- DIY parallel clamps build.
These are based on plans available from bellevuewoodsho...
I highly recommend visiting his channel and site.
I used 3/4" galvanized electrical conduit pipe, superstrut threaded rod, washers and nuts to match, and some used lumber.

Not only that I enjoyed, but I was also impressed with your project outcome. Brilliant work!
Dude, that rotation to find center tip is life changing! I love how many variants there are to this clamp design. I even have my own, but I think this way is much faster. Great video!
Great video. Good that you showed the "uncensored" hole drilling part so we can all learn and also see that we all do mistakes were we learn from them. Good narration. Good editing. I loved it.
Thanks!
Just finished making 16 of these based on this fantastic video. Bought the plans and modified slightly - wouldn't really attempt it without the plans. Made them out of hard maple readily available to me. They were very time consuming, but ultimately well worth it. Work incredibly well. One mod I made was to add a 3" long 1/4-20 hex bolt through the bottom of the headstock and naturally the steel conduit bar. Adds an incredible amount of extra stability to the headstock under clamping pressure. Grab the 15/16th drill bits from harbor freight if you can. Great deal and the they work very well. I would def recommend giving these a shot is thinking about it...
That is awesome to hear! Thanks for the added suggestions as well. Did you make all yours the same length? Several years in, mine are still working well. Gotta scrape glue off em from time to time and some slide better than others, but still really happy with these.
@@GeeksWoodShop Yeah, I'm a little worried about the glue too. I've been toying with the idea of double sided taping some thin HDPE plastic to the faces. I also know what you mean about the sliding. They're not all equal, but work well enough. I'm still super impressed with how sturdy and effective they are. I ended up making 8 x 24" and 8 x 48". The beauty of the 1/4" bolt to hold the headstock and ends on is that if I REALLY want/need to, I can disassemble the clamp and reassemble on longer conduit. I'm sure the day will come...
@@andrewfergus7562 Ah nice, a bit of future flexibility built in. Hope you get lotsa years from them, with the hard maple you used they'll probably outlast mine. ;)
How does the clamp actually work? Is it steel against an aluminum bar? Does it gall up the bar and ruin it over time?
Thank you for sharing. I am just getting into wood working, But I am addicted already. I know these will make my future a lot easier, Straight forward and fairly easy to make.
It's an incredible hobby for sure, good luck!
I love Bellevue woodshop. The guy is pretty ingenious. But I like the fact that you took something here and made it look that much easier. Explaining it with a little more detail is very helpful. Not saying that Bellevue woodshop didn't, just that, it's different nuances. Great job man.
Ya, Roy is on another level entirely. I love seeing his ingenious solutions and creations. Thanks Tony.
Thanks so much for share this "Great video" with us. Great video!!
Man, THANK YOU VERY MUCH for sharing your work, experience and, above all, your mistakes. It is from that that we all learn. Great Video and great job!!! Thank you!!!!
One suggestion: When you have to glue or nail something that barely touches another element, instead of eyeballing, use shims. Scocth tape or a piece of can, whatever gives you the right clearance, that can be removed and, still, gives you a consistent and repeatable measure for all the pieces in a quick way.
Thanks, good suggestion for sure, anything that makes for accurate repeatability is worth doing. Cheers!
Thanks for the kind shoutout, it is much appreciated. Your clamps came out great. A real mass production:):). Good tip on the CA glue to position the grabber. Great video, and from the comments you wrote, it looks like yours, as mine, still hold up after much use.
Thank you for the original design, these have been such a great addition to the shop.
I like your style, mannerism AND your shop!
Thanks much, I think I've moved since this video, so rocking a whole new garage shop! Woot!
