Most important part of using glue is surface preparation. Good mechanical join with roughened clean wood with open pores is always going to be stronger than the wood with almost any glue.
@5:05 "I may edit some of this shi" lol
Brandon Yea that made me laugh!
yeah, that was golden!
Brandon.....Yeah I CAUGHT that!..LOL! Have A Super Week!.....Gus
This video proves you can get kick back while working at a table saw.
Love the Slo Mo Laugh at the end!
Sixstringsandapick.... Me too..but my Puppy didn’t like it a bit!..LOL! Have A Super Week!.....Gus
It's a blessing that you show these experiments John :) Another barrier of thought extinguished :D
I called it and I loved it -- I knew we were going to get a slo-mo of the piece of wooding hitting you in the face. Thanks for videos! I always love to watch!
Great stuff! I get way too many comments on my ridiculous glue-ups with people assuming they'll fail. I was planning on making a testing video similar to, this showing that the glue is stronger, but I'm just going to send them to this video instead ;)
Always great videos.
Thanks, John. First time I've had a full blown vid to answer one of my questions! lol. Again, thank you for taking time out of your day to provide us with answers.
Thanks John for helping us understand more about the glues we use to glue things up. I now know that the glue is the main stay of the wood when doing a glue up. The tempreture in the shop does make a difference but not in the holding strength of the glue once it is set up. Great video. Thanks again.
Thanks for the edi . . .
Thank you for the video. Helped me understand better.
Sick coughing in the bed - John (and progress ISS mission 69) saved my Day.
Thank you!
Something I’ve preached right here. Glue is stronger than wood. Thanks for the detailed show and tell John, awesome video as always
Wow! I wasn't subscribed to this channel? Well, I have solved that issue now.
You are one of a handful of the woodworkers out there that I look up to, to learn from.
Thank you John, and keep up your great content coming in.
This is a great video, thanks. Perhaps a video showing what makes people think wood glue is weak. So if you broke a joint that wasn't clamped tight enough or was over tightened. Perhaps one with not enough glue.
Great video John. My 'shop' has heat issues, as in I don't really have heat. I have a forced air propane heater that I run intermittently to at least keep my hands warm. This is great because I always end up carrying clampfuls of stuff into my house, or gluing up in the kitchen, which is always a hit with the family! Thanks!!
Good video, and I agree with your reasoning. When I glue up a panel and then cut it to length, I always try and break the offcuts to make sure I got a good glue up. They always break in the wood, and not the glue, except for one time when I hadn't jointed the edges adequately, because, as you say, the wood glue *may* not fill in gaps.
I had to remove deck sheeting that had been put down wrong just one day after it had been laid down and let me tell you it was a huge chore. The construction adhesive would NOT let go! 3/4 T&G smashed all to hell and the rest of the day chiseling the rest off the joists. A work day straight from hell. Thanks for the video.
Great video as always. Practically approached, detailed and very very useful information. Thanks for sharing.
I think you should post the last bit (with the focus on the glue/panel test) on your other channels. This deserves a wider distribution.
That's incredible, I had no idea that wood glue was so strong. Thank for the info!
Cool, I can only work outside (on a covered terrace) so it’s very useful to me, thanks John
I have a end table that is glue only. No mortise and tenon joints and it's holding up fine. I can bend the legs and it still won't break at the joints. I'm not going to try to break it as I would like to continue to use it. Modern glue is amazing.
That was a perfect demo, John.
Wow!!! Excellent demonstration video. Thanks!!
Nice video John, as always.
Interesting, I just completed a science experiment with my son for his grade 7 class testing the relative strengths of different wood glues, the only way I could get a wood joint to fail was by gluing end grain to end grain. There was a difference between the different brands / types but all were stronger than the wood if used as most of us do and not end grain to end grain.
Bob...
That difference may have been due to other factors, like the amount used and the openness of the end grain in each piece.
Nice vid and test as always. Only one point, if you want to test with this configuration without "point loads", which I presume you mean pure bending without shearing. In that case, you can still use the traditional setup sitting the board at its two sides but apply pressure on two points (or two lines, parallel to the sides, to be precise) rather than one (at the midspan between the supports).
