Spencer, what ever you get paid it is not enough! You are by far the most creative and clever wood worker I have seen on RUclips. I learn something from every one of your videos, thanks for posting!
Agreed!
In the past for long laminations I have staggered the joints on glue up to give me the length when length was greater than 8'. That way your final is only one joint. A little awkward but a stitch in time saves nine. Also measure true length of stock needed with string around the jig....
I’d be interested to know how you bid for a task like this? Looking forward to part 2, good stuff love this channel.
$125/hr?
Useful details, as always, especially making your own bendable plywood. My local supplier can provide bending plywood, available with the flexibility oriented in either axis of the sheet, so that would be my normal choice for this work. Your method avoids the cost and lead time to order it in. Other than the convenience of being able to make the bending stock from regular plywood, would you see any advantage of one material over the other in this application?
Being readily available is the main thing. The poplar plywood I was using also had a nice finished veneer on it.
Just like wiggle board goof concept.
Never thought of wrapping it great idea I will use that one!
For some strange reason, I never thought of using a planer to remove the 3rd layer of veneer; I usually just ran the plywood strips through my table saw to remove it. Funny how something so obvious can be so hard to think about. 👍
I'm making a mantle with a tight radius in the center that I wanted to wrap with quarter saw oak plywood, but it won't go. Watched this video and the resulting wet noodle plywood wrapped easily. Thanks for the tip.
I once got a great side job doing some Reno work for a lady. At the last minute she suddenly asked me to install a port hole window for her and had to be done right away.
I had no idea how to make a bent window jam, so I bought a piece of 3/4 PVC mounding and spent 6-1/2 hours straight trying to bend it with a small heat gun... lol.
By some absolute miracle it turned out ok, but holy hell did I work for that $.
Been down that path with the heat gun and PVC. On some pluses my initial mistakes were cheap to correct and took me 4 hours after that. I’d I wasn’t so “ODC” per my wife think I would have been done in 2. And I was just doing a small project for her.
This def great vid S years ago, we would do all kinds of tricks to make an oval like in the vid. 1 week and $$$ of lumber and some Seabee CAN DO spirit got it done. Spencer’s def much easier ( of course nothing is simple when doing it for govt on active duty. 😏
LMFAO "That wasn't suppose to happen" I think I say that 4 times a day LOL
Well do you mind if I stop by and use your Planer ? Santa Claus hasn't brought me one.
Sucks bc I have never used one but it won't matter. I'll go find me a couple of Beavers and let them work for me hehehe.
Damn I love your channel although I'm not very good at working with lumber.... Peace and love from Texas buddy.
One can buy bending Lauan that is made to be bent in a tight radius. 3/8" thick material has three plys. On both sides the plys are across the width and one ply in the middle is very thin which runs the length of the plywood.
Came here to say this. It's called bending board around here. You don't have to plane normal plywood.
@@markshelton735 what is your point?
Discovered this process years ago for curved wall base. Slice up the base cap to bend. Takes Two pieces. remove thickness of blade on one piece set blade width of blade kerf and rip full piece first then a rip from the piece you previously removed the thickness of blade. Alternate the rips.
I hope you have a SawStop. That rip cut brought back some bad memories. Just call me Lefty!
He just broke $300 worth of wood
Around here we buy this from a store and it’s called “wiggle wood”
By the way... the official name of that plastic wrap in my world is Roundy-round.
Never seen it done this was - superb. Only seen people doing cross cuts
Spencer sounded like the Donald at the end of that video, with that ughhh!!
Spenser:
To protect your workbech/layout table from glue, use a 36"-wide roll of butcher freezer paper, as on side of the paper is coated which makes for an easy clean-up of the excess glue with a damp cloth. If careful, you can get multiple reuses of the paper. Pulll tight and clamp each end. Also, make a 3/4" plywood hanger bracket for the end of the bench and use a 1"+ on the roll. Mount the bracket to the bench legs where the top of the roll is below the benchtop, so the "permanent" bracket and paper roll does not interfere with your horizontal work plane. Lastly, use a 38"-40" long section of an old bandsaw blade as a paper cutter. Use a washer on each end as a standoff when attaching the blade to the hanger bracket so that the paper slides between the bracket and the old bandsaw blade. Make sure to hammer and remove any tooth set in the blade before installing, so your paper cuts are straight and without any ragged edges.

Great vid as usual. I just happen by accident meant for it to happen! but found this out a few years ago using a planer sled on my 25" drum sander doing some very thin veneers for laminating. The sled kept getting sanded over and over again and when the job was finished I noticed the sled was limp, due to the ply laminations getting sanded off. I then played around with some thicker ply to figure out what worked the best at bending. 100 grit on the sander was best taking a 1/32" cut from the ply to get what I needed. No more kerfing after finding this out...
Strap clamps might come in handy on this project too.
I always enjoy your videos. Thank you!
my mind was blowed some time ago, but I did not know how to do this! thanks
You are amazing 🤩
I’m speechless
You should come to Jamaica for a Holiday ! Richard
As always, fantastic video! Will you do a video on how to trim an oval window? Will that ply edge be visible in the trim reveal?