Excellent technique on centering at 15:00
This video is excellent. Thank you for sharing it with the us. I'm gonna give it a shot. Hopefully my clamps look as good as yours. I will say that a great trend I've noticed throughout my years as a woodworker, DIY'ER is that we appreciate each other's work and we are quick to let everyone know where the ideas originally came from and we send a "shout-out " to the creator. I can't tell you how much I respect that. new subscriber, look forward to flipping through your videos and can't wait for any future projects. Take care my friend. send my appreciation from Moorpark, CA
That was extremely honest of you to explain what you did wrong and what you should or could have. I subbed and liked because it's quite refreshing to see and hear these comments where a lot of people would have edited them out. So thank you and I will attempt to make some of these clamps with the limited tools I have. Looks like a very satisfying project. Many thanks and keep up the good work. I'm looking forward to your next venture. Regards, Chris.
Thanks, every project has mistakes, ya? At least every one of mine... ;) .
Just found your channel...excellent job on showing how to build DIY clamps. Thank you.
This is the best tutorial on this topic I found. GREAT job!!
Very kind, many thanks.
Very nicely done. Thank you for sharing your talent
Thank you
I followed this from Lumber Jocks and love the idea. Thanks for showing the build.
+John Hurrell Thanks!
I really like the way you think things thru. very thoughtful!
Very good equipment
Tolles Video über die Herstellung dieser Paralellklemme. Besser als das Original und die Arbeitsschritte sind besser nachvollziehbar. Mach weiter so.
Update: Habe jetzt die ersten 6 Klemmen selber hergestellt. Ich habe 20 mm ALU Rohr verwandt. Für meine Zwecke sollte das reichen. Ersten Bretter wurden schon damit zusammen geleimt. Ich habe Hutmuttern verwandt - rudi-ac.blogspot.com/2020/02/leimzwingen-jetzt-die-richtigen.html
Nice clamps, good job - congratulations
Thanks for this, I may try to build one. You have an amazing mancave there, I even see pretty 788.. yes, I am a scroller as well. The plans for the clamps are not free..but you explained it out so clearly, with a calm voice, here in your video, I may try to build my own clamps.
Thanks. Good luck if you do!
Rather than working with such small pieces when ripping them, quite dangerous, make all your rabbet cuts when the piece is full length, much safer!
You finally figured out how to cut those angles on the blocks. You drew the line on the sled at the correct angle, but didn't make a scrap at that same angle to use as a stop until later!
Agreed, order of operations sometimes means I don't anticipate the best approach and have to improvise. Good thoughts, thanks.
Nice video with the stop motion, cool design of the clamps. Hope to see more!
This video is even better the second time! Thanks so much, man. I'm definitely getting the plans, and I'll use your interpretations as well. Great stuff!
Very good video. Thanks also for sharing your thoghts and mistakes.
I'm so happy for you for all the views on this vid!! Also great job on 4K subs!!
If it weren't for making mistakes we would probably never learn a darned thing.
Thanks for the video. I'll make some more clamps of my own to add to my 35+ clamps I already have.
Thanks. Mistakes are good, I definitely prefer them in the past though. Good luck making more!
Fantastic build. Love the step-by-step approach. You make it look so easy and your narration was on point. Off to making some for my shop. Cheers!
Just wanted to follow up on my comment from last year. How are those clamps holding up? I'm finally going to get around to making some for my shop. Just curious.
VERY good show kind Sir. Love it. Gunna do it for sure. Thanks.
I've been wanting to build these for awhile. I like your take on them.
Thanks. I put up dimensioned drawings at the end of the video if you do try to build them, may be useful. Good luck!
Nice vid, and you've got some sweet machines for garage shop! If you haven't discovered them yet, step drills are great for drilling large holes in thin stock in one go with accuracy and without grabbing. They'll even chamfer the edge in a single pass. Don't bother with the cheap-o step drills or extra coatings. It's worth spending the money on good ones, and they are easy to sharpen. A good quality 3/16" to 7/8" stepper in 8 or 12 steps will probably set you back $40, but if you take care of it, it could last you your entire life.
Thanks, good advice indeed.
Great use of table saw, sled, band saw. Due to my experience as a rough carpenter and my need to conserved space, I am using only hand-electric tools... wormdrive Skilsaw, Bosch Jigsaw... now I need to find the best way to mount the Skilsaw to use as a table saw and sled (the Jigsaw is easy to setup).
