I made some minor upgrades to the double bar clamps that I made a few months ago.

Hello my friend. I started using very similar handcuffs. And now I'm building myself a big desk. These clamps are very useful and practical. And solid. Thank you for showing the details. Stay healthy and happy. Big greetings. Kind regards. Mehmet
Sorry for late response. I made two of these using 50mm square aluminium and used your updated system. I couldn’t believe how simple and useful this is. I have used these quite a few times and noticed that if you tighten it too much, the bolt skews upwards and now, I don’t do that but just enough to see glue just comes out. Thanks for this great idea
That is an awesome idea you have and you have done a great job of making the jig. I may try to make a set of these clamps using uni-strut instead of the extruded parts. Keep up the good work. Dan
I loved the wood tap idea! When I make one, I think I will see how to make the back moving scissors easier to remove and move, maybe with the screws just going into the holes 1 cm rather than all the way across to the opposite side scissor.
Great work. It might be possible to make the 1/2 in rod wood block more robust by inletting the two nuts into hexagonal holes. Counterbore 3/4 inch dia. holes for each nut and then chisel the six flats making a socket for each nut.
Thanks for the feedback George. The wooden blocks did fail. What i'll do is replace them with a 12mm/1/2" metal coupling and weld the two nuts to the side of that.
Hey, mate, nice job on those improvements. Is there some way to adjust the relative amount of clamping (horizontal) force vs cauling (vertical) force? I would think that you could either add more/closer holes or perhaps as spacers _under_ the pieces being glued so that they effectively reduce the vertical clamp width? What do you reckon?
Mount some low feet to the lower bar that are then mounted to a strip or square of ply so you can moderately clamp the lower bar to your assembly surface. No need to wrestle wet glue boards and 2 bars. Work pieces elevated better air flow to cure glue. Wood block steady rest on threaded rod and clamp to surface and put a table-saw hand wheel on the end of the rod. Cut-offs of the square tubing. Flip the scissors pivots inward and you have a low clearance spreader bar. Install levelling up tool of large cube and flat assemblies. Shims and blocks and slip-on forms for bent laminate work. I'm sure there is more people can think of built from basic parts and basic adaptation similar parts. People should throw up their ideas here. It's all about accessorizing these days, don't you know?
I have 3 very similar clamps- purchased from Shopsmith here in the US. They are of a "caul" type- a gentle radius - They are quite expensive. Are you still satisfied with your design as they certainly appear to be as effective and much less expensive. And- nice video work!
Hey John, the clamps still get used and I'm still very happy with them. I actually used them today to edge glue two slabs for my next project video (coming soon). Cheers mate.
Yeah, I'm lucky to have quite a few lengths of that stuff spare at home. As I mentioned in the original build video you should be able to make them using 2x4s but I haven't tried that myself. Cheers mate.
Its always better to have more than you need Jason rather than being caught short. when you think about making table tops, most would easily be close to the width of these clamps. Cheers mate.
what kind of wood did U use for the blocks? I have a lot of wood that was given me that was said came from Australia, it looks a lot the same very hard and dense!!
Unfortunately I'm not very good at identifying timber species. The timber I used for the original blocks was Merbau. Its very common here for outdoor decking. The wood I used for the new blocks was some very old reclaimed wood that could be Grey Ironbark but I'm not sure.
I enjoy the content you have provided but I am thinking it could be time to look into getting yourself a mic because it is often hard to hear you. Thanks for the vid's
Thanks for the comments and the feedback Jamie, sorry about the volume issues you had. My videos were never about my videography skills (because I don't really have any) but just about what I was doing in my workshop and hopefully inspiring others but you're right, I know one day I will have to upgrade. Thanks again mate.

Good to hear that Mehmet, thanks very much mate
@@DownUnderWoodWorks You're welcome. See you. big greetings.

No worries mate, its always great to hear back from people that have made things from the channel.
That is an awesome idea you have and you have done a great job of making the jig.
I may try to make a set of these clamps using uni-strut instead of the extruded parts.
Keep up the good work.
Dan
Hey Dan, thanks very much. The uni-strut is a great idea. Good luck with it.

Interesting idea, i hope it works out
Great project. Good to use what you have on hand.
Thanks. I have so much more of that aluminium square tube that I'll be making some DIY parallel clamps with it soon. Stay tuned.
thanks for sharing and thanks for good remarks.
Thank you very much for your comment. Apologies for the late reply but I'm trying to clear my "Comments I haven't responded to" list.

i've never really thought about it Phil. It would be a matter of just experimenting. Thanks Mate.

Thanks mate, some good tips there.

Great, I reckon you could market those clamps - although buying the extrusion new would probably make them a bit exxy I suppose.

Great improvement to the original. But are you really going to be making panels THAT wide? Those are very very wide.

You could glue up 2 or more panels at the same time if they were similar thickness

Scrap wood from the scrap wood tree, very rare.

muito bom
Thanks mate.
HI I BARELY EAR YOU
Yeah sorry about that Luis. What can i say, its one of my earlier videos. Sound is much better now.
