How To Repair Broken Sanding Belts

• #one

Hi gang,

Not really certain if this is the place to post this question, so if the mods want to move information technology, please do.

I have 4 types of chugalug sanders, i six"x48" Craftsman, 1 1"x42" Delta, ane iii/4"x21" air sander, & one 3"x24" Rockwell belt sander, for each of which I take purchased belts. Now information technology seems when I go to use these diverse sanders, the belts keep breaking apart at the glued joint. The belts are yet like new, simply the joints are separating.

I have tried CA glue, but that is too potent and the joint breaks again.

Belts are expensive, and I demand to use what I have, if I can. Any advice volition be appreciated.

Help!

Aloha, Tony

Maybe some kind of contact cement?

Who did you purchase the belts from? Maybe you should contact the makers and ask them what to do, in that location could have been a batch of bad belts?

Or at least they should be able to advise a glue.

• #3

I know that this may seem a silly question to ask but with some of the belts I have used in the by they take arrows as belts are directional and if they go the wrong mode they tend to come up apart at the glue joint. Are they on the correct way?

• #4

i`ve never had any luck trying to re-glue belts....seems equally though age/humidity affects the gum so i don`t effort to stock to many.
old busted belts are good for the lathe

All good input and so far. You might... try keeping one belt in the refrigerator from brand-new until you use information technology, merely to see if it's the humidity that's getting to the joint. If the manufacturer has a large proper name, you might contact them & encounter if they either take more than suggestions or will outright replace your belts as defective. Do check the arrows on the back - the arrows need to point in the management of belt travel.

The only other thing I can offer is looking at the platen behind each of the belts - if the chugalug is catching on a sharp platen border, it may peel the belt apart from the inside out.

I'yard non sure I've ever seen a belt unglue itself... I've worn quite a lot of belts completely out, till they're smooth (I compression pennies till you can encounter lite through 'em), just never had 1 come apart that way. Rip lengthwise, yes - but not come autonomously.

I'm not sure I've ever seen a belt unglue itself...

i don`t have delamination troubles with belts on my widebelt or edge sander simply the 6x48 and handheld 3x24 i frequently get `em so hot the glue will let become.

Tony,
I had a like issue recently with Klingspor belts. I contacted the company and they confirmed that the belts have a shelf life of about ii years. Needless to say, my belts were older than that.

I haven't tried it, but maybe some sort of strapping record (with the strands in it) might piece of work. Virtually of my belts were originally put together with tape.

FWIW, Wes

Thanks Stu, Drew, Tod, Tim & Wes.

I will try finding the manufacturers and inquire. Good proffer, Stu.

Yup Drew, Lap articulation belts have arrows, so the articulation does not catch on the platen. I make sure I have them correctly installed.

Tod & Wes, I had heard that the shelf life of belts is not at all too long. If I save my broken belts for my lathe work, I volition have to live to be 100 (simply 31 and ane/two more than years) and I still might have a few left. Wes, I am thinking that the tape used to bring together these belts looks a lot like fiberglas strapping record. I wonder if that agglutinative would be stiff enough? Got to try that 1.

Tim, I never thought of refrigerating a new 1 to compare. Good tip to try. Aye, I have made sure all surfaces the belts contact are smooth and free of burrs and such. No catches, until the belt starts coming autonomously. (I really did hear i start and turned the sander off quickly, to find that information technology was indeed only the gum letting go. No tearing, no destruction of the articulation tape)

I got another sguuestion from another forum to attempt mylar tape. Maybe? I am also wondering if the joints might be held together past a heat activated adhesive.

Lots more to await into.

Thank you and Aloha, Tony

Tony,
One matter you might endeavor is putting duct record on the within of the belts. My son used to do that when he did torso piece of work and information technology made them last longer.

• #ten

Long ago I made upwards a belt for my stroke sander using an "iron on knee joint patch" as the splice fabric. I selected a nylon i then it was nice and thin.

• #11

Thank you Bryan,

I've been thinking that the "tape" used on the joints of the belts I have (which looks like a material that could be nylon) were peradventure attached with a estrus activated agglutinative.

I'll have to check somewhere for the knee joint patch material and endeavor it. You didn't say how well it worked for you though????:

Aloha, Tony

Thanks Bryan,

I've been thinking that the "tape" used on the joints of the belts I have (which looks similar a material that could be nylon) were possibly attached with a oestrus activated adhesive.

I'll have to check somewhere for the knee patch textile and attempt it. You didn't say how well it worked for you though????:

Aloha, Tony

Never came autonomously.I used the whole patch, trimming off the over hang. Sewing shop/ fabric store should have them, fifty-fifty walmart should sell iron on patches.I got mine at the local corner store. I should add that that was twenty years agone, perhaps they don't take such things at present.

• #thirteen

I should add that that was twenty years ago, maybe they don't have such things now.

Oh yous betcha - they have them still. With a 7 year old male child, I can vouch for the patches they sell at Walmart. He manages to blow holes in every brand of jeans out there (fifty-fifty Toughskins).

The key is to preheat the surface, then fe them on. I have not had one patch let loose yet. Interesting solution; I wouldn't have thought of them for belts.

Purchase better belts. I utilise solely 3M abrasives. I buy them because they're made in Minnesota, or at to the lowest degree by a company owned in Minnesota. Moral of the story I've never had one come apart.

• #15

Hi Karl,

I too believe in 3M products, but I think they would have the same problem, with age. How long do y'all keep your belts? I don't have any (at this time) but have used them before. They never got one-time enough to practise what is happening to the belts I accept now (which are Norton & other brands that I don't recall correct at present) These are non cheap brand belts, simply they are non fresh. The abrasive is good and lasted a long time on the belts I got to utilise before these started coming autonomously. The actual belt itself is not in question, just the splice adhesive. I am trying to find a practiced gum to work on this application. Information technology merely has to be quite flexible, and have very strong shear strength. (Non too much to inquire for?)

Cheers all, for the suggestions. I'll exist trying near of the practiced ones.

Aloha, Tony

• #sixteen

I'd exist surprised if any belt that has been used sits in my shop for more than a calendar month. Historic period never really occured to me equally beingness a factor I guess.

• #17

Agreed on the bump.

I like the iron on patch post.

I will be trying that myself.

Two years? Interesting. I never had a separation problem like that until recently with my ane"X42" belt sander/grinder. Aye, the belts are over ii years former. They ordinarily concluding a long time in use so I never consumed my supply on hand. What should nosotros do? Buy only ane at a time from Lowe'southward or HD instead of a quantity at lower cost from Klingspore?

• #19

I've tried, and never had practiced luck putting them back together. I now will simply buy a sanding belt if I program to employ it presently. Belts over a couple of years old will virtually certainly neglect when yous try to utilise information technology. I take a few pieces of 3/iv" plywood about the width of the belts that I insert in out-of-date belts and employ them as de-fuzzing/de-burring sanding sticks. This is the simply way that I've been successful in making utilise of them without their seam declining.

Recently I bought a bottle of LePage 100% gum and am impressed on how well it works. Information technology needs to dry out 21 or 24 hours, but it does stay flexible. Haven't ried it on sanding belts though.
