Brush restoration

[Ebonysw45]

Make sure to drill a hole big enough to get the cutter in, which mean you will have to do 3 or 4 holes and join them up. Now you can use the cutter to enlarge the hole.

You then turn the dremel to the side on the workstation and work the interior of the brush handle with the sanding drum to finish off.

Then I used a little wet/dry 400 grit sandpaper to smooth out the remaining area.

 

[Ebonysw45]

I had a Muhle Fibre Silvertip on hand and just gave the brush a light buff with plastx and finished with some wax. I might give it a treatment with some sandpaper 1500 or 2000 grit, maybe.

Before buff.

 

[Ebonysw45]

After.

I now need to finish off the remaining brushes using the same technique and order some more knots. I did both the Rubberset brushes, starting with the one sans knot. I only had to get through the shelf on that one and then emboldened I did the full removal on the other one.

 

[Ebonysw45]

The knot is currently not epoxied in since Im still on the fence about further work. I'll make up my mind after my forthcoming hike in Tasmania and then conclude with either the extra sanding and then fixing the knot with epoxy. I must say the knot feels pretty darn good. Im looking forward to a shave with it in a few weeks.

Thanks for sharing @Ebonysw45 I am about to drill out a few butterscotch brushes and send off to @Srdjan to reknot.

Cheers to the original enabler. To think, it only cost me 3 times as much as buying a brush. Luckily you sold me 4 of them. I only had to get the workstation, the vice, dremel chuck, drill bit, high speed cutter, epoxy, polishing compound etc. Means I can do more things with considerable more ease. So no losers here.

Started off a little tense but it its not too hard.

Oh, so we can all send our brushes to you now?

I'm glad that they have all ended up being made useful. That was my original plan but really just no time and then I lost interest.

Mt friend, someone has to give you competition, don't they?

Did the Ever Ready brushes today and man they are more trouble than the Rubberset.

The 150 was not too different from the Rubberset, knot and shelf had to be removed. A little more intensive. The 152c wow whole diffrernt thing.

It has 2 layers of what can only be described in expletives. 1 is tar like and sites just below the brush knot and at the base of that something like a brick in composition.

 

[Ebonysw45]

On the left the nice 150 on the right the not so not 152c. You can see the layer of tar like substance here. It gummed up my drill bit and the dremel cutter. Picked half of it out with a sharp screwdriver in the end.

 

[Ebonysw45]

The next layer seen here shredded the dremel cutter and threw sparks.

 

[Ebonysw45]

I removed the last bit like a stone mason, with a hammer and chisel.

 

[Ebonysw45]

I finished off with a sanding drum.

There was one last surprise in the the 152C.

A metal collar around the top.

 

[Ebonysw45]

I wii order some knots. Give the Ever Ready brushes a little more work and then set the knots.

 

[Ebonysw45]

In retrospect if I came across something like this again I might opt to chisel out the tar and initially leave the other substrate as a shelf depending on the loft. The Muhle didn’t fit so I assumed not having set a knot before that it wouldn’t fit either. If however it was in the way I might opt to try a masonry drill bit. I will update the thread when I get a few knots and try them for depth.

Drilled out the butterscotch brushes today using a drill press and forsnter bits.
