Flat Belt Fabricating and Splicing - Synthetic Belts 

Wow... thanks Clark!

Thanks Les!

Les, you put that better than I could. Incredible practicality and making things right with what is on hand. I’m humbled watching.

Leather belts work great, just not as long as the nylon core belts.

Thanks Reid. Yeah, the motorized grinder was needed for making a LOT of belts. It's made several thousand.

Hopefully... this belt is high priced but I do have a significant amount I got fairly cheap.

Back then they laced them together with leather.

Ha!

Wow... thanks. Comments like this certainly motive me to do more videos. Thank you very much!

😊 ok

Yeah... I mentioned it in the Mill Table video but did it off camera. Works great!

Please be aware this of for a specific belt type. This is a common type of belt but there are many that do not use this glue. Thanks!

Interesting... I've heard the cold glue is not as good but it might be 10% less strength and totally adequate. These are industrial belts so who knows

I can do that... I just got an Index model 40 mill that needs a belt for the power down feed. Send me an email with BELT as the subject and I'll set you up winkysworkshop@GMX.com

Thanks! I'll be doing a second video next week that covers the grinding a little better.

Your welcome

This glue is specific to the type of belt I am using so I would not recommend trying it if you are not sure what belt you are using.

Yes that would be a great application. I forgot to mention that they do well with high speeds too.

Thanks! Yeah... glue on lasts a lot longer too. The clip on are a quick fix.

Timing belts? Cool.

@@WinkysWorkshop they were toothed, and at least one use was in high end printers.

Please don't think that I'm attacking you (I'm not) or your expertise (again, I respect your superior knowledge) but I take issue with the distinction between "natural" and "synthetic". I simply don't think that it's helpful or meaningful. "Natural" means that we've observed it in something that isn't man-made. "Synthetic" implies that whatever it is has only ever been seen as the result of human activity. But it's all chemistry. Whether "natural" reactions or those performed by humans, it's the same chemistry. What really annoys me (and I'm *not* accusing you of this) is when folk assume that "natural" is "good" and "synthetic" is "bad". Some of the most toxic compounds known occur "in nature" many of the most beneficial substances that we have are "synthetic" (the covid-19 vaccines being barn-door examples). Finally, what is man but a product of nature? Isn't everything that we do "natural". The stuff that we make may not always be "good" but that doesn't mean that is "unnatural". Thanks.

@@nicholashacking381 Then take issue with Dow Corning thats their definition Thanks Have a Great Day

Googled: The name "nylons" refers to the group of plastics known as 'polyamides'. Nylons are typified by amide groups (CONH) and encompass a range of material types (e.g. Nylon 6,6; Nylon 6,12; Nylon 4,6; Nylon 6; Nylon 12 etc.), providing an extremely broad range of available properties. Me: Maybe google is wrong but I was told the same by belt suppliers.

There isn't much info out there on flat belts. Hopefully this will help.

Thanks Harold!

Thanks David!

I worked in offset. It was an interesting career.

@@WinkysWorkshop it was definitely an interesting place. I was impressed with the gold embosser. It was done at one of the few firms that were local.

The heat actives the glue and there is some kind of chemical reaction with the nylon. The belt width needs to be slightly more narrow than the flat area on the pulley. A flat area of 1.25 would be a 1" wide belt. I think the SB 9 is 1". This video has info on how to get the belt (in the description) and yes, I can make any width you need. If you can get the belt on without needing to splice your cost will be cheaper but you can do it either way. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VJ4HH_6MJcI.html

True!

Yeah, I don't like the clips but you are correct, the glue is high. However, depending on the belt length, you can usually install a glued belt for less than $60. I now sell a small amount of glue in for $5 buck. The clips don't last very long but they are convenient

There are many belts out there and they vary in construction a lot This belt is made of Polyamide (nylon) and rubber. One surface has a green rubber coating and the other side does not. What makes it confusing is that the side without the rubber is also green. Its easy to identify because the nylon is slick and the rubber is not. The primary reason this is important is that the glue will not stick to rubber. If you overlap the ends too far the you will have a loose end where the glue didn't stick.

It would work fine but please be aware that this glue and process is for nylon core belts only. They are common but there are many that are not nylon. More to come next week. Thanks!

@@WinkysWorkshop Thanks so much Mark for that clarification. I would definitely like to get on your list if you do decide to sell lengths of the nylon belts. However if you do decide not to distribute belt lengths, please provide a source where we can find some. Joel…..

@@joell439 This belt is high priced ($11.25 per ft) but I got a super good deal. Send me an email at Winkysworkshop@GMX.com with BELT as the subject.

Your welcome! Please be aware that this glue and process is for nylon core belts only. They are common but there are many that are not nylon.

Probably 1 to 1.5 HP?

@@WinkysWorkshop Actually recommend 1/2 HP.

@@RAYAR54 Cool, the only reason I asked is that mine is 1-1/4" and 1/2 HP. My Logan was 1/2 HP with a 1-inch belt

@@WinkysWorkshop Mine has a 1/3 HP with a 6-rib automotive serpentine belt. Can't remember the width, I think about 1-1/8" +/-. I have to run it with the back of the belt (smooth side) to the pulleys, otherwise, it doesn't track properly.

@@RAYAR54 That's strange about the tracking. Maybe the ribs are worn uneven. I had one of those on my South Bend for a while and it slipped a lot. It was only one inch wide but I really thought it would grip better than most and it did not. My current belt is 1.25" and does fairly well.