Great video. Very good job editing, and voice-over. I have one suggestion. When cutting the "rabbits", cut the short cut first, then the longer cut. I will be building some of these clamps. Thanks.
Thanks for the suggestion, good luck making yours!
Great technology...
Awesome video, well done
Amazing, congratulations!!!!!!!
Great Video. Good Narration too. Finding the Center: I imagine you know by now, but, straight edge marks across both corners of a square end, where the lines intersect in the middle is the center, then, just adjust your drill table/jig to find the center mark.. What you did works good on round stock though, but, you can rotate and put a pencil in the chuck and keep moving it until you get a dot, or a circle the size of your drill bit and you are done...
I am wondering what lengths you use most in what you are making,, and, if you don't mind, look at the washers and tell me if the washer is not cone shaped in the center of some you have used.. Seems that putting them on the end of a pipe and tapping them with a ball pein hammer, or a large punch would cone shape them for the head of the nuts.. Probably why he ground his rounded on the Bellevue build.
If the washers coned out, the round would move better. You might have had some catching on the ones that were bending into cone shapes..
Excellent video.. I'll check out the channel and see what you have been up to since May of 2016.. Cheers!!
The wood you got was hard wood i presume Can You make the clamps in soft wood because hard wood in the UK is so expensive and i am only a DIY man with a little workshop Great video everything explained so well you sound like a man who really enjoys his work I have subscribed and looking forward to more. Thank you very much
I hear your pain, great lumber is hard to come by for many of us.
I'm not sure the type of wood I used, but pretty sure it's not too hard, so yes, I think you could use a softer wood, but before making too many I'd definitely make one block, drill the pipe hole in it and try to break it to see how well it holds up, that's where the strength needs to be. Good luck!
this was fantastic man thank you
Thank you man. This looks awesome. I think I can do this. Have a great day.
Geeks Wood Shop I like your work
i"ll be making a few different size myself. great build. and great presentation
I enjoyed your video. Very instructive!
You don't mention the tap that you are using. It is called (among other things) a "gun" tap, because the bevel at the beginning of the tap is ground such that the cut portions are pushed ahead of the tap as it goes into the material. If you were using a standard 4-flute tap that you normally purchase at the hardware store, it would plug up and you would either back out several times in the length that you are tapping to clear the flutes or risk breaking the tap, even in wood. It also helps to wax the tap before you start tapping, similar to oiling a tap when tapping metal. The wax sticks used to lubricate band saw blades works well. Richard Solomon's suggestion for using the drill press to start is a good idea as well. With your gun tap, and a through tapped hole, if your drill press goes slow enough, you could go all the way with the drill press. Slow enough means 100 to 200 rpm (most drill presses don't go that slow) and use a good, well clamped vise to secure it. Good video. I liked this one.
Thanks for the insights, good suggestions.
great video. I have the plans and did not end up being able to make them. I got frustrated with the metal piece as well as matching the drill bit size to the conduit size. If you have something like the conduit part number and the drill bit dimension you ended up using I'd find that helpful. great video, glad I found your channel!
I used 3/4 conduit from HDepot, which ended up with an exterior dimension of 15/16ths, so I had to buy a drill bit of just that size and it worked perfectly. Definitely measure whatever pipe you end up using.
The metal piece was frustrating, but mostly as I don't have much experience with metal. I should have drilled successively larger holes rather than trying to do it in one pass. I ruined the drill bit. :)
Awesome job
Great video, and is EXACTLY what I was looking for! Thank you for sharing your experience and process on this! Best of Luck with you channel :)
Don't use conduit friend, for clamps. It bends easily.
Gentlemen!
Buy an angle grinder! They are cheap and they make cutting steel a breeze! Just clean up the burr when you're done.
Pro tip, start all the taping by hand in the drill press (power off, turn the tap in by turning the chuck or upper pulley by hand) this will give you exact alignment.
Don't pull with a file, push. Pulling while in contact with the material is a good way to dull a file.
