put a 1+ second dwell at bottom of cycle to allow chips to evacuate. you can actually calculate how long it takes the chip to come up and out based on drill twist rate and RPM. otherwise chip binds during retract which creates drag force higher than tensile strength of small through-coolant drill bit which has a tiny amount of cross sectional area.
Hello John, so beautiful to see all the emotions, hard work, trial and error that goes in to developing such a beautiful knife, step by step you really see the heart and soul going in to making something that has been in your head literally for years now, so cool!!
Sooooo happy to see this old style video!
in my experience carbide drills in general don't like like to be spotted and don't like to be pecked. This is because carbide drills (at least the 140 degree ones) are self centering and when you peck the drill tends to chatter on the way back in causing the drill to wear and potentially drilling oversize. If you have to spot the hole you want the spot to be the same angle as the drill.
I can't believe it has been 8 years.
What a great video! I retired 15 years ago. We cut Acrylic on a C&C router for boat hatches. That was before we got a new machine with a tool changer.
About fuggin time John.... missed this. This is what made you great.
I understand running a business is no easy task. You've been distracted. But this is the good stuff here.
Really glad to see you bring back knifemaking Tuesdays. This was always one of my favorite things to see pop up on RUclips. Great lessons from your shared experience. Welcome back John!
I know you don’t want to do the slotting with the larger slitting saw but your argument about the orientation of the knife being down and wasting material and needing to do a second op is nonsense. You have a 5 axis machine it would be machined in the exact same orientation as you are for the high feed
I think I speak for a ll Grimsmo fans, we are beyond excited for the finished product! Personally really stoked to see you walk us through the process! Idk many others doing that! Thanks John!
I love knifemaking tuesdays. So great to see an indepth episode where you show us all your troubles and thoughtprocesses to find solutions. I was so happy to see this episode and looking forward to the next ones to come. Greetings from Estonia.
Why not make them out aluminum to prove program?
We know you'll end up making a fixture to hold the handle upside down after the first upside op to finish the bottom. That'd be a good time to add some lightening holes/features.
I thought i'm only gonna buy a Norseman and that'll be my one and only Grimsmo, but... now i REALLY want this thing. Whenever it's out.
Thanks for everything through the years guys.
"Stay Strong, Chase Excellence Brothers."
- Godspeed
Thanks so much for sharing the process broken tools and all. I had a rough day breaking tools on my Hurco I picked up when I visited your old shop in 2019! Great to see you back to long form youtube videos!
Back here for the first KMT in 8 years! Looking forward to the series.
Yes. YES. YES. MORE. MORE. MORE.
Use a paint pen to mark on the vise nut which correlates with which torque wrench to use. Color coding is easier to quick reference than letters and numbers. I do the same with Allen head screws and the Allen wrenches to take the guessing out. Just my 2 cents.
Awesome to see the new build John. The journey has been amazing and I'm glad I've been able to see glimpse of it in person for almost the past 10 years!
Just watched the whole video in the UK and I hear the tension in your voice and see the relief in your expression? Don’t know why you put yourself through it but it’s a riveting watch thanks👍
Amazing!!!! ...and nice FLEX checking the time on your vintage Longines. 😇🤜🤛
I love seeing this process and level of detail, really interesting. I think many folks underestimate the amount of iterations, tests and minute adjustments that are needed to bring a product (of any kind) together. This is great, looking forward to seeing the final result someday!
I love that making these knives still makes you giddy. 🙂
This is my first time seeing one of these videos I can't believe all the work that goes into this That definitely justifies the price looking forward to more videos
Thanks, John, for the in-depth long format. I love seeing your process and tenacity. Very inspiring.
Quick tip on how to center the piece faster with digital callipers:
- zero on one side
- measure the other
- move either side to half the second measurement
My preference is to have one side as a constant. Then if I'm worried about stock consistency, such as a saw cut, I'll make the tool path run long on one side. That way it doesn't take a big bite on a long one saw cut. I'll set my calipers or whatever im using to a dimension and lock them there. Then just consistently set the left or right to that. Again just a preference.
Nice stuff Bud - love the perseverance and that the attention to detail is still there after all these years
This is where the fun begins
Your passion just doesn’t get any more real. Love it.
Awesome work so far John. Very inspiring, excited to see where this goes!
