Something not mentioned, but is a great idea that it looks like you've used: It appears that the dowel holes in the part are offset slightly from the centerline of the threaded hole. Poke yoke...it can't be loaded backwards :)
Love that you called this 'knifemaker style' fixturing lol. I have been machining G10 composite handle scales for my knives using this exact method for quite a few years. I have had ZERO issues with this style of clamping and it lets me produce handle scales where every single dimensional feature is done in one operation which is pretty amazing! I'm cutting the material to thickness and machining the underside features and clamping features in OP1 then I mount them to a pallet which is held onto the main fixture using Pitbull clamps in order to machine everything else in OP2. Works fantastically well! I don't have any features that are dimensionally critical on the backside, so I just use 2x 1/4-20 SHCS to hold them down and roughly position them on the pallet. Keep up the great videos Jay! -Aaron
I'm a seasoned machinist and didn't really learn anything new but I watched the whole video. The way you can simply explain more complex topics is excellent. I wish I could communicate this well. Jay, are you naturally this good of a teacher or did you have to work at it?
Love the whole range, when you go from shop made fixters and vice work to a custom pallet system it opens up so much more,if you think out side the box
Love the videos. Let's give the Rotovise some more love on this channel! I have the PPS and the Rotovise, and though they're both great products, the Rotovise is 100x more useful to *my* parts and part volumes. I think the PPS is really a winner with 3-axis work at volumes over 1000x per year, and almost nothing I make sees that volume at this time. But the Rotovise with the serrated jaws is transformative for reducing operations, still getting a solid number of parts in the machine at once, no custom fixturing expenses or time for each new setup, and it's also invaluable for prototyping and one-off work. If you do lower or medium volume work the Rotovise is a massive win, even if you don't need multi-axis -- just having more vises in the machine is great. Used in tandem with a Stop-loc ruler, you can't beat it for op1 mill work.
Just get that plane flying!!!! I will make CNC parts for you. I will design and build electronics for you. I just want to build a Dark Aero myself. Loving your approach to design and engineering.
I love watching these videos. I own a 1970 Bridgeport and even though I wouldn't be able to use all of this system. I offset my work with a 3D printer so it helps tremendously!! 👌 I hope to eventually grow my business enough to get a CNC and I will definitely give you a call to put in some orders. 😉
One tip for people still using the standard part-in-vise and having troubles with op2 mismatch or part damage from overclamping due to unskilled labor or operator error... use inexpensive torque wrenches and specify settings in your setup sheets.
Oh I got one Pink panther insulation that hasn't been sintered yet. Heat shields for gas turbine engines. We would literally hold it in our hand wherever you touched it if you blew Air at it but where your fingers were would fall out. The parts we made were big thin and complex.
Great video. Very interesting ideas! So are you just machining the bottom features to clamp the part in op20? Why not machine the complex corner rounding features in op10 and then clamp the parts with softjaws for op20? I think that would be easier then screwing the parts again and you can safe the excess operations. Also if you mount the op20 clamps on the same tombstone as the op10 parts you could safe the other pallet completely and take out 4 finished parts ever time the setup is run.
Give the video a second watch. We don't want to use a vise because of the problems I mentioned. First operation also handles 4 faces so the 5 axis machine is ideal and high-density workholding is perfect for the second op.
Would love to get into making more high density fixtures but most parts I am making (job shop) seem to either not have the quantity to offset the cost in the fixtures, or not lend themselves to a palletized design. excited for the day I get the right job to do so though!

Well spotted! I didn't notice that.
Great eye indeed!

Thank you. Like any skill, I have to practice my on-camera communication. I am definitely not a natural.
You do a great job
I am so happy to see Fixture Friday! I learn something each time and I’d love to see this type of thing every single Friday!! One can wish. :)
I really want to work there for the summer just once. I feel like I’d learn so much and have my mind blown even if I was just an operator
Nice fixturing setups. Me likey

Thanks Joe! You bring up a lot of great points we'll be sure to cover in future videos.
Great video! With those feeds/speeds you can really crank through some parts. We will need to upgrade machines soon. 😎
Tormach to a Haas perhaps. 🤔

Jay, well done. Great advice! Beautiful product.

Great video as always Jay
Glad you enjoyed
Very useful video, thanks! You are sharing a lot of 'proprietary' knowledge, much appreciated!
I mean if you run part like this then you get a multi pallet machine, worked with brother twin pallet myself love it, such a quick machine
Love your content Jay, keep it up!!!
Just had my own CNC today, although it’s a router, but I think similar method can be apply. Thanks for sharing 👍🏼👍🏼👍🏼
It's Soo lean, so perfect
Use a paint market on vise draw line to tighten vise to consistant torq
Love your mindset man, thanks for sharing!
I use this method to machine mold components. Best accuracy and accessibility!
Always a legend

I know an operator that can do quick change overs very fast, it's an ABB IRB4600 robot 😁😁
Luckily, robots don't get raises.
Great video. Very interesting ideas!

I made a video for guys just like you: th-cam.com/video/02V6X-9bZyI/w-d-xo.html
Is it fixture sunday now?
Sure, why not. You can always wait 5 days to watch if it makes you feel better :)
4:50 can’t you use in Programm probing to compensate for the shift?
Sure, you can probe each part, but probing makes for ridiculously long cycle times.
Ok now i understand. The threaded hole is part of the design and functuon of the valve, not designed just to hold it, right?
Correct. The threaded hole is for a cap to seal the cylinder. The two holes next to it are for fixturing only.
What’s the process to get rid of the threads after you don’t need them anymore?
The threads in this component are part of the design. We need them! :)
@6:28 Awesome video but I don't like how the operator just picks up the fixture and loads it in the machine without wiping the bottom of it.
how heavy are the pallets?
8x12x1½ - 13.75 lbs
8x16x1½ - 17.37 lbs
10x12x1½ - 17.25 lbs
10x16x1½ - 23.00 lbs
@@PiersonWorkholding you guys really need a metric version. But good product
@@mooreevair I know how to convert, but it's still only 2 countrys left these old measurements
@@kingkasma4660 I'm American and use metric and standard every day son
@@mooreevair sure thats the thing America is one of the two only countrys using more than metric.
Would have been nice to see it running 😞
Start using metric system instead. Inch is ridiculous and makes no sense.
