I must say, I greatly appreciate you sharing your failures and problems with us. It certainly helps me pallet my own failures as I am actively starting to learn CNC machining.
John, it would be very cheap and easy to make the knife tray holders out of wood... have you thought about that? I could certainly do it, but you could also have the person who does the SAGA cases do it.
Came here to see some 5-axis machining and automated parts handling. Saw some stills on a phone, and learned how to make an office chair more floor friendly......
Pretty sure john saunders addressed this in a past business of machining episode, i believe he said he doesnt carry his becuase he abuses his edc knives and would feel wrong doing that to a piece of art.....or something of that sort, it was early in the episodes of BOM.
Pretty sure you could cut the foam on a table saw, could be done quick without using the fence and just super glueing a thin rib on the table top for groove to groove distance, like a box joint jig.
Maybe you could find some aluminum baking pans to adhere the slotted foam pieces to. Something like 9989T54 from McMaster. Or plastic ones like they use at fast food restaurants.
I watch these machines and I'd heart in mouth about crashing a Tormach ..let alone a Mori or a Kern... Also the fact you mentioned you spent 100k on tooling in another video for the Kern is amazing but also you could buy like 10 Tormachs..I appreciate these kern and Mori are and your swiss lathe are like top class machines. And heres me about to attempt my first 2 sided ali machining with a homebuilt cnc haha... seriously love the passion you guys have for all this .. your totally killing it :)
Best clip was skye running the lathe working and then you rolling around a office in front of him. I mean don’t get me wrong I do it all the time to my operators. But hilarious.
One piece flow works in some cases. But you need to have a Kanban of material (ideally produced a day ahead). Once you figure out the bottle neck that pretty much can define the Kanban level.
Off topic a little bit John, when you where showing the clamps on your phone It got me wondering if you had a presence on Pinterest by any chance it should have some great benefits for sales as there are a lot of people who are into knives,
Machining the foam for the part trays should be possible to do If you can get a longer flute length tool that can make the cut in a single pass, that way the thin foam walls are supported the whole way along the cut and shouldn't catch on the tool as they might do if you were doing multiple depth cuts
Make it on a table saw, blade forces won’t be deflecting the walls sideways just pulling up and down. Single pass per slot, shouldn’t take more than 5 minutes to make a whole tray
John... You need to focus WAY more on the important things in your shop. The things that make parts. In this video, you told us about the time you spent on foam part trays and collect trays...while NOT making progress on your job. This stuff is someone else's job. Love your videos. It's been fun to watch you grow as a machinist...and now you grow as a business manager. Let someone else handle everything in your shop under some dollar amount...or some manhour-amount.
Why not make some blade trays out of some soft wood like pine? just get a cheap router (hand held, not cnc!) and route slots in it. You could even make them stackable that way. Actually, give the cad to a kitchen company who has a wood cnc and get them to make it!.
In one of your previous videos you mentioned those casters for office chairs. So I went to Amazon and did some digging around and found that 10mm is the typical stem size. The 11mm is apparently the standard for Ikea chairs or something. Anyway I bought some that I thought were better designed because of the bearings around the stem are not a bunch of little balls sandwhiched between some curved plates, they are actual bearings. So far I think they are pretty good. www.amazon.com/gp/product/B07V3HMLKT/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
So not at all knocking your drill bushing alignment method- looks like it works great! But like, you're not the first person to own a Swiss lathe. How do others do it? Surely there's some standard way to get the collet holders aligned?
I believe the correct way would be a indicator in the holder and to sweep it around the outside of the round stock to center it on the holder to the work piece.
Here is my 2pence worth. That spot drill will not follow true,get a bs2/bs3 center drill instead, Get a bigger shank stumpy drill as you are not going that deep.After 2nd part make sure there is stock left for the centre drill and not a hole left by the drill as you will just keep following the drill path and "wander". If your spot drill/drill was "going" that will aid in pushing back the stock in the spindle(hence why it needed tightening and sizes issues)it will also depend on the stock material as it should really be ground bar to controlled dia`s.Only way to properly set a tool is with a dial indicator, your sleeve thing is not accurate enough sorry. It might even need boring to control size/ovality before thread mill. 136 bad vs 8 good not good statistics. Nice chair wheels tho its a hard learning curve and a long one but persistence will pay off. A lot will also depend on machine strategy's and keeping an eye on stock levels on every process. Anyway cheers and keep on going 25+ years in the industry and i am still learning 🤣👍
I just wrote: That sliding collet on the Tornos seems to be a recurring problem. Horrible design. Something that you have to get "tight enough, but not too tight," goes completely against the ethos of machining.
Horrible design? Except that it's not? You just need ground material. Definitely does not go against the ethos of machining, it would be impossible to make alot of parts efficiently without a sliding head/guidebushing design.
I had a guy come to my shop one time and ask if I could make a small plastic gear for his garage door opener. Not my cup of tea. He said he could buy it for seven dollars. I said well i could probably make you one for $1,000. I never saw him again...

