Home made double bar clamp, dual action bar clamp or scissor action bar clamp

I bought 4 of these clamps today. I think it will come in very handy. It looks very similar to what you did. Thank you for the detailed information.

[@DownUnderWoodWorks]

No worries mate. Enjoy your new clamps

@@DownUnderWoodWorks thank you. The new handcuffs will come in handy for me. 'll see. greetings.

[@jonwilson7555]

I'm catching on your work and I must say I like these clamps and your more recent upgrades.

[@DownUnderWoodWorks]

Hey thanks very much Jon, glad you like them.

[@UBO58]

Great design and construction! Bookmarked for use in the future. Thanks a lot for sharing!

[@DownUnderWoodWorks]

No problem Uwe, my pleasure.

[@kayray7338]

I made some diy bar clamps recently but these look way better. I'll have to try these but wooden ones. Great work.

[@DownUnderWoodWorks]

Thanks Kay Ray, good luck with it mate.

[@benyork3895]

That's such a good idea, I reckon I'll be making some of them! Thanks for posting mate

[@DownUnderWoodWorks]

+Ben York Thanks for the feedback Ben, good luck with it.

[@NicoSmets]

I observed these clamps in the build of your douglas fir table top. They look amazing

[@DownUnderWoodWorks]

Thanks Nico

[@LimitedShed]

Great job, I was looking to buy a set of these off of Amazon, but after watching you and how you made yours, i think i will just make some.......Thanks

[@DownUnderWoodWorks]

Thanks mate. its always good to try and make your own stuff. at worst if they don't work out you haven't lost much but have learnt a great deal.

[@eln74]

Wow those alum bars have great lenght that I'm thinking that the other can be used at the same time, just like you are using to clamp and glue a few boards, well, in the other end with an extra set of metal bars and screws another board can be cooking at the same time, I like it a lot. Tnx for sharing it with the world. Cheers mate!!! 😀

[@eln74]

And you gain yourself a new suscriber, thats a double thanks!! 👌🏻

[@DownUnderWoodWorks]

Yes, a double thank you to you for the sub. Cheers mate.

[@DownUnderWoodWorks]

A great and interesting idea Emmanuel. Thanks for the feedback, glad you liked the video. Cheers mate.

[@ianvicedomini2648]

I definitely like those mate. You can clamp a decent size in them for gluing up in terms of a surface etc. They would come in handy if you're building a chest of drawers to planks together or something like that. Great video mate 👍🏽 👌 👏

[@DownUnderWoodWorks]

Thanks mate

[@julian15516]

Ingenious my friend. It looks simple but ingenious

[@DownUnderWoodWorks]

Thank you very much!

[@mikecox3659]

Watching your vids ... I'm going to be busy! Thanks and great job

[@DownUnderWoodWorks]

Thanks Mike, inspiring others to get out in the garage and have a go and have fun is something i'm always happy about. Happy making/woodworking.

[@OneManBandWoodworks]

This is awesome, I need to make some of these to save myself hours of dominoing

[@DownUnderWoodWorks]

Yeah, they're a great idea mate.

[@stubee3924]

Could make interchangeable push blocks of various thicknesses for various stock thicknesses or glue proof spacer shims to place across stock. Great material selection and design to add accessories to.

[@DownUnderWoodWorks]

+Stu Bee Thanks very much Stu, and very true about the different size clamp blocks. Cheers.

[@garymccoy2888]

Thanks. Added the video to my playlist for future reference.

[@DownUnderWoodWorks]

Great Gary. Thanks very much mate.

[@grantoyamaha]

Great video , good to see an Australian on KZbin good onya mate . I'll have a crack at these.

[@DownUnderWoodWorks]

Thanks mate, its always good to hear from fellow Aussies supporting the channel.

[@neliorodrigues2249]

Ficou um espetáculo seu projeto sargentos dupla ação, grande utilidade foi uma ótima apresentação e muito boa à demonstração valeu obrigadao

[@DownUnderWoodWorks]

Meu prazer, que bom que gostou

[@telfree1]

that's a cool clamp do both purposes of locking and levels, i believe there are some enhancement can be made by doing snag/slid hole for easy adjustments instead of been restricted for the thickness of the pushing wood.

[@DownUnderWoodWorks]

Thanks mate.

[@Barnagh1]

Design and concept, as you say, really excellent. I can weld so I’d do a few little details differently, but I like the overall idea a lot.

[@DownUnderWoodWorks]

I agree John, its always good to start with a base design or idea and make it your own.

[@vladaks2396]

cool. the most simple thing is the most genial one

[@DownUnderWoodWorks]

Thanks very much Vlad.

[@michaeldillon4070]

quite a unique concept - well done mate.

[@DownUnderWoodWorks]

Thanks very much Michael.

[@Tim_Pollock]

Love the design mate, thanks so much for sharing!

[@DownUnderWoodWorks]

Thank you Tim, I need to make more of these.

[@pikifrino]

Congratulations! Excellent job. Thank u.

[@DownUnderWoodWorks]

Thank you Stelios.