Yes, but with paint grade it will be covered with a bead of caulk and paint.
I am extremely thankful that you make this additional effort so that novice yet motivated carpenters like myself can receive the BENEFIT of your expertise!!!
Thank you 🙏 I Love these videos
Glad to help
This never even crossed my mind. I've been conditioned to not run MDF and ply through the planers because the glue and cross-grain dull the blades. Good technique though. Thanks.
Matt, he ran plywood, not MDF, through his planer.
@@idontthinkso666 Thats why I said "ply"
Crafty work, very nicely done.
I came to watch you cut semi-ovals on the table saw.👍
You are so talented and make everything look so easy. Id be struggling with that for days if i could even get it right lol
Great video. Have you tried bendy plywood? It's used on curved stairs all the time, then veneered
That is a new concept to me. I’ve always kerf cut plywood to make the curves, but may try your method to see if it’s a better and stiffer alternative.
WE have been using using bendable plywood panels for cabinets and millwork for years. I can get 4x8 sheets that bend like your strips. Mind blown...not totally...BUT I will give you a big At-a-boy for thinking of planing off one ply to make it bend able. In a pinch I am going to try that. great videos....
First, that was a awesome trick!! Never would have guessed to plain the top ply off. Then to figure out to wrap it. Man I know those are not cheap. So labor extensive. Great video sir.
Great presentation--you'd be a good guy to work for.. You can eliminate snipe and too much excitement if you put a 'sled' of 3/4 ply underneath the piece you're planing.
Ok skimming one layer of the ply off to make it bendable is something I had seen before... But I never thought about taking another skimmed piece and gluing it back on after the bend to keep it from springing back and probably make it a lot stronger... AWESOME idea!
Had you thought about possibly using your joiner the take off a layer? Maybe Double side tape it to a flat 3/4” board.
🤯 My mind is officially blown! I’m not even joking. I’ve made flexible plywood for client protects many times by running the piece through the table saw at half the with of the board. That method requires hundreds of passes with the table saw and a lot of patience. You definitely should’ve patented this invention 😂
Just a side thought: after a really long and hard day at work, maybe while you’re cleaning up the location you’re working at, maybe while you’re driving home, or thinking about how you’re going to tackle the next few days of work with so much to cram into so little time, do you ever find yourself taken aback and completely humbled knowing you’re doing for a living, the same trade our Lord did over 2000 years ago? It’s extremely humbling and especially encouraging. It’s just a thought that comes to mind when I seem to most need it.
I truly enjoy your videos and admire your skill. I will admit that I learn much from you. God bless you brother.
"T and A"..registered, sir
Plane off an exterior ply. Clever. I wonder if aligning grain is how they make “bendy” ply (or whatever other name it’s called). By the way, around here the plastic wrap is called “flat twine” - at Ace Hardware. Seems like your cut and join method is an easy way to create a uniform lamination without a lot of measuring. Thanks for the video.
Why do I have a sudden desire for Pasta Alfredo?
Seriously, I’ve never had a need to know how to do this but now that I do I want to see oval windows everywhere!
Spence the plastic wrap is a fantastic idea, I make the same bench template but brace between the opposing offcuts, use ratchet straps to hold it all in position, you will get a perfect undistorted shape as the ratchet straps puts even pressure around the whole shape, I use bending ply but will give your method of removing the outer layer a go, looks a lot easier.
Great video i have a couple of ways of doing laminations like that you might find helpful. To type it out would take way to long. i might have to make video to show you this will give you some options not that i is better just different. You do great work!
With all your clamps do you have any band clamps? Possibly would have worked well to pull those last two joints together, but hey what you did got the job done, I really like my Pony band clamps, great job Spencer!
Dollar Store or the after Christmas sale wrapping paper rolls are good for laying down for glue ups. Cheap enough. Turn it upside down if you don't like the picture.
Great technique. Great explanations. Great video. Great job. Very clever.
Nice technique Spencer. Thanks for sharing your knowledge.
Another great video. I’ve been involved in wood working for many years as a hobby and your videos are great reference material. Thank you keep up the great videos.
You’re a baller love the channel, how’d you get started you have a huge shop and more importantly lots of skill for such a young carpenter
Thanks a lot 🙏
I used door skin with a lamination on my last curved jamb. This plywood is a better color though than luan door skin. Only 5/16 may show on the edge so you could do two layers of poplar ply for the visible part and luan door skin on the bulk for structural strength.
You are the maestro !!!!!!
Hot glue some extra blocks to keep it round take advantage of that extra flexibility
Excellent video as usual. It concerned me at first when you talked about planning off that veneer I thought of my steel knives on my planer going dull, but you ease my mind then when you referred to your spiral cutting knives, I assume carbide.
That plastic wrap is excellent tool in the shop along with masking tape, for glue ups .
Thanks for your videos that are very well done and helpful.