Not to mention the extraordinary lengths he needs to go through to devise ways to setup tools 18:48 He needs to design these elaborate methods to center and setup tools. "Put ¼" stock in the spindle, ¼" stock in the tool holder, then slider a drill bushing back and forth..." You're telling me there's no proper method or tool that is specifically to do that? Can't be true. I'd love to know what the actual method that Tornos says to use.
Andrew Delashaw I’m guessing they would recommend using an indicator in the spindle and indicating each tool. That’s how I do it in my Mazak with live tooling. It’s goes pretty quick to be honest. I’m also thinking that we see it as more of a problem because he’s changing jobs so much. A Swiss lathe is really meant to set up and run thousands of parts at a time so more setup time initially is to be expected. Not many shops buy a Swiss turn machine to run a small batch of parts.

Absolutely. A 300 mm Kitamura horizontal (4 axis) with a pallet pool (6 tombstones) would have been running full production by now for just over half the price. Plus you get handy things like a loading station instead of having to manually move pallets to a bench to reload and he could have bought blank tombstones instead of milling out huge chunks of 4140. Sometimes the most expensive and/or complicated isn't the best. Also as has been mentioned a swiss turn needs ground material and 500+ part runs to be worthwhile.
TheGameChanger How does he spend basically 2 million ,or more and then spins his wheels so much? Those machines have to make chips all day. Every day as well ,if possible. Someone is paying. Either that or this guy has family wealth to get things going
You don't need to spend your time on those tool and collet trays- focus on those roller blade wheels for your chair.

Woah that Kern betrayal at the beginning, gimme gimme more!

Your buddy, John Saunders, does not carry one of your knifes (as seen in the last J 5 unpacking). You should solve that.

Dude those clamps are mint!! Nice work! The Rask handle at the end!! Awesome!
Pretty sure you could cut the foam on a table saw, could be done quick without using the fence and just super glueing a thin rib on the table top for groove to groove distance, like a box joint jig.
are you cutting the old hole off of the bar in the machine ? That way the tools will establish a new hole on the next part . Great vid . Thank you
wow those scales are looking good man, it's happening!
Fell down the rabbit hole again, this time it was a promise to yourself to get it cut. Which included fixing everything else first.
Maybe you could find some aluminum baking pans to adhere the slotted foam pieces to. Something like 9989T54 from McMaster. Or plastic ones like they use at fast food restaurants.

You need to get the UMCs working to be able to cut that foam!

Also, it has been awesome since quarantine, the video frequency has been great.
Trust a grown-up car guy to hot-rod his office chair 😂
hi have you heard about milling frozen parts? could be useful with this foam. an interesting video on this topic was on the applied sciences channel

Does John pay himself overtime? I feel like this question would have already been answered in their podcast but I don't know how to search for that.
Awesome! Could you skip lapping on the handles if you face them in the Kern? Would save a lot of labor and expense right?
But you have to debur then after that
Very nice!

Hey John, you sold the yellow Volvo to Skye...but you never said what you replaced it with...do tell???
He said on the within tolerance podcast.

Less contact area means higher pressure.
Everybody even grandmothers make knives and only a few can make nice pens. Please, start producing pens and design a new bolt action one too.
The Swiss lathe seems to be riddled with problems. At least from a viewers point of view.

Office chair wheels don't fit? Million dollar milling robot to the rescue!
Why buy it for 13 bucks, when you can machine it for $400? 😁