I read your blog for a bit more detail, I agree with it all as far as it goes, thanks for adding it. I would like to mention the use of white glue( basic PVA) for furniture repairs because the glue will give way before the chair leg ! and the urea formaldehyde glues for waterproof work ( Cascamite etc) they really work for laminating boat ribs and deck beams ( clean it up today !!) Thank you for your article.
That was great fun to watch! Thanks, also, I liked the low temp glue test.
Finaly, now I know. Thank You.
John, since we are all such high minded moral beings, you should collect all of the clips of unexpected things happening into an out cuts reel!
Another great demo John. I definitely need to get the plans and make those clamps
Thanks for sharing your ideas on glue strength !!! 👍👍👍👍
+ John
Well now we know. This is something i have wondered about glue joint .I purchased the plans for the clamps you glued that board up with....I think. Had some issue there. Waiting to see if it shows up on my cc account. Thanks for making them available.
On with the show.......
Really enjoy these videos. Thanks john
Thanks for sharing John, another good informative video.
Thanks for the explanation and excellent demonstration!
Nice test, love the slow-mo!
That was actually a good information. It was also nice to see both styles of clamps in action in the same video. And the new ones definitely appear to be a lot easier to operate. Now we just need a strength test of the new clamps.
Build one and test how strong it is.
I use a "winter" variant of the PVC glue in the winter, it's "ok" down to -10C. Can be stored down to -40C (I get regular -20 to -30 in Winter)
Funny clip at the end with the wood attacking you!
Great Video John! Thanks for doing what you do Brother! You are a huge inspiration! Very soon I’ll be Starting a RUclips WoodWorking /Maker Channel! I’ve been following you for a very long time and I appreciate the contribution you make to the Community! My only wish, is that I can contribute a FRACTION of what you have accomplished! I’ll shout at ya when I launch! Have A Super Week!.....Gus
I always wondered why carpenters glue was yellow, now I know. Thank you sir!
Boragon77 I
thanks for the replay, I missed that the first time.
Very informative, thank you. As a beginner I'd love it if you could talk a bit about the dos and don'ts of glued joinery. How do butt joints do under load, how does the glue react with end grain vs long grain, how weak (or strong) such a joint might be, etc.
Answers to some of that in the blog entry, the link is in the description.
That hit at 11:20 got me LOL!
was wondering about the glue sticking to the clamps now I know thanks
I Build It Scrap Bin: What is the brand of the construction adhesive that you use?
Gluely noted!
Great vid. But I just wonder what exactly would happen with vertically placed glued board and clamps grabbed for any of two different board parts.
I would appreciate if you could repeat it with left over scraps.
Thanks for this video. It confirms what I have read. My next question is, when is it not enough glue? In other words does the glue ever fail as opposed to the wood? Do you have to completely cover the surface to be glued in order to achieve maximum strength?
This video also does a fantastic job of showing how much your clamp design has improved over the years. Those old clamps are still impressive, but they look unwieldy and inconvenient as all get out after seeing your new design in action.
White PVA is also a little bit more susceptible to water. Yellow glue is not immune to water but it resists better, which makes it more adequate to make furniture, doors, etc.
John, I started out doubting glue but quickly learned otherwise. I wonder if the only real advantage to screws and dowels, biscuits or dominoes would be the resistance that they would provide in regards to cyclic forces over time. That would make for an interesting test.
Cool
Is the test board beetle kill pine? I ran into several boards almost identical to yours and haven't seen it before. Forgive my ignorance, and don't mean to side-track.
Great video .... I sure miss those Hulk vids 😊
Love this stuff. is that glue you're using on line (can you buy it on line?). anyway... I really like watching you videos. you've taught me quite a bit of knowledge, thank you. keep It going. Awesome.
Like your tool board behind you. Did you ever do a video on it?
Also, noticed your older clamps had holes instead of grooves. That looks as if it would be a stronger clamp.
I have mine heated to 18 degrees celsius. To me that is a nice temperature to work in.
Just as I expected! And as I gain experience (And by no means do I call myself a pro) I'm starting to notice that the label "Premium wood glue" doesn't mean shit, just has to be PVA with something on it to make it more water-resistant and it's more than enough for me...
