Link belts
I believe that the link style belts are much more effective than using the regular variety in eliminating vibrations from the motor.
Does any one know where I can buy them from and are they very expensive?
Thanks

Funny you should ask. I just inquired today about these very things. Powertwist link belt made by Fenner available at Blackwoods.
$18.90 p/foot .I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

Any transmission or bearing supply shop should be able to order in for you. Blackwoods are great for getting what you want, at the latest by the next day...... but boy do you pay for it $$$$$$. Gates make them as well as Fenner. You may want to look at getting an endless belt as well. I upgraded my flat belt on my lathe with and endless, and it cut out all vibration from that end of things. I think it is Gates, and it cost me $21.50 + GST, about a month ago.

For a benchmark comparison, Grizzly has "Power Twist" v-belts: H9815, 0.5" x 4', $29.95; H9816, 0.375" x 5', $29.95; H9817, 0.625" x 6', $41.95. Imperial dimensions, US $. For US lower 48, about $9 S&H; additional charges for international or AK & HI. Current (2007) catalog.

I am looking at getting a link belt, but what size? I have a chiwanese 12" contractor saw with one single V belt, approx 1/2" width. So is that Size "A"?

Look it up on ebay (USA), I bought 4 feet of "A" belt for about $24 plus $6 to post had it in 10 days and yes it turned my jointer into a purring machane from a jumpy vibrating one.
The US dollar is about 80 cents today so it will be cheaper than when I bought mine.

Looks like I made an error with the link, (much like my woodworking, the simple errors are the most annoying), so try this www.engineersedge.com/xbelt_size.htm or if that does not work, just copy and paste the link into the address bar

The issue with vibration is interesting. The "link belts" are made specifically for situations where the pulleys (driver & driven) are fixed and cannot be adjusted to tighten the belt. I can only assume that the V belts that are causing the vibration are of the cheaper (chinese?) variety. A properly constructed V belt should not cause the machine vibrate.

That was my initial thinking too, going back about 8-9 years. Since then, the link belts have been reported to reduce vibration almost universally, even on high quality machines. This is generally credited to the short links removing the 'V' belts tendency to get a 'memory' from sitting on and around pulleys. I suggest they are also better at allowing a little misalignment between the pulleys too, as each link can offset a little to allow for it.

The Grizzly catalog I mentioned earlier (post #5) also indicates profiles of "A" for the 1/2", "3L" for the 3/8", and "B" for the 5/8"; the 3L profile is shallow, light duty. Although pushed for reduction of vibration, Grizzly also mentions their use as a quick fix for broken belts. Not mentioned there, or here, is that they can facilitate belt replacement without dismantling the machinery. Many installations require removal of the shaft (e.g. some lathe headstock spindles and Grizzly's own bench mandrels, captured between bearing blocks) for belt replacement.