Fantastic build and great video!
thank you brother, i am from indonesia.
Beyond good
First time I have seen one of your videos and I enjoyed watching it.
At first I thought it was strange that you kept chuckling in the commentary but by the end, every time you chuckled it made me do the same. :)
Great vid, nice one.
P.S. For those of us who don't use SketchUp, perhaps the plan for the mirrored cut would be cool?
Gotta laugh at your own mistakes or at least try to.. I make lots of mistakes.. ;)
Perfect thanks
Planning to make some myself. Nice job. Subbed your channel.
Nice video, channel looks very promising. I have subscribed and look forward too your videos!!!
Ditto to you!
Your videos are really nice. Thank a lot for shared your knowledge. When will see more? I will be attentive. Thank you so much
The best way i know to cut such a big hole is the hole saw bit.
15/16 inch is 24mm which sounds right.
Do not know if you have been told this before but all electrical conduit and is the inside diameter like plumbing pipe..only refrigeration copper is outside diameter as far as i know o am sure there are other exceptions.
Thanks. I don't know much about pipe diameters. Good insights.
really well executed!! one more subscriber :D
Great video. I like your style. I think it would be interesting to do a test to somehow show whether clamping pressure is even across the entire clamping surface. My concern with a more dynamic material like wood is that clamping pressure might differ between locations down in the throat of the clamp and out at the tips of clamp surface. What do you think?
Thanks. It's a good question, and I don't know for sure. I've used these primarily for panel glue ups, so it doesn't test the full length, but they do hold the parallel positioning well and as best I can tell they clamp evenly, but I've got nothing but my own (very un-scientific) opinion.
These seem to be some of the best DIY clamps I have seen, very nice finish on them and they seem to work great. How are they on clampingpower? I am thinking if you want to join wood for say a tabletop.
I've used them for panel glue-ups multiple times, which was the first reason I built them. They have lots of clamping power, won't have as much as metal/ purchased versions, and I don't try to crank down on them, but plenty still. Thanks much!
FYI - When it comes to electrical conduit it's all about the internal diameter. Sparkies want to know how much cable they can pack inside it.
Try cryo hardening of your drill bits. 24 hours in liquid nitrogen, so simple.
Nice build~!
its pretty good but you should make it small
great video I look forward to more, I'm assuming you must have some background in editing or video making because this was extremely well made i also have to make some of these clamps!
I wonder about the video side and if it's clear, so thanks. I hope you do make some, they work great.
This was very good. I have been looking for something like this for a while.
Few questions:
I wonder about the little metal grabby things against the conduit ---. How long before they begin to wear out, and do you have any ideas on making them adjustable after a wear in period, or maybe have them float?
How much pressure can the clamps handle?
Will the jaw eventually go out of square?
How are you ensuring they are parallel?
All questions you may have gotten before - maybe on lumberjocks? got a link/username there?
I don't know for sure, but I suspect the metal grabbers will last for a very long time, and the conduit that I used is simple galvanized metal, so possibly softer. As far as ensuring they are parallel, that's based on how accurately they were built, and I don't suspect they will have any problems for a long time. For now they are ~8 months old and no issues, don't know the pressure but they do work very well. I'm TysonK on lumberjocks, see ya over there!
Nice job, watchable video. Did you check them for square? How does the friction grip affect that? I think these are by far the best bar clamps I've seen.
very long long process, if you want to sale that, you sure to put a price equivalent to the clamp in the market? or more expensive than that?
This was great!
How can these be made with minimal tools small startup home shop
Buen trabajo. Destacar muy positivamente su organización y limpieza, así como la realización y elaboración del video.Le animo a continuar con esta experiencia seguro que pronto tendrá numerosos seguidores.Con su habilidad y las herramientas que posee, es evidente que nos presentará unos proyectos de mayor complejidad , interés y envergadura.Me suscribo y le reitero el ánimo a continuar.Si me lo permite le realizo una sugerencia, procure cuidar el texto de los comentarios ya que la traducción simultanea le interpreta de manera deficiente, también debe, en mi opinión, realizar los videos con menor duración porque, ya sabe, lo bueno si es breve es dos veces bueno. Le hago los comentarios en mi idioma porque por escrito es como mejor me expreso.Un saludo.
