Reel to reel drive belts
Read here much info re reel to reel belts and the making of custom belts from a DIY O-ring source. Have seen this advertiser who recommends super glue for the join. Have any of you folks tried this and does the joint stand up the the pull involved? As part of a tiny minority I've not had much success with superglue.I see there are lots of belts for popular models but am guessing that some of my beauts may not be listed
Thanks TT |

Re: Reel to reel drive belts
O-rings are available in a multitude of dimensions, including ones that have the large diameters would would need for belts, so it should be possible to find one that fits without needing to cut it. I know when I bought O-rings to use as belts for Tandberg tape recorders, that they were available in dimensions with diameters in increments of 5-6 mm or so.
I've had good success with superglue otherwise. The same material used for O-rings is available in string form so you can take as much as you need without having to sacrifice a ready made O-ring and have a piece left over that you don't know what to do with. The resilience of the rubber means the brittle cyanoacrylite joint is not subjected to any sharp knocks. But a belt of the correct dimension is always preferable. |

Re: Reel to reel drive belts
Thanks for input. Re finding the right size I guess the trick is to find the right knowledgeable engineering supplies place where 'the man' could explore the choices in sight. eBay is probably a more scatter gun approach as one has to wade through all the adverts in hope of coming upon the right match. Am encouraged by your success with the super glue, that is if it comes to that

Re: Reel to reel drive belts
I had to replace a square section drive belt recently in a cassette recorder. I didn't have one of the right size but had some bigger ones. I cut a section out with a very sharp scalpel (it's important to get a clean, square edge) and stuck the ends together with superglue, very carefully under a magnifier. You only get one chance: trying to reposition the joint will wreck it.
The belt seems to work fine, though it hasn't been used a huge amount since then. Chris

Re: Reel to reel drive belts
May be of interest to cassette folks but there's a current eBay ad for a whole handful of various sized cassette belts - at reasonable price if I recall correctly

There seems to be some difference in belt thickness as between recorders and it's impossible to identify the size of black gunge in the Philips. I'll find some measurable but it looks about a range of 2-3 mm cross section to the naked eye. If I have to go for the o ring rope solution I'll post my experience. There's even a belt 'welding machine' sort of vulcanising gadget on ebay. We'll see TT |

Re: Reel to reel drive belts
Look for a hydraulics supplier. They have a selection of O rings.