Seems kind of silly if you have the slitting saw, use it in the 5 axis at a90 and Interpolate between the cxy axis to make your profile. Z would be used to center it in the frame. If you set your g54 to the center of the blank, you could use the slitting saw with c at 90/-90 x at 0, z set to 0 minus half the cutter thickness, and just use y and c to trace out the profile.
High feed mill would achieve the same end really, you would just be using interpolating between z and x to profile and set depth.
Love the opening credits background on the computer!
Super interesting to see this process and all that goes into it! Great video! Cant wait to see the final product!!
Always entertaining. I think you are confused about what the expression, "Eyeballing" actually means. You don't need calipers to "Eyeball" something... You are forever the master of attention to details.
Grimsmo is back! This is going to be the best 3 - 4 weeks ever!!!
The squashed chips are a signal of excessive feed usually, that might be a problem, i also work with osg drills on a regular basis, osg has very good guides on drilling practices, ask your tool rep for them, they have been life changing for me.
Wow that intro music took me back lol. I gotta say you where a big inspiration for me to get into the manufacturing industry. Started watching back in high school and now im over in Europe checking out a new cheto gundrill we are purchasing for our shop.
Have followed you since before episode 1 AWSOME to see this design come to life!!!!
So nice to see another knifemaking tuesday after so long. Back then when I did rebuild one of my first CNC mills, I saw you in the very first episode of knife making tuesday, and followed since. And decided that sometime I will also make a pocket knife with my CNC.
And what a coincidence - in the last weeks I machined the very first blades for my _integral handle pocket knife_.
We're one the same train - looking forward to your next episode!
So happy to see KMT back!!!!
The intro music was nostalgic!!
Imagine going BACK to work at 10pm on a friday night because you're just too excited to wait. That's the dream 😅
The best part was getting inside your head while troubleshooting. Thanks for sharing that aspect of the process.
Thank you for making this video! I watched the whole thing and I thought it was too short, ha. I could feel your satisfaction when you finished it, can't wait for what is next! It's going to be an awesome knife, I want one.
I have never clicked on a video so fast! Yay for knifemaking Tuesdays!
I kept hearing "slitting sauce" and I was not even batting an eye. XD
Yes welcome back Knifemaking Tuesday's
Awesome job John! My guess with the drill bit was the missing retracts too. Nice result ❤
I want so much for you to spend some time thinking about the dust problem in these knives. Best knife ever, when sharpened and reassembled just so. Beautiful deployment, awesome blades. Recently I just had to switch everyone at the shop back to a Sebenza, as we are a millwork shop, and the ambient dust and sawdust inevitably clogs up the Rask by the end of the day, preventing it from opening properly. It’s now a gentleman’s carry for me, but I miss the easy action and lightness every day in shop. It’s quite inconvenient to have to take it apart twice a day to ensure that it opens and closes/locks safely.
You can use a tool for a stop. If you have an extra tool open I have a 1/2 dowel in a holder and program it to a spot and pause program for me to insert the part slide it to the dowel (stop) then clamp vise. Or sometime I will use the diameter of the shank on a tool to. Hope that makes sense and helps. just me two cents
Hey John,
When you have a failed part because of one operation, why not carry on to another operation on the same scrapped part to prove out the rest of the process? Even though the part is scraped you could have still gotten a lot of data before restarting entirely.
Best!
A broken drill bit in the part would have caused havoc on the following tools. Just not worth it.
I had a great idea the other day to do that slit on a table saw (well not with a titanium handle lol)...hear me out....build a clamping fixture out of aluminum that completely encapsulates the blade....two pieces like a clam shell that bolts together.....set your fence, run it through the table saw at the correct cut depth......now go hold it in soft jaws and clean up the inside with a ball nose....of course like you said, you have the 5 axis, and you can do it the other way....but for someone making knives in a garage or small shop, you def can skin the cat other ways
A lot of work goes in making that knife, but I still want one as soon as you get them ready 👏👏👏👏👏👍👍👍💯🔥🔥
Great video 👍 We all learned a lot I would EDM the slot and texture mill finish to taste 😊
Always ground your model in fusion. I’ve made that mistake before as well. So glad these videos are back. I have been watching your old ones for the past month now.
Awesome.
