Super cool. Great build! 👍🏻👍🏻
Thank you!
Traditionally it’s called a “Butt Bowl” “Asstray” or “Derrière Carrier” but I’ve never heard “Seat Dish,” weirdo.
Butt Bowl sounds a little toilet-y, but I am loving Asstray and Derrière Carrier. Might have to switch it up.
😂
Never considered what to call that part, but after watching this video, I actually really like calling it a seatdish 😝🤣🙈
"Butt hugger"?
I always thought it was called a butt cup.
Haha, that sounds very accurate.
Shaun, you continue to set yourself apart stylistically. I love how you're evolving into showcasing time laspsed builds but also interacting with your audience through your explorations. Highly enjoyable, cheers!
Really, really appreciate that! As I make more videos, I always just try to make them in a way that I would find enjoyable, so it is awesome that others like them, as well. Thanks for your support!
I was thinking butt platter. Butt what ever you call it. It is definitely not dishwasher compatible.
Haha, like that one! I'll have to add a sticker on the bottom that says "not dishwasher safe".
Why is CNC work called machine work, and other work called hand-made when table saws, band saws, jig saws, various sanders, etc are used?? Takes experience and some skill to use chisels, draw knives and other non-powered tools . It also takes experience and skills to learn to design and program a CNC. The argument “hand-made vs machine-made” is just bullshit and usually by someone without the knowledge, skills, and ability to learn how to use a CNC.
If you decrease your step over enough with the ball nose endmill, you will eliminate the vast majority of your sanding. I believe I use a 1/10th step over on a 1/4 inch ball nose bit. You can also increase the speed a lot on the final pass if you are using the same diameter ball nose to compensate for the tiny step over. Obviously the 1/10th is relative to the size of the bit, so a larger ball nose needs a much smaller step over setting.
Thanks! That is actually what I did when the first test cut had all that texture. Worked really well, and yeah I am always afraid to ramp up the speed, but you are definitely right.
90 percent overlap toolpath you can get the best results on 3d model route. And yes a rough pass with a endmill at 50 percent overlap and then a ballnose bit with 90 percent overlap.👍
I dig it.
You may want to consider getting a router with a brushless motor. Typical routers are not designed to run for such extended periods of time and that carve looked like it took a while. Brushless motors produce much less heat and should hold up better in extended-use applications.
Thanks! And yeah, I figure I'll just run this little router as long as I can, then go from there.
Awesome Shaun!!!1 Keep up the great work
? You oriented the seat grain so that it runs side-to-side instead of front-to-back. That means that the seat connects to the leg frames as end-grain to side grain, in the dados. Since you don't appear to have used any form of joinery at those two connections the only thing holding your chair together is a few square inches of end grain glued to side grain. Where face grain on the top and bottom of the seat contacts the legs the situation is reversed: face grain on the seat is glued to end grain of the legs.
Your chair design is unacceptably weak and cannot survive heavy loads or ordinary daily abuse. To rescue the design you'll need to introduce some type of strong joinery...perhaps a sliding dovetail might work. But simply gluing end grain to face grain *at the most critical load bearing point* isn't good practice.
This exact chair has seen daily use for the past 2+ years, and is still as solid as the day I built it. I think you are underestimating the strength of a well-fitting joint.
Ass-pan (Websters Dictionary)
Just getting to this one -- really cool walk through. Makes me want to get to my next X-carve project....
Thanks, man! Yeah, I am having fun seeing what I can do with the x-carve.
my wife the ergonomist, says it's a seat pan. But(t) whatever..
Seat pan! Pretty sure that is what I have been wanting to say the whole time. And if I am going to trust anyone, it is an ergonomist.
I would love to see the steps in fusion360 to set up tool paths and model.
I am still just a beginner with Fusion, but maybe I can put together a video that goes a little more in-depth with that stuff in the future. Thanks!
I’m way late but I believe the technical term is ass groove.
Ah yes, the ass groove. I think you are right.
First, good job. B. It is henceforth called a seat dish.
A. I appreciate it. Second, thanks for confirming. and 3. Glad you caught this one.
Great edit of that chair man. I was thinking parabolic profile cuts rounded off at the butt end but cylinder crossed with sphere - man that is cutting some shapes! +1 for gags as usual. +2 for rugby t-shirt 😁Cheers Shaun.
Thanks Rob! Yeah, that was the only way I could get it to make sense in my head, so I ran with it, and luckily it worked out!
pity about the music
Is it a Walnut Tree?
Just a stupid amateur question... couldn't you turn the seat piece around and have the CNC machine take out a decent chunk on the rim too, where it now is extra thick as nothing was carved out? That would reduce the thickness of the Dado used to fix it to the frame (say at least down to an inch?) and might look better overall, just not sure if it's stable enough...
I like your use of the Xcarve. I don’t think it should be viewed as the end all tool for making furniture but rather a special purpose tool. I want one just for making templates!
