Thread: 3M RADIAL BRISTLE DISCS...

I just ordered a box of these in the different grits from Rio Grande to experiment on some cheap razors that are in awful shape. I'll let you know how I make out as I am planning on putting these 3/4" bad boys through the paces to see how they do.

I got mine in today and couldn't help but give them a try. They are cool tools, but not essential IMO. They do the same job as some other tools I've been using for a while now. However, they look like they will last longer; so thats a plus.

In the last picture, you can see where I moved the bristles against the...grain. Created some bad scratching, so don't do that. Also, you can see the 220 grit, then the 120, then the 80 grit progression. Cut pretty slowly too, definitely more of a satin finish giving tool than anything else.

I have purchased these recently and used them on one of my blades with hammered spine. It was working more efficiently than a glass brush. Unfortunately as usualy here in UK is limited supply of these and have located only one shop which sells them.

With flat surface it is good for takin the rust out but for pitting I think sanding will be better.

It does absolutely nothing for pitting.

I also have been experimenting with the radial bristle discs I purchased. I bought the set from 80 grit on up to 1 micron. I've only experimented with the 80 grit and the 220.

I agree completely. Worthless against pitting.

However, the 220 grit was one of the best tools I've used to date to clean up jimps. Just super. The 80 grit was too coarse IMO because on very close inspection, the 80 grit seemed to round over well defined jimps. Actually, I'm betting the 400 grit will be perfect for jimp cleaning. These work much better than a brass wire disc and leaves no brass on the jimps.

The 220 grit also worked wonders at getting the tang clean between the scales at the pivot pin without having to de-pin a razor.

I see these so far as a valuable tool in my arsenal for certain aspects of resto work.