Do a wave pattern on the inside by cutting like a wave instead of straitline toolpaths. Maybe even tilt it like a way as well.
Holy crap I've been watching you for that many years? And I still remember the X2 😊
I am making my own integral and had problems with holding the part stable. Just ordered same vice that you use from Ceratizit I hope that it works out! By the way I use slitting saw with inserts from seco for the middle cut. Leaves very good surface!
Love these type of videos 😍
Even though I think their knives are ridiculously over priced. I still respect johns efforts 😆
Really awesome project. Love to see these kind of videos. Curious how the knife will look in the end!
Saw 5 minutes, watched the rest this evening.
Many thanks.
Awesome !!!
Best caliper tip I’ve ever seen is to use the top flat and the edge behind the screen. Way better than using the stick.
Love the new Grizmoid!
nice setup
I know this forward thinking but I think a grimsmo axe for be a badass addition to the line up very Viking and very cool what you John could come up with!
So you just had to tempt me again...
It looks awesome. Im glad you decided to finish your prototype. Not every knife needs a pocket clip. Honestly I'm not sure i would want a pocket clip on such a classy gentleman's knife.
Welcome back old friend! BTW Shaun Casey
Amazing! Would be interesting to see some closeups of those tiny high feed mills. All I've ever seen are large indexable ones.
Leaving work at 4am like a BOSS
I once said "Clearance is clearance" to myself having watched the spindlehousing, in full rapid speed, literally wipe away coolant that was sitting on the side of a part - without touching it. I nearly shat myself.
You and Saunders made me get my VF2. Loving CNC and making my own custom products! Nice video as always! Been watching since you got the tormach delivered to your garage 😂 that was awesome. Imagine owning a Kern!
I see sandvik boxes! Thanks for the business :)
Give walter titex drills a thought. They are probably the best solid carbide drills on the market. We use them every day. From 2MM up to 16MM, 3xd up to 40xd.
damn, John out here on the grind!
How awesome 😄😄
YES! welcome back
Oh, that intro!!! 🙌. Are you really back, Johnny?? 😄
On centering your stock, make a center tic mark on your vise and a center tic mark on your stock for a faster set up.🇺🇸🇨🇦🇺🇸
If that handle weight bothers you on the first full knife, you're talented enough i bet you could hollow out the inside some with a lollipop endmill 😉
I've been following for over a decade, I'm part of the email list that they offer current knifes for sale, but I really want a Damascus blade. Matt C.
So its a plung style button lock. Wish you would have gone to a compression lock style button lock like the Brown Lock or the Spyderco smock. They seem to have a much better detent than the plunger style button lock.
I think that the Scott Cook Lochsa was the first one-piece handle folder.
But you can salvage the part with a new in progress probing. I can't remember what it's called now in fusion.
That old intro! 👌👌🤘🤘🤘
You've come along way from the old Tormach in the garage :)
-- Mental checklist: "Di-iiid I do everything"?
And I start screaming "PROBING! Probe the part!" =)) But I get that your WCS is probably somewhere on the vise
Regarding centering the part in the kern dovetail vice. Could you just make something the shape of a set square, hold it against the part and the length of the other side hits against the vice. Super easy and quick. No fuss.
A slitting saw with "million little passes" should be much faster for roughing than a high feed end mill.
I'd love to se the Rask with a forged carbon handle..
So, it's an integrask?
Chips arent ejecting. High pressure might be compacting the chips, as opposed to letting the flute geometry to eject them naturally. I'd peck drill. Also could peck drill undersize, then ream, or do secondary drill operation with correct suze to open up to desired finished diameter.
What do you normally run your high feed mills at in titanium?
You could use any size slitting saw you want, the cut depth is only restricted by the radius of your arbor. You have some high end lathes that you could easily make a well balanced arbor, of your own choice of size.
If your slitting saw tool holder is spinning in your spindle, the chances are your arbor shank is already spinning in your collet. If you get to that point, you’re pushing the blade too hard.
Every machinist has blown up at least one slitting saw, get it over with so you know where the limit is, then work back from that.
Price point going to be about the same as the rask and Norseman?
wow
You could do a finish step right after a roughing step to avoid that chatter on the inside, that way stock/stiffness is still there. Im sure you know but your strategy seemed a bit off.
