I've been making joins like this since I was taught it back in the 90s. In low tempenvironments, contact cement works very well. If they belt is going around tight bends back and forth, CA glue can break down over time. Both CA glue and contact cement will fail if they get too warm. High temp silicone works well for high speed high temp situations. As usual, match the adhesive to the task and you'll be fine.
Another way is a V joint, cut to cloth on both sides then cut cloth out of other end then glue and put in the vise for 30-60 mins. Extremely strong joint. Great video once more Rob
I cannot express my gratitude for this information. You cannot imagine how may times Ive bit the bullet and just added another tensioner or random pulley to use up the slack. Thank you...
Honorable, Even such tiny tips are immensely valuable. May among us already know many. These saves lots of frustrating hour and money for those who still didn't find a suitable one. Thank you so much to document essential workhop tips for the generations to come, or even for some idiot older like me too. Love you man. God bless you.
I have a scarf joint on the flat belt used on my Southbend lathe. A lot quieter than the old lacing method. For V belts I often use link belts these days. Not cheap, but easy to change the length if needed. I purchased a replacement V belt for my milling machine and found the new belt with the same code as the old one was longer. Drat I broke down and got link belt and finally got the belt to fit. Dave.
You've just solved my problem with a drive belt for my Homemade Leslie upper/"treble" spinning speaker cone. I've sourced some Bus fan belts from the workshop at my workplace , but they were all too long. Width was OK for my re-purposed wheel/pulley, but belts were way too long for the distance between the drive motor (old drill motor) and the wheel/pulley on the rotating speaker cones. Brilliant!. Thanks Robert!
Excellent resurrection of steam age technology for new age materials -- as you, especially do so well. Some sorts of staples can be used at the joints as well. Good job, and great application and tip.
Thank you so much, your enthusiasm is contagious, and you explain everything so well! A lot of other people, have ideas that I become baffled by, as they go on in such technical and dry ways, my brain wanders off, and plays outside!! But you have such an engaging way of explaining these things, that I can take in what you say!! Grateful Thanks. Ax.
I thought about a joint where you put chain links of a bike, slightly machine it to the shape of belt's cheek, make a 0.2mm tighter hole to the pin in the belt, insert the pin with glue added. But if you say it's that stiff, would like to give it a shot one day on bicycle belt drive. You see, the problem with belt driven bikes are that they are requiring cut bike frames, which is nuts. It's more logical to cut the belt, as it is so in with the chain. Thanks for the tips Rob!
I had a problem this week with a really small belt and I tried finding a video like this and some how it's the best I found so far , I am goof with many other stuff but dryers or washing machines but ill try this tip and see if it works
Dear Mr Robert Murray-Smith, I want you to know that you are the very first person i decided to become a member on youtube at all, because I want to support what you do and thank you for that you shared so much of your knowledge so far. Even when you leave the one or other secret out in the free videos , but i get your point :). You give the chance to figure out the rest through experimenting. I Already had a ton of fun with your 1L of conductive Ink and try my selve in producing it as well because i want to build a huge battery with my little modified cell. I cant wait to see the other videos - Keep the good work up. You have true followers out there o.o/ :)
For smaller timing belts (the same kind as used in 3d printers which roll on gears with small radius) I've found that glue will crack or wear off, but melting the pieces together (heat gun, solder iron) makes it incredibly strong.
@@michaelchernoff9033 only melted the rubber. No glue, but make sure the strands overlap and embed in the rubber. 2cm overlap is plenty strong for 6mm timing belt.
Great idea! I was thinking it would be handy to use some sort of adjustable idler "tensioner" pulleys for a multipurpose dynapod. So you don't have to change the belt when switching devices.
I suspected. I just didn’t know about that scarf(?) joint. I’m likely going to be installing a belt on my laundry washer doing this. I kept thinking to myself, “This is just rubber and stuff… why can’t I use a solvent or glue to make this thing whole… even if just temporarily?” And cyanoacrylate was the first thing to come to mind. Indeed. Thank you sir for being resourceful and helpful; but most importantly, enabling me (whether right or wrong) to believe for a little while longer that I’m not bonkers. 👍
Even better than CA/superglue and contact cement is E6000 solvent-based adhesive, or Alene's "The Ultimate" adhesive. These are waterproof, permanent, and they cure flexible, just like the belt. No stiffness, and it moves over small pulleys very smoothly.
My washing machine eats through the stitches. I then switched to using balling wire, tightened with pliers until it breaks, leaving a tight ring wrapped around the two sections. Now the rubber and fabric belt material breaks as the wire is pushed into it, but at leas that lasts two washes vs 1 for thick nylon thread wrapped around generously The washing machine is a top loader with a single, very aggressive spin dry speed.
If using v belt... Look up nutlink belting.. There are other products that are similar... pretty much a stack of leather/rubber/plastic pieces. Each piece has a toggle one side, and a hole the otherside. Can join any number of pieces together to make a belt of a custom length. It brilliant for putting belts around pulleys with bearings on both sides... Think of the pavalava that's usually involved in replacing a v belt on a lathe headstock. Rather than disturbing the bearings... Just break a nutlink belt loop, feed the strip around the pulley, then reconnect into a loop.
Normal CA glue will crack and fail because it is brittle. There are some specialized CA glues that are designed to produce a flexible joint. Search for boot-fix in the green bottle. It is designed for a flexible set, not a hard acrylic set. Also, I recommend using a setting accelerator.
Hey Rob, if you speak to your friendly neighbourhood mechanics. Next time they do a timing belt replacement. They will throw away the old belt, pulleys and tensioner. If your not putting the kind of load on that a car generates, it will still last for ages. Also if they tell you the make and model of the car, replacement parts are easily sourced
I have split belts lengthways when they have multi grooves - I can't really say how long they last as I have only been using the idea for a year or two
Brilliant. For our narrow boat, it would be hard to get a standard belt and hope it was right because there are so many possible configurations in the engine bay.
@@Golo1949 I think there is some poor quality glues for sale. It should melt the rubber together but keep the joint flexible. It also depends how thick the rubber is and how you cut the joint.
Do you know if adding graphite powder to water then heating up the mixture in a microwave creates nano particles of graphene in a solution of water? If so, will the graphene become magnetic due to it's nano structure? I'm asking if this would work since you were able to make copper nano particles the same way; you always find ways to do things in the most simplistically ingenious manner.
I have done that to, but only as temporary repairs. I didnt use glue. I saw them together. I like what you did, but what about making som holes and saw a litle to?
Rob. Set up a trade page!! I'm sure many who watch your creations have access to 'waste'. I suggest £1 per transaction and the items are traded cashless. Yanno like I pay you £1 and your site connects me to someone who will send me 2x 24v 5amp PSU in exchange for 1× BLDC 10Amp motor.
it's an awesome idea mater - but no tone I will do - I don't really have much time to administer it - and it will take more administration than you think - but still an awesome idea - why don't you do it?
@@ThinkingandTinkering I have neither the time nor platform to successfully achieve this. It was somewhat a selfish suggestion. I apologise. I see daily you work all hours God sends. Thank you though, really from the bottom of my heart. Your dedication helps us all.

