Building a WORKBENCH That Does Something No Other Workbench Can
Вставка
- Опубліковано 2 лис 2021
- This workbench has a trick up its sleeve! I built a workbench that does something no other workbench can. This DIY workbench has a UHMWPE top that allows me to pour epoxy directly on the surface. The epoxy peels up cleanly once it cures. This workbench is not just functional as an epoxy pour workbench. It functions as a traditional workbench featuring 4 finger jointed drawers that pull out from either side. I designed this workbench in sketchup and cut all the parts on my AVID cnc. You could build a similar version of this workbench for yourself by simplifying the base design. I just wanted mine to look awesome!

Do yourself a favor and don't borrow money!
Hi, the machine at 1:50 cutting machine , if you please, what's it called? what did it cost? where did you get it? how steep the learning curve? thanks :)
"No sag" Your top needs at least one run going the length of the table to be a torsion box otherwise its essentially just 2 sheets of plywood. I'd totally drop that much for a bench top but I don't think I'd cut the grooves into it, I think that might limit it in the future. Very cool design though, I like it.
I think it’s technically a torsion cubby hole now haha
Yeah, I'd have a hard time justifying those grooves in a $615 board. I think I'd try to find ANY other way to get the functionality that the grooves will theoretically give.
@@SuperDavidEF just look up how badly that stuff gets abused in combat robotics 😂
The first half of the ua-cam.com/users/postUgkx3ICSK6nSknaL_45CU2NmFSoXjarGMDiJ book is everything about wood: types, tools, finishes, setting up shop etc. The second half is all about doing projects for inside and outside of the home. The color pictures are helpful. After reading a dozen of these types of books, this is probably the best overall (layout, color photos, plans). Only detraction is that many of the projects use a table saw/router/planer, which are usually expensive and take up space, so the plans are less friendly to newcomers and the budget conscious. But I know I can use a drill, circular saw or a jigsaw to make the projects.
I learned nothing about how to build a good workbench, but I'm so glad now that I know about M1 finance
Your torsion box is only halfway towards a torsion box, so it makes sense that it sags. You need verticals going both directions, not just one, if you want no sag
I agree.
Without several ribs running the length there is no torsion prevention to it. He can lift one corner and the whole table will twist. I agree as well.
Yea, it's not a torsion box. Its two pieces of plywood with dividers between them.
Very true.
This is just a poorly designed fancy table. CNC does not mean well designed. How does a channel like this get 433K subs? I guess people love a train wreck.
I watched to the end but I will not be dictated too. I will not write no sag 'cause I'm a rebel. 😁
I read a few of the comments and I have to agree with the others. You don't have a torsion box. Any unevenness in your floor can result in twisting of the table top. I like the concept of the slide through drawers but I think I'd approach it a little differently. I'd put together a true torsion box and then add the drawer section underneath. I'd also inset the legs a bit (I run into enough things already).
Also, even though it's UHMWPE, it's still relatively soft and can get scratched and dinged up over time. I used to be in the composites business and I had a flat mold that had a gelcoated fiberglass top. I built a plywood cover for it that I could take off when I needed to use the mold surface and cover it to protect the surface and use it as a workbench when the mold wasn't needed. The cover was just a sheet of 1/2" plywood with a 1x2 trim board around it so the ply wouldn't slide off. Just a thought to help protect that $$$ investment.
I was thinking the very same thing.
I'm most impressed that you did this in sketch up with a track pad
I would totally use a UHMW bench. Might have to make one now 😄
The strength of a torsion box (aka stress skin) comes from what is essentially an I-beam made from the ribs, top skin, and bottom skin. Without going into the structural math, you need ribs running the length of the unit that are glued to the skins if you want added strength in that direction.
The aesthetics of those legs is awesome!
No sag
No sag; agreed. I know it's more difficult to see some of these flaws while designing/building but as a certified back-seat carpenter I saw it while you were assembling that the center section had no triangulation or truss properties. Rather than add a center leg I would have added full-length trusses under the second sheet, and glued them to the legs on each end.
“No sag”. Nice project. I really enjoy seeing others build projects that they see “needs improvement”, and then problem solve to make it work for them. It’s really inspiring to see! Great build Johnny!
Looks so damn pretty I would be afraid of messing it up.
Seriously it looks that nice. First time my drill bit went through my wood and hit that table top I would
be physically sick.
This turned out so sick! I love how unique the design is!
Thanks 🙏
Good thing you added that center support. It's easy to store your plywood now.
