?та сторона всеравно будет не видна
Hey John…are you the actual Crafsman? Haha
I have to ask: when you spoke to the Craftman, did he used his human voice? 😂
Awesome collab!
Thanks. Email correspondence only. He was really great to work with, though. He definitely knows what he's doing.
how much do you charge to make a mold like that?
11:57 machinging
Woops.
What CNC are you using to make the molds?
