Revo finish repair

Asked a buddy who works with composites, he told me to use an angle grinder, then re-surface with bondo. Personally I prefer using a guide coat multiple times when smoothing bondo just to make sure the surface is smooth.

Another friend works for Boeing as an adhesives and composite engineer (he developed whatever system they use for bonding the carbon fiber bodies to aluminum components in the 777) and he told me to use a wood pool cue and stop wasting his time.

Can't tell if you're trolling or serious but I'd be scared to death of using an angle grinder :smile:
 
Scuff on Revo Shaft

How about a picture of exactly what this scuff mark looks like and exactly where on the shaft this has occurred ??

An angle grinder - really ?!

Bondo - really ?!

Are we talking about a scuff mark or collision damage ??
 
You should follow up with Paul Drexler, PFD Studios, who posted a few above this post.
 
I may just take a sharpie to it. Just annoying that a new shaft got scuffed by a sloppy tip change that could have been prevented by some masking tape.

Priceless. :D
Welcome to AZ.
 
With a bit of 600 to 800 grit paper, you can draw polish it and blend it in. When changing tips on these sorts of shafts, some kind of masking I think is preferred.Then I trim the tip to the size of the ferrule/tip pad but + 1thou of an inch or 0.03mm or so. I would not use a blade over the shaft like most trim a tip to the ferrule.
If you put a dent into the shaft, the only way to fix is to use an epoxy, to fill the area, and then very carefully take it to the shafts surface. Adding carbon fillers etc won't hide it, as you can't use fillers to mimic the carbon material.

You are correct, it was certainly avoidable.

My guess is that the "scuff" can simply be burnished/polished smooth thus glossing so it is no longer noticeable. I would try burnishing with a piece leather on a lathe similar to burnishing the edge of a tip.
 
Surprised you went with such a hard tip.
I started there and dialing a few times until I settled on a SIB Pro.
The softer tip seems to pair well with such a stiff shaft.

I find the harder the tip the more spin i can get. I could easily generate spin with my z shaft because of the small diameter, but with the soft predator tip and the 12.9mm it was pretty tough to get spin. The hard tip plays much better

Revo shafts do not dent...just one of their great qualities.