Totally agree! They can be really nicely integrated into a traditional woodworking/furniture shop without it being the only machine getting used. Template making is a perfect use for one!
It was a little hard to see the difference, honestly. The shirts would be really helpful when buying lumber. #ShaunJoke That's a nice looking chair, and I like how you try to get the organic and machine to work well together.
Thanks, Bruce! Yeah, it is really subtle and probably something I obsess over more than I should. But I just can't get over wanting it perfect.
🤔 If you can envision the design, and model it, then cnc carve it.... How "really different" is the output if you were just to "make it by hand"? It's still made by you... Just facilitated by tech 😉
Yep, I agree. Two different schools of thought, but both equally legitimate when it comes to the creative process.
Shaun, just discovered your channel. Good stuff. I like your style and your philosophy re: CNC and its place in woodworking. But, Dude, please get some lighting on that face when you're talking to the camera. Just my two cents. Keep up the great work and take care.
Thanks Torin, really appreciate it! Yeah, the lighting in my shop isn't great, which I have been wanting to fix for awhile. Just a matter of time and money at this point. And I went to film school for two years, so I definitely understand where you are coming from.
Love this chair, and I really like the thicker seat. What was the total cut time?
Thanks! Yeah, the thicker seat is not only sturdier, but I think it just looks better with the overall design, as well. I think total cutting time was maybe an hour and a half to two hours? I'm sure once I do a few more I can get it dialed in and maybe reduce that time by a bit.
Shaun Boyd how does that compare to carving by hand? If you don't mind me asking.
Love the idea, might just try it myself.
Honestly, I can probably carve it by hand quicker, it usually takes me about 30 minutes to do the rough carving, then maybe another 15 or so to get it sanded smooth. The only differences with the CNC is the precision, and the fact that I can do other things while it is carving.
Shaun Boyd multitasking with a machine is so much better.
Who's that hatless dude in the glasses you've got doing work for you?
He's kind of a dweeb, but he works hard.
CNC router also shaves beards, apparently. :)
Instant headache when you cut into that seat haha! Awesome stuff Shaun. It takes a lot of skill to fix a mistake and make the final product look as if nothing happened. 👍🏻
Haha, yeah it was a little nerve-wracking. I'm glad I was able to get it done. Thanks for watching, man!
As always great videos. Iike your cool demeanor and approach to how you make your videos and explain your process.
Curious how big is your shop is?
How do you may your beard disappear than reappear? What type of sorcery are you using?
Thank you, really appreciate it! The main part of my shop is around 30' x 15', then there is the little office at the front that is maybe 10' x 15'. Works well for what I do, but I am starting to feel the squeeze. The beard thing is a mystery to me, too. It has a mind of it's own!
Hello my friend. Very good idea's. And your plans. I am from greece.if you want to help me with your cnc where i can find. Thanks
Thank you! Not totally sure what you are asking, but my plans are available on my website. www.shaunboydmadethis.com/plans
That's a beautiful repair!!! I love the terminology, AND the shirt! Next maybe a "Seat Dish thesaurus page" shirt???
Haha, I like that. Maybe all the different terms for a seat dish on it. Thanks for watching!
K so I am going to be making the cnc leap here in the next few weeks to help speed up some of my production pieces, I am interested in the the x carve system so the question I have is what size did you go with, what all accessories did you get and also what would of differently, like the size or the bit order or the dust collector?
Awesome! I went with the 1000x1000mm version just so I am able to cut larger furniture templates with it, and I have already maxed it out quite a few times. As for accessories, I kept it pretty basic and got the side board to hold the controller box, and the dust collection kit, which has been a great addition to the machine. I also got the v-bit set and Easel Pro which is awesome if you plan to carve text or a lot of signs, etc. Hopefully that helps!
Great looking chair. Have you considered cnc-ing the underside of the seat to follow the contours of the seat dish, making it of uniform thickness?
Thanks! I hadn't considered that. Could be a cool look, I might have to mess around with that idea at some point.
Looks awesome!! CNC to me is another tool to use for certain tasks, no I don’t have one so yes it’s my opinion. I love the final seat tray lol and what a excellent job on replacing the seat that had to feel weird like sick to your stomach weird cutting out the original seat tray. Awesome video. Take care
Thanks Thom! Yeah, I agree CNC is just another tool to have in the bag. And yes, replacing the old seat was a little nerve-wracking, but I am glad I was able to get it done successfully.
Is the joint holding the seat strong enough? Because you are gluing end grain. And if the legs bow out under the weight then the seat will fall out of the grooves (dados?).
Yeah, I don't think there is much risk of those joints failing. You would have to sit down pretty violently to have it break, but I will definitely report back if something like that happens. Thanks for watching!
Hey man!
