Model Forum / General / Models / February 2009Flat(ish) link belts
Hi. Does anyone know where I might be able to purchase (in the UK) 'sensible' lengths Fenner "PowerTwist SuperGrip Top" or maybe "PowerTwist Friction Top" belting in B or C section ? I need around 1.5m (tbc) and all I've been able to find so far is Fenner themselves who will happily sell me a box of 20m.... Link to Fenner info: http://www.fennerdrives.com/high_performance_composite_vbelts/powertwist_special _belts.asp My application is for a replacement flat drive belt for a Lorch underdrive AVI-RG lathe - I plan to use the belt 'upside-down' from the original application expectations - I'm installing it on a Boxford underdrive cabinet that came from a knackered CUD, and there's no easy way to organise belt tensioning on the final drive belt - the problem of diss-assembly to replace the belt also makes the link type rather appealing. Any comments or warnings about my intended application also gratefully received! Thanks, Youra. >Does anyone know where I might be able to purchase (in the UK) >'sensible' lengths Fenner "PowerTwist SuperGrip Top" or maybe [quoted text clipped - 15 lines] >Any comments or warnings about my intended application also gratefully >received! I replaced my ML-7 drive belts with "T-Link" belts sourced from Tony Griffiths - here: http://www.lathes.co.uk/page4.html Looks like he also keeps PowerTwist. Prices not cheap, but I guess cheaper than buying 20m... Regards, Tony >Hi. > [quoted text clipped - 21 lines] > >Youra. I am surprised, have Fenner okayed running a griptop inside out? I would have thought that you would have gone with a standard (splittable) flat belt.

Bob >I don't know how prices compare with Tony G rates. Significantly cheaper that Tony G but they only stock A and Z section. Regards, Tony Hi Richard, Specifically, no - but I've found a few posts on a US machine tool forum that suggests it works just fine for relatively light applications. The reason for not going for a standard flat belt is the ability to adjust tension by removing links - my circumstances (without my re- engineering of the cabinet) does not allow for adjustment of the spacing between the spindle and countershaft pulleys - must as in the original Boxford CUD cabinet set up. Cheers.

Doesn't time fly when you're enjoying yourself :-) They (Rugby branch) have been helpful on every occasion that I've uses them, but I've only bought V belts from them.