[@junkmail4613]

9:56 How about a socket mounted in a reversible variable speed drill? Finish off the tightening with a ratchet if you wish.

[@DownUnderWoodWorks]

Yep, you could definitely do that.

[@tinycuisine6544]

Such a good idea, thank you. Ignore the down votes... I think they are Google generated to keep us improving and posting more videos ;)

[@DownUnderWoodWorks]

Thank you very much. Its all good, i don't take any notice of thumbs down.

Very cool shop project. Thanks

[@DownUnderWoodWorks]

Thank you.

[@dominicgeorge4246]

I will give it a try..it is pretty good

[@DownUnderWoodWorks]

+Dominic George Hey thanks very much Dominic. sorry about the late reply, only just saw your comment now.

[@rustyrichardson1242]

That was awesome. Will be making some. Think I will add strength by using the square metal pipes. But thanks a lot for the video

[@DownUnderWoodWorks]

No worries Rusty, sounds good mate.

[@bench_doxie]

I happened across this while looking for a way to make clamps for a large panel glue-up I am doing. You have a very clever idea. Thanks for posting it. Only 'gotcha' I can foresee is the wooden blocks cracking eventually. Be curious if you made any improvements. Subscribed. And no idea what @Dave Hutton is going on about. No such thing as a "patented copy rite" [sic]. It's "patented" or it's "copyrighted". Either way, at least here in the US, you can make your own *personal* copy of something. You will only run into problems if you try to duplicate and sell it. Not sure how it works in Australia. I imagine it's similar. :)

[@DownUnderWoodWorks]

Firstly, welcome and thanks for the sub. Your comment about the clamps is spot on because thats exactly what happened. I am going to remake that part out of steel, one day. And your right about the copy accusation, there wasn't any deliberate copying. I'm pretty sure its the same here, only a problem if you try and sell them.

[@966uht]

[@DownUnderWoodWorks]

+966uht Thanks for the comment, glad you liked it.

[@miguelasafcastellanos8702]

Great video tutorial!

[@DownUnderWoodWorks]

Thank you Miguel.

[@rafaljanicki9750]

What a great idea, thanks so much. Can You tell me what kind of hardwood are You using for the pressure pads? It seems very hard.

[@DownUnderWoodWorks]

Yes it is Rafal. Here in Australia we call it Merbau. Its most common use is for timber decking here is a link to some info www.woodsolutions.com.au/Wood-Species/merbau.

[@rafaljanicki9750]

Ok. Thanks for that. I know this species but here, in Poland, it`s very expensive, exotic wood ;). It`s sometimes used as decking as well. Most popular decking wood here is larch. I just watched some more of Your films - I like those - not many "off the mill" ideas. If I may, please try to balance the audio in the vids. ATM the commentary is quiet while the tool noises are very loud. Makes evening watching a bit difficult ;). Keep up good work, thanks.

[@DownUnderWoodWorks]

Thanks for the feedback Rafal. You're right about the sound. This was one of my earlier videos. I'm very conscious of noise levels now when editing my videos so hopefully you will notice its better in the newer ones. Have a great day.

[@kevinsmith1976]

Brilliant idea and affordable. Hail metric system ;)

[@DownUnderWoodWorks]

Ha, too right Dario. Thanks mate.

[@h.nelsonthibault1488]

Thanks for the video. Great, just what I was looking for. It took me awhile to realize you were saying "aluminum". What was the re-cycled extruded aluminum used for? It looks perfect for the job. I'd like to find one/some here in the USA. It looks like it might have been a sliding door frame?? Thanks for your help.

[@DownUnderWoodWorks]

The aluminium was the frame of an outdoor screened in enclosure at the back of my house. It basically screened in the area under an awning to make like an outdoor room. The space was 9M x 4M so I have A LOT of this stuff.

[@h.nelsonthibault1488]

So is there a brand for the frame? Also if you were gluing a panel 2M X 1M, I'm thinking you should have 4 of these clamps across the width. Do you agree?

[@DownUnderWoodWorks]

Sorry no brand name mate. It was already there when we bought the house. For a panel that big I would have at least 4 clamps. I intend to make more when I get time.

[@The1kapable]

great job enjoy from France!!

[@DownUnderWoodWorks]

Thanks very much from Sydney Australia.

[@ravivirmani8725]

[@DownUnderWoodWorks]

Thanks very much Ruger Steve.

[@rugersteve]

Your welcome, I will be making a few of these. Love building tables. Perfect tool for the job.

[@MrSmokinMirrors]

So I love the concept. But can this be done for thinner panels? This set up is limited by the thickness of the lateral clamps. Your work piece can be no thinner than that.

[@DownUnderWoodWorks]

Yes thats exactly right Jason. I made these clamps because they suit what i do. I don't envisage gluing up panels that thin but if i do i would use a different method. Thanks mate.

[@greenhornadventure]

One could add filler strips to the top and bottom to increase the thickness. Strips of plywood with a layer of packing tape should allow thinner panel glueups.