Another great video! I know you were apprehensive about jumping into the CNC world but your making it look possible. Keep it up and I’m going to have to pull the trigger sooner than I had hoped.
Question: Any insight on seat grain direction for a cantilevered chair??? I noticed yours is running cheek to cheek (for lack of a better phrase). I initially was concerned that the chair could snap under the weight at the point farthest from the fulcrum and was going to orient the grain Butt to knee pit???
Any rational behind going with one over the other?
Honestly, grain direction on the seat is really just an aesthetic thing for me. With the thinner seat that was on there before, I was a little worried that it would fail, but even that would have taken a lot. So unless you are a violent sitter, I would just go with whatever looks best to you.
You said "first" and then "b)" instead of "second". I loved it. Somehow it feels like you hid this easter egg in the video just for me.
Haha, I was wondering if anyone would catch that. Nicely done!
Great job, how long did the xcarve take to do it? What was your feed rate and depth per cut?
Thanks! I would say it was probably around an hour or so of actual cutting, maybe a bit more. I think I did a total of 3 toolpaths, but don't remember the feed rates. Depth of cut was probably 1/8" or so.
Really interesting As always you did fine. By the way I like you better without the beard.
Thanks, Marc! I'm sure the beard will be back at some point.
It'd be great if the plans for purchase of the chair included the g code for the seat dish! I'd love that!
Yeah, I have just been trying to get it dialed in before including it. Hopefully once I have it just right, I will add it to the download.
A good approach to using CNC in conjunction with handmade furniture.
Thank you!
Bun Basin or Cheek Chalice perhaps? Regardless, great video and demonstration of the new CNC.
Two very good options, definitely adding those to the list. Thanks for watching!
i call it an asspan
Haha, that certainly makes sense!
You're dad joke skills are excellent. How many kids do you have? ;)
Haha, thanks man! I don't have any kids, that's why I use all my jokes in my youtube videos.
@@shaunboydmadethis so you're just a natural... Nice
Nice save
Thank you!
Do you sell these? How much do you ask for a chair like this?
Yep, I sell just about everything I make on TH-cam. I sell these chairs for around $450/each.
Rad save! I hope you make it to Workbench Con this year. Would love to thank for sharing in real life!
Thanks! Yeah, I'm going to see if I can swing it this time, would be great to meet ya!
Oh shit, it's bearded Shaun, where did he come from.
A blast from the past.
Which extras did you get with your cnc? I reviewed and it seems there is a whole heap of choices....
Yeah, there are quite a few things you can add to the machine. I kept mine pretty basic and got the side board to hold the controller box, and the dust collection kit, which has been a great addition to the machine. I also got the v-bit set and Easel Pro which is awesome if you plan to carve text or a lot of signs, etc. I'm sure some of the other accessories like the z-probe and homing switches are nice to have, but I haven't added those yet.
Hey thank you for taking the time for all of your replies Shaun, you are a man of worth.....
What software is used to complete the 3D modeling of furniture?
I use Fusion 360 for 3D modeling.
Thank you.
I love your laid back videos my dude
Thanks Nathaniel! I try to keep it chill.
The correct term is actually "butt tub" or "cheek cradle"
Oh man, butt tub! Haha, that might be a new favorite.
Shaun , great to watch your CNC machine . Always love your work . Thank you
Thanks Mahendra! Really appreciate it!

Nice video, very entertaining. : ) Beautiful chair.
Thank you! Really appreciate it!
Awesome video man!!
Thank you!
I really like your music selection. Very relaxing.
Really appreciate it! I enjoy choosing the music for my videos.
Grow it back! oh god! Aghhhhh!!!!
Haha, I'm sure it will be back at some point. It is babyface Shaun for a bit though.
Definitely getting one of those tshirts soon!
Awesome. Really appreciate it, Scott!
Nice your idea shaun. good job.
Thank you! Really appreciate it!
Yes, we noticed the lack of the BEARD :)
Haha, I am babyface Shaun for a little while.
It's actually called a "Butt Pan".
Ah yes, that sounds familiar!
Butt dish... its called butt dish
Haha, certainly makes sense!
grow the beard Shaun
Haha, it will be back again at some point, I'm sure.
Nice seat dish. Now on to the real questions, are you actually an Angels fan?
Haha, I was a fan back when the logo on my hat was their main logo. I don't follow them too closely these days, but I try to stay at least a little bit informed. Thanks for watching!
@@shaunboydmadethis but we have the GOAT, you gotta watch now. I preferred that logo as well though.
I know! I actually went to a game earlier this year and got to watch him play. I'll really start paying attention if they make the playoffs haha.
@@shaunboydmadethis Yeah I've only made it out once this year as well... But I watch on the mlb app a lot.
updated!
Tush nook?
Oh, I like that. Sounds comfy.
Excellent
Thank you!
Sempre muito bom assistir teus videos.
Obrigado!