¿Y qué pasaría si desde el inicio, traslaparas tiras de madera consecutivamente en forma lineal, de tal forma que, lograras cubrir toda la circunferencia? Te ahorrarías hacer empalmes galleta. -----------------
And what would happen if, from the beginning, you overlapped strips of wood consecutively in a linear way, in such a way that you managed to cover the entire circumference? You would save yourself making biscuit joints.
Greetings from the Mexico's city.
that.... wasn't supposed to happen I was gonna use that piece ;-) thanks for the thorough test!!!
From all the other methods, yours is marvelous
Welcome back
Really great video, one of your best in a while. What I like best about this is bringing together multiple elements that I’ve seen before, but in a new unique manner. Efficient, cost effective, practical, and doable by the average finish carpenter. This should be one of your top 10 videos ever!
Nice job boss , scrap vinyl flooring works good as glue protection. The glue does sink into and stick to the tables .
Very cool trick!
Glad I found your channel. Appreciate you sharing your knowledge, means more to me then I can put into words.
Glad to help

Spencer for the paper for the shop go to where the print the news paper and get the small rolls to short for new run works good luck thank for all your tips.
I agree, Michael. I value Mr. Lewis’s generosity in sharing his knowledge.
Excellent job,I did not know that about 1/4 plywood!
Hi
Rather than butt joining as you did, would it not have been easier and to router away half the thickness off each piece for say 8 inches and do a lap (scarf) joint.
Kind regards
Ewen Kerstens in New Zealand
Very interesting
Every day is a school day. Here is me thinking you where going to run mitre cuts the length of the ply.
Strap clamp??
Sorry.... I meant to say that perhaps the joint would be stronger as well as easier. One of the reasons that it could be easier is because you would not have to get the length deemad right because you can simply slide the 2 pieces on your frame and then clamp.
Mind blown!
Mind blown !
Mind freaking blown. This is a game changer
You try using door skin and and ripping it down? It’s pretty flexible
I appreciate your content so much! So many great ideas!
Outstanding
Hola. Mi.nonbre.es.adan
Pero.megusta.tus.bideos.
You blew my mind..have you tried on say 1/2 ply?
There are plywood’s that are called bendy board with multiple thicknesses and horizontal and vertical choices,I use it a lot when doing architectural pieces,thanks for all your videos.👍📐🇨🇦
I’ve used the bendy board in the past, it’s great when the inside of the bend is the show face. But when the show face is the outside, the wood grain opens up a little and creates an unattractive surface.
@@idontthinkso666 Hey Pat it is used for forming,then covered with a laminate or vaneer.
@@troyqueen9503 well, I agree, covering it with a veneer makes that a non-issue.
You look like me when the task takes a day longer than you thought.
The off cuts might make good wobble boards for toddlers.
Hi, Spencer. What kind of playwood did you use for it. I tried with one sanded 1/4 from The Home Depot and it did not work.
Poplar from a local lumber yard.
I think if you ever seen how a drum shell is made you would take a different approach.
You want a template of an odd shaped window? I saw a man hang a piece of thick construction paper over a window and use a soft roller to mark the crease from the window onto the paper. You end up with a perfect replica of the window into the paper. Much easier than cardboard?
This is a new one for me. Watching it come out of the planer was crazy.
Nice trick. What about a ratchet strap around the jamb while it’s in the jig?
Don't most lumberyards have wiggleboard plywood?
No! I never knew about this 'Black Magic' ply removal! I'm not sure I could trust that template cut by someone else before starting this project, I'm sure he double-checked it lol...
I definitely double checked it. lol
How would the Bessey strap clamps work on your jig?
"That wasn't supposed to happen, I was gonna use that piece..." LOL! I hate when that happens.
Planing one side is brilliant! I was expecting bendable plywood, but that stuff is expensive. I'll be using this trick a lot. Thanks!
About the plywood blocks, it seems making plywood ovals spaced apart would make for a smoother bend. Just throwing the ideal out there. I haven't actually tried it.... yet.
That would definitely make for a smoother bend. On a perfect form like that you don't even need to clamp, you can use lashing straps.
Product here in Ireland which i presume is available over the seas with you as well. Flexiply or superform ply. Same thing available in different thicknesses. But I presume because you wanted the poplar face that's why you used your method. Which is perfect as well
We have it here in the states, I’m in the middle and we use a lot of it, we refer to it as bendi board, thin layer of veneer in center with 5mm/3/16” bendi-ply on out side faces, but your correct after we create desired form we then veneer with desired specie or laminate, there’s also what we call kerf core, I’m going with the fact he wanted poplar surface.
Learned something today. Thanks!
Great job can’t wait to see the next process.
WOW! Thanks for the info. Great work as usual.
Looks good. I'll have to try a few of those tricks.
Thanks so much for your videos. I was being taught recently how to do arches for some tight radius arched windows. We came up with a different strategy, but had I seen this beforehand I would have looked like I was up for a raise. You The Man.
Glad to help
Your skill set never ceases to amaze me 👌🏼👍🏼
What hearing protection are you using? I’m looking for something else to try and those look convenient, great videos thank you for taking the time to make them.
Retractable bluetooth headset.
You can use an electric plane to remove the back ply.
No. I did not know that trick. Thank you