Yellow glue is stroger than white? I have white which is D2 class and yellow which is D4 class. Its only waterproof class i think.
so I have an experiment to try. end grain to end grain glue-ups and end to side grain glue ups... even side to side. I want to know if you can strengthen the joint by soaking the end grain a bit with really wet/dilute wood glue to make it penetrate deeper, and then gluing up with the dry glue in the joint to complete the bond. would it act like, say, what peter brown did with bread? or would it be a pointless endeavor?
Pointless. If you want a stronger bond for end grain joints, use a stronger glue, like epoxy.
Which shop we can buy the wood glue
Any idea how much clamping force you’re getting from the clamps?
How about excessive heat, here in Australia my workshop can hit 50c in summer, mostly around 35c .will the faster drying produce a weaker joint? Maybe flyover for a week to do some tests.😉
This is super stuff for guys like me who wonder about using glue in their 5-8C shop for about half of the year. Did you ever use, or can you get, Ever Build 'Stixall'? It is very popular here because it works under water and in rain so that's just the job for Ireland. I have never had a fail with it. I might do a video showing it used to glue concrete slab together under my stove.
I've not seen that here, but it does look like good stuff. According to the published specs, it not as strong as the polyurethane construction adhesive I use and talked about here.
Ah, that's interesting. I hadn't done a comparison. Now I have to compare all the adhesives I can get here... LOL
i guess you didnt want some freebies from titebond! i guess they need to make some for the canadian cold !
I've not done any tests, but in my previous shop I regularly had yellow glue dry chalky due to sub zero temps, I still didn't get a single joint fail. I try to bring stuff in the house to dry now because it's faster, but I think the glue manufacturers are being way over cautious on their recommended temps.
They recommend for best results or ultimate strength, even if that ultimate strength exceeds the amount actually needed.
Very little effort (with a big lever). LOL. From the camera distance, the board looked quite attractive. I like spalting. I would have used it to make a small table top. But for the greater good of the community it had to be sacrificed :D Thanks John. P.S. get a wood heater. Shame to waste all that wood
As always, great vid and explanation! Just to take a tad further, although wood glue is very strong for wood it isn’t so good if the surface already has a finish on it.
About the only time this ever comes into play is if your reclaiming wood from old furniture or something. Always get rid of the finish in the areas your going to glue.
Have you ever observed this with wood glue?
Or use a glue that will bond with finished wood, like epoxy or polyurethane construction adhesive. Easier to use a different glue that to try to remove a finish.
I really got to try that PCA that you talk about and use all the time. Excellent point!
Was just trying to point out a weakness with wood glue that I found the hard way....and got a better solution for the next time. Thx!
So you put wax on your clamps. Does that mean some can transfer to your work, and cause blemishes on the finished part?
HEADSHOT!
Hi John. I use Tightbond 3 because it says it's waterproof. I've never tested this waterproof claim. Am I wasting my $ on hype?
I do need a waterproof glue for outside projects.
Suggestions?
"You'll shoot your eye out!" Thanks for the slow mo.
I googled Celsius vs Fahrenheit and found that 5*C is equal to 41*F. Does this cold affect the wood after completion of a product when it is introduced to a room that is 72*F? I am a starting out woodworker (even tho I am 67 yrs old) and have many questions. I like your videos as your are direct to the point when showing us how to do...... Thanks, Don USN ret.
Temperature has no effect on wood (other than fire), only humidity does.
Interesting experiment. SCIENCE!
The polyethylene chopping boards don't stick to epoxy resin. You should make some epoxy resistant clamps using chopped up chopping boards. If you intend on using epoxy, idno..
i expected the cast iron to break first.
And you said you dont make enough scraps to burn!
Right inna' face! At regular playback I thot it just got ur shoulder a bit xD
Ty for the glue info btw
Yellow glue will take 3-5 freezes and that's it, I use Gorilla, super glue or epoxy.
Interesting test John, one question, did you have the glue stored in the 5 degree celsius shop to start with?
It wouldn't matter. As soon as it hits the 5 degree wood, it would cool down to that and stay there until it dries.