"No Sag" 🙂 I was just doing some maths and trying to see if it would be worth buying the fancy top to use for appoxy projects and got a HUGE surprises. Say you were doing a load or large tables or some other project that required a large area of appoxy. $600÷$40 (expensive fancy top ÷ sheet of melamine) = 15 sheets!!! You only need to mess up 15 sheets of melamine before it would have been cheaper to buy the fancy material!! If I used resin on a regular basis I know which I'd choose. Good advice, thanks 😊
PPG paints sells a paint called "Breakthrough" that is a waterbased paint designed to act like oil based paints. It's finish is extremely tough and depending on how many coats you apply, can act like a stain by allowing the woods grain to show through if you prefer.
Instead of a 3rd leg make a 4" I beam out of 3/4 ply and run it along the underside.Cutting the parts out with you CNC and with glue the beam would be super strong. Love the bench! I would def spend the cash for a top like that.
I've watched your videos and have to say you are an amazing designer and wood worker. the work bench you created was just beautiful. I'm just starting out right now and getting familiar with sketch up. I'm thinking you're using SketchUp Pro. I know it takes a lot to do these videos with all the editing, but please keep up your awesome work. looking forward to more of your awesome designs and work
Great looking work bench!
Personally I like the natural look of the pine with white top. I’d hit the plywood with a clear poly just to give it some protection.
I have used uhmw for all sorts of things. This stuff is truly amazing. I keep finding more uses. It is worth every penny.
Excellent design and I love the industrial esthetic. You could fix the sag problem easily by using sides for the box also made of plywood (something similar to Ron Paulk's design). The strength in the box comes from the sides.
This is UA-cam woodworking at its best and I must confess I am envious - of your large workshop and CNC machine. I was designing workbenches out of plywood along similar lines back in 1990 (a project in my book Electric Woodwork) years before UA-cam. My only contribution to the sagging issue is you could double up on the thickness of the plywood for the topwhich will also give you a stout surface to use a mallet or hammer on the top (assuming these techniques are used in the USA). Filling in the rear of the drawer openings or adding triangulation there would help. I love the scultural form and the use of this plywood (It is called Brazilian pine) I have been using variants of this for my furniture designs since 1979 is precisely why I am building a CNc machine. You beat me to it! This is a refreshing non myth busting non clickbait video as anyone can see from the thumbnail what is promised in the video. There are some great drawer constructionds there and novel tool extensions used. Nice.
I'd love to add HDPE or UHMW to all my assembly and resin pouring workbenches but here in Australia, I'd be looking at somewhere in the region of $5000 for that as compared to maybe $200 for 5 or 6 sheets of melamine. I'm just about to swap out my melamine for new sheets for the first time in 2 years as they're a bit battered and bruised now but still, that's a HUGE price differential. The resin I use pops straight off melamine without a single issue so the only bits I ever throw away are the edge pieces and as a rule, I don't often build forms for my tables anyway, I tape off the river, clamp down to the bench and pour and then cut to size when I'm done. Works like a charm. I'd be worried that I'd do more damage to the UHMW trying to get the slabs up off it. And then you've wasted a phenomenal amount of money. But, if money is no object then I guess, yeah, it's nice.
Nice Design. Very much like how RC Aircraft are made using Foam Core.
work bench looks great. Based on your video, it looks like it would be useful even if not using epoxy on several projects. wish I could afford one like it in my craft workshop.
3:14 Regardless if the tabs are tight or not, I can visibly see in the video there is a bow and that the top/bottom is not flat and true. This top should have been clamped with cauls. As for the warping the other way at 5:45 "Torsion" box designs require stringers. This is where they get their strength and rigidity from.
Cool project! Love the table and your shop is awesome! I enjoyed the video too!
Awesome Work as always I need that top you put on there. Loved the easy to peel surface on it.
Nice looking build. A few comments/ suggestions for your structure. Some of those pinned/
Glued joints could use some screws after the fact, and screws to attach the legs to the table instead of glued in case modifications or repairs are ever needed. I wouldn’t call that a true torsion box with no longitudinal members, sag ought to have been expected in that set up. If the top was a torsions box and didn’t sag I’d still suggest a stringer run between the bottom of those two outer legs and the center one would not be required. It’s nice to make fancy cool looking things in CAD, and CNC skills, you clearly have that down, now I’d just suggest brushing up on some basics of structures. If the designed were refined a little more it almost looks like something you could package up and sell to consumers, or at least your plans/models.
no sag - love the design and use of the CNC for the box joints (no dog bones for the female rectangles???). A bit much $$ for me on the top, but understand the usefulness if pouring epoxy regularly. As others have said, a vertical member in the bottom or center of the top would likely cure your sag. Love the video - keep them coming.