And I HIGHLY resonate with your Channel’s “About” section. What an excellent mission and belief.
i used to do this at work with bandsaw blades for cutting steel and alloys, superb system ,shown to me by an old friend and tutor ,
So keep your old belts and splice in the good parts. Awesome
What an awesome timely video subject... belts ARE hard to find especially on older equipment... thank you!!👍
Glad it was helpful!

I watched +20 videos of belt joining and this one is the right one.
wow - cheers mate
Thank you for this. I included a reference to your tutorial in an instructable I made on joining GT3 timing belts
Wow, that is practical and for sure saves a lot of headaches, cash, workarounds or delivery time unfitting belts may cause.
Great video! Thank you very much I just ordered a direct replacement belt for my mini lathe and of course it’s too big. This video saved me!!!
Thank you - I seen it before, long ago but had completely forgotten

did you melt the glue, or did you melt the rubber making the belt?
@@michaelchernoff9033 only melted the rubber. No glue, but make sure the strands overlap and embed in the rubber. 2cm overlap is plenty strong for 6mm timing belt.

I loved your video, i was searching for ever, I ordered Belts (riding mower belts), and too long, now I'm going to try this trick,,, Thank you so much
Thanks, I was wondering if it would be strong enough and you have answered my question, I;ll be buying belt material by the meter from now on.
Just had a test and I cannot believe how strong the joint is! Thanks.

Super Glue works quite well on rubber. Cyanoacrylates.
it does indeed

Actually all your bits are interesting.
And stick your fingers to the belt. Well that's what always happens to me when I use super glue like that.