Sorry the auto-translation isn't very good, I hope the main points come across. Thanks for the suggestions.
Hi, thanks for the video even i had seen it years ago. i wanna make some clamps in the near futur and i want to know how are they performing after all these years ? thanks
GREAT video, thank you. Did you use Imperial dimensions? I'm assuming that you did since you used 3/4" conduit instead of 26mm (1"). Would you mind sharing the major dimensions?
You know you can cut conduit with a pipe cutter right?
A $5 pipe cutter that will give you a nice straight square end with a slight bevel on it.
A lot easier than a fucking jig saw.
Thanks. These seem like really nice clamps. Can we have the link to check out the site from where you got the idea please?
Really like these and the design. Two questions please.
Have the conduits flexed when pressure is applied? I'm hoping to use on a dining table of 2.5 inches thick.
Has the metal of the conduit caused any staining of wood? Is the conduit galvanized?
Thanks and I appreciate the content.
The conduit hasn't been an issue at all. After a few years, I've had two of them crack at the wood base, so I might use a harder wood if I built them again, but 2 out of all of them is pretty good I think. That said, I don't put serious pressure on them, just... "enough". . :)
Watched this several times. Great video. Have some questions about clamp pressure and the pipe bending at longer lengths. Want to try something similar and at greater lengths.
I don't know what the clamping pressure is as a measurement, only that they work really well for any project I've thrown them at. I don't have problem with bending for the shorter clamps, the longer clamps can bend if you crank down on them, but it's not been a problem as that much pressure isn't needed for my work. I have had one clamp fail in that I split the wood block, but even then it still worked, and has only happened to one. Overall, I love them.
Geeks Wood Shop awesome, thanks for the reply. Does the clamp housing rotate around the pipe or does it stay in line with the end piece.... If that makes sense. Lol
By that, I mean it's on a round pipe as opposed to a flat steel bar. I didn't see anything that kept it from pitching side to side at least some.
You are correct, the end of the clamp is fixed with a screw through the bar and block, but the main clamping structure that moves up and down the bar also rotates freely around the bar. This has never been a problem for me, in fact I've had a time or two when it was beneficial as I could clamp a vertical leg to a horizontal stretcher, but ya, if you want them to stay perfectly in line, these won't.
Geeks Wood Shop OK cool. Excellent to know. Thank you so much for your help. Again, great video.
really awesome man!! good job!! I really like also ur sliding saw fence on the table saw! it would be really super for me to get a plan for some sliding and fence for table saw..any advice? have a good one ✌
Look for 'cross cut sled', there are dozens of vids on making one, personally I referenced an older video by Eagle Lake Woodworking, and there are also a few good instructables on the topic. Definitely recommend building one!
+Geeks Wood Shop thank you very much!! I'm definitely
+Geeks Wood Shop thank you very much! ! I'm definitely gonna make one..just whenever I'll have the time for it ; )
Just came back to this video and it is still great! How are the clamps holding up after 3 years of use? Anything you would change?
Thanks. One thing that has happened to 2 of the clamps is splitting on the bottom side from the pressure, so I'd probably make the lower side a bit thicker ~1/2" and use a harder wood if I were to make them again. Overall, still great though.
Thank you! Want to build myself a set of these and feedback is invaluable. Where exactly are they splitting?
is there anything to keep the middle part of the clamp parallel to one end of the clamp or it can rotate freely?
The rotate freely, but once you set em down, the flats keep them aligned when clamping, so hasn't been much of an issue.
Sorry if this has already been answered, but what length was the conduit cut and what size washer was used. I'm trying to find washers with an outside diameter of 1" and an inside diameter larger than 1/2" so the threaded rod can move a little freely, but I just cant find the washers. The washer used looks smaller than 1". Thanks!