That is one awesome workbench!! That top is a great idea if you do a lot of epoxy pours. Love the idea of not throwing money away to the dump.
I vote that you clear the plywood.
No sag. Interesting stuff. I like the epoxy pump too
Fantastic work, Jonny! 😃
Yeah, it can be expensive, but it's totally worth it!
About the finish, apply something that can seal the wood... Just in case you ever have some accident with epoxy. You know?
Anyway, stay safe there with your family! 🖖😊
Thanks 🙏
That epoxy after you peeled it off looked like one of the "holes in the ground" from Roger Rabbit!
Such a simple way to locate and secure the material to the bed of your cnc. Love it! I have to ask thou... How often do you hit a nail? And how many nails till you start to see a difference in the cutting action and need to change the bit?
No sag! Love the table, it very unique!
never would blink an eye on that cost worked with the stuff before only part I did have a problem after a lot of use started to get out of shape we made roof trusses on them 5 year use they did their part well
I’m a talker, too, boss! 😂👌🏻
Wow! That's beautiful. Great stuff!
Great project. Any chance you would make a kit of it for those of us who don't have a CNC?
Bless your heart for using the track pad on a drafting program
The bench design was outstanding. Yes, I would spend the money for that top on the bench. Because I'm old and don't know computers is the reason I don't invest in one of those CNC machines
Another guy that knows how to use a computer program, and put simple puzzles together. I almost thought I found a woodworking channel. Damn.
I like the design, looks realy modern!
I really really dig the look of this. Awesome build
I'm going to agree with others who've said that your design doesn't quite make a torsion box because you don't have any beams running lengthwise. That third leg in the middle will find every little un-level spot in your floor.
Great looking bench. I personally would have turned the curved legs around so they curved in, that way your not banging your knees on them when you walk around. Although the top has a pretty good overhang so it might be alright.
Jonny you said at the beginning of the video you was going for the industrial look with this workbench just with that inmind I would use spray paint and colour all the wood in a silver/gunmetal colour!!! As always buddy 💯% 👍 🇬🇧.
What will you do if you want a table top bigger than the grooves are you going to fill in the middle grove with plywood two ? Or just have a raised rib in the center of a 4 foot wide top? No sag
No Sag! 1000% worth every cent for the work surface it's going to make money in the long term, no brainer if it's affordable in the short. Another great video, thanks for the upload.
The best workbench ever.Love the look.👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👍❤️
Sweet workbench! No Sag now! Ready to see the epoxy projects on there!
Very creative and cool design. Really like that Clean look. Keep up the great craftsmanship and hard work my friend. Keep making. God bless.
My first thought after watching you build this entire bench using the CNC is "Eat your heart out, IKEA."
That said, I'm dropping a comment and thumbs up because this is unique, original and a great idea come to life. Beautiful.
Thanks 🙏
No sag! Pretty dope design! Saves you money in the long run and is super functional.
That is awesome! I love the work bench! Beautifully done ✔
Cutting grooves into the top is probably a bit of overkill. Manor Wood just hot glues lengths of HDPE on his pour surfaces
Great use of the CNC. Black or industrial gray paint would love very good and would contrast with the white top IMO.
Very cool workbench. Awesome table top.
very cool! The first thing that came to mind about the plastic top is that there are a lot of small plastic recyclers making sheet goods that are affiliated with the Precious Plastics movement around the world, may have been able to save a few hundred bucks buying a recycled sheet of PE or HDPE. very cool idea for what you are doing., got a new subscriber out of it.
🙏🙏
Looks cool for a saggy no sag table. i would clear coat it to show off the plywood and design.
Apart from the old knee's (I feel ya pain) what an awesome build. Absolutely love the aesthetics with the industrial look. Amazing work as always brother
no sag! I absolutely would spend the $$ to get the bench top if I continued to use those materials like you do. Well worth it in the long term. Nice work.
II am a leather crafter I need to resurface my cutting table top. I only Is either a scalpel or round knife to cut leather. Is the UHMWPE top a good cut resistant top?
Man, this is AMAZING!!!!!!!
Color suggestion: Silver hand beaten paint. Would continue the industrial look.