[@thesage1096]

@@greenhornadventure excellent idea mate. and such a simple solution. elegant

[@jellyg.8961]

These are really good. Question, how high can be the boards when using these clamps? Is there a way to use them with thicker boards or they are limited to one size? Thanks a lot for these.

[@DownUnderWoodWorks]

No, the clamps will work with boards almost as thick as the clamp will open

[@peacebeuntoyou8934]

I guess you'd just cut a longer set of aluminium strips for the end brackets.

[@UriValdez]

Great tutorial man

Thanks very much Uriel.

Another great video. Quick q though, there was a claw hammer laying by you in the video, was that made in Rockford Illinois? I have a set of those, old, and really like them. I know its a strange q but i dont see them around much.

[@DownUnderWoodWorks]

Good question David. The hammer (as far as I know) is an Estwing and I have had it for many years. Its my favourite. I have no idea where it was made and I can't even remember where I got it from. ill have to take a close look to see if it has any markings.

[@DownUnderWoodWorks]

Hi David, just had a close look at the hammer and its an Estwing made in Rockford Illinois. It had the numbers 24 and 07 and the letter H but I couldn't make out anymore.

[@TheWoodYogi]

Superb idea :) Really well made :) ॐ

[@DownUnderWoodWorks]

Thank you very much.

[@sumosprojects]

Love it mate, do you use them regularly ? Aluminium I reckon is best for this as the extrusion reinforces it & time would perhaps flex, dunno but impressed by your concept 👍👍👍👍👍👍

[@sumosprojects]

Time won’t flex but timber might lol

[@DownUnderWoodWorks]

Mate I do use them a lot but the timber thread blocks broke. I'm going to replace them with metal ones., probably just made from threaded couplings. I also want to make a parallel clamp using just one length of aluminium. Still developing that idea. Cheers mate.

[@bartduggan9388]

In reply to Dave Hutton's comments. I'm sure he will correct me if I'm wrong. But I would have thought copyright infringement only applied if a profit is made in any way. From what I gather DUWW is merely educating other people, and is not selling the video, OR the clamps. There are many other videos showing similar clamping ideas, so I don't see a problem. I know from experience that a copy right is not worth much because only a small detail needs to be changed and your copyright is shot to hell..

[@DownUnderWoodWorks]

Cheers Bart and totally agree.

[@davehutton4244]

Hi, came across this segment quite by accident. I want to bring to your attention that this is in direct violation of patented copy rite. THis clamp that you claim to have designed by inference, was in fact invented by DnJ innovations and patented back in 2008.. The compressx clamp. The product that you are showing people how to build bears direct resemblance and working action as the compressx. I would suggest that you remove this video from u tube and replace it with a written apology to The compressx people before they start legal action against you for patent infringement. I suggest that you are aware of this as they demonstrated the product at many Australian wood working shows as your wording for the clamp is the same as their web site developed back in 2008.

[@DownUnderWoodWorks]

Thanks for the comment Dave but I don't appreciate the accusations you are making against me. I have never heard of DnJ or the compressx clamp. Your insinuation that I stole a design is incorrect and I suggest that you withdraw your comments. If this DnJ or the compressx people really do have a problem with my video they can contact me themselves, and while they're at it they can contact the many other KZbinrs that have made similar or same clamps. Cheers mate.

[@paulpardee]

Patents and copyrights are two different things. You can't have a patented copyright. In most countries, copyrights (which protect works of art) are granted by default, meaning they are protected without any formal action by the creator. Mechanisms or processes can't be copyrighted. They can only be patented. The CompressX Clamp doesn't have a patent number listed on their site and I wasn't able to find one via a cursory search. Without a patent, an invention has no protection against being copied.

[@thesage1096]

oh ffs, ur just pissed that you werent the only one with such an idea. the only issue here is the stupidity of the patent office for granting a patent to such a simple mechanism. werent you embarrassed to run to the patent office with such a basic fabrication ( i wont even call this an invention).

[@JamesTatePa]

On the compressx website it states that Dave Hutton is the inventor and that he has a world wide patent copyright, although I am fairly certain there is no such thing as a patent copyright. I did a patent search and could not find the patent. I did find that he has compressx as a registered trademark. It would appear that Dave is trying to protect his invention but didn't know how and should have opted for legal advice. However, if you should decide to call your clamp "CompressX" you would be in trouble.4

[@JGumaJ]

You should probably get in touch with Woodpeckers, because they released the ClampZilla last year and it has the same design. Let us know how that works out for you... LOL

[@fixedit8689]

Too much effort, just use two clamps on either end

[@DownUnderWoodWorks]

That only ensures the ends of two boards next to each other are aligned, not all the boards at once.

[@s70cas7ic0]

The only modification i would do is to make the brackets from larger steel plate and work them in an angled shape so to have the lateral clearance to use a wider pressure pad

[@DownUnderWoodWorks]

Thanks very much for that tip Luca

[@positiveaspect5730]

I had the same thought ( to increase the area of pressure more towards the middle) but I don't understand how you would do it? do you have an example of what you describe, please?