Hey Jon! Did you delete the video about getting banned? My bf and I we’re excited to watch it lol now I can’t seem to find it
I unlisted it for a day to try to stop morons from making rude comments on it. It's public again.
Some people will never learn. We love your videos, thanks for making them!
Glue it back together again
Hey John, is this glue available in the US? Maybe a link as where to get this?
Hotrod Hog it’s just wood glue. All if it says wood glue or pva on the container then it’s essentially the same thing.
Great explanation and demo John. Does this also say something about the volume of glue we tend to put on joints? Maybe a bit of overkill?
Always better to put more glue in a joint than not enough. Excess will just squeeze out, but not enough results in a weak joint.
The Goldilocks amount of glue!
That said, if there is heaps of squeeze out then this is a good indication you are just wasting glue. So much easier to get an idea from too much / too little and use just the right amount (as Timothy Hall said: The Goldilocks amount!). Maybe another point is the Goldilocks amount of pressure on your clamps as too much pressure starves the joint of glue and too little pressure can leave a gap which as JH pointed out may not work. Good video, Cheers, David.
Can Focus Master host one of the episodes? #givethepoorguyachance
I think with this kind of joint there is no need for dowells or biscuits since it is that strong ???
when gluing edge grain or face grain there's no strength benefit to using biscuits or probably dowels either. joints involving end grain is where dowels really help (not sure about biscuits). one benefit of biscuits is they minimize unwanted movement during glue up - helping alignment.
Can you do the same test with an end grain joint?
No reason to. As I said in the blog entry I wrote to go along with this, regular wood glue doesn't perform well with end grain joints.
I Build It Scrap Bin Somehow I knew the answer but I looked for your reply and I was right, thanks to all your videos I’ve watched
Thanks John
End grain is a different story.
Hi John, I have the same problem as you "no heat in my shop" I know you use building adhesive and I probably will not be able to buy it in the UK, but could you tell me the make of the building adhesive so I can try and get the same stuff.
It's available over there - it's PL Premium
You can probably get som Casco or Bostic construction adhesives aswell. Super-Set is the name of the casco flavour. Titebond aliphatic glue is usually available in luthiers shops.
I can't speak for any other types of construction adhesive - they will almost certainly be much weaker and therefore not at all suitable as a replacement for the brand I mentioned.
John. Gripfill from screwfix is very good. Not bad price either. Martin
My glue all seems to say use at above 10c - always have a laugh at that since I'm in Scotland, it's not abnormal for it to be below that in the middle of summer.
I try to do all of my gluing up in the heated indoors for this reason though although i find that between 5-10c it just takes a bit longer to dry - stuff left outside overnight glues up fine. Below 5c and I won't attempt it though, just doesn't ever set up in my experience.
Recently i did a test with two pieces of a bit dark colored wood by overlapping one over the other with titebond 2 as glue and i clamped it hard and left it over night.The next day i removed the clamps and tried to break the two pieces apart and it just came off easily??????????????
… very interesting test, i guess. But did you realize where the brakes appear? - The clamps themselves seem to apply a hug force on the wood. Meaning: the brake is concentrated very close to the clamps. Thereafter it would be even more interesting to see if you would take other - may be slightly bigger - clamps and and place them exactly where the glue-joints are.
My favorite part of the video was when that small piece of wood jumped off the table to hit you in the face :D
You are lucky it was a small bit of wood and not that chisel that hit you. What do you keep in your drawers and store space if every bench is covered in tools and scraps. Once you get in the habit of putting things away, its nice to have clear work space.
Agree regarding brand names, but there is a huge difference in type I and type III glue regarding water resistance. Check out Ron Caverly's series on this (worth a follow btw - the guy is a turner's turner and he really makes great vids) ruclips.net/video/AEGDXg0S-H8/видео.html
In short - type 1 dissolves quickly in water, type III really does stand up to water in a much more substantial way, although as he said, "I wouldn't build I boat out of it."
Not sure why I felt compelled to write this, as obviously you (John) knows the difference, but you should check out ol' Ron's channel.
For my own giggles... there are multiple things wrong in this photo: randomer.net/stuff/glue-all.jpg
I never really understood why people make clamps... there are so many excellent clamps readily available.
You make things because you can.