My hat off to you. Excellent work.
12 months ago I spent $1200 on 10mm thick aluminium sheet for my table tops. If I was to buy the same aluminium today, it would cost over $2500. I do want to get removable UHMW to cover the tops when I am doing pours. But I don't want it to get damaged if I was to use it as a work bench aswell.
very cool!!!! Now I want to make a mini version of it
You for sure nailed you’re first and second goal, Mr Builds.
🙌🙌
Smart!! Fantastic build
No Sag! Hella cool workbench. That top will save you money in the long run. Well done.
First of all bad ass secondly no SAG. Honestly brother blown away by this. Such a cool design right in the feels
Thanks brother 🙏
Awesome build I really like the look of the legs they would make nice speaker stands.
How do you like your Husky Cabinets. Building a new home and looking for a good Black cabinet can have Blue accents too... I have seen a lot of Tubers have them.
Paint the bench in Mosou black!
Lacking longitudinal rails, your torsion box isn’t a torsion box. Nice save with the center leg, though.
I really like the curvilinear industrial look legs.
And the UHMW top is genius!
Thank you.
I really like the UHMW sheets. Just finished replacing my router fence plywood sections with it. It is pricy though.
No Sag love the greatest table I have ever seen . I want one now so so very much Thank You very much
Very unique design. Great job!
The bench does look cool. Couple suggestions. Instead of rhe center support touching the ground you could have made/added something like an I-beam down the center for support. 2nd, I'm sure you will notice over time your drawers will be hard to pull. I'd recommend you take a little off the height of each. Then add a small piece 1/8" thick, running the length of each drawer on the bottom edge. Then you can run wax along these. The wax will make them slide very smoothly and easily. Be careful you dont pull them out the first time. Also, depending on usage you'll need to reapply wax every few months. You can use a simple house hold candle for the wax. Cool work bench though.
Great workbench. Would you happen to have the ASPIRE files that were used to cut the pieces? Would love to build it.
I noticed you didn’t allow for the radius of the cutter in your mortises compared to the square tenons. Was there enough give between the two parts when you hammered them in?
No sag, good job. Cheers from Kansas
Sincerly a awsome work.
No sag. Besides the fact that it is functional and pretty good looking, the best part of this entire video is the comments which follow. Everybody knows better than you and seem to forget that this is your video and your table. Hugely entertaining and definitely makes my Friday.
Thanks 🙏
Why not just put some splines under the bottom of the “torsion box”? It would’ve added the strength your looking for. I put torsion box in quotes because torsion boxes by definition have boards that run in square grids so that it prevents racking in all directions.
How will you deal with grooves when you pour a big slab? Won't the epoxy get in the grooves? Tape the grooves maybe?
Beautiful design!
Two vertical supports lengthwise could have been attached to the leg assemblies and your work bench would still be able to roll around. What you have done relies on your concrete slab to be dead flat for the top to remain flat. But it is a cool looking design, almost furniture like.
I see you had to make several passes of the CNC to cut the UHMW, and you stated that it is very durable,, but how easy is it to put cut marks in it accidentally?? Also,, can you plastic weld the UHMW like you can HDPE?
yes, I would spend the money. that's an awesome idea, a great design and a well worth it project. Just one question, how much to buy it from you and how much to make it. Like I wanna know material costs and what you would make off of it if you did sell it. ok, done rambling.
Once you make a large pour, won’t the grooves become part of the pour? Do you have blanks to fill those grooves in those cases?
You might want a slight draft angle (2 or 3 degrees) on your slots, or if you do a big epoxy project that has a groove through the middle of your "mold box", if epoxy filled it, it would be a really thick piece and would likely be hard to get out of the groove, even if it doesn't stick at all.
The grooves under a pour will get filled with plywood strips and covered with tuck tape.
@@JonnyBuilds That's a better plan
There'll be no sag in that puppy. Amazing bench, and if I was doing lots of epoxy work, sure $600+ would be a savings in the long run. Nicely done !!
Thanks 🙏
Nice bench 👍👍
Wondering if you would consider creating kits for this workbench (for those of us without access to a CNC machine).
Awesome workbench, do you have the cnc plans to carve it?
Great job 👍
can you put a link in here for where you sourced that UHMWPE sheet?
Nice Bench. Where did you obtain the sheet of UHMWPE
How did you make the square holes for the tabs?
would sintered stone behave the same way? Im thinking of getting a sheet for my future work top for about 100 bucks.