I cut the conduit at 3 lengths, I don't remember exactly, but something like 24" 36" and 48", most of them being the shorter versions. Whatever you need. The washer, I don't remember exactly either, but I think the threaded rod was 1/2", so I used 1/2" inside washer with the bolts to stop it. One thing I'd suggest in making these, is to use a good hardwood or make the base thicker, I love these clamps but a few of them have cracked at the base over the years. Cheers!
@@GeeksWoodShop Thank you so much for responding. I finally found washers with proper diameters. The ID was easy since the threaded rod is 1/2", but that OD was difficult. Thanks for the tip about wood splitting. I have some oak I was planning to use. In the plans he uses 1" conduit. Did you find that 3/4" is sufficient, or if you made more, would you go with 1"? Great video, by the way. Really helped with the step-by-step, I'm ready to jump in.
@@rebeccac.7695 Great! Good luck with yours. I did find that 3/4 was fine, they bend slightly under use, but also, I don't ever use these to really crank down and apply a lot of pressure, I don't find that necessary.
Cheers!
Its been a bit over 3 years. How are the clamps holding up for you? Is it worth it building them?
They've held up well, still use them. I've had 2 I think that have cracked where the wood is under pressure, so would definitely build them again but might use a denser wood, as I used some light wood that I had on hand.
What do you think it costs to make these?
i suspect that you dont see these coments anymore but just in case do you happen to still have the sketchup file for the sides? or a pdf? thanks in advance.
Show de Bola Broder,Blz!!!
What degree was the angle on the block that the turn handle is on great video brother
The shallow angle? I don't remember, but the exact angle is probably not crucial. If you need plans, do check out the description for a link to bellevuewoodshop
Great video! one question.... do you know what the cost per clamp came out to?
Never calculated it out, but I did get lucky with the wood I used, found that really cheap and with the rest of the hardware, it still probably was ~$100 for 20+ clamps. Lots of time though.. ;)
isthe best frend i like four videos you
nice
Einfach und Schnell
I actually built them. However, I must have put the metal piece on wrong, because it does not set to allow the clamp to hold pressure The more I turn the handle, it walks away.. I was sensitive to your video instructions regarding its placement. Any advice?
I've found that I too can have the clamp walk away, so I sometimes need to put a bit of down pressure while twisting the handle to get the metal clip to 'catch' on the pipe. Hope that helps. Definitely frustrating to go through the whole build and then fine they aren't working right.
Maybe the design could be refined in that respect: By making the "moving block" thicker, the angle between the metal piece and the bar could be more flat, so that the small piece really bites into the bar when tightend. Do you think this could work?
It could, though even though some of mine 'catch' a bit easier than others, they all work. Still design changes and improvements are always welcome suggestions, thanks.
I am building these too and had the same thought about the grip. My thought was too put thin notches every 1/8th and then pack the conduit with 3/4” dowel to keep the rigidity intacted.
Really good job on the video, what software do you use for video editing?
Cheers
Currently using Premiere, though have used Final Cut and it works really well. Check out Hitfilm for another option. Thanks!
did you use the same size drill bit than the diameter of the pipi for the wood and the metal ?
Yes, for me it was 15/16ths to match the pipe exactly.
Great build. So it's been almost a year since you made these. How are they holding up?
Thanks! It's actually been longer, as the video came later, so almost 2 years, they are holding up great. I would definitely make them again, though I would extend the base by another .25 or .5", to add more strength there. I've had 1 of them crack there when clamping.
@@GeeksWoodShop By extending you mean the thickness along the bar? Those clamps look great, although I would fear slipping of the metal part along the pipe, especially as pipe clamps seem to use much steeper angles of the "gripping" part...
I would not use conduit for clamps. It is made for easy bending. It will not stay straight for you.
I'm just curious if you used emt conduit or rigid conduit. emt is a bit cheaper, about 4 dollars vs 15 for rigid thanks!
Robert Lasky just used simple emt conduit pipe, the cheap stuff. Works great
perfect..
