   Epoxy is too brittle for this application. I'd try strong packing tape and using a towel, iron it on.

   I glued one back together with polyurethane glue and broadcloth. It is the feed belt for an overhead drum sander. The glue expanded thru the joint and onto the grit. I didn't care. If you want to sand with it, you probably will care. You must clamp it for several hours, too, with polyethylene film on both sides of the joint. The glue expands. You might try making a lap joint rather than butt joint. The tape used in butt joining does not last forever. Don't stock up on belts. You probably have owned the one you have too long.Cadiddlehopper

   3M makes an adhesive that was originally designed to replace rivets in the aeronautical industry, the name of it it is just a number 5200. Stronger flexible bond I ever came across!

   5200 is a semi permanent bond, and 5300 is suposed to be permanent. Don't let it cure on your skin if you want to be presentable, it's not easy to remove. I used 5300 when I was working on boats and I wanted something to stay put. I don't think 5200 was in my catalogs, but I agree, it's good stuff. For permanent non-flexing bond, System 2000 is a 2 part adhesive, which is used in the automotive industry for gluing door skins and body panels on cars and trucks. If you use this, don't throw the mixing tube in the trash, put it in water or on the ground so it can cool. The mixing/acceleration process throws off so much heat it will set paper on fire in an enclosed space. No problem with a thin film, though.

   I buy stroke sander belts from http://www.industrialabrasives.com
   Least minimum for custom sizes and great prices. Stroke sanders are great tools. I've used them on metal and wood and have used many different kinds over the past 35 years.

      Hi RickL

      Industerial  Abrasive is where I buy my stroke sanding belts. I called them about  the splice coming apart and they told me the belts were old  and the sdhesive goes bad.   I always buy the minimun so i do not have them too long. I will  usr the minimun every 6 months or so. I will try this 3M 3500 adhesive if i can find it or try ironing on hevey packaging tape.

   Have a nice day Lee

   Have you asked them to reglue the belts? They are a great company for abrasives.

   http://www.proengcorp.com/   is the place for graphite cloth. The best handblocks have a 1/4 hard felt pad between the graphite and block. I typically put lead shot to make the pad heavier so you don't have to bear down as hard.
