Flex Shaft

**drywall guy** · 11-04-2011, 05:00 PM

One of my flex sanders broke a flexi-shaft 3 weeks ago, i replaced it with a new one and it snaped again today ( it's only been used for 3 large houses since the repair ). I was wondering if the casing hose at head of the sander might be damaged inside causing the shaft to snap at the same place as before. Has this happened to anyone else ?.
Thanks for any feed back.

Yes it happened to me, I always change the casing hose as well and it should last as long as it did before.

quick guide on changing shaft in this post http://www.tapingandjointing.com/for...ght=driveshaft

we are about to start selling the driveshaft grease in syringes to make it easier to apply to the sahft and casing will let you all know the page when uploaded to site, its an ongoing issue with driveshafts but with weekly maintenance thay will last long enough to pay for themselves many times over, it sure sounds like the casing has some damage and worth replacing.

Hijacking thread a bit but think it's run it's course. Does anybody know how to get to the bearings on the head of the sander (it's a porter cable) I've looked at the plans but need some hints on how to get in there. Thanks in advance.

you pretty well always have to replace the casing at the same time as the shaft. when the shaft snaps it generally tears up the inside of the casing, causing some of the wire mesh to poke through the inside, this then snags the shaft as it spins causing it to snap. also a good idea to grease it up
