Homebrew Idler Tyres
So ..I'm currently sidetracked from my N1700 restoring a Sanyo Betacord VTC-5150.
Sadly although I can find a suitable belt for the idler assembly I drew a blank on the idler tyre.
So in desperation I turned to fleabay ...and purchased a 1mtr length of nitrile water/fuel hose from china ..
ID 13mm OD 18mm
I figured I hopefully can cut a slice from the end to make my own ..
anyone attempted this sort of thing before ?
The dimensions are about right ..but the variable is the rubber itself ..
consistency and hardness.
Gotta be worth a punt ?
is there an alternative ?
If so ..I havent found it yet.
I guess an 'O' ring might do the job ..but an 'O' ring isn't square section.
I've used 'O' rings before today on many and varied machines, audio and video, and they can work surprisingly well. I even keep two that I use as a test belt to drive N1700 head drums! - No idea how long they would last in regular use, and I do use two in parallel, but for a cheap and dirty test, they work fine. Agreed, the N1700 drum belt is a flat profile, but two round section 'O' rings can still deliver enough traction to spin up and test.
Nitrile might be a bit too soft and stretchy, but if it's not too difficult to gain access its fitment, there'd be no harm trying.
A couple of years back I picked up a kit of O rings from Aldi for just a few bucks. Very useful!
