In 30 plus years of engineering, I have never had advice I was happy with from them - if indeed, I managed to actually make contact with anyone "in these difficult times, our lines . . ."

Well, when you finally get through to them (after getting passed around their phone system, transferred to the wrong department and cut off twice), then what they can do is read the data sheet directly from their website for their product which you have the query on.
The same one you already downloaded...
If the application is not explicitly listed on said datasheet, the answer is apparently. "dunno".
Perhaps you get better results if you are a big customer and have a dedicated rep, but based off that experience I would suggest unless they specifically do a little bottle of something called "abrasive belt making glue", then you are probably SOL.
By comparison, Bondloc seemed a lot more helpful.
However, an alternative option might be to talk to an abrasive supplier, and ask them what jointing processes are compatible with their products.

Klingspor show some useful information on the subject, and, yes, Bondloc are very helpful.Well, when you finally get through to them (after getting passed around their phone system, transferred to the wrong department and cut off twice), then what they can do is read the data sheet directly from their website for their product which you have the query on.

Good job, really , as my belt sander is arriving today.....
We must spend in excess of £50,000 with them from my rummaging our our purchasing system - and we struggle to get a rep to talk to us, never mind a dedicated rep!
I think it's simply the name that keeps getting them enough business - who says "threadlocker" rather than "loctite" regardless of which brand actually gets handed to them.

Yes getting a good bond shouldnt be difficult, the problem will be to do it without causing a lump in the belt.
Thin nylon ripstop fabric plus rubber adhesive may do a good job.
However in my case I think it wil be easier to use belts cut from wider ones, or extend the frame such that it can take a longer belt. 610mm seems more common.
Have a pack of mixed grit Einhell belts arriving today to try.

Running the backing around the whole of the inside of the belt, with the join at 180 degrees from the abrasive belt join would make a bit of sense.
1065 mm long 25 mm wide belts are where it's at for me now......

You will need some form of heated platen above the tape and a way of pressing both tape & belt on to an anvil till everything is cold . IIRC the melting point to achieve is around 86 oC
I will be using a brass plate drilled to take a rod iin my 35 watt soldering iron and using a reasonable quality infrared digital thermometer to locate the temperature ( I'll be keeping detailed records too )

Feathered cloth side then on the other the abrasive side 10 mm diagonal cleaned space & grit removed on both the sides will allow the glue to be easily absorbed by both cleaned edges into the belt. Clamp it in place until cured.
A long diagonal joint will allow a gentler softer feed of the joined belt under the wood , a sharp butt joint glue taped up , will also work but not as well .
My limited experience is that such heat taped butted nose to nose taped joints tend to open up long before a long diagonal feathered joint on home made belts

Check the temperature Clive , though I'd not want to put my printer at risk trying it as it is in a very solid heavy temperature stable enclosure .

As a butt joint or as a feathered joint ?
Nothing as complicated as that for me. I will try a 20mm finger sander belt first, butt joint with a clothes iron as the heat source.
Probably make it inside out to make things easier.