This is MUCH better than clips (combs). Your welcome. Please be aware that this glue only works on some belts types.

Haha...

Yes, its a slight angle and you have to adjust it to get the correct skive (grind) length. Every belt has it's own specification but it's really not super critical. Most belts are around 3/4 to 1 inch long although some thicker belts are longer. Next week I will post the video making the grinder and clarify a few thing. Judging by some of the comments I didn't do so well when talking about belt types. There are 3 types of belts. One type uses a finger joint. You put the belts in a guide that contains the belt and the belt material melts together (no glue). This is a good belt but usually has more issues with tracking. There are also a few belts that do not glue (use a clip) or use a different type of glue. My point is, this type of belt is very common but there are hundreds of belt types out there but only some use this glue.

Your welcome. Here's the info you need. You can send be questions in the email provided in the link as well. Note: I'm on vacation at the moment but will be back in the shop in about a week and will get back with you.

Yeah... the heaters are super high, hopefully you got a good deal.

Only about .015" of the surface is rubber, the rest of the belt is polyamide (a type of nylon. The glue (fixol) plus heat bonds the polyamide layer. The rubber has almost no strength. Some belts have a thicker rubber layer that can be bonded with Vulcol glue and heat but most often people trim the end of the belt and forgo the Vulcol. It leaves a little groove where the rubber is missing but the strength is unaffected.

Their are links below the video if you want to order a belt.

Haha... thanks, gotta have fun!

It's a good bonus to great videos

I can make one about 12" long if needed. What is a belt planner? There is link to belt ordering instruction below the video in the discription.

I assume you are talking about the drill press. Yes I put a raiser block on the drill press after designing the switch. I'll probably never get around to fixing this but I do agree.

.

This is true.. ha

Not that brand but a sheeter for sure. I dealt with high speed insert printing more than covers.

Be sure and watch Friday's video

You cut the belt at an angle and feed it through. Then grab the tip with plyers and pull.

Thanks for watching!

I'm not sure this applies to sanding belts. If you are talking about a drive belt be sure you get the correct type belt. It has to have a Polyamide core to work with this glue.

@@WinkysWorkshop Thanks, the measuring and clamping was a great help.

The grinder?

Yes but I will be unavailable for a week. Email is in the description of the video.

Thanks

Thanks!

true

Hello Dave, this is my plan but the current challenge is how to do this via my web store. I suspect I'll need to create a price sheet and handle each order individually. Originally I planned on buying new belt but it's ridiculously high priced ($11.25 per foot). I bought a 100 meter roll and there is another roll available (NOS) but after that I'll have to stop selling belts. I've realized there was a market for these belts for a long time but the need for a $750+ heater was an obstacle. Now the full price on this belt material is also a problem. Six years ago this belt was less than have the price.

Interesting. Switzerland is where Habasit belt it made. Maybe you can get a good price. I found a roll of old stock and got a good price. Depending on your lathe F1 might be a good choice but they make other belts that might be better.

Not that I know or. the glue activates nylon and makes the bond.

@@WinkysWorkshop thanks mate I will give it a try

You're welcome

You are welcome. Watch tomorrow video too.

Thanks

I''ll set you up.

Thanks! Yeah... glue on lasts about 50X longer.

Yes, I made a jig to do this. I can show in part 2. It just a track with a utility knife blade in it.

@@WinkysWorkshop Cool. Thanks

Thanks, hopefully next week I'll have a way to make the belts available

Yeah... another hand would be helpful

Thanks!

I suspect this glue would not work unless the timing belts are made of nylon. It's also activated with heat. At work people used super glue to glue belts. It was quick and easy and worked well for about 2 to 4 hours. Stacking machines have (for printing) are very demanding. I remember the super glue actually made the nylon get hot and smoke!

I've seen people use super glue on small, stretchy round belts and even large O-rings gluing them end-to-end. It was amazing that it worked at all, but I don't know how durable they are.

@@Bob_Adkins Super glue is amazing stuff but at least on this type belt (nylon Polyamide) it makes the nylon brittle. Not sure about o-rings but they make a round Polyurethane belt that melts together. The belt itself is fairly strong and the joint is the same as the belt. You can get it on amazon in several sizes. Its called Poly Round or Polycord.

Thanks, I love this drill press.

@@WinkysWorkshop I love old equipment in general, built to last, and usually simple.

@@ozguzzi Me too!

Thanks Andy, the hand grinder basically a copy of a commercially available grinder but it works way better with the help of a hand drill.

@@WinkysWorkshop You mentioned that it was based on a commercial grinder. I like the fact that you can cut most of the material off using the drill then finish it off more precisely by hand. I'm glad that you came up with some material. I certainly learned alot from the video.

@@andyZ3500s Yeah the hand grinder works incredibly well. Better than the commercial version actually. It didn't have the nut in the middle to drive the disk with. I couldn't believe the deal I got on the belt. This belt is premium belt. I found 2 rolls (bought one). Each roll was 2" x 100 meters long. I need to go back and buy the second roll. I paid less than 1/10th the original cost.

@@WinkysWorkshop Sounds like a good score. Your videos on the subject can open up some areas to different people in the homeshop our others just starting out and learning the ropes. As much as I looked thought catalogs on powertrain in the past I don't recall seeing much on belting. Hopefully people will purchase some from you. Maybe you could sell them cut and ground and the buyers could take over from their. If I disappear for a few days my tablet is failing rapidly I am down to 42% plugged into the wall at this point.

@@andyZ3500s Oh... good luck with the computer.

Some truth for sure
